Answer:

Humdity would decrease hence temprature would do the same, hence tundra are called deserts at times.

Explanation:

If you keep on decreasing the temperature without changing the air's moisture content significantly, eventually you'll reach 100 percent relative humidity, and then water vapor will start to condense to form dew.

Dew Point. When the relative humidity reaches 100 percent, dew forms. Dew point refers to the temperature at which air reaches saturation by water molecules. Warmer air can hold more water molecules, and as that warm air cools, it loses water vapor in the form of condensation.

When relative humidity reaches 100 percent or is saturated, moisture will condense, meaning the water vapor changes to liquid-vapor. Thus, the saturation level of air is related to the air's temperature.

Answer:

H2SO4 cannot be used with CaCO3 to produce CO2 gas

Explanation:

Because it does not dissolve in water- it forms a barrier on the surface of the unreacted CaCO3 which prevents any further reaction. A small volume CO2 is produced, this stops in short time.

Explanation:

The enthalpy of fusion for Al is 10.7 kJ/mol. -12.2 kJ is the energy change when 30.8 g of Al solidifies at 660°C.

The amount of energy needed to change 1 mole of substance under state change at constant temperature and pressure is called enthalpy of fusion. It is also known as Latent heat of fusion. Unit of enthalpy of fusion is kJ/mol.

To find the change in energy use this expression:

q = n ΔH

where

q = Energy change

n = number of moles

ΔH = Molar enthalpy

Number of moles (n) = [tex]\frac{\text{Given mass}}{\text{Molar mass}}[/tex]

                                  = [tex]\frac{30.8\ g}{26.98\ \text{g/mol}}[/tex]

                                  = 1.141 mol

Now put the values in above formula we get

q = - n ΔH                    [Negative sign is used because Al solidifies here]

  =  - (1.141 mol × 10.7 kJ/mol)

  = -12.2 kJ

Thus from the above conclusion we can say that The enthalpy of fusion for Al is 10.7 kJ/mol. -12.2 kJ is the energy change when 30.8 g of Al solidifies at 660°C.

The number of moles of CO₂ that is produced when burning 6.0 mol of ethanol is 12 mol.

The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.

Now we have to write the balanced equation

C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O

We can see that every 1 mole of ethanol we will get 2 mole of CO₂.

So 6.0 mol of ethanol we will get = 6.0 × 2.0

                                                       = 12 mol of CO₂

Thus from the above conclusion we can say that The number of moles of CO₂ that is produced when burning 6.0 mol of ethanol is 12 mol.

Acetate and hydrogen gas (H2) is never abundant in aerobic soils and sediments because they are tiny, highly reduced molecules that many bacteria that breathe oxygen and nitrates quickly absorb to use as fuel for energy generation. 

Hydrogen is a substrate for methanogenic archaea and, along with acetate, one of the most significant intermediates in the methanogenic breakdown of organic materials. Numerous methanogenic environments exhibit contributions of H₂ to CH₄ production that are both significantly lower and significantly higher than is considered usual. H₂ is rapidly converted in methanogenic settings due to the simultaneous generation by fermenting and syntrophic bacteria and consumption by methanogenic archaea.

Explanation:

The neutrons are the neutral sub-atomic particles present in the nucleus. The variation in the number of neutrons produces isotopes that have different atomic mass. Thus, options 1. d and 2. a are correct.

An isotope is said to be an atom of an element that have a different atomic mass but the same atomic number due to the variation in the neutrons in the nucleus. The neutrons have a neutral charge that makes the atom stable.

When a neutron is added or lost it makes the nucleus of the atom unstable leading to radioactive decay. The isotopes have the same constant number of protons in their nucleus.

The atomic number of the atom remains the same due to the stable proton number but varies the atomic mass due to the change in the number of neutrons.

The equilibrium molarity HPO²₄- = 6.2 x 10⁻⁸M See the explanation below.

The molar concentration of a certain species in a solution is known as equilibrium molarity.

The initial concentration H₃PO₄ = 0.31 M

Kₐ₁ = 6.92 x 10⁻³ (See Image 1 attached)

Kₐ₁ = [H⁺][tex]_{eq}[/tex][H₂PO₄-][tex]_{eq}[/tex] / [H₃PO₄][tex]_{eq}[/tex]

6.92⁻³ x 10 = [(x) * (x)] / (0.31 M - x)

Solving for x, x = 0.043 M

[H+] = x = 0.043 M

[H₂PO₄-] = x = 0.043 M 0.0429805

Kₐ₂ = 6.2 x 10⁻⁸

See the second attached table

Kₐ₂ = [H+][tex]_{eq}[/tex] [HPO₄²-]eq / [H₂PO₄-]eq

6.2 x 10⁻⁸ = [(0.043 M + x) * (x)] / (0.043 M - x)

Solving for x, x = 6.2 x 10⁻⁸ M

[H₂PO₄-]eq = x = 6.2 x 10⁻⁸ M

Work Shown:

Using the periodic table, we see that

These are approximations and these values are often found underneath the atomic symbol. For example, the atomic weight listed under carbon is roughly 12.011 grams. I'm rounding to 2 sig figs in those numbers listed above.

So 1 mole of CO2 is approximately 12+2*16 = 44 grams. The 2 is there since we have 2 oxygens attached to the carbon atom.

-------------------

Since 1 mole of CO2 is 44 grams, we can use that to convert from grams to moles.

11.0 grams of CO2 = (11.0 grams)*(1 mol/44 g) = (11.0/44) mol = 0.250 mol of CO2

In short,

11.0 grams of CO2 = 0.250 mol of CO2

This is approximate.

We don't need to use any of the information in the table.

Explanation:

Answer: The atoms of the solid products are tightly packed whereas those in gas are loose.

Explanation:

Atoms in the solid structure are linked to each other by strong force of attraction and they collectively form an three-dimensional structure. The binding of the atoms form the shape of the solid product. The gas exhibit free atoms in it. The atoms are not linked to one another by strong force of attraction. The atoms as a part of gas have higher energy as those present in the solid products. So, the atoms of the gas wander freely as compared to those in the solid products.

explanation: Synthetic fiber or synthetic fibre (in British English; see spelling differences) are fibers made by humans through chemical synthesis, as opposed to natural fibers that are directly derived from living organisms. They are the result of extensive research by scientists to improve upon naturally occurring animal and plant fibers. In general, synthetic fibers are created by extruding fiber-forming materials through spinnerets, forming a fiber. These are called synthetic or artificial fibers. Synthetic fibers are created by a process known as polymerization, which involves combining monomers to make a long chain or polymer. The word polymer comes from a Greek prefix "poly" which means "many" and suffix "mer" which means "single units". (Note: each single unit of a polymer is called a monomer). There are two types of polymerization: linear polymerization and cross-linked polymerization.

Answer:

5.09 x 10⁶ s⁻¹ = 5.09 x 10⁶ Hz

Explanation:

The relation between frequency (ν) and wavelength (λ) is given by:

λ = c/ν

where c is the speed of light (2.998 m/s) and it is a constant.

So, we first convert the wavelength from nanometers (nm) to meters (m) (1 nm = 1 x 10⁻⁹):

λ= 589 nm x (10⁻⁹ nm/1 m) = 5.89 x 10⁻⁷ m

Then, we calculate the frequency from the equation:

λ = c/ν ⇒ ν = c/λ = (2.998 m/s)/(5.89 x 10⁻⁷ m) = 5.09 x 10⁶s⁻¹ = 5.09 x 10⁶ Hz

Answer:

Kc = 0.333

Explanation:

First of all we state the equilibrium reaction:

C₂H₅OH(aq) + CH₃CO₂H(aq)  ⇄  CH₃CO₂C₂H₅(aq) + H₂O(l)

Initially we start with 1 mol of alcohol and 1 mol of acid. After the reaction goes complete, 0.25 moles of acid have been consumed. As ratio is 1:1, we also consumed 0.25 moles of alcohol. Then, in the product side we finally produced 0.25 moles of water and 0.25 moles of ethyl acetate.

How many moles are available in the reactant side, after the equilibrium?

1 mol - 0.25 moles (that have been reacted) = 0.75 moles.

To determine Kc, we need molar concentrations, so let's see M in products and reactants:

0.75 mol / 0.25 L = 3 M

0.25 mol / 0.25 L = 1 M

We needed to convert 0.250 mL to L → 0.250 mL . 1L/ 1000mL = 0.250 L

Let's determine expression for Kc:

Kc = [H₂O] . [CH₃CO₂C₂H₅]  / [C₂H₅OH] . [CH₃CO₂H]

1 . 1 / 3 . 3 = 1/9 → 0.333
