Answer:

1.0 M is the concentration of hydrochloric acid.

Explanation:

HCl (aq) + NaOH (aq) \rightarrow H_2O (l) + NaCl (aq)

To calculate the concentration of acid, we use the equation given by neutralization reaction:

n_1M_1V_1=n_2M_2V_2

where,

n_1,M_1\text{ and }V_1 are the n-factor, molarity and volume of acid which is HCl

n_2,M_2\text{ and }V_2 are the n-factor, molarity and volume of base which is NaOH.

We are given:

n_1=1\\M_1=?\\V_1=50.0 mL\\n_2=1\\M_2=2.0 M\\V_2=25.0 mL

Putting values in above equation, we get:

1\times M_1\times 50.0 mL=1\times 2.0 M\times 25.0 mL

M_1=\frac{1\times 2.0 M\times 25 mL}{1\times 50.0 mL}=1.0M

1.0 M is the concentration of hydrochloric acid.

(58 g)/ (4L) reduce units to one
katen-ka-za [31]

Answer is 14.5 g L⁻¹.

<em>Explanation;</em>

Here, the question says reduce the units as one.

The presented units are g/L. To reduce the units to one, what we can do is take L to the upper side.

This can be done according to the rules of indices;

1 / aˣ = a⁻ˣ

Like that, we can write 1 / L as L⁻¹.

Hence, the reduced unit is g L⁻¹.

But remember to keep a space between when writing two different units.

Actually, this is an unit for density.

Burning fuels such as hydrocarbons is useful because it releases light and what kind of energy?
dimaraw [331]

Answer: Hydrocarbon fuels like methane (CH4) burn in the presence of oxygen to produce carbon dioxide and water. This process of combustion releases energy. When energy is released during the course of a chemical reaction, it is said to be an EXOTHERMIC reaction.
