True.

No matter what, the energy given by a substance can act as energy for something else. For example, the energy exerted by wind can be used to power a windmill, which in turn can power a generator that creates electricity. Another example can be running water, which generates energy that is used to turn a water turbine, which then generates electricity from the energy that is passing through the turbine.

That is true because the energy is converted into a more useful energy for the body.

HC1 solution is mostly water. NaOH solution is mostly water. When 50mL of HC1 is mixed with 50mL of NaOH, what is the final mass
elixir [45]
Since water has a density of about 1g/mL, and we are assuming HCl and NaOH are mostly water, the total mass of the 2 solutions is 100 g.
Due to the conservation of mass, the mass of product must equal the total mass of reactant, therefore the final mass must also be 100 g.

If you need to make 240 g lioh, how many grams of li3n must you react with excess water?
Savatey [412]
Answer is: 116,1 g of Li₃N.
Chemical reaction: Li₃N + 3H₂O → 3LiOH + NH₃.
m(LiOH) = 240g.
n(LiOH) = m(LiOH) ÷ M(LiOH).
n(LiOH) = 240 g ÷ 24 g/mol = 10 mol.
from chemical reaction: n(LiOH) : n(Li₃N) = 3 : 1.
10 mol : n(Li₃N) = 3 : 1.
n(Li₃N) = 3,33 mol.
m(Li₃N) = n(Li₃N) · M(Li₃N)
m(Li₃N) = 3,33 mol · 34,85 g/mol = 116,1 g.
