Answer:
Carbon atoms can form double bonds by sharing two pairs of electrons; they can also form triple bonds by sharing three pairs of electrons.
I believe the correct answer from the choices listed above is option A. The statement that best describes the use of chemical indicator in a titration would be that it measures the quantity of acid dissolved in water designated by molarity. <span>A </span>titration<span> is a method of analysis that will allow you to determine the precise endpoint of a reaction .</span>
<span>The rate of crystallizing is equivalent to the rate of dissolving.</span>
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
