<u>Answer;</u>
B) water molecule has a bent shape.
<u>Explanation;</u>
- Water molecules are polar molecules because of their shape. Water molecules have one side that is positively charged due to hydrogen atom which is partially positive and the other side which is negatively charged, due to the oxygen atom.
- When two molecules get close to each other the polar forces of attraction brings them close to each other. Oxygen bonds with several hydrogen atoms in the other water molecules resulting to hydrogen bonds.
Yes
coz the molar mass of fluorine is 19
the molar mass of hydrogen is 1
then, HF will be 20g/mol
Well they buy food then they cook it then they eat it
Answer:
NaNO₃ and AgCl are the two products that can be formed.
Sodium nitrate, an aqueous solution and a solid silver chloride (precipitate)
Explanation:
We determine the dissociation of both salts
AgNO₃ (aq) → Ag⁺ (aq) + NO₃⁻ (aq)
NaCl (aq) → Na⁺ (aq) + Cl⁻ (aq)
We make the ionic equation:
Ag⁺ (aq) + NO₃⁻ (aq) + Na⁺ (aq) + Cl⁻ (aq) → NaNO₃(aq) + AgCl (s) ↓
When making a solution by diluting a stock solution. Suppose when a solid is stirred into a liquid and dissolves,
a homogenous mixture is formed. When the mixture does not dissolve, the mixture
is heterogeneous.
