Answer:
mineral acids are obtained from one or more inorganic compounds which is a compound that lacks carbon and hydrogen bonds. Inorganic compound examples include water and carbon dioxide. Something all mineral acids do is form hydrogen ions and the joined together bases when it is dissolved in water.

Answer:
V = 12.5 L
Explanation:
Given data:
Volume of NO = 15.0 L
Temperature and pressure = standard
Volume of nitrogen gas produced = ?
Solution:
Chemical equation:
6NO + 4NH₃ → 5N₂ + 6 H₂O
Number of moles of NO:
PV = nRT
n = PV/RT
n = 1 atm × 15.0 L / 0.0821 atm.L /mol.K × 273.15 K
n = 15.0 atm.L / 22.43 atm.L /mol
n = 0.67 mol
now we will compare the moles of No and nitrogen gas.
NO : N₂
6 : 5
0.67 : 5/6×0.67 = 0.56
Volume of nitrogen gas:
PV = nRT
1 atm × V = 0.56 mol × 0.0821 atm.L /mol.K × 273.15 K
V = 12.5 atm.L / 1 atm
V = 12.5 L
As temperatures increase, additional heat energy is applied to the constituent parts of a solid, which causes additional molecular motion. Molecules begin to push against one another and overall volume of a substance increases. When thermal energy is added to a substance, it’s temperature increases.

Explanation:
In this case, we have to keep in mind the valence electrons for each atom:
<u>N => 5 electrons</u>
<u>O => 6 electrons</u>
If the formula is 
, we will have in total:
Additionally, we have to remember that each atom must have 8 electrons. So, for <u>oxygens 5 and 3</u> we will have 3 lone pairs and 1 bond (in total 8 electrons. For oxygens, <u>6 and 4</u> we will have 2 lone pairs and 2 bonds (in total 8 electrons) and for <u>nitrogens 1 and 2</u> we will have 4 bonds (in total 8 electrons).
To find the <u>hybridization</u>, we have to count the atoms and the lone pairs around the nitrogen. We have 3 atoms and zero lone pairs. If we take into account the following rules:
With this in mind, the hybridization of nitrogen is 
.
