Answer:
The solubility of the salt is
46.75g salt/100g of H2O
Explanation:
If 7.70g of water can dissolve 3.60g at 21°C
That is 1.0g of water can dissolve (3.6÷7.7) grams of salt, that is 0.4675_g of salt at 21°C or 100 grams of water can dissolve 100×0.4675 = 46.75g
The solubility of the salt is
46.75g salt/100g of H2O
Answer:
A. Forming a positive ion!
Hope this helped :)
The ratio of reactant in grams would be influenced by the reaction equation and the molar mass of the elements. But the ratio of a reactant needed in grams would be same for a reaction.
If 2 grams of element X combine with 4 grams of element Y to form compound XY, it means the ratio of reactant in grams<span> would be 2:4 or 1:2
The number of element X needed for 28grams of element Y would be:
1/2 * 28grams = 14 grams.</span>
The question is incomplete, the complete question is:
Write the net ionic equation for the below chemical reaction:
(c): 
<u>Answer:</u> The net ionic equation is 
<u>Explanation:</u>
Net ionic equation is defined as the equations in which spectator ions are not included.
Spectator ions are the ones that are present equally on the reactant and product sides. They do not participate in the reaction.
(c):
The balanced molecular equation is:

The complete ionic equation follows:

As ammonium and chloride ions are present on both sides of the reaction. Thus, they are considered spectator ions.
The net ionic equation follows:

The answer is B) Miami, Florida.
