according to the following reaction:
2FeCl3 + H2S → 2FeCl2 + 2HCl+S , then which of the
following statements is true?

Answer:

Sorry I’m not rlly sure but maybe the 2nd or the last

Explanation:

Answer:

K = [HI]² / [H₂] [I₂]

Explanation:

To write the expression of equilibrium constant, K, it is important that we know how to obtain the equilibrium constant.

The equilibrium constant, K for a given reaction is simply defined as the ratio of the concentration of the products raised to their coefficient to the concentration of the reactants raised to their coefficient. Thus, the equilibrium constant is written as follow:

K = [Product] / [Reactant]

Now, we shall determine the equilibrium constant for the reaction given in the question above. This can be obtained as illustrated below:

H₂(g) + I₂(g) —> 2HI (g)

K = [HI]² / [H₂] [I₂]

Answer:

The role of consumers in an ecosystem is to obtain energy by feeding on other organisms and sometimes transfer energy to other consumers. Changes that affect consumers can impact other organisms within the ecosystem.

Explanation:

Hope this helped Mark BRAINLIEST!!!!

Consumers are organisms that obtain energy by eating other organisms. Consumers may consume either producers or other consumers. Consumers include animals.

A food chain is a network of links in a food web that begins with producer organisms and ends with an apex predator, detritivore, or decomposer species.

A food chain also demonstrates how organisms are related to one another through the food they consume. Each trophic level is represented by a different level of a food chain.

Producers can produce their own food and energy, but consumers are not the same. Consumers are living things that must hunt, gather, and eat their food.

Thus, Consumers must eat in order to gain energy, or they will perish. Omnivores, carnivores, herbivores, and decomposers are the four types of consumers.

First the burning wood inside the wood stove gives off radiation heat and transfers it into the air inside the wood stove. This hot air then heats up the metal that the wood stove is made of; the metal is heated through conduction heat transfer.

The heat of the burning wood spread in the small room via radiation and convection.

Convection can be described as the transfer of heat from one place to another due to the movement of fluid. Convective heat transfer involves the combined processes of conduction and advection.

Gases and liquids are not good conductors of heat under normal temperature and pressure conditions, but they can easily transfer heat.

The convection takes place other through diffusion or advection but does not take place in solids, because there is no movement of its constituent particles happens. The diffusion of heat that occurs in solids is known as thermal conduction.

Heat transfer that takes place between a surface and a liquid that is in contact with the surface is known as convection heat transfer.  Therefore, the heat of the wood-burning stove spread in the entire room through radiation and convection.

Answer:

Distance = 18 meters

Explanation:

Given the following data;

Force = 50 N

Speed = 1.5 m/s

Time = 12 seconds

To find the distance travelled;

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the equation;

[tex]Speed = \frac{distance}{time}[/tex]

Making distance the subject of formula, we have;

Distance = speed * time

Substituting into the formula, we have;

Distance = 1.5 * 12

Distance = 18 meters

Additionally, to find the workdone;

Workdone = force * distance

Workdone = 50 * 18

Workdone = 900 Joules

Answer:

The new pressure of the gas is 1080 mmHg

Explanation:

The general equation provides a way to calculate the relationship between changesnp in volume, temperature and pressure of a given mass of gas.

The general gas equation is given as P1V1/T1 = P2V2/T2

Where P1 is initial pressure of gas

V1 is initial volume of gas

T1 is initial temperature of gas

P2 is final pressure of gas

V2 is final volume of gas

T2 is final temperature of gas

From the given question, P1 = 900 mmHg, V1 = 0.8 L, T1 = 400 K, P2 = ?, V2 = 0.5 L, T2 = 300 K

Making P2 subject of the general gas equations:

P2 = P1V1T2/V2T1

P2 = (900 × 0.8 × 300) / (0.5 × 400)

P2 = 1080 mmHg

Therefore, the new pressure of the gas is 1080 mmHg.

Answer: The molarity of final solution is 0.244 M.

Explanation:

Given: [tex]M_{1}[/tex] = 1.00 M,       [tex]V_{1}[/tex] = 0.305 L

[tex]M_{2}[/tex] = ?,                [tex]V_{2}[/tex] = 1.25 L

Formula used to calculate the molarity f resulting solution is as follows.

[tex]M_{1}V_{1} = M_{2}V_{2}[/tex]

Substitute the values into above formula as follows.

[tex]M_{1}V_{1} = M_{2}V_{2}\\1.00 M \times 0.305 L = M_{2} \times 1.25 L\\M_{2} = \frac{1.00 M \times 0.305 L}{1.25 L}\\= 0.244 M[/tex]

Thus, we can conclude that the molarity of final solution is 0.244 M.
