Answer:
2, the acid is H₂X.
Explanation:
- It is known at equivalence point: the no. of millimoles of base is equal to the no. of millimoles of acid.
<em>∴ (nMV) of NaOH = (nMV) for HnX.</em>
where, n is the no. of producible H⁺ or OH⁻ of the acid or base, respectively.
M is the molarity of the acid or base.
V is the volume of the acid or base.
n = 1, M = 0.4 M, V = 0.6 L.
n = ???, M = 0.3 M, V = 0.4 L.
∴ n for HnX = (nMV) of NaOH / (MV) for HnX = (1)(0.4 M)(0.6 L)/(0.3 M)(0.4 L) = 2.
∴ the acid is H₂X.
Answer:
=3 means is 3 or greater so that would be f and g subshells
=0 means is 0 or greater so that would be s, p, d, f and g subshells
=1 means is 1 or greater so that would be p, d, f, and g subshells
=4 means is 4 or greater so that would be g only
Explanation:
when hot copper metal reacts with chlorine gas it forms CuCl2 which is yellow in colour.
non metal carbon burns in Oxygen gas they form non metal oxide.
yes substances Do react by mass
