Al2(SO4)3 + 3CaCl2 > 2AlCl3 + 3CaSO4
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
<u>Importance </u><u>of </u><u>Circulatory </u><u>System</u>
- This system helps in transportation of respiratory gases like O2 and CO2, nutrients, hormones, enzymes, minerals, waste products.
- It helps in storage of essential substances for future use.
- It also generates heat to the body.

Answer:

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:

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

In such a way, since the temperature is increased heat is added, that is why it is positive.
Best regards.
<span>The temperature change is greater when assuming that the mass is constant and the heat must be greater </span>in the result the heat of the metal as being reported too high.
hope it helps
