Answer:
Compound
Explanation:
A compound is a substance that cannot be broken down by an ordinary physical process but can be split into its component elements by chemical processes such as decomposition, dissociation, displacement.
A compound is made up of two or more different atoms. A particular compound is unique/uniform in its composition and doesn't share its particular composition with another compound. For example, carbon monoxide (CO) is made up of one atom of carbon and one atom of oxygen while carbon dioxide (CO₂) is made up of one atom of carbon and two atoms of oxygen.
Answer:
a) The molecular mass of each compound dinitrogen pentaoxide is 108 g/mol.
b) The molecular mass of each compound lead(ll) nitrat is 331 g/mol.
c) The molecular mass of each compound calcium peroxide is 72 g/mol.
Explanation:
a) Molecular mass of dinitrogen pentaoxide that be M.
Mass of nitrogen atom = 14 g/mol
Mass of oxygen atom = 16 g/mol
b) Molecular mass of lead(ll) nitrate that be M.
Mass of lead = 207 g/mol
Mass of nitrogen atom = 14 g/mol
Mass of oxygen atom = 16 g/mol
c)Molecular mass of calcium peroxide that be M.
Mass of calcium atom = 40 g/mol
Mass of oxygen atom = 16 g/mol
Answer;
A. letters to tuna companies
The use of dolphin-safe nets for catching tuna was started because of letters to tuna companies.
The use of dolphin-safe fishing methods was started because lots of dolphins were drowning in nets used to catch yellow fin tuna. The method was a new plan that the US had created in order to increase the tuna shortage that was happening in the country.
