What's the amount of solute in 1.75 L of 0.25 M HCl?
Fynjy0 [20]

Answer: 0.4375 mols of solute

Explanation:

The problem is asking for the amount of solute. We are given the value of molarity. The molarity is 0.25M. We know that molarity is M=\frac{mols of solute}{liters of solution}. Since we are given the liters of solution is 1.75, we can use those values to solve for mols of solute.

0.25M=\frac{x}{1.75L}                        [multiply both sides by 1.75 L]

x=0.4375 mols

There are 0.4375 mols of solute.

Answer:

(a).

order \: of \: A = 2 \\ order \: of \:B  = 0 \\ rate = k[A] {}^{2} [B]

(b)

0.32 \times  {10}^{ - 3}  = k {(0.12)}^{2} (0.15) \\ k = 0.148 \:  {mol}^{ - 2}  {dm}^{6}  {s}^{ - 1}

(c). The rate increases because kinetic energy of reactant molecules increases.

A student states that this structural formula represents a hydrocarbon.
DedPeter [7]
Answer: <span>Yes, a hydrocarbon is any compound that contains hydrogen and oxygen.

Justification:

First, I will try to rewrite the given structural formula since it is misrepresented.

This should be the right structural formula:

       H    H
       |      |
H - C  -  C - OH
       |      |
      H     H

And, yes the definition of hydrocarbon is that it is most simple organic compound constitured only by atoms of carbon (C) and hydrogen (H).

By the way, that hydrocarbon is also represented as CH3 - CH2 OH, it is an alcohol (since it has the functional group OH) and its name is ethanol.
