According to the site, "http://needtoknow.nas.edu/energy/energy-sources/renewable-sources/wind/" ... "Wind energy is an indirect form of solar energy created by a combination of factors, including the uneven heating of Earth’s atmosphere by solar radiation, variations in topography, and the rotation of Earth. People have been putting wind energy to use throughout history to propel sail boats, mill flour from grain, and pump water."

A total of 40 ml of titrant was required to reach a pOH of 9.00.  

6.25× 10⁻¹³ is the Kb of the conjugate base to the weak acid.

The identification of the weak acid is the first step in solving this issue. Given that the pOH is 9.00, we may get the pH as follows:

pH + pOH = 14.00

pH = 14.00 - 9.00 = 5.00

We may formulate the dissociation reaction as follows because we know that the weak acid must partially dissociate because the solution is acidic:

A- + H₃O+ = HA + H₂O

where A- is the conjugate base of the weak acid, denoted by the symbol HA.

According to the equation for the weak acid's dissociation, [A-] = [NaOH added] = 0.004 mol/L.

The weak acid's conjugate base is A-, and the following equation relates its Kb (base dissociation constant) to Ka:

Kw = Ka * Kb

where Kw (1.0 ×10⁻¹⁴ at 25°C) is the water ion product constant. Calculating Kb:

Kw = Kb = 1.0 ×10⁻¹⁴/ 0.016 = 6.25× 10⁻¹³

Therefore, 6.25× 10⁻¹³ is the Kb of the conjugate base to the weak acid.

If 2.5 g of glucose is dissolved in 0.5 dm3 of water, then the concentration of the solution will be 5 g/dm3, and the concentration of the solutes determines the concentration of the solution.

A solution is made up of both solutes and the solvent, and the amount of the solvent and solutes determine the solution concentration, such that if a solution has more solutes than the solvent, the solution will be more viscous, and here the concentration of the solution is 5 g/d\({m}^3\) (2.5 glucose/0.5 dm3).

Hence, if 2.5 g of glucose is dissolved in 0.5 dm3 of water, then the concentration of the solution will be 5 g/dm3, and the concentration of the solutes determines the concentration of the solution.

There are 0.0266 moles of N2 gas in the 960.0 ml container at 650 mmHg and 55.0 °C.

To determine the number of moles of N2 gas in the given container, we can use the ideal gas law:
PV = nRT
where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin.
First, we need to convert the temperature from Celsius to Kelvin:
T(K) = T(°C) + 273.15
T(K) = 55.0 + 273.15
T(K) = 328.15 K
Next, we need to convert the volume from milliliters to liters:
V = 960.0 mL ÷ 1000 mL/L
V = 0.960 L
Now we can plug in the values and solve for n:
n = (PV) / (RT)

n = (650 mmHg)(0.960 L) / [(0.0821 L•atm/mol•K)(328.15 K)]

n = 0.0266 mol

97.1 gram 0f NaN₃ is required to produce 50.2 L of Nitrogen gas. According to the balanced chemical reaction 2NaN₃ (s)→ 2 Na(s) + 3 N₂(g).

A chemical equation is said to be balanced if the quantity of each kind of atom in the reaction is the same on both the reactant and product sides. In a balanced chemical equation, the mass and the change are both equal.

Given:

Volume of nitrogen gas = 50.2 L

Density of nitrogen gas = 1.25 g/L

Molar mass of nitrogen = 28.02g/mol

The given reaction is 2NaN₃ (s)→ 2 Na(s) + 3 N₂(g)

Mass of NaN₃ = 50.2×1.25×1×2×65.02/1×28.02×3×1

= 8160.01/84.06

= 97.1 gram 0f NaN₃

Thus, 97.1 gram 0f NaN₃ is required to produce 50.2 L of Nitrogen gas.

The temperature at which 24.6 g of chlorine gas, Cl₂ will exert a pressure of 652 mmHg when confined in a 8.5 1 L container is -16 °C

We'll begin by obtaining the number of mole of chlorine gas, Cl₂ in the container. Details below:

Mole = mass / molar mass

Mole of of chlorine gas, Cl₂ = 24.6 / 71

Mole of of chlorine gas, Cl₂ = 0.346 mole

Finally, we shall determine the temperature. This is shown below:

PV = nRT

0.858 × 8.51 = 0.346 × 0.0821 × T

Divide both sides by (0.346 × 0.0821)

T = (0.858 × 8.51) / (0.346 × 0.0821)

T = 257 K

Subtract 273 to obtain answer in °C

T = 257 - 273

T = -16 °C

Thus, can conclude that the temperature is -16 °C

We need 17.38 mL of 1 M acetic acid to neutralize the reaction containing 1.2 g of K2CO3.

To determine how many milliliters of 1 M acetic acid are required to neutralize a reaction containing 1.2 g of K2CO3,The reaction between K2CO3 and acetic acid can be written as:

K2CO3 + 2CH3COOH → 2KCH3COO + H2O + CO2

From the balanced equation, we can see that 1 mole of K2CO3 reacts with 2 moles of acetic acid. The molar mass of K2CO3 is 138.2 g/mol, so 1.2 g of K2CO3 is equal to 1.2/138.2 = 0.00869 moles.

Since 2 moles of acetic acid are required to react with 1 mole of K2CO3, we need 2 × 0.00869 = 0.01738 moles of acetic acid. To calculate the volume of 1 M acetic acid needed, we can use the formula:

Volume (in L) = Number of moles / Molarity

Volume = 0.01738 mol / 1 M = 0.01738 L = 17.38 mL
