How many moles of SnF₂ will be produced along with 48 grams of H₂? *
Oxana [17]

Answer:

The correct option is;

24 moles

Explanation:

Here, we have the reaction as follows;

Sn(s) + 2HF(g) → SnF₂ (s) + H₂ (g)

Therefore, one mole of Sn reacts with 2 moles HF to form one mole of SnF₂ and one mole of H₂

Molar mass of H₂ = 2.01588 g/mol

Therefore, the number of moles of H₂ in 48 grams of H₂ is given by the relation;

Number \ of  \ moles \ of \, H_2 = \frac{Mass \ of  H_2}{Molar \ Mass \ of  H_2}=\frac{48}{2.01588} = 23.8109 \ moles \approx 24 \ moles

Since one mole each of SnF₂ and H₂ are produced, the number of moles of SnF₂ produced = 24 moles.

The number of moles of SnF₂ that will be produced is 24 moles.

Why is atp an example of chemical potential energy?
marta [7]
Hello! I hope this helps

Answer: ATP ( adenosine triphosphate) is considered as the energy currency of the cell as it stores energy in the cell. It is an example of chemical potential energy because energy is stored in the high energy containing phosphoanhydride bond (between phosphate molecules in the ATP).

60g ethane requires 7x32= 224g oxygen

here ethane is in excess.oxygen will be fully consumed

hence

300g oxygen will consume

224

=

80.36

g

ethane

leaving (270-80.36)= 189.64 g ethane.

By the Balanced eqn

60g ethane produces 4x44 g CO2

hence amount of CO2 produced =
