Answer:

Molecules

Explanation:

If you had more than one atom chemically bonded together, then regardless of the types of atoms that are bonded, you're going to have a molecule regardless.

Ava threw a hamster at her sister the other day she used 12N of force to accelerate the hamster at 8m/s2.what was the mass of th

xenn [34]

We are given:

The force applied on the poor hamster (F) = 12 N

Acceleration of the poor Hamster (a) = 8 m/s²

Solving for the mass of the Poor Hamster:

From newton's second equation of motion, we know that:

F = ma

replacing the given values

12 = 8 * m

m = 12/8 kg

m = 3/2 kg

The poor Hamster weighs 3/2 kg

Two steps in a synthesis of the analgesic ibuprofen include a carbonyl condensation reaction, followed by an alkylation reaction

Tresset [83]

Ibuprofen is synthesized by reacting ethyl 2-(4-isobutylphenyl)acetate with base, the base abstracts the acidic proton and enolate is formed which on reaction with diethyl carbonate generates diethyl 2-(4-isobutylphenyl)malonate (A). diethyl 2-(4-isobutylphenyl)malonate on treatment with Base again looses the acidic proton and forms enolate. The enolate with treatment with Methyl Iodide yields diethyl 2-(4-isobutylphenyl)-2-methylmalonate (B). diethyl 2-(4-isobutylphenyl)-2-methylmalonate on hydrolysis give Ibuprofen.

How many kJ of heat are needed to completely melt 17.3 g of H2O, given that the water is at its melting point? The heat of fusio

zzz [600]

Answer: Heat required for 17.3 g of water to completely melt will be 5.785 kJ.

Explanation: Heat of fusion is defined as the amount of heat require to change the state from solid to liquid for 1 mole of solid at its melting point. It is expressed as $\Delta H_{fusion}$

We are given 17.3 grams of water. So, to convert it into moles, we use the formula:

$Moles=\frac{\text{Given mass}}{\text{molar mass}}$

Molar mass of water = 18g/mol

Putting values in above equation, we get:

$Moles=\frac{17.3g}{18g/mol}$

Moles of water = 0.961 moles

For 1 mole of water, heat of fusion is 6.02kJ/mol

So, for 0.961 moles of water, heat of fusion will be = (0.961 moles × 6.02 kJ/mol) = 5.785 kJ
