Answer:

C-solid, liquid, gas, plasma

Explanation:

Solid has strong forces of attraction between its bond so it need more time and energy to break it down compared to liquid and gas.

Gas is much faster than liquid since its particles are very very far apart.

‼️SHOW ALL STEPS‼️ If 14.4 grams of iron reacts with hydrochloric acid, how many grams of hydrogen gas will be produced?
Alex Ar [27]

Answer: 0.771 g of H_2 will be produced

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}    

\text{Moles of} Fe=\frac{14.4g}{56g/mol}=0.257moles

The balanced chemical reaction is:

2Fe(s)+6HCl(aq)\rightarrow 2FeCl_3(aq)+3H_2(g)  

According to stoichiometry :

2 moles of Fe produce = 3 moles of H_2

Thus 0.257 moles of Fe will produce=\frac{3}{2}\times 0.257=0.385moles  of H_2  

Mass of H_2=moles\times {\text {Molar mass}}=0.385moles\times 2g/mol=0.771g

Thus 0.771 g of H_2 will be produced

Answer:​

The solid sugar crystals break apart in water as the sugar dissolves, but the individual sugar particles or molecules are still present and do not change as a result of dissolving in the water. The combined mass of the sugar and water shouldn't change.
