Answer:

1.40 M [OH⁻]

Explanation:

This compound dissociates into 3 ions, but since we are asked about [OH⁻], it's only 2. Therefore, multiply the molarity of the solution by the number of ions that [OH⁻] dissociates into:

2 × 0.70 M = 1.40 M

Answer:

Molarity of a solution where one mole of NaOH is added to 2000mL of water is 0.0005

Explanation:

Molarity is the equal to number of moles of solute divided by total volume of solvent

Given -

Number of moles of solute i.e  NaOH = 1

Total volume of solvent i.e water = 2000 mL

Molarity [tex]\frac{1}{2000} = 0.0005[/tex]

Answer:

1750

Explanation:

Greenhouse gases are those gases that are believed to contribute to the rise in the temperature of the earth by trapping infrared rays close to the surface of the earth.

Prominent among the greenhouse gases are; N2O, methane and CO2.

From the chart, we can see that the lowest sum of concentration of greenhouse gases measured in ppm was obtained in 1750. Thus this period  shows the lowest composition of greenhouse gases.

Answer:

a) 0.06 mol K₂(CO₃) and 0.07 mol Al(NO₃)₃

b) The limiting reactant is K₂CO₃

c) 0.03 moles of Al₂(CO₃)₃

Explanation:

The balanced reaction between K₂CO₃ and Al(NO₃)₃ is the following:

3 K₂CO₃ + 2 Al(NO₃)₃ → Al₂(CO₃)₃ + 6 KNO₃

(a) We can calculate the moles for each reactant as the product of the molarity (M) and the volume (V) in liters.

K₂(CO₃): M = 2.4 mol/L , V = 25 mL x 1 L/1000 mL = 0.025 L

⇒ moles K₂(CO₃) = M x V = 2.4 mol/L x 0.025 L = 0.06 mol K₂(CO₃)

Al(NO₃)₃: M = 2.0 mol/L , V = 35 mL x 1 L/1000 mL = 0.035 L

⇒ moles Al(NO₃)₃ = M x V = 2.0 mol/L x 0.035 L = 0.07 mol Al(NO₃)₃

(b) According to the balanced equation, the stoichiometric ratio is 3 moles K₂CO₃/2 moles Al(NO₃)₃. We have 0.07 moles of Al(NO₃)₃, so we multiply the moles of Al(NO₃)₃ by the stiochiometric ratio to calculate how many moles of K₂CO₃ are needed:

0.07 mol Al(NO₃)₃ x 3 mol K₂CO₃/2 mol Al(NO₃)₃ = 0.105 moles of K₂CO₃

We need 0.105 moles of K₂CO₃ but we have only 0.06 moles of K₂CO₃. Therefore, the limiting reactant is K₂CO₃.

(c) We use the limiting reactant to calculate how many moles of product (Al₂(CO₃)₃) are formed. According to the equation, 2 moles of K₂CO₃ produce 1 mol of Al₂(CO₃)₃, thus the stoichiometric ratio is 1 mol Al₂(CO₃)₃/2 moles K₂CO₃. We have 0.06 moles of K₂CO₃, so the number of moles of Al₂(CO₃)₃ will be:

0.06 moles K₂CO₃ x 1 mol Al₂(CO₃)₃/2 moles K₂CO₃ = 0.03 moles of Al₂(CO₃)₃

Answer:

9.91 mL

Explanation:

Using the combined gas law equation as follows;

P1V1/T1 = P2V2/T2

Where;

P1 = initial pressure (torr)

P2 = final pressure (torr)

V1 = initial volume (mL)

V2 = final volume (mL)

T1 = initial temperature (K)

T2 = final temperature (K)

According to the information provided in this question;

V1 = 15.0mL

V2 = ?

P1 = 760 torr

P2 = 1252 torr

T1 = 10°C = 10 + 273 = 283K

T2 = 35°C = 35 + 273 = 308K

Using P1V1/T1 = P2V2/T2

760 × 15/283 = 1252 × V2/308

11400/283 = 1252V2/308

Cross multiply

11400 × 308 = 283 × 1252V2

3511200 = 354316V2

V2 = 3511200 ÷ 354316

V2 = 9.91 mL

Answer:

C

Explanation:

Answer:

c

Explanation:

37Ca and 53Fe have the same decay mode.

Three of the most common types of decay are alpha decay (α-decay), beta decay (β-decay), and gamma decay (γ-decay), all of which involve emitting one or more particles.

The most likely mode of decay for a neutron-rich nucleus is one that converts a neutron into a proton. Every neutron-rich radioactive isotope with an atomic number smaller than 83 decays by electron emission. C, 32P, and 35S, for example, are all neutron-rich nuclei that decay by the emission of an electron.

Answer:

The pressure of the gas would be 3.06 atm

Explanation:

Amonton's law states that the pressure is directly proportional to the absolute temperature of a gas under constant volume. The equation is:

P1 / T1 = P2 / T2

Where P1 is the initial pressure = 3.16atm

T1 is initial absolute temperature = 273.15 + 32.2°C = 305.35K

P2 is our incognite

And T2 is = 273.15 + 22.9°C = 296.05K

Replacing:

3.16atm / 305.35K = P2 / 296.05K

3.06 atm = P2
