What room in a house is similar to the chloroplasts in a cell

Answers

Answer 1

Before we use our imaginations to try and think of a fitting room, let's take a look at what a chloroplast is.

A chloroplast is the organelle in plant-based cells responsible for energy production. Through photosynthesis (you've probably heard of this before!), they use sunlight to create energy for the plant to function.

Since the chloroplast is the energy-maker for the cell, we need to imagine a room in a house that does something like this. There's a couple things that come to my mind. Firstly, although they don't really count as rooms, something like solar panels would probably make the most sense here. Since the answer asks for a room, though, solar panels don't work.

Maybe a kitchen? The kitchen is the room where food is created, supplying energy to all the inhabitants of a house.

I hope this helped! Learning about the components of cells is a little complicated at the start, but it's definitely a very exciting topic that only gets more and more interesting the deeper you delve into it.

The strongest type of interaction that occurs between the atoms is hydrogen bond.(option c)

A hydrogen atom that is bound to a highly electronegative atom and another highly electronegative atom that is close by interact with one another to form hydrogen bonds, which are an unique kind of attractive intermolecular interactions. This process is known as hydrogen bonding.

As a result of hydrogen bonding, a hydrogen atom simultaneously forms a covalent bond with one electronegative atom and a hydrogen bond with the other. These are the prerequisites for hydrogen bonding:

1.A strongly electronegative atom connected to the hydrogen atom must be present in the molecule. The degree of polarization of the molecule increases with increasing electronegativity.

2.The electronegative atom should have a tiny size. The strength of the electrostatic attraction increases with decreasing size.

A sample of a gas has a mass of 14.2g and occupies a volume of 0.678 liters at 25 C and a pressure of 0.80 atm. what is the density of a gas under these conditions

Answers

The density of gas can change, in contrast to the density of solids or liquids. This is due to the fact that gas is not compact and that temperature and pressure have an impact on its molecules.

The formula is d = MP/RT, where d is the gas's density in kilograms per liter, M is its molar mass in grams per mole, P is its pressure in atmospheric pressure units, and R is the gas law constant. The equation demonstrates that the molar mass increases as gas density increases. The pressure and temperature parameters for the gas determine the gas's density. Gas can dramatically alter its volume with a change in pressure due to its strong compressibility. Therefore, changes in density (at low pressure) can be substantial.

Answers

The size of an ion is determined by its atomic radius, which is a measure of the size of the atom from which the ion is formed. The atomic radius of an atom is generally determined by the size of its electron cloud. The size of the electron cloud is influenced by the number of electrons and the energy levels they occupy.

Of the ions given, Li+ has the smallest atomic radius because it has the smallest number of electrons and the highest effective nuclear charge, which means that its electrons are held more closely to the nucleus. Na+, K+, and CS+ have larger atomic radii than Li+ because they have more electrons and lower effective nuclear charges, which means that their electrons are held more weakly by the nucleus.

Therefore, the answer is CS+ has the largest radius.

Determine the equilibrium constant Kc and the reaction quotient Qc for a reversible reaction.

Answers

Answer:

Explanation:

The equilibrium constant (Kc) is a measure of the relative concentrations of the reactants and products at equilibrium for a given chemical reaction. It is defined as the ratio of the product concentrations raised to their stoichiometric coefficients, to the reactant concentrations raised to their stoichiometric coefficients. For a general reversible reaction

aA + bB <=> cC + dD

The equilibrium constant is defined as:

Kc = [C]^c [D]^d / [A]^a [B]^b

where [X] represents the concentration of species X (in molarity units), and the superscripts on the concentrations represent the stoichiometric coefficients of the species in the balanced equation for the reaction.

The reaction quotient (Qc) is similar to the equilibrium constant, but it is calculated using the concentrations of the reactants and products at a given point in time, rather than at equilibrium. The reaction quotient is also defined as the ratio of the product concentrations raised to their stoichiometric coefficients, to the reactant concentrations raised to their stoichiometric coefficients, and is calculated using the same equation as Kc, but with the concentrations at a specific point in time, rather than at equilibrium.

Qc = [C]^c [D]^d / [A]^a [B]^b

It can be used to predict the direction of reaction depending on the sign of Qc, Kc.

If Qc < Kc, the reaction will shift in the direction of products.

If Qc > Kc, the reaction will shift in the direction of reactants

If Qc = Kc, the reaction is at equilibrium.

so if it's 2H2O

that is 2xH2 which is 4 hydrogen atoms

and 2 x O which is 2 oxygen atoms )

on the left side of the equation

there are two atoms of oxygen

but on the right side there's only one atom

so in order to balance them you have to put 2 as a coefficient for H2O

H2+O2 ->2H2O

so now you have 2 hydrogen atoms on the left side and 4 on the right side

you put 2 as a coefficient for H2

and now

there's 4 hydrogen atoms on both sides

and 2 oxygen atoms on both sides

b.

Abnormal motor function usually manifests as decreased motility. Segmental resistance is usually reduced, and transit rate increases. Motility depends on stimulation via the sympathetic and parasympathetic nervous systems (and thus on the activity of the central and peripheral parts of these systems) and on the GI musculature and its intrinsic nerve plexuses. Debility, accompanied by weakness of the musculature, acute peritonitis, and hypokalemia, produces atony of the gut wall (paralytic ileus). The intestines distend with fluid and gas, and fecal output is reduced. In addition, chronic stasis of the small intestine may predispose to abnormal proliferation of microflora. Such bacterial overgrowth may cause malabsorption by injuring mucosal cells, by competing for nutrients, and by deconjugating bile salts and hydroxylating fatty acids.

What is Evaporation ?A type of vaporisation called evaporation takes place on the surface of a liquid as it transitions into the gas phase. When humidity impacts the rate of evaporation of water, for example, a high concentration of the evaporating substance in the surrounding gas considerably slows down evaporation.A liquid transforms into a gas during evaporation. It is simple to picture when puddles of rain "vanish" on a hot day or when wet clothing dries in the sun. In these instances, the liquid water is evaporating into a gas known as water vapour rather than really dissipating. Global evaporation takes place.Evaporation occurs on surfaces. The top layer of the liquid evaporates because the molecules with the highest kinetic energy escape into the air, causing it to become lighter.

How can you tell which metal is more reactive?

Answers

The reactivity of metals depends upon their position in the periodic table and their nature of undergoing chemical reactions.

The primary difference between metals is the ease with which they undergo chemical reactions. The elements toward the bottom left corner of the periodic table are the metals that are the most active in the sense of being the most reactive. Such as alkali metals like Lithium, sodium, and potassium all react with water, thus they are reactive in nature than the metals belonging to alkaline earth metals. The nature of more reactivity of alkali metals is due to larger atomic radius and low ionization energies and they have only one valence electron in its outermost shell.

The final molarity of bromide anion in the solution when of sodium bromide is dissolved in of a aqueous solution of silver nitrate is 0.59M

Given the mass of sodium bromide  (m) = 15.3g

Volume of aqueous solution of silver nitrate (V) = 250ml = 0.25L

Concentration of solution of silver nitrate (M1) = 0.40M

Let the final molarity of sodium bromide = M2

The volume of solution does not change when when sodium bromide is dissolved in it.

The aqueous solution of silver nitrate contains AgNO₃ ⇆ Ag⁺ +NO₃

Sodium bromide is dissociated as: NaBr ⇄ Na⁺ + Br ⁻

If we know the molecular weight of NaBr, we can directly calculate the ultimate molarity of the bromide ion (Br) from the molarity of NaBr by using the formula:

NaBr has a molecular weight of 102.89 g/mol.

So, M2 = (m/V) x 1mol of NaBr/Molec weight

= (15.3/0.25 )x 1 mol of NaBr/102.89 = 0.59mol/L = 0.59M
