The discrete group of atoms that are held together by sharing valence electrons

Pepsi [2]

Answer:

Molecule

Explanation:

Molecule is defined as the discrete group of atoms that are held together by sharing valence electrons.

This is because two or more atoms is known as a molecule and for electron sharing to occur then there must be a minimum of two atoms which is also known as a molecule present in the sharing process.

method to measure soluble organic carbon in seawater includes oxidation of the organic materials to CO2 with K2S2O8, followed by

dusya [7]

Answer:

The ppm carbon in the seawater is 104.01.

Explanation:

Mass of seawater = 6.234 g

Mass of carbon dioxide gas produced = 2.378 mg = 0.002378 g

1 mg = 0.001 g

Moles of carbon dioxide gas = $\frac{0.002378 g}{44.009 g/mol}=5.4034\times 10^{-5} mol$

1 mol of carbon dioxde gas has 1 mole pf carbon atoms,then $5.4034\times 10^{-5} mol$ will have ;

$1\times 5.4034\times 10^{-5} mol=5.4034\times 10^{-5} mol$ of carbon

Mass of $5.4034\times 10^{-5} mol$ of carbon ;

$12 g/mol\times 5.4034\times 10^{-5} mol=0.0006484 g$

To calculate the ppm of oxygen in sea water, we use the equation:

$\text{ppm}=\frac{\text{Mass of solute}}{\text{Mass of solution}}\times 10^6$

(Both the masses are in grams)

$=\frac{0.0006484 g}{ 6.234 g}\times 10^6=104.01 ppm$

The ppm carbon in the seawater is 104.01.

The liquid is being heated.

spayn [35]

there should be less liquid at the end of the experiment since heating liquid is an endothermic process, and endothermic processes typically break the bonds between liquids. The applied heat would soon break the bonds that hold the molecules of the liquid together, and evaporation would occur once the temperature is hot enough. Thus, the evaporated water would decrease the volume of the liquid.

Calculate the mass of oxygen gas (O2) dissolved in a 5.00 L bucket of water exposed to a pressure of 1.13 atm of air. Assume the

Ilia_Sergeevich [38]

Answer:

The mass of oxygen gas dissolved in a 5.00 L bucket of water exposed to a pressure of 1.13 atm of air is 0.04936 grams.

Explanation:

Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.

To calculate the molar solubility, we use the equation given by Henry's law, which is:

$C_{gas}=K_H\times p_{gas}$
