Which isotope completes this nuclear reaction?

Chemistry
1 answer:
deff fn [24]3 years ago
5 0

Answer:

¹³₆C

Explanation:

The given nuclear reaction is:

          ¹⁰₅B + ₂⁴He → ᵃₙX + ₁¹H

In balancing nuclear reaction equation, the mass number which are the superscript and atomic number, the subscript on both sides of the equation must be the same.

For the mass number:

                  10 + 4 = a + 1

                  14 = a + 1

                    a = 13

For the atomic number:

             5 + 2 = n + 1

                7 = n + 1

                  n = 6

Note: n is the same as z from the equation

        therefore our atom is ¹³₆X which is an isotope of carbon, ¹³₆C

Hurricanes derive their energy from: Group of answer choices the latent heat of condensation. the latent heat of fusion. the lat
klemol [59]

Hurricanes derive their energy from the Latent heat of condensation.

Hence, Option (1) is correct answer.

<h3>What is Latent Heat ? </h3>

The heat that is released or absorbed during a phase change of a substance is known as Latent heat.

<h3>What is Hurricanes ?</h3>

Hurricanes is basically a type of storm called a tropical cyclone. These are intense low pressure areas. Hurricanes derive their energy from the latent heat of CONDENSATION.

Thus from the above conclusion we can say that Hurricanes derive their energy from the Latent heat of condensation.

Hence, Option (1) is correct answer.

The chemical equation for a reaction between K2Cr2O7 and HCl is shown. K2Cr2O7 + 14HCl → 2CrCl3 + 2KCl + 3Cl2 + 7H2O
guapka [62]

<u>Answer: </u>The correct answer is Option b.

<u>Explanation:</u>

Oxidizing agent is defined as the chemical reagent which helps the other chemical compound to get oxidized and itself gets reduced. The oxidation state for these species gets reduced because they are undergoing reduction reaction.

For the given chemical equation:

K_2Cr_2O_7+14HCl\rightarrow 2CrCl_3+2KCl+3Cl_2+7H_2O

Oxidation state of Chromium is getting reduced from +6 to +3 and oxidation state of chlorine getting increased from -1 to 0.

Hence, K_2Cr_2O_7 acts like and oxidizing agent because it is itself getting reduced to CrCl_3

Therefore, the correct answer is Option b.
