Answers

Answer 1

Answer:

A

Explanation:

Correct on edge

Answer 2

The temperature and moles of gas constants would most likely be filled in the first row of the table. Therefore, option A is correct.

What is gas constant ?

The gas constant, denoted by R, is a physical constant that is expressed in terms of units of energy per temperature increment per mole. It's also referred to as the ideal gas constant, the molar gas constant, or the universal gas constant.

A general constant in the equation of state of gases that is equal to the product of the pressure and volume of one mole divided by the absolute temperature in the case of an ideal gas see gas law sense c.

All gases adapt an equation of state known as the ideal gas law: PV = nRT, where n is the number of moles of the gas and R is the universal gas constant.

Thus, option A is correct.

Decide whether the compound is ionic or molecular, if you can.

Compound is a soft waxy white solid that can be easily shaped and molded by hand. When the flame of an ordinary laboratory burner is held about away from the solid, it rapidly and extensively melts into a clear liquid.

Answers

Answer:

Molecular solid

Explanation:

Molecular solids have a very low melting point. This is because, they are composed of weak intermolecular forces hence the layers of the solid easily fall apart as the solid melts.

We can see here that the solid being considered melts easily. Hence we can conclude that it is actually a molecular solid.

Assign oxidation numbers to the element in each of the following compounds. Remember an oxidation number is for one atom of the element.

a. HgO
b. Al4C3
c. CrF2
d. Fe2S3

Answers

Answer:

a.  x = + 2

b.  x = + 3

c.  x = + 2

d.  x = + 3

Explanation:

The oxidation number is a formal charge assigned to an atom present in a molecule or formula unit or ion based on some arbitrary rules.

a.

HgO

The oxidation number of Hg in HgO is:

x + (-2) = 0

x = +2

b.

Al₄C₃

The oxidation number of Al in Al₄C₃ is:

4x +(3 × -4) = 0

4x - 12 = 0

4x = +12

x = 12/4

x = +3

c. CrF₂

x + ( 2 × - 1) = 0

x - 2 = 0

x = + 2

d. Fe₂S₃

2x + ( 3 × - 2) = 0

2x + (-6) = 0

2x = 6

x = 6/2

x = +3

WHICH ONE IS TRUE WHICH ONE IS FALSE?
The number of valence electrons decreases from left to right across each period.
The number of valence electrons increases from top to bottom within each group.
All of the elements in group 9 have nine valence electrons.
Elements with the most valence electrons are in group 18.

Answers

Answer:

The number of valence electrons increases from top to bottom within each group.

Explanation:

The valence electrons are the outermost shell electrons.

Therefore, the number of valence electrons does not increase from top to bottom within each of the group.

Down a group, the number of valence electrons remains the same.

For group I elements, the number of electrons is 1.

 The group is the vertical arrangement of elements.

From left to right across a period, the number of valence electrons increases because you move from group to group.

11. A 4.175 gram sample of a certain hydrate of copper (II) sulfate, CuSO,• xH,O, is heated until all
the water is driven off. The resulting anhydrous compound weighs 3.120 grams. What is the
formula of the hydrate?

Answers

The  formula of the hydrate = CuSO₄• 3H₂O

Further explanation

Given

4.175 grams sample CuSO₄• xH₂O

3.120 grams anhydrous compound CuSO₄

Required

The formula

Solution

mass of H₂O driven off :

= 4.175 - 3.12

= 1.055 g

MW CuSO₄ = 159.5 g/mol

MW H₂O = 18 g/mol

mol ratio of CuSO₄ : H₂O :

= 3.12/159.5 : 1.055/18

= 0.01956 : 0.05861

= 1 : 3

Based on the data provided, the formula of the hydrated salt is CuSO4.3H20

What is the formula of the hydrate?

The formula of the hydrate is determined from the mole ratio of the anhydrous saltand water.

Mass of water = 4.175 - 3.120

mass of water = 1.055 g

Mole ratio= mass/molar mass

molar mass of CuSO4 = 160 g/mol

molar mass of H2O = 18 g/mol

CuSO4 = 3.120/160 = 0.0195

H2O = 1.055/18 = 0.0586

CuSO4 = 0.0195/0.0195 = 1

H2O = 0.0586/0.0195 = 3

Therefore, the formula of the hydrated salt is CuSO4.3H20
