A chemist performs the same tests on two homogeneous white crystalline solids, A and B. The results are shown in the table below

. Solid A Solid B Appearance and Texture Crystalline Crystalling and Powdery Solubility in Water g per 100 mL H2O at 0 0C 35.7 10.5 Conductivity (Yes/No) Good Conductor Okay Conductor The results of these test suggest that: both solids only contain ionic bonds both solids only contain Covalent bonds Solid A contains only Ionic bonds and solid B only contains Covalent bonds Solid A contains only Covalent bonds and solid B contains only Ionic bonds One Solid contains only one type of bond and the other contains both types of bonds Defend your answer:

Solid A contains only Covalent bonds and solid B only contains Ionic bonds. I know this because the appearance, solubility, and conductivity of solid A describes Covalent bonds.

Explanation:

Try this, but idk if it will be marked as correct.

In a coffee shop, the following coffee samples are prepared for customers. i. 10 g of sugar added to 100 g of coffee ii. 10 g of
dem82 [27]

So solve this we must know the amount of sugar per gram of coffee

<span>i.              </span>10 g sugar /100 g coffee = 0.1 g sugar/ 1 g coffee

<span>ii.            </span>10 g sugar / 200 g coffee = 0.05 g sugar / 1 g coffee

<span>iii.           </span>4 g sugar / 200 g coffee = 0.02 g sugar / 1 g coffee

<span>iv.           </span>4 g sugar / 100 g coffee = 0.04 g sugar / 1 g coffee

 

So the ranking from sweetest so the least is:

<span> i, ii, iv, iii</span>

Acetone major species present when dissolved in water
jek_recluse [69]

Answer: acetone molecule ( CH₃-CO-CH₃)


Explanation:


1) Acetone is CH₃-CO-CH₃


2) That is a molecule (build up of covalent bonds).


3) When dissolved, covalent bonded compounds remain as separate molecules, then it is said that the major species present in the solution is the molecule. The molecules of acetone are surrounded (sovated) by the molecules of water.


This as opposed to the case of ionic compounds that ionize. When a compound as NaCl dissolves in water, it ionizes completely, so the major speceies are not NaCl formulas, but the ions Na⁺ and Cl⁻, not molecules.


That leads to the answer: the major species present when acetone is dissolved in water is the molecules of acetone (you do not need to state the fact that the molecules of water are part of the solution, because that is not the target of the question).
