Answer:
Oxidation Number of Phosphorous = + 6
Explanation:
According to Rules of Assigning Oxidation States;
i) The Oxidation State of Hydrogen atom in a compound is assigned as +1 except for Hydrides i.e. NaH and MgH₂ where it is assigned with -1.
ii) The Oxidation State of Oxygen in a compound is assigned as -2 except for Peroxides where it is given -1 and OF₂ where it is assigned with +1 respectively.
Oxidation State of P in H₂P₃O₁₀;
As over all molecule is neutral we can write it as,
H₂P₃O₁₀ = 0
Putting oxidation number of H and O,
(+1)₂ + P₃ + (-2)₁₀ = 0
(+2) + P₃ + (-20) = 0
+ 2 + (P)3 -20 = 0
(P)3 = + 20 - 2
(P)3 = + 18
P = + 18 ÷ 3
P = + 6
Yes it is right sir or ma’am
Answer:
The answer to your question is T2 = 319.4°K
Explanation:
Data
Volume 1 = V1 = 852 ml
Temperature 1 = T1 = 288°K
Volume 2 = V2 = 945 ml
Temperature 2 = T2 = ?
Process
To solve this problem, use Charles' law.
V1/T1 = V2/T2
-Solve for T2
T2 = V2T1/V1
-Substitution
T2 = (945 x 288) / 852
-Simplification
T2 = 272160 / 852
-Result
T2 = 319.4°K
Hi!
To convert grams to moles, you need to divide the amount (grams) of your substance by its molar mass, both of which are given to you.
28 g CaO / 58.08 g/mol CaO = 0.4820936639 moles of CaO
(And 28 contains two significant digits, so you will round this to 0.48 moles.)
Good luck!
