Answer:

Voltaic cells convert chemical energy to electrical energy by means of an oxidation-reduction reaction. Electrolytic cells convert electrical energy to chemical energy, so they are the opposite of voltaic cells. They require an input of electrical energy to cause an oxidation-reduction reaction.

Answer:

2NaBr + Cl2 =2NaCl + Br2

Explanation:

Change the coefficient in from of the NaCl so you have the same number of Cl atoms on both sides.

Change the coefficient in front of the NaBr to balance the Br atoms as well as the Na.

Answer:

Potassium iodide increases the decomposition rate of hydrogen peroxide.

Explanation:

Potassium iodide increases the decomposition rate of hydrogen peroxide because potassium iodide act as a catalyst. A catalyst speed up the process of chemical reaction without reacting with the molecules present in reaction. If the potassium iodide is not present as a catalyst for the decomposition of hydrogen peroxide then the decomposition of hydrogen peroxide takes too much time because the catalyst is absent that speed up the reaction.

22.7 degrees Celsius = 22.7 + 273 = 295.7 K

[tex]\frac{(12.2)(150.4)}{295.7}=\frac{(9.7)(101.3)}{T_{2}} \\ \\ \frac{295.7}{(12.2)(150.4)}=\frac{T_{2}}{(9.7)(101.3)} \\ \\ T_{2}=\frac{(295.7)(9.7)(101.3)}{(12.2)(150.4)} \approx \boxed{158.35 \text{ K}}[/tex]

Answer:

3.1L

Explanation: using Boyle's law p1v1=p2v2

p1=15.6,v1=?,p2=25.43,v2=1.895

manipulate the formula to favor so to find v1 the formula would be

p2v2/p1

25.43*1.895\15.6=3.1L

Answer:

0.260 Celsius

Explanation:

q =c x m x (T2-T1)

c - specific heat of water 4.186 J/g.C

T2-T1 = q /(c x m) = 0.959 /(4.186 x 0.88) = 0.959/3.68 =0.260 C

Answer:

Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth. These constantly circulating cells of hotter and cooler molten rock are thought to help heat the surface. Some geologists believe convection currents within the earth are a contributing cause of volcanoes, earthquakes, and continental drift.

Epipelagic zone

Explanation:

The Epipelagic zone is the upper most layer of the ocean. It is the layer which receives maximum sunlight, because of availability of sunlight and nutrients like fresh oxygen and atmospheric carbon dioxide, this zone is suitable for active photosynthesis activity.

Answer:

D

Explanation:

Ap3x

The accounts for the difference between curve A and curve B on the energy diagram is the reaction described by curve B is occurring with a catalyst. Therefore, option D is correct.

An energy profile is a theoretical representation of a chemical reaction or process as a single energetic pathway that transforms reactants into products.

The amount of relative potential energy in each step of a reaction is depicted by an energy diagram. Reactants, transition states, and products are typically depicted on energy diagrams. It may also include intermediates and activation energy, depending on the reaction.

An energy diagram depicts how an object's potential energy varies with position and provides information about the object's motion.The potential energy curve depicts the amount of potential energy that the boulder has at each position.

Thus, option D is correct.

Answer:

B) 16 g

Explanation:

First we convert 4 moles of O₂ into moles of H₂, using the stoichiometric coefficients of the balanced reaction:

Finally we convert 8 moles of H₂ into grams, using its molar mass:

Thus, the correct answer is option B).

Answer:

k₂ = 5 x 10⁻² s⁻¹

Explanation:

Using the Clausis - Clapyron Equation ...

ln(k₁/k₂) = ΔH/R(T₁-T₂/T₁·T₂) => lnk₂ = lnk₁ + ΔH/R(T₁-T₂/T₁·T₂)

k₁ = 6.4 x 10⁻³s⁻¹

ΔH = 33.6 Kj/mole

R = 0.008314 Kj/mol·K

T₁ = 25°C = 298K

T₂ = 75°C = 348K

lnk₂ = ln(6.4 x 10⁻³s⁻¹) + (33.6kj/mol·K/0.008314Kj/mol·K)·[(348K - 298K)/(348K)(298K)] = -3.10s⁻¹

k₂ at 75°C = exp(-3.10) = 5 x 10⁻²s⁻¹ (faster k-value at higher temp)

Hello!

In this case, when methane is burnt in the presence of carbon dioxide, the following chemical reaction is carried out:

[tex]CH_4+2O_2\rightarrow CO_2+2H_2O[/tex]

Thus, since there is a 1:2 mole ratio between methane and oxygen, we set up the following mathematical expression to obtain the produced mass of carbon dioxide as a result of the reaction:

[tex]m_{CO_2}=62.8gCH_4*\frac{1molCH_4}{16.05gCH_4}*\frac{1molCO_2}{1molCH_4} *\frac{44.01gCO_2}{1molCO_2} \\\\m_{CO_2}=172.2gCO_2[/tex]
