Explanation:
Given that,
Volume of a hallow glass sphere is 350 mL
Specific gravity is 1.252
We need to find the weight of the sphere. The ratio of density of substance to the density of water is called specific gravity.
The density of water is 1 g/mL
We know that,
1 pound = 453.592 grams
So,
m = 0.97 lbs
So, the weight of the sphere is 0.97 lbs or 0.97 pounds.
At room temperature hydrogen chloride is a colorless gas with a sharp or pungent odor. Under pressure or at temperatures below –85°C (-121°F), it is a clear liquid.
Answer:
Living things in the ocean are able to move carbon from the atmosphere into surface waters.
Explanation:
Answer:
Explanation:
Gold (111) Chloride:
AuCl₃
The oxidation state of gold is +3.
Chlorine is present in group seventeen and have seven valance electrons . Thus it accept one electron to complete the octet and show oxidation state -1.
When it react with gold(III) three chlorine atoms are combine with one gold atom to make compound overall neutral.
Calcium Carbonate:
CaCO₃
Carbonate formula is CO₃²⁻ . It means it carry -2 charge . Calcium is present in group two. It has two valance electrons and lose them to get complete octet thus shows +2 oxidation state.
When it combine with carbonate the overall compound is neutral because -2 and +2 charges cancel each other.
Hydrobromic Acid
HBr
Hydrogen has one electron while bromine has seven valance electrons. Bromine require one more electron to complete the octet. It react with hydrogen by sharing of one electron of hydrogen and form polar covalent compound.
