Answer:

10.08 L.

Explanation:

If we assume that CO₂ gas behaves ideally at STP (standard T(0.0 °C) and P(1.0 atm)):

It is known that 1.0 mole of ideal gas occupies 22.4 L at STP conditions.

Using cross multiplication:

1.0 mole of CO₂ gas occupies → 22.4 L.

0.45 mole of CO₂ gas occupies → ??? L.

∴ The volume occupied by 0.45 mole of CO₂ gas = (0.45 mol)(22.4 L)/(1.0 mol) = 10.08 L.

When a catalyst is added to a reversible reaction in equilibrium state the value of equilibrium constant

Sergio [31]

Explanation:

The value of equilibrium constant doesn't change when a catalyst is added.

Equilibrium constant depends on Concentration of reactants , Pressure and Temperature.

What causes water to increase in density?

murzikaleks [220]

Explanation:

temperature changes affect seawater density as water cools its density increases. As water cools H2O molecules pack more closely together because the molecules are vibrating less at low temperatures and take up less volume. The same number of water molecules in smaller volume results higher density

Which pair of reactants will undergo aldol condensation to produce methylvinyl ketone?

xenn [34]

When formaldehyde and acetone then react with each other( aldol condensation) then it will be formed methyl vinyl ketone.

In organic chemistry, an aldol condensation would be a condensation reaction in which an enol and enolate ion combines with a carbonyl chemical to produce a -hydroxy aldehyde or -hydroxy ketone, that is then dehydrated to produce a conjugated enone.

In aldol condensation, when formaldehyde and acetone then react with each other then it will be formed methyl vinyl ketone.

It can be written as

$CH_{2} O + CH_{3} COCH_{3}$ → $HOCH_{2} -CH_{2} -CO-CH_{3}$

When it will be heated then it gives methyl vinyl ketones.

$HOCH_{2} -CH_{2} -CO-CH_{3}$ → $CH_{2} =CH-CO-CH_{3}$

So, the pair of reactants will be formaldehyde and acetone

A scientist is studying a previously unknown chemical reaction. She concludes that it is exothermic. What must the scientist hav

SVEN [57.7K]

I think the correct answer from the choices listed above is the first option. She concluded that the reaction is an exothermic one because the reaction released heat. Exothermic is when heat goes out of the system. The opposite is referred to as an endothermic reaction.
