Answer:

The correct answer is - solute.

Explanation:

A solute is one half of a solution that is dissolved in the other half of the solution, known as the solvent. Solute particles are always less or lower in quantity or concentration than the solvent in a solution.

In this case, coffee crystals are dissolved in hot water so the solute will be coffee crystals and the amount of coffee crystals are also less than the amount of solvent.

2. The diagram below shows steps in the exothermic chemical reaction of bromomethane with
vovangra [49]

Answer:

Here's what I get  

Explanation:

1. Balanced equation

HQ⁻ + CH₃-Br ⟶ HQ-CH₃ + Br⁻

(I must use HQ because the Brainly Editor thinks the O makes a forbidden word)

2. Mechanism

HQ⁻ + CH₃-Br ⟶[HQ···CH₃···Br]⁻⟶ HQ-CH₃ + Br⁻

        A                           C                         B

The hydroxide ion attacks the back side of the carbon atom in the bromomethane (A).

At the same time as the Q-H bond starts to form, the C-Br bond starts to break.

At the half-way point, we have a high-energy intermediate (C) with partially formed C-O and C-Br bonds.

As the reaction proceeds further, the Br atom drops off to form the products — methanol and bromide ion (B).

How many hydrogen atoms are in 8.80 mol of ammonium sulfide
vladimir1956 [14]
Assuming that the ammonium sulfide formula is (NH4)2S then you can see that there are 2 nitrogen, 8 hydrogen and 2 sulfur atoms for every ammonium sulfide. If the amount of ammonium sulfide is 8.9 moles, then the number of hydrogen atoms should be: 8/1 * 8.9 mol= 71.2 moles

What is the temperature of 4.5 moles of a gas that occupies 50. mL at 1.35 atm?
devlian [24]

Answer:

T = 0.182 Kelvin

Explanation:

As we know that

PV = nRT\\

Where P is the pressure in atmospheric pressure

T is the temperature in Kelvin  

R is the gas constant  

V is the volume in liters

R = 0.08206

Substituting the given values in above equation, we get -

1.35 * \frac{50}{1000}= 4.5 * 0.08206* T\\

On rearranging, we get

T = \frac{1.35*50}{1000*0.08206*4.5} \\

T = 0.182 Kelvin
