It’s Neon (Ne). You know because there are 10 protons and the number of protons is equal to the atomic number of an element. (Neon is #10 on the periodic table)
Answer:
make contact with the heat source
Explanation:
Answer:
Element name: Krypton
Symbol: Kr
Mass Number: 79 AMU
Charge: 0, electrons and protons cancel out.
ion: none, it is a halogen.
Explanation:
Krypton is the 36th element on the periodic table and has 36 protons. The mass is protons plus nuetrons so 36 + 43 is 79 AMU or Atomic Mass Units.

MnO₂(s) + 4 HCl(aq)→ MnCl₂(aq) + 2 H₂O(l) + Cl₂(g)
<u>Explanation:</u>
When aqueous solution of hydrochloric acid (HCl) reacts with solid Manganese(IV)oxide to form manganese(II)chloride in aqueous form, liquid water and then chlorine gas. The equation is given as,
MnO₂(s) + HCl(aq)→ MnCl₂(aq) + H₂O(l) + Cl₂(g)
It can be balanced by writing 2 in front of water and then writing 4 in front of HCl as,
MnO₂(s) + 4 HCl(aq)→ MnCl₂(aq) + 2 H₂O(l) + Cl₂(g)
So the balanced equation was found.
