Sucrose is more soluble in water. The reason can be attributed to hydrogen bonding between water molecules and sucrose molecules.

Answer:

Sucrose.

Explanation:

Hello,

On the attached pictures you will find the structural formulas for both lauric acid and sucrose respectively. In this manner, since the sucrose has more OH bonds promoting the formation of hydrogen bond-like intermolecular forces with water, it will be more soluble in water than lauric acid, since it just has a remote carboxyle functional group which is not enough to provide solubility in water.

Best regards.

What does the name iron(ii) in a compound indicate about the cation?

bija089 [108]

Answer:- $Fe^+^2$

Explanations:- Transition elements shows variable oxidation states. So, while naming these compounds we use the roman numerals to tell their oxidation states.

For example, if someone writes just Iron oxide then it would not be correct since Iron could be in +2 or +3 states. So, it might be $Fe^+^2$ or $Fe^+^3$ . So, the right was is to mention the oxidation state of the transition metal.

If the name is written as Iron(II) in a compound then it means there is +2 charge on iron and it is $Fe^+^2$ .

Which is the safest method for diluting concentrated sulfuric acid with water?

Anton [14]

The safest method for diluting concentrated sulfuric acid with water is to add acid to water. This way, when spill occurs, the acid is already diluted and less harmful than adding water to acid.

Answer:

2 moles of Sn are produced when 4 moles of H2(g) are consumed completely

Explanation:

to determine the number of moles of sn (l) produced when 4.0 moles of H2 (g) is consumed completely.

First, find the number of moles of H2 consumed by taking this as limiting reagent.

$n = \frac{g}{M.W (g/mol)}$

Then find the moles of Sn (l) taking into account the stoichiometric relationship between H2(g) and Sn(l). 2:1

$SnO_{2}$ (s) + 2 $H_{2}$ (g) ⇒ Sn(l) + 2 $H_{2}O$ (g)

$mol Sn(l) = \frac{1mol Sn}{2mol H_{2} } . 4 mol H_{2} = 2 mol$

∴2 moles of Sn are produced when 4 moles of H2(g) are consumed completely.

HEY DEAR..

PHYSICAL CHANGE

Those Changes in which no new substances are formed are called physical changes. it is a temporary changes which can be reversed easily to form the original substance.

Example:- Melting of ice , Making a solution, Glowing of an electric bulb , freezing of water etc.

CHEMICAL CHANGE

Those changes in which new substances are formed are called chemical changes. it means it is permanent changes which are usually irreversible.

Example:- Burning of charcoal, fuels and cutting of trees, even digestion of food is in chemical change.
