Answer:C.He should locate the chloroform stored in a dark container in chemical storage and should take it to the fume hood to pour.

Explanation:

The statement of the question clearly states that chloroform is sensitive to light and it's vapour is toxic.

If a substance is sensitive to light, then it must be stored in a dark bottle. This is because. If a substance that is sensitive to light is stored in a transparent container, it may be decomposed by light.

Being a substance whose fumes are toxic, Malik should pour the liquid in a fumes hood so that he does not inhale the fumes.

Answer:

I beleive its the middle/second option :)

Explanation:

Sorry if I'm wrong but Newton's third law is "for every action (force) in nature there is an equal and opposite reaction." meaning if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A so I beleive the moon would push up on the astronaut with a force of 300 N

I hope this helps, have a good day :)

Answer:

C. C₆H₁₂

Explanation:

Alkenes are the unsaturated hydrocarbons which form a homologous series with a general formula;

       Cₙ H₂ₙ

n in this problem is 6

  2n = 2 x 6 = 12

The formula of the compound will be C₆H₁₂

Answer:

A

Explanation:

Solid particles only vibrate, so they have very little kinetic energy.

For B, the size of the particles stay the same, just phase/state changes, so not B.

For C, gas particles move the fastest compared to liquid and solid given the same environment.

For D, they don't have the same kinetic energy because solid particles barely move while gas particles keep moving.

Explanation:

The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius. Three widely used definitions of atomic radius are: Van der Waals radius, ionic radius, and covalent radius

Answer:4400

I went over this problem multiple times and I finally found the soultion

The concept of significant figures are mainly used by scientist and engineer to know the significance of digits in a measurement. Therefore, 4400L is the solution to the equation rounded to the correct number of significant figures.

Significant figures are the figures that indicate the degree of accuracy of a value. It tells about the precision of a value. It gives an idea about the digits that are necessary to indicate the experimental value.

Rules for counting significant figures are:

Number between 1 to 9 is always significant

Zeroes after a number has got no significance

Zeroes before a number has got no significance

Zeroes between number has got significance

4700 L - 281.4 =4400L

Therefore, 4400L is the solution to the equation rounded to the correct number of significant figures.

Answer:

There is an overall release of energy when bonds form.

Explanation:

There is a general release of energy when bonds form. This energy is called bond energy.

Bond energy is involved in the breakdown or formation of one or more bonds between atoms of a molecule. Atoms bond with each other to achieve their electronic stability, that is, they move from a higher energy situation to a lower energy one. With this we can state that when the bond between atoms is formed, energy is released; therefore, its breakdown depends on energy absorption.

Answer:

Not all substances dissolve in all solvents

Explanation:

In chemistry, a common rule for determining if a solvent will dissolve a given solute is "like dissolves like." Solvents composed of polar molecules, such as water, dissolve other polar molecules, such as table salt, while nonpolar solvents, such as gasoline, dissolve nonpolar substances such as wax. Some substances are strong enough to not dissolve.

Answer:

273.6 g

Explanation:

mass =(density)(volume)

mass=(5.7g/cm^3 )(48 cm^3)

cancel out your cm^3 and your are left with grams

multiply (5.7g)(48)=273.6 g

The mass of an object with a density of 5.7 g/cm³ and a volume of 48 cm³ is 273.6 grams.

Density is defined as the degree to which a material is packed together.

It is also defined as a mass per unit volume of the substance.

Its SI unit is kilogram per cubic meter or  gram per meter.

Density can be expressed as

Density = mass / volume

Mass =  density x volume

As given, Density = 5.7 g/cm³

                Volume = 48 cm³

So, Mass =  5.7 g/cm³ x  48 cm³

               =  273.6 grams

Thus, the mass of an object with a density of 5.7 g/cm³ and a volume of 48 cm³ is 273.6 grams.

The IUPAC name for NO is nitric oxide. The correct option is A.

The International Union of Pure and Applied Chemistry (IUPAC) is a global organization that represents chemistry as well as related sciences and technologies.

The chemical compound's identity is represented by its common and IUPAC names, which differ from one another. Every chemical compound has multiple names.

Complete the following step-by-step response: The IUPAC nomenclature is a standardized name given to organic compounds in accordance with official naming rules.

Nitric oxide, also known as NO, is a colorless gas. It is one of the most important nitrogen oxides.

Nitric oxide is a free radical, which means it has an unpaired electron, which is sometimes represented in its chemical formula by a dot.

Thus, the correct option is A.

Answer:

Element 2

Explanation:

If we look at the model stated for element 1, it is clear that element 1 must be a noble gas. It has eight electrons in its outermost shell this implies that it has already attained a complete octet of electrons and is reluctant towards chemical reaction.

The second element belongs to group 16 since it has six electrons on its outermost shell. It is certainly more reactive than element 1 which is a noble gas.

Answer: D

Element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.

Explanation:

Each orbital within a particular sublevel is distinguished by its value of ml. This quantum number may be more aptly named the orbital orientation quantum number. In each energy sublevel (designated by l) there are 2l+1 possible independent orientations of the electron cloud.

Answer:

[tex]m_l-magnetic[/tex]

Explanation:

The principal energy level, n, tells us which shell it is in and the total energy of the electron.

The angular momentum (azimuthal), l, tells us which sublevel/subshells the electron is in.

The magnetic, m sub l, tells us the orientation the electron is spinning.

this is lithium ion with a +1 charge
