RNA strand is called ribonucleic acid
Answer:
K₂S(s) → 2K⁺(aq) + S²⁻(aq)
Explanation:
A strong electrolyte is a compound that, in solution, dissociates completely. For a compound XₐYₙ that dissolves in water:
XₐYₙ(s) → aXⁿ⁺(aq) + nYᵃ⁻(aq)
Now, potassium sulfide (K₂S), as a strong electrolyte dissolves in water thus:
<em>K₂S(s) → 2K⁺(aq) + S²⁻(aq)</em>

Answer:
A liquid
Explanation:
Liquids has an indefinite shape, which means it could change from one shape to another. For example, if you pour water into a rectangular fish tank. The shape of the liquid changes into a rectangle. Definite volume means its volume is consistent and that it is unchangeable. If you fill the rectangular fish tank with water, the volume of the water stays the same even though it changes shape.
Hope this helps.
<span>100 g of KClO3 @ 122.55 g/mol = 0.816 moles of KClO3
by the reaction
2 KClO3 --> 2 KCl & 3 O2
0.816 moles of KClO3 @ 3 moles O2 / 2 moles KClO3 = 1.224 moles of O2 can be made
using molar mass
1.224 moles of O2 @ 32.0 g/mol =
39.2 grams of O2 can be made</span>
Answer: When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases.
