Gasoline use contributes to air pollution
Gasoline is a toxic and highly flammable liquid. The vapors given off when gasoline evaporates and the substances produced when gasoline is burned (carbon monoxide, nitrogen oxides, particulate matter, and unburned hydrocarbons) contribute to air pollution. Burning gasoline also produces carbon dioxide, a greenhouse gas.
Answer:
Conservative Properties of Seawater
Explanation:
The Conservative properties of seawater refer to those properties that cannot be altered due to the occurrence of physical, chemical and biological processes, over the large oceanic bodies. This typically comprises properties such as the temperature and also there is a high concentration of both sodium and chloride ions, which increases the salinity of the oceans.
These conservative properties occur in almost a fixed amount, or it most probably changes at a very slower rate through time. They can be considered to have a long residence time.
<span>Zn⁰(s) + CuSO4(aq) --> Zn²⁺SO4²⁻(aq) + Cu(s)
</span>Zn⁰ --- in free elements oxidation number is 0.
Zn²⁺SO4²⁻ ---- ionic compound , it has ion Zn²⁺, so oxidation number here is +2.
<span>The oxidation number of Zn changes from 0 to +2.</span>
Answer: 90 g O2
Explanation: soution attached:
Balance first the chemical equation
CH4 + O2 => CO2 +2H2O
Convert mass of CH4 to moles
Use the mole ratio of CH4 and O2 from the balanced equation.
Convert moles of O2 to mass using the molar mass of O2.
