If U-235 decays into Cs-135 and 4 neutrons, what other nuclide will be produced?
dmitriy555 [2]

If U-235 decays into Cs-135 and 4 neutrons, the other nuclide that will be produced is Rb-96 (option D).

<h3>What is radioactive decay?</h3>

A radioactive decay is the process by which an unstable large nuclei emit subatomic particles and disintegrate into one or more smaller nuclei.

According to this question, a radioactive material Uranium- 235 undergoes radioactive decay into Cs- 135 and 4 neutrons (1/0n).

This means that the mass of the products we have is 135 + 4 = 139.

The mass of the nuclide left must be 235 - 139 = 96, hence, the other nuclide that will be produced is Rb-96.

What is the percent by volume of a solution formed by mixing 15 mL of hydrochloric acid into water, forming 75 mL of solution?
timama [110]

Answer:

= 17% (v/v)  

Explanation:

% by Volume = (Volume HCl / Volume of Solution)100%

= 15ml/(75ml + 15ml) x 100% = 16.66666667% (calculator answer)

= 17% (v/v)  2 sig figs. based on volume values given.
