A. x Ray's have the second highest frequency in the light spectrum after gamma rays
Answer:
a. Lack of OH group on 2′ carbon of the deoxyribose
electrons are arranged in shells around an atom's nucleus. Electrons closest to the nucleus will have the lowest energy.
Barium peroxide is BaO2.
Hydrogen peroxide is H2O2
This reaction produces hydrogen peroxide from barium peroxide:
BaO2 + H2SO4 ---> BaSO4 + H2O2
So, 1 mol of BaO2 produces 1 mol of H2O2.
Convert 1.50 g of BaO2 to moles:
moles = mass in grams / molar mass
molar mass of BaO2 = 137g/mol + 2*16g/mol = 169 g/mol
moles of BaO2 = 1.50g / 169 g/mol = 0.00888 moles
Then, the same number, 0.00888, will be produced of H2O2.
Now convert 0.00888 moles of H2O2 to mass in grams:
mass in grams = number of moles * molar mass
molar mass of H2O2 = 2 * 1 g/mol + 2 * 16 g/mol = 34 g/mol
mass of H2O2 = 0.00888 moles * 34 g/mol = 0.30192 grams.
Rounded to 3 significant figures = 0.302 grams.
Answer: 0.302 grams
The equation of the reaction is;
Ca(OH)2(aq) + 2HCl(aq) ------> CaCl2(aq) + 2H2O(l)
<h3>What is neutralization?</h3>
The term neutralization has to do with the process in which an acid reacts with a base to form salt and water only. A neutralization reaction is known by the fact that water is obtained by the reaction of hydrogen and hydroxide ions.
