It has to be dilute since the crystal dissolved and unsaturated for the same reason so B
Answer:
The volume is 4.13793 L
Explanation:
Density is a quantity that expresses the relationship between the mass and the volume of a body, so it is defined as the quotient between the mass and the volume of a body:

Density is a characteristic property of every body or substance.
The most commonly used units of density are
or
for solids, and
or
for liquids and gases.
In this case, you know:
- density= 0.87

- mass= 3.6 kg= 3,600 g (being 1 kg=1,000 g)
- volume= ?
Replacing:

Solving:

volume= 4,137.93 mL
Being 1,000 mL=1 L, then volume= 4,137.93 mL= 4.13793 L
<u><em>The volume is 4.13793 L</em></u>
Answer:
1 gram of H2 will be produced from 12 grams of Mg.
Explanation:
According to Stoichiometry, 0.5 moles of Mg are present. 1 mole of Mg produces 1 mole of H2, so 0.5 moles of Mg will produce 0.5 moles of H2. Multiplying molar mass of H2 i.e. 2 gram/mole with 0.5 moles, we can find the mass of H2 in grams which is 1 gram.
I'm not understanding that much. but if i'm right the answer is <span>3.84 x 10^-19 J</span>
I think it’s C but I’m not sure
