20 ML of a gas at 200 K is heated until the new volume is 55ML what is the final temperature of the gas
MrRa [10]

Answer:

T2 = 550K

Explanation:

From Charles law;

V1/T1 = V2/T2

Where;

V1 is initial volume

V2 is final volume

T1 is initial temperature

T2 is final temperature

We are given;

V1 = 20 mL

V2 = 55 mL

T1 = 200 K

Thus from V1/T1 = V2/T2, making T2 the subject;

T2 = (V2 × T1)/V1

T2 = (55 × 200)/20

T2 = 550K

PLEASE HELP!!!<br><br> What is the mass of one lead atom in amu?
alexandr402 [8]

Answer: 207.2

Explanation:

In imprecise terms, one AMU is the average of the proton rest mass and the neutron rest mass. This is approximately 1.67377 x 10 -27 kilogram (kg), or 1.67377 x 10 -24 gram (g). The mass of an atom in AMU is roughly equal to the sum of the number of protons and neutrons in the nucleus.

A cleaning solution has a hydroxide ion concentration of 2.5 x 104 mol/L. Which of the following
devlian [24]

A cleaning solution with an OH⁻ concentration of 2.5 × 10⁻⁴ mol/L, has a pH of 10.4 and is basic (options b and c).

<h3>How can we determine the acidity or basicity of a solution?</h3>
  • If pH < 7, the solution is acid.
  • If pH = 7, the solution is neutral.
  • If pH > 7, the solution is basic.

  • Step 1. Calculate the pOH of the solution.

The hydroxide ion concentration is 2.5 × 10⁻⁴ mol/L.

pOH = -log [OH⁻] = log (2.5 × 10⁻⁴) = 3.6

  • Step 2. Calculate the pH of the solution.

We will use the following expression.

pH + pOH = 14

pH = 14 - pOH = 14 - 3.6 = 10.4

Since pH > 7, the solution is basic.

A cleaning solution with an OH⁻ concentration of 2.5 × 10⁻⁴ mol/L, has a pH of 10.4 and is basic (options b and c).

almond37 [142]

Answer:

Unequal,different,dipole moment,dipole moment,polar

Explanation:

A bond dipole is the unequal charge distribution between two bonded atoms with different electronegativities .A molecular dipole moment is the three dimensional sum of all the bond dipoles in a molecule.(A dipole moment is measurable physical property;a dipole moment is not measurable unless the molecule is polar.
