13} Absolute dating
14} The main causes of water pollution are most often man made andcaused by increasing industrialization and human activities. Mostly the water bodies get polluted with municipal, industrial and agricultural waste and their unplanned leaking, run off, dumping and disposal.
15} Removing some of the overpopulated animals from a forest
16} mechanical and chemical
17} Yes, rocks at the surface can change from any type to igneous
18} There are two main methods determining a fossils age, relative dating and absolute dating. Relative dating is ... For example if you have a fossil trilobite and it was found in the Wheeler Formation. The Wheeler ... Scientists can use certain types of fossils referred to as index fossils to assist in relative dating

What would the Net Ionic Equation be for the following:

marin [14]

The net equations are obtained from the double displacement of the cations and anions, then balance.

NH3(aq) + HC2H3O2 (aq) = NH4+(aq) + C2H3O2-(aq)
H+(aq) + C2H3O2-(aq) + NH3(aq) -> NH4+(aq) + C2H3O2-(aq)

2NaOH(aq) + H2SO4 (aq) = Na2SO4 (s)+ 2H2O (aq)
H2S (aq) + Ba(OH)2 (aq) = BaS (s)+ 2H2O (aq)

Boyle's law states that the pressure of a gas is always:

natka813 [3]

Answer:

d. inversely proportional to the volume of its container.

Explanation:

Boyle's law states that at constant temperature and number of moles, the pressure of the gas is inversely proportional to the volume of the gas.

Thus, P ∝ T

P is the pressure

T is the temperature

For two gases at same temperature, the law can be written as:-

${P_1}\times {V_1}={P_2}\times {V_2}$

Thus, according to the question, the answer is:- d. inversely proportional to the volume of its container.
