Answer:
A) MgCO₃ is insoluble
Explanation:
Based on the rules of solubility:
All nitrates are soluble. That means Pb(NO₃)₂ is soluble.
All ammonium ions are soluble. NH₄Br is soluble.
All phosphate are insoluble except when combined with group I ions (Li, Na, K...) K₃PO₄ is soluble.
Also, all carbonates are insoluble except when combined with group I ions. That means Li₂CO₃ is soluble and:
<h3>A) MgCO₃ is insoluble</h3>
Business owners must consider the products mission statement, a unique brand, the timing, the packaging, promotion, the audience.
To create a product you first need a problem then a solution. So if the problem is that water bottles aren’t holding enough water, the solution would be to create bigger yet lighter water bottles.
Let’s say you are to create a water bottle that is sturdier than others and can hold more water but weigh less. You would first consider the target audience. People that exercise and are into fitness would find the product more useful. So many making changes to the product to better fit their needs will help. Next the promotion and timing . It would be best to release the product near New Years since that’s when most people go to gyms. This will allow your product to reach a greater target audience and have more sales. Also testing your bottle to make sure it’s up to what you’re proving and so on.
In amides, the carbonyl carbon is bonded to a nitrogen. The nitrogen in an amide can be bonded either to hydrogens, to carbons, or to both. ... Another way of thinking of an ester is that it is a carbonyl bonded to an alcohol. Thioesters are similar to esters, except a sulfur is in place of the oxygen.
A measure of peak separation in a chromatographic method that equals the difference in retention time for two components divided by the average of their peak widths is the definition of resolution.
Retention time can be referred to as the amount of time a solute spends in the stationary and mobile phases of a column.
The analyte's interaction with the stationary phase determines the longer retention period.
The duration of retention will increase as the interaction becomes more strong.
Resolution is defined as the peak separation in a chromatographic procedure that is equal to the difference in retention time for two components divided by the average of their peak widths.

C. Neon is the element which is not likely to form bonds. This is because neon is a noble gas, which means that it already has the maximum of 8 valence electrons, and doesn't need more, whereas gold, oxygen, and mercury can bond more electrons.
