Answer:Ionic compounds are compounds composed of ions, charged particles that form when an atom (or group of atoms) gains or loses electrons. (A cation is a positively charged ion; an anion is a negatively charged ion.) Covalent or molecular compounds form when elements share electrons in a covalent bond to form molecules.
Answer:
The mole ratio of the cation and the anion in a precipitate is a simple fraction. ( im sorry if this dosent help a lot.)
Explanation:
Speed is equivalent to the distance traveled divided by the time it takes to travel that certain distance.
To solve this problem convert the units first from meter and yards to miles. 100 metes is 0.0621371mi and 100 yards is 0.0568182 yard. 9.69s = 0.002691667 hr and 9.21s = 0.002558333
A.) 23mi/hr
B.) 22.20mi/hr
Ra(s) + H₂O(g) → Ra(OH)₂ (aq) + H₂ (g)
<u>Explanation:</u>
Radioactive radium reacts easily with water produces radium hydroxide and hydrogen gas. In this reaction, Radium is sin solid state reacts with the water in the gaseous state to produces aqueous radium hydroxide and the hydrogen gas. This reaction occurs rapidly than in Barium. We can write this reaction as,
Radium(s) + water(g) → Radium hydroxide (aq) + Hydrogen (gas)
This can be represented using the symbols as,
Ra(s) + H₂O(g) → Ra(OH)₂ (aq) + H₂ (g)
Thus the above process can be expressed with such chemical reaction.
