Answer:
-184.6 KJ/mole
Explanation:
H2(g) + Cl2(g) ------------> 2HCl(aq)
Δ H0 rxn = Δ H0f products - Δ H0f reactants
= 2×-92.3 - (0 + 0)
= -184.6KJ/mole
H2(g) + Cl2(g) ------------> 2HCl(aq) Δ H0rxn = -184.6KJ/mole

Answer:
<h2>ATP, RNA, NAD and DNA.</h2>
Explanation:
A nitrogenous base; it is an organic molecule containing a nitrogen, carbon and other atoms that has the chemical properties of a base that is why they are called as bases. The nitrogenous bases are; i) adenine, ii) guanine, iii) thymine, iv) uracil and v)cytosine.
Adenine is a nitrogenous base which is found in ATP, RNA. NAD, FAD and DNA. adenine pairs with thymine in DNA synthesis.
Answer:209.53
Explanation:
Molar concentration=moles/Volume. Volume is given as 750mL which can be converted as 0.75l,so moles of CuBr2 is molar concentration ×Volume= 1.25×0.75=0.9375
Mole =mass of CuBr2/molecular Mass of CuBr2.
Molecular Mass of CuBr2 is 63.5+80×2=223.5(mass number of Cu=63.5 and Br=80).
So mass required= 223.5×0.9375=209.53g
In nuclear physics and nuclear chemistry, nuclear fission is either a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits<span> into smaller parts (lighter </span>nuclei<span>). Hope this helps</span>
