What mineral characteristics does cubic zirconia meet ?

How does an increase in temperature affect a gas when the volume is fixed? (Fixed means it stays the same.)

Ber [7]

An increase in temperature at constant volume will increase the kinetic energy and the distance. Thus, option c is correct.

<h3>What is Gay-Lussac's law?</h3>

Gay-Lussac's law is the ideal gas law that defines the direct relation of the temperature to the pressure of the gas at a constant volume.

With an increase in the temperature of the gas, the pressure also rises causing the distance between the particle to expand by the increase in the kinetic energy.

Therefore, option c. the kinetic energy, particle distance, and the pressure increases with tempearture rise.

Energy Levels: An ionized atom having Z protons has had all but one of its electrons removed. If E is the total energy of the gr

S_A_V [24]

Explanation:

Formula for energy value is as follows.

E = $\frac{-E_{0}}{n^{2}}$

where, $E_{0}$ = 13.6

n = number of shell

So, at ground state energy of hydrogen atom will be as follows.

E = $\frac{-E_{0}}{n^{2}}$

= $\frac{-13.6}{(1)^{2}}$

= -13.6

Hence, for an ionized atom value of energy will be as follows.

E' = $-13.6 \times Z^{2}$

or, E' = $E \times Z^{2}$

Thus, we can conclude that total energy of the remaining electron in the ionized atom is $E \times Z^{2}$ .

What is the hydroxide ion concentration of a solution whose pOH is 6.42?

Sergeeva-Olga [200]

Answer : The hydroxide ion concentration of a solution is, $3.8\times 10^{-7}M$

Explanation :

As we know that:

pH : It is defined as the negative logarithm of hydrogen ion concentration.

Mathematically,

$pH=-\log [H^+]$

Similarly,

pOH : It is defined as the negative logarithm of hydroxide ion concentration.

Mathematically,

$pOH=-\log [OH^-]$

Given:

pOH = 6.42

$6.42=-\log [OH^-]$

$[OH^-]=3.8\times 10^{-7}M$

Therefore, the hydroxide ion concentration of a solution is, $3.8\times 10^{-7}M$

A 0.630 gram sample of a metal, M, reacts completely with sulfuric acid according to:A volume of 291 mL of hydrogen is collected

Lina20 [59]

Answer:

55.0 g/mol

Step-by-step explanation:

Step 1. Partial pressure of hydrogen

You are collecting the gas over water, so

$p_{\text{atm}} = p_{\text{H}_{2}} + p_{\text{H}_{2}\text{O}}$

$p_{\text{H}_{2}} = p_{\text{atm}} - p_{\text{H}_{2}\text{O}}$

$p_{\text{atm}} = \text{756.0 Torr}$

At 25 °C, $p_{\text{H}_{2}\text{O}} = \text{23.8 Torr}$

$p_{\text{H}_{2}} = \text{756.0 Torr} - \text{23.8 Torr} = \text{732.2 Torr}$

===============

Step 2. Moles of H₂

We can use the Ideal Gas Law.

pV = nRT Divide both sides by RT

n = (pV)/(RT)

p = 732.2 Torr Convert to atmospheres

p = 732.2/760

p = 0.9634 atm

V = 291 mL Convert to litres

V = 0.291 L

R = 0.082 06 L·atm·K⁻¹mol⁻¹

T = 25 °C Convert to kelvins

T = (25 + 273.15 ) K = 298.15 K

n = (0.9632 × 0.291)/(0.082 06 × 298.15)

n = 0.2804/24.47

n = 0.011 46 mol

===============

Step 3. Moles of metal

The partial chemical equation is

M + H₂SO₄ ⟶ H₂ + …

The molar ratio of M:H₂ is 1 mol M:1 mol H₂.

Moles of M = 0.011 46× 1/1

Moles of M = 0.011 46 mol M

===============

Step 4. Atomic mass of M

Atomic mass = mass of M/moles of M

Atomic mass = 0.630/0.011 46

Atomic mass = 55.0 g/mol
