T = 2T , P = 2P as given in the question

Volume = mass *density

Now apply ideal gas law

PV=nRT

V = nRT/P

substitute value of V and P

V = nR2T/2P

V =nRT/P

mass*density = nRT/P

density will not change

You titrate 5.0 mL of HCl with 0.010 M NaOH. You find the end point of your titration occurs when 12.0 mL of NaOH has been added
leonid [27]

Answer:

The total volume of the solution at the end point of the titration is 17.0 mL

Explanation:

First we will write a balanced chemical equation for the reaction between HCl and NaOH.

HCl + NaOH    →    NaCl + H₂O

This means 1 mole of HCl will react with 1 mole of NaOH to give 1 mole of NaCl and 1 mole of H₂O

From the question,

Concentration of acid (HCl), C_{A} = ??

Volume of acid (HCl), V_{A} = 5.0 mL

Concentration pf base (NaOH), C_{B} = 0.010 M

Volume of base (NaOH), V_{B} = 12.0 mL

To determine the Concentration of acid, C_{A}

From,

\frac{C_{A}V_{A}  }{C_{B}V_{B}  } = \frac{n_{A} }{n_{B} }

Where n_{A} is the mole ratio of acid

and n_{B} is the mole ratio of base.

The concentration of the acid used can be determined from the above formula.

But, we are asked to find the total volume of the solution at the end point of the titration

The total volume of the solution will be the sum of the volume of HCl that reacted and volume of NaOH that reacted.

Hence, The total volume of the solution = V_{A} + V_{B}

= 5.0 mL + 12.0 mL

= 17.0 mL

Hence, the total volume of the solution at the end point of the titration is 17.0 mL

Does acid rain make new substances?
ivanzaharov [21]

Answer:

Over the past few decades, humans have released so many different chemicals into the air that they have changed the mix of gases in the atmosphere. ... In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air.

Both sound waves and light waves are?
Ierofanga [76]

Answer:

Sound and light are similar in that both are forms of energy that travel in waves. They both have properties of wavelength, freqency and amplitude. Here are some differences: Sound can only travel through a medium (substance) while light can travel through empty space.

Which of the quantum numbers relate(s) to the electron only? Which relate(s) to the orbital?
olganol [36]

Answer:

Schrodinger's proposal, considered as the 5th atomic model, is to describe the characteristics of all the electrons in an atom, and for this I use what we know as quantum numbers.

Quantum numbers are called with the letters n, m, l and s and indicate the position and energy of the electron. No electron of the same atom can have the same quantum numbers.

Explanation:

n = main quantum number, which indicates the level of energy where the electron is, assumes positive integer values, from 1 to 7 and it is related to the orbital too.

I = secondary quantum number, which indicates the orbital in which the electron is located, can be s, p, d and f (0, 1, 2 and 3).

m = magnetic quantum number, represents the orientation of the orbitals in space, or the type of orbital, within a specific orbital. Assumes values ​​of the negative secondary quantum number (-l) through zero, to the positive quantum number (+ l).

s = quantum number of spin, which describes the orientation of the electron spin. This number takes into account the rotation of the electron around its own axis as it moves around the nucleus. Assumes only two values ​​+1/2 and - 1/2
