Answer:
to change an atom labeled + ion or -ion into a neutral atom, an electron is either added or removed from it
Packets of energy called gamma particles
Answer:
C
Explanation:
others are boring or gems
Answer:
A star begins its life as a cloud of dust and gas (mainly hydrogen) known as a nebula. A protostar is formed when gravity causes the dust and gas of a nebula to clump together in a process called accretion. ... If a critical temperature in the core of a protostar is reached, then nuclear fusion begins and a star is born.
Explanation:
.
Potassium carbonate, K2CO3, sodium iodide, NaI, potassium bromide, KBr, methanol, CH3OH, and ammonium chloride, NH4Cl, are solub
just olya [345]
Answer:
A. K₂CO₃
Explanation:
The chemical reaction showing the ions produced on dissolving Potassium carbonate in water is:
K₂CO₃ ⇒ 2K⁺ + CO₃²⁻
Number of ions produced = 2 + 1 = 3
The chemical reaction showing the ions produced on dissolving sodium iodide in water is:
NaI ⇒ Na⁺ + I⁻
Number of ions produced = 1 + 1 = 2
The chemical reaction showing the ions produced on dissolving potassium bromide in water is:
KBr ⇒ K⁺ + Br⁻
Number of ions produced = 1 + 1 = 2
The chemical reaction showing the ions produced on dissolving ammonium chloride in water is:
NH₄Cl ⇒ NH₄⁺ + Cl⁻
Number of ions produced = 1 + 1 = 2
<u>The largest number of dissolved particles per mole of dissolved solute is produced by Potassium carbonate.</u>
