Answer:
This happens when there are too many protons in the nucleus, because the positive protons repel each other. When two protons fuse together, one of them decays into a neutron. Our new nucleus now has one proton and one neutron. PLEASE MARK AS BREINLEST.
Answer:
Explanation:
<u>1) Data:</u>
a) Solute: acetone
b) Solvent: benzene
c) n (solute) = 0.863 mol
d) mass of solvent = 500 g = 0.500 Kg
e) ΔTf = 8.84 °C
f) Kf = ?
<u>2) Formulae:</u>
- Depression of freezing point: ΔTf = m . Kf
- Molality: m = n (solute) / kg solvent
<u>3) Solution:</u>
a) m = 0.863 mol / 0.500 kg = 1.726 m
b) Kf = ΔTf / m = 8.84°C / 1.726 m = 5.12 °C/m ← answer
Answer: Heat is removed from a gas, and the substance becomes a liquid.
Answer:
True
Explanation:
Here is an example: chemical properties include flammability, toxicity, acidity, reactivity. we observe the changes of these properties. Therefore, It's true.
