mL of vinegar, we have

5

mL of vinegar.

Similarly, we have

100

%

−

5

%

=

Describe the energy of the products in comparison to the energy the atoms had when the were wandering around the room free.
Over [174]

Answer: The atoms of the solid products are tightly packed whereas those in gas are loose.

Explanation:

Atoms in the solid structure are linked to each other by strong force of attraction and they collectively form an three-dimensional structure. The binding of the atoms form the shape of the solid product. The gas exhibit free atoms in it. The atoms are not linked to one another by strong force of attraction. The atoms as a part of gas have higher energy as those present in the solid products. So, the atoms of the gas wander freely as compared to those in the solid products.

What is the percentage of nitrogen, by mass, in calcium nitrate?.
SCORPION-xisa [38]

Answer:

<em>Nitrogen = 17.07%</em>

Explanation:

We are asked to calculate the percentage by mass of nitrogen in Ca(NO3)2.

The molar mass of calcium nitrate is 164,088 g/mol.

In this 164.088 g/mol there are 2 nitrogen atoms.

Molar mass of nitrogen = 14,0067 g/mol

% Nitrogen = molar mass of N/total molar mass of the compound

% Nitrogen =[(2 x 14.0067)/164.088]*100

% Nitrogen = 17.07%

Compare and contrast ionic and Covalent compounds​
Elden [556K]

Answer:

Ionic bonding occurs between atoms that have opposite needs for electrons (metals and nonmetals) and results in a transfer of electrons. Covalent bonding occurs between atoms that have similar needs for electrons (two nonmetals) and results in a sharing of electrons.
