Detail is given below.

Explanation:

Given data:

Mass of enzyme = 32 g

Volume of water = 42.50 mL

Volume of water+ enzyme = 48.0 mL

Density of enzyme = ?

Solution:

Density is equal to the mass divided by volume.

First of all we will calculate the volume of enzyme.

Volume of enzyme = (volume of water+ enzyme ) - Volume of water

Volume of enzyme = 48.0 mL - 42.50 mL

Volume of enzyme =  5.5 mL

Density of enzyme:

d = 32 g/  5.5 mL

d = 5.8 g/mL

2)

Given data:

Mass of cup = 14 g

Volume of cup = ?

Density of cup = 2 g/cm³

Solution:

Density is equal to the mass divided by volume.

Formula:

d = m/v

2 g/cm³  = 14 g/  v

v = 14 g/2 g/cm³

v = 7 cm³

3) What are the four ways to measure matter?

weight, mass, volume, density

4) Given data:

Mass of rock = 18.5 g

volume of rock = 3cm³

density of rock = ?

Solution:

Formula:

d = m/v

d  = 18.5 g/ 3cm³

v = 6.16 g/cm³

5)

Given data:

mass = 6g

density = 8 g/cm³

missing value = ?

Solution:

d = m/v

8 g/cm³ = 6g / v

v = 6g/8 g/cm³

v = 0.75cm³

6)

Given data:

Volume of liquid in cylinder = 48 mL

Volume of toy car and liquid = 52 mL

Volume of car = ?

Solution:

Volume of car = volume of of toy car and liquid - Volume of liquid in cylinder

Now we will put the values.

Volume of car = 52 mL - 48 mL

Volume of car = 4 mL

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
