Nuclear reactions are those that involve the nucleus of an atom. Nuclear fission involves the splitting of an atomic nucleus and the formation of two distinct atomic species. Nuclear fusion is indeed the combining of two atomic nuclei in order to form a single atomic species. Therefore the answer to the question is true.
Answer:
2 51 × 10^-5mol/L
Explanation:
The concentration of hydrogen ions can be calculated using the formula below :
pH = -log [H+]
pH = 4.6
[H+] = ?
[H+] = Antilog (-4.6)
[H+] = 2 51 × 10^-5mol/L
Answer:
Molar mass of H3PO4 = 97.99 g/mol (Approx.)
Explanation:
Find:
Molar mass of H3PO4
Given;
Molar mass of H = 1.0079 g/mol
Molar mass of P = 30.974 g/mol
Molar mass of O = 15.999 g/mol
Computation:
Molar mass of H3PO4 = (1.0079)(3) + 30.974 + 15.999(4)
Molar mass of H3PO4 = 3.0237 + 30.974 + 63.996
Molar mass of H3PO4 = 97.9937
Molar mass of H3PO4 = 97.99 g/mol (Approx.)
Answer: Option (d) is the correct answer.
Explanation:
When heat is removed from water then there will be decrease in the kinetic energy of water particles. This is because on removing the heat, collisions between the particles will decrease as a result the energy will decrease. Thus, particles will stop moving randomly from one place to another.
Therefore, kinetic energy of the water particles decreases.
