Answer:
Unlike alpha and beta particles, which have both energy and mass, gamma rays are pure energy. Gamma rays are similar to visible light, but have much higher energy. Gamma rays are often emitted along with alpha or beta particles during radioactive decay.

Answer:
We'll have 1.00 mol H2
Explanation:
Step 1: Data given
Number of moles of Mg = 1.00 moles
Step 2: The balanced equation
Mg(s) + H2SO4(aq) → MgSO4(aq) + H2(g)
Step 3: Calculate moles of H2
For 1 mol Mg we need 1 mol H2SO4 to produce 1 mol MgSO4 and 1 mol H2
We'll have 1.00 mol H2
Answer:
A solution exhibits colligative properties since solute interferes with the interaction of the atoms which would change certain properties of the solution. It's the freezing point that is affected. Here's how we solve it:
ΔT = kf (m) i
where kf is the freezing point depression constant which is 1.86 for water
m= molality
i= the van't hoff factor which is 2 for NaCl
ΔT = 1.86(0.321) 2
ΔT = 1.19412 °C
1.19412 °C = 0 - T
T = -1.19412 °C
Round your answer with 3 decimal places, which is -1.194°C
Hope this helps and stay safe during these crucial we will get through this!
