I thought long and hard about it and i would say C) is the right answer
A redox reaction occurs
<h3>Further explanation</h3>
Given
Reaction
Ca(ClO3)2 → CaCl2 + 3O2
Required
Type of reaction
Solution
The reaction equation is said to be a redox reaction if there is an oxidation reaction (increase in oxidation number) and a reduction reaction (decrease in oxidation number)
Oxidation number of Cl in Ca(ClO3)2 :+5
Oxidation number of Cl in CaCl2 = -1
Reduction : +5 to -1
O in Ca(ClO3)2 : -2
O in O2 : 0
Oxidation : -2 to 0
So there is a reduction and oxidation reaction
Answer:
1 mole
Explanation:
Data obtained from the question include:
P (pressure) = 750 torr
But 760torr = 1atm
750 torr = 750/760 = 0.99atm
V (volume) = 25L
T (temperature) = 300K
R (gas constant) = 0.082atm.L/Kmol
n (number of mole) =?
Using the ideal gas equation PV = nRT, we can easily find the number of mole as illustrated below:
PV = nRT
n = PV /RT
n = 0.99 x 25 / 0.082 x 300k
n = 1 mole
Therefore, the number of mole of the gas is 1 mole
QUICK ANSWER
Electrons have a relative mass of 9.1 x 10^-31 kilograms, or 0.51 megaelectron volts. They are a lot smaller than protons and neutrons; and, an electron is roughly 0.054 percent of the mass of one neutron.
