<span>Most atoms have three different subatomic particles insidethem: protons, neutrons, and electrons. The protons and neutrons are packed together into the center of the atom(which is called the nucleus) and the electrons, which are very much smaller, whizz around the outside.</span>Mar 9, 2017

If you add 14.22ml of 2.97m hcl (42.2mmol) to an antacid, then neutralize the excess acid with 5.00ml of 0.1055 m naoh (0.528mmo
Vinvika [58]

Given data:

Volume of HCl = 14.22 ml

Molarity of HCl = 2.97 M

mmoles of HCl = 14.22 * 2.97 = 42.2 mmoles

Volume of NaOH = 5.00 ml

Molarity of NaOH = 0.1055 M

mmoles of NaOH = 5.00 *.1055 = 0.5275 mmoles

Since HCl and NaOH combine in a 1:1 ratio

# moles of NaOH = # moles of excess HCl that is neutralized = 0.5275 moles

Now, the total moles of HCl taken = # mmoles HCl neutralized by antacid + # mmoles of excess HCl

42.2 = mmoles HCl neutralized by antacid + 0.5275

Therefore,

mmoles of HCl neutralized by antacid = 42.2 - 0.5275 = 41.6725 mmoles = 41.7 mmoles

Which of these statements describes this mathematical equation?
salantis [7]

Answer:

The final pressure of a gas is inversely proportional to the volume change and directly proportional to temperature

Explanation:

Given

\frac{P_1V_1}{T_1} = k

Required

Interpret

\frac{P_1V_1}{T_1} = k

Multiply both sides by T1

T_1 * \frac{P_1V_1}{T_1} = k * T_1

P_1V_1 = kT_1

Divide both sides by V1

\frac{P_1V_1}{V_1} = \frac{kT_1}{V_1}

P_1 = \frac{kT_1}{V_1}

This can be rewritten as:

P_1 = k\frac{T_1}{V_1}

In the above expression; k is a constant of proportionality.

So, the equation can be written as variation as follows:

P_1\ \alpha\ \ \frac{T_1}{V_1}

To interpret:

<em>P varies directly to T (the numerator) and inversely to V (the denominator).</em>
