Answer:
The pH of the solution is 1.00
Explanation:
The pH gives us an idea of the acidity or basicity of a solution. More precisely, it indicates the concentration of H30 + ions present in said solution. The pH scale ranges from 0 to 14: from 0 to 7 corresponds to acid solutions, 7 neutral solutions and between 7 and 14 basic solutions. It is calculated as:
pH = -log (H30 +)
The concentration of the H30+ ions is 0,1M:
pH= -log (0,1)
<em>pH=1.00</em>

Answer:
Saturn's rings are made up of ice, dust, rocks, moons and other satellite that orbit the gas giant as its equator, where gravity is strongest.

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
.

Answer:

Explanation:
Hello,
In this case, the undergoing chemical reaction is:

Next, we identify the limiting reactant by computing the moles of magnesium oxide yielded by 3.86 g of magnesium and 155 mL of oxygen at the given conditions via their 2:1:2 mole ratios and the ideal gas equation:

It means that the limiting reactant is the oxygen as it yields the smallest amount of magnesium oxide. Next, we compute the mass of magnesium consumed the oxygen only:

Thus, the mass in excess is:
