HSiCl3+H2O=H10Si10O15+HCl
tiny-mole [99]

10 HSiCl3+ 15 H2O→H10Si10O15+ 30 HCl

Explanation:

Step 1: To make Si equal on both sides. put 10 in front of HSiCl3

10 HSiCl3+ H2O →H10Si10O15+ HCl

Step 2: By putting 30 in front of HCl, Cl can be balanced

10 HSiCl3+ H2O →H10Si10O15+ 30 HCl

Step 3: Now, balance O by putting 15 in front of H2O

10 HSiCl3+ 15 H2O→H10Si10O15+ 30 HCl

Hence the balanced equation is:

10 HSiCl3+ 15 H2O→H10Si10O15+ 30 HCl

How much energy would be absorbed as heat by 75 g of iron when heated from 295 k to 301 k?
Katen [24]

Answer:

Q=202.5J

Explanation:

Hello,

In this case, the increase in the temperature involves the addition of heat that is defined in terms of mass, heat capacity and temperature:

Q=mCp(T_2-T_1)

In this case, the heat capacity of iron is 0.450 J/(g*K), thus the heat results:

Q=75g*0.450\frac{J}{g*K}*(301-295)K\\\\Q=202.5J

In such a way, since the temperature is increased heat is added, that is why it is positive.

Best regards.
