We know that Zinc (Zn) has a molar mass of 65.39 g/mol. Hence the remaining is:

136.28 - 65.39=70.89

While molar mass of Chlorine (Cl) is 35.453 g/mol .

70.89 / 35.453 =2 => Cl

So the formula is ZnCl2

The equation for density, d, is

ss7ja [257]

Answer: The density of substance is $3.38g/cm^3$

Explanation:

To calculate density of a substance, we use the equation:

$\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}$

We are given:

Mass of substance = 61.6 g

Volume of substance = $18.2cm^3$

Putting values in above equation, we get:

$\text{Density of substance}=\frac{61.6g}{18.2cm^3}\\\\\text{Density of substance}=3.38g/cm^3$

Hence, the density of substance is $3.38g/cm^3$

Molecule of water contains hydrogen and oxygen in a 1:8 ratio by mass. This is a statement of __________.A) the law of multiple

fgiga [73]

Answer:

The correct answer is B.

Explanation:

The molecule of water has 2 atoms of hydrogen and 1 atom of oxygen.

The ratio of masses are given as:

$2\times 1 g/mol: 1\times 16 g/mol= 1 : 8$

This illustrates the law of definite proportions which is also known as law of constant compositions .

The law states that 'the elements combining to form compound always combine in a fixed ratio by their mass.'

Whereas :

Law of multiple proportion states that when two elements combine with each other to form more than one compounds , the mass of one element with respect to the fixed mass of another element are in ratio of small whole numbers.

Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.

In a balanced chemical reaction ,total mass on the reactant side must be equal to the total mass on the product side.

Law of conservation of energy states that energy can neither be created nor be destroyed but it can only be transformed from one form to another form.

Determine whether each molecule is polar or nonpolar.

JulsSmile [24]

A) Sulfur dichloride (SCl₂) is polar molecule because is bent with asymmetric charge distribution around the central atom (S).
b) Sulfur tetrachloride (SCl₄) is polar because there is lone electron pair around the sulfur.
c) Bromine pentachloride (BrCl₅) is polar because dipole moment do not cancel.

Out of Br2 and NaBr which compound is more likely to be more soluble in CCl4

saul85 [17]

Br2 because it is non polar and so is CCl4 and like molecules dissolve like molecules therefore Br2 will dissolve in CCl4
