Where are the most greenhouse gases generated during the production of electricity?

The acceleration of the block will be -2 m/s² in the backward direction.

Force is defined as the product of mass of the body and the acceleration with which it is moving. Mathematically -

F = ma

It is a vector quantity. In the three dimensional coordinate system, the force vector can be resolved as -

[F] = F[x] a[x] + F[y] a[y] + F[z] a[z]

Given is a diagram in which two forces are acting on a block.

We can write -

Force 1 on block [F1] = 4 a[x]

Force 2 on block [F2] = 8 (- a[x]) = - 8 a[x]

Resultant of forces [F] = [F1] + [F2] = 4 a[x] + ( - 8 a[x]) = - 4 a[x]

Now, we know that -

F = MA

A = F/M

In vector form, acceleration will be -

[A] = - 1/m × (4 a[x])

[A] = -1/2 × (4 a[x])

[A] = - 2 a[x]

Therefore, the acceleration of the block will be -2 m/s² in the backward direction.

Based on the redox equations;

The emf of the cell, E°cell of the cells formed from the half-reactions is 0.21 V

Reducing agents are substances which donates electrons and are oxidized in a redox reaction.

Oxidizing agents are substances which accept electrons and are reduced in a redox reaction.

From the given the redox equations:

a) O_2(g) + NO(g) + H_2O(l) → NO_3^{-}(aq) + H^{+}(aq)

b) CrO_4^{2-}(aq) + H_2O(l) + Cu(s) → Cr(OH)_3(s) + Cu(OH)_2(s) + OH^{-}(aq)

2. The emf of the cell, E°cell = E°red - E°oxi

In the cell, copper is reduced while tin is oxidized.

E°cell = (0.34 - 0.13) V

E°cell = 0.21 V

Therefore, the emf of the cell, E°cell is 0.21 V

Fill to the 250-mL mark with water after mixing a tiny amount of water with the solute to dissolve it.

Answer:

NO + O2 NO2

Explanation:

The molarity of a solution that contains 35.00 g of CuSO4 dissolved in 250.0 mL of water is 0.88M.

The molarity of a solution can be calculated using the following formula:

Molarity = no of moles/volume

According to this question, a solution consists of 35.00 g of CuSO4 dissolved in 250.0 mL of water.

no.of moles of CuSO4 = 35g ÷ 159.6g/mol

no. of moles of CuSO4 = 0.22 moles

Therefore; molarity of CuSO4 solution is calculated as follows:

M = 0.22 ÷ 0.25

M = 0.88M

Therefore, the molarity of a solution that contains 35.00 g of CuSO4 dissolved in 250.0 mL of water is 0.88M.

Explanation:

Answer:

About 7.9 L.

Explanation:

We can utilize the ideal gas law. Recall that:

[tex]\displaystyle PV = nRT[/tex]

Because the amount of carbon dioxide does not change, we can rearrange to formula to:
[tex]\displaystyle \frac{PV}{T}= nR[/tex]

Because the right-hand side stays constant, we have that:
[tex]\displaystyle \frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2} = nR[/tex]

Hence substitute initial values and known final values:
[tex]\displaystyle \begin{aligned} \frac{(793\text{ mm Hg})(4.65 \text{ L})}{(22 \text{ $^\circ$C})} & = \frac{(743 \text{ mm Hg})V_2}{(35\text{ $^\circ$C})} \\ \\ V_2 & = 7.9\text{ L}\end{aligned}[/tex]

Therefore, the final volume is about 7.9 L.
