Answer:

C. A neutron turns into a proton

D. An electron is ejected from the nucleus

Explanation:

  • Beta decay is a type of the three major types of decays, others being alpha decay and gamma decay.
  • During a beta decay the atomic number of an atom increases by one while the mass number remains the same.
  • Beta decay may be classified as; an electron emission, positron emission and electron capture.
  • <em><u>During electron emission an energetic electron is emitted from the nucleus, together with an antineutrino and a neutron in the nucleus turns into a proton. </u></em>

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

What happens when you heat a sugar and water mixture?
a_sh-v [17]
Sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. When water is heated, the molecules gain energy and, thus, move faster. As they move faster, they come into contact with the sugar more often, causing it to dissolve faster.
