Answer:
The correct statement is option c, that is, particles discharged in the air by volcanoes fall to the ground and enrich the soil.
Explanation:
The eruptions of volcanoes lead to the dispersion of ash over the broader regions surrounding the site of eruption. On the basis of the chemistry of the magma, the ash will be comprising different concentrations of soil nutrients. While the major elements found in the magma are oxygen and silica, the eruptions also lead to the discharging of carbon dioxide, water, hydrogen sulfide, sulfur dioxide, and hydrogen chloride.
In supplementation, the eruptions also discharge bits of rocks like pyroxene, potolivine, amphibole, feldspar that are in turn enriched with magnesium, iron, and potassium. As an outcome, the areas which comprise huge deposits of the volcanic soil are quite fertile.
The number of moles of hydrogen atoms contained in 1 mole of c6h12 is 12.
<h3>What is hydrogen made of?</h3>
Hydrogen can be produced from various domestic resources such as fossil fuels, biomass, and the electrolysis of water by electricity. The environmental sustainability and energy efficiency of hydrogen depends on how hydrogen is produced.
Hydrogen is the simplest element. Each hydrogen atom has only one proton. Hydrogen is also the most abundant element in the universe. Stars like the Sun are mainly made of hydrogen. The sun is essentially a giant sphere of hydrogen and helium gas.
Some facts about hydrogen:
- Hydrogen is the most abundant element on earth.
- Hydrogen is an alternative fuel with a very high energy content by weight.
- The fuel cell can be used to power multiple applications.
- Fuel cells are a clean way to generate electricity.
Fuel cell vehicles are very similar to traditional gasoline vehicles

Answer:
Theoretical yield is 138.4 g
Explanation:
In the first step we determine the reaction:
3Mg + N₂ → Mg₃N₂
Mass of reactant is 100 g. We assume the nitrogen is in excess, so we work with Mg. We convert mass to moles:
100 g . 1mol/ 24.3g = 4.11 moles of Mg.
Ratio is 3:1. 3 moles of Mg can produce 1 mol of nitride
Our 4.11 moles, may produce (4.11 . 1)/3 = 1.37 moles of Mg₃N₂
We convert mass to moles, to find the theoretical yield:
1.37 mol . 100.9 g/mol = 138.2 g
Answer:
0.082 M
Explanation:
First we calculate the moles of KOH added, by multiplying its volume and concentration:
- 0.22 M * 16 mL = 3.52 mmol KOH
Given that <em>one mole of acid reacts with one mole of base</em>, in the lactic acid sample there were 3.52 acid moles as well.
Finally we divide the acid moles by the volume, to calculate the concentration:
- 3.52 acid moles / 43 mL = 0.082 M
