Explanation:
Mitochondria (sing. mitochondria) are organelles, or parts of the eukaryote cell. They are in the cytoplasm, not the nucleus. They make the most cell supply of adenosine triphosphate (ATP), a molecule that cells use as an energy source. ... This means that mitochondria are known as '' the powerhouse of the cell'' or ''cell strength".
Good Luck, and have a great day..
Magnesium hydroxide react with hydrochloride to give magnesium chloride and water
THe word equation
magnesium hydroxide +hydrochroric acid---> Magnesium chloride+water
chemical equation
Mg(OH)2(S) + 2HCl (L)--> Mgcl2(S) + 2H2O(l)
when balancing the equation we count the number of molecules in the reactant side which should balance with molecules in the product side.
Answer:
ΔH = 41.7 kj
Given data:
Mass of ethanol = 50 g
Heat required to vaporize = ?
Boiling point of ethanol = 78.3°C
Molar heat of vaporization = 38.6 kj/mol
Solution:
First of all we will calculate the number of moles.
Number of moles = mass / molar mass
Number of moles = 50 g/ 46.07 g/mol
Number of moles = 1.08 mol
ΔH = 38.6 kj/mol ×1.08 mol
ΔH = 41.7 kj
