There are 2 significant figures in this number. A significant figure is any number that isn’t 0. Hope this helps.
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>
In order to solve this type of problem, we take a look at the subscript of each element involved in the compound. These values signifies the number of particles present of that element in that compound. The calculation is as follows:
2.4 moles P2O10 ( 2 moles P / 1 moles P2O10 ) = 4.8 moles P
When a volcano erupts it releases a large amount of dust, smog, rock, and other materials. Basically, these bits and pieces float to form a metaphorical dust cloud. These clouds can often block out the sun like an ordinary cloud; however, because the cloud is dark, even less sun will be able to get through. So because the sun can't reach the ground, the temperature might decrease.
