Answer: The correct answer is a.

Uranium-236 is intermediate nuclei created by fusion reactions an unstable isotopes of uranium created from four hydrogen atoms used in the H - bomb .

Following is the reaction involved in above process :

²³⁵U + ¹n = ²³⁶U = ¹⁴⁴Ba + ⁸⁹ Kr + 3¹n + 177 MeV

Here ,

²³⁵U = Fision Material ,

¹n = projectile ,

²³⁶U = Intermediate Nuclei

¹⁴⁴Ba and ⁸⁹ Kr = Fission product

You have 350 mL of 3.4 M hydrochloric acid (HCl). How many grams of HCl gas are dissolved? Bonus: what is the volume of the HCl

Crank

Answer:

1. 43.44g of HCl

2. 26.67 L of HCl

Explanation:

1) Molarity of a solution = number of moles (n) ÷ Volume (V)

According to the provided information in this question,

V = 350 mL = 350/1000 = 0.350L

Molarity = 3.4 M

Using Molarity = n/V

3.4 = n/0.350

n = 3.4 × 0.350

n = 1.19mol

Using the formula below to calculate the mass of HCl;

mole = mass/molar mass

Molar mass of HCl = 1 + 35.5 = 36.5g/mol

mole = mass/MM

mass = 1.19 mol × 36.5g/mol

mass = 43.44g of HCl

2) At STP, HCl has a pressure of 1atm, a temperature of 273K

V = ?

n = 1.19 mol

R = 0.0821 Latm/molK

Using PV = nRT

V = nRT/P

V = 1.19 × 0.0821 × 273/1

Volume = 26.67L
