Answer:
124.98
Explanation:
The molar mass of phosphorus, M=PVwRT=1×34.05×10−30.0625×0.08314×819=124.98.
Answer:
Gravitational energy and thermal energy
Explanation:
A water cycle is a product of gravitational energy from the earth and thermal energy from the sun.
A water cycle is driven around with the help of hydroelectric energy. Now hydroelectric energy is a product of potential energy that is converted into kinetic energy, with the help of gravitational energy, which again is also acquired from thermal energy from the sun.
Therefore, the correct answer is gravitational energy and thermal energy.
<span>Ammonia, NH. Hydrogen atoms can each form one covalent bond, while and nitrogen atoms can each form three covalent bonds. Three pairs of electrons are shared in an ammonia molecule (NH3).</span>
According to this formula:
Q = M*C*ΔT
when we have M ( the mass of water) = 200 g
and C ( specific heat capacity ) of water = 4.18 J/gC
ΔT (the difference in temperature) = Tf - Ti
= 100 - 24
= 76°C
So by substitution:
Q = 200 g * 4.18 J/gC * 76 °C
= 63536 J
∴ the amount of heat which be added and absorbed to raise the temp from 24°C to 100°C is = 63536 J
Answer:
Sodium bicarbonate.
Explanation:
The gas produced during the mixing of bath bombs in water is Sodium bicarbonate. If the reaction is with citric acid then Sodium citrate can be produced. They are weak acid with bicarbonate base. These bath bombs can be a mixture of wet and dry substances and any shape can be mold.
