Two substances, A and B, initially at different temperatures, come into contact and reach thermal equilibrium. The mass of subst

ance A is 6.27 g and its initial temperature is 20.9 ∘C . The mass of substance B is 26.1 g and its initial temperature is 52.7 ∘C. The final temperature of both substances at thermal equilibrium is 46.3 ∘C.
If the specific heat capacity of substance B is 1.17 J/(g⋅∘C), what is the specific heat capacity of substance A?

4 b + 3 o2 → 2 b2o3 if 8 moles of b and 4 moles of o2 are allowed to react, how many moles of b2o3 can be formed?
raketka [301]

The number of moles of  b2o3 that will be formed is determined as 4 moles.

<h3>Limiting reagent</h3>

The limiting reagent is the reactant that will be completely used up.

4 b + 3O₂ → 2b₂O₃

from the equation above;

4 b ------------> 2 b₂O₃

2b ------------> b₂O₃

2 : 1

3O₂  -------------> 2b₂O₃

3  :  2

b is the limiting reagent, thus, the amount of b2o3 to be formed is calculated as;

4 b ------------> 2 moles of  b2o3

8 moles -------> ?

= (8 x 2)/4

= 4 moles

Thus, the number of moles of  b2o3 that will be formed is determined as 4 moles.
