What is nuclear fusion what role does it play in the sun

GalinKa [24]

Answer:

Nuclear fusion is when two atomic nuclei combine and form one nucleus. Nuclear fusion generates all of the Sun's energy. Inward pulling by the Sun's gravity is counteracted by outward pushing by the Sun's nuclear fusion; this balance keeps the sun from collapsing or exploding.

A chemist needs to determine the concentration of a sulfuric acid solution by titration with a standard sodium hydroxide solutio

brilliants [131]

Explanation:

The given data is as follows.

Concentration of standard NaOH solution = 0.1922 M

Let the original acid solution concentration be x.

$M_{1}V_{1} = M_{2}V_{2}$

$x \times 25 = 250 \times M_{2}$

$M_{2} = \frac{x \times 25}{250}$

= 0.1 x M

$V_{2}$ = 10.00 mL (given)

The reaction equation is as follows.

$2NaOH + H_{2}SO_{4} \rightarrow Na_{2}SO_{4} + 2H_{2}O$

Concentration × Volume of $H_{2}SO_{4}$ = Concentration × Volume of NaOH

$\frac{M_{2}V_{2}}{n_{2}} = \frac{M_{3}V_{3}}{n_{3}}$

$\frac{0.1 x \times 10 ml}{1} = \frac{0.1922 M \times 13.68 ml}{2}$

x = 1.314 M

Therefore, we can conclude that the concentration of the original sulfuric acid solution is 1.314 M.
