The Enthalpy of Reaction is the adjustment in the enthalpy of a compound response that happens at a consistent weight. It is a thermodynamic unit of estimation helpful for figuring the measure of vitality per mole either discharged or created in a response.
Answer:
Explanation:
An atom is the smallest indivisible particle that takes part in any chemical reaction. They are easily identified distinctively as elements in a compound.
The subscripts accompanying a chemical symbol shows the number of atoms of elements combining to give a compound:
Compound Elements Number of atoms
KBr K Br 2
C₁₂H₂₂O₁₁ 12(C) 22(H) 11(O) 12 + 22 + 11 = 45
KAlSi₃O₈ 1(K) 1(Al) 3(Si) 8(O) 1 + 1 + 3 + 8 = 13
Ag₃PO₄ 3(Ag) 1(P) 4(O) 3+ 1 + 4 = 8
CH₃CO₂C₆H₄COOH 9(C) 8(H) 4(C) 9+8+4 = 21
Answer:
you would need to multiply 50 times 2 wich is 100 so i beleive its 100
Explanation:
the final concentration of NaI solution in 60 grams/litre.
Explanation:
Given that:
Initial concentration of NaI solution M1 = 0.2 M
initial volume of NaI V1 = 2 L
Final volume V2 = 1 Litre
Final molarity=?
concentration in grams/litre = ?
molar mass of NaI = 150 gram/mole
For dilution following formula is used:
M1 V1 = M2V2
putting the values in the equation
0.2 X 2 = 1 X M2
M2 = 0.4
For concentration in grams/litre, formula used
molarity =
mass = 0.4 x 150
= 60 grams
So, 60 grams of NaI will be present in final solution of NaI after evaporation.
The concentration is 60 grams/ L (as volume got reduced to 1 litre from 2 litres)
There is a second nucleic acid in all cells called ribonucleic acid, or typically known as RNA. Like DNA, RNA is a polymer of nucleotides. Each of the nucleotides in RNA is made up of a nitrogenous base, a five-carbon sugar, and a phosphate group.
I really hope this helps, and I'm sorry if it doesn't It would be great if you posted the answer choices too.
