Answer:
2 moles CO2
Explanation:
According to the stoichiometric ratio the mole ratio of CaCO3:CO2 is 1:1
Therefore the moles of CO2 = 2 * (1/1)
= 2 mol CO2
Number of protons = 1
Electrons = 1
Neutrons = 0
[ Data of a neutral Hydrogen only ]

Answer: The correct answer is 'increases to 100 times the original concentration'.
Explanation:
let the initial pH be x
The original concentration of initially present be y
...(1)
Final concentration of when pH reduced by 2 be z
...(2)
Putting the value of 'x' from (1) into (2) we get :
When pH of a solution decreases by 2.0, hydronium ion concentration of the solution increases to 100 times the original concentration
Answer:
b
Explanation:
by using formula
a=(v-u)/t
where a= acceleration
v = initial velocity = 10 m/s
u= final velocity =50 m/s
t = time taken = 2s
<span>CHCl3 because there are more than two atoms in this molecule that are different. Hydrogen has a small electron cloud and occupies less space, where Cl has a larger electron cloud and occupies more space, this would make it different than the expected tetrahedron shape.</span>
