when 2 average is 1 and 1 average is0.5
Answer:
The correct answer is sedimentary rock.
Explanation:
The sedimentary rocks are the types of rocks, which are produced due to the deposition and the succeeding cementation of that substance at the shallow part of the Earth and within the water bodies. In the geological sciences, sedimentation refers to the procedure of the deposition of the solid substance from a state of solution or suspension in a fluid, that is, water or air.
In order to compute the total hydrogen atoms present, we must first write the molecular formulas of ammonia and water to know how many hydrogen atoms are present in each molecule.
Water - H₂O; so 2 hydrogen atoms per molecule of water
Ammonia - NH₃; so 3 hydrogen atoms per molecule of ammonia
Total hydrogen atoms = 2 * molecules of water + 3 * molecules of ammonia
H atoms = 2 * 1.5 x 10²⁵ + 3 * 8.2 x 10²⁴
H atoms = 5.46 x 10²⁵
There are a total of 5.46 x 10²⁵ hydrogen atoms in the solution
Answer:
107,200J or 25.62 kcal
Explanation:
The latent heat of water is 4.2J/g °C so the energy needed to increase the tempearture from 80 °C to 100°C will be:
40g * 4.2J/g °C * (100-80°C )= 3,360J
The heat of vaporization of water is 2260J/g so the energy need to change water from liquid to gas is:
40g * 2260J/g = 90,400J
The heat needed to increase steam temperature should be same as latent heat of water, 4.2J/g °C . So, the energy needed to increase temeprature from 100 to 180 will be:
40g * 4.2J/g °C * (180-100°C )= 13,440J
The total energy needed will be: 3,360J + 90,400J +13,440J= 107,200J
