Answer: The correct option is C.

Explanation: For a given chemical reaction:

R+XY\rightarrow RX+Y

The mass of product, RX formed in the reaction = 47.0 g

Theoretical yield of the product, RX = 56.0 g

To calculate percent yield, we use the formula:

\%\text{ yield}=\frac{\text{Actual yield}}{\text{Theoretical yield}}\times 100

Putting the values in above equation, we get:

\%\text{ yield}=\frac{47.0g}{56.0g}\times 100

Percent yield = 83.9%

Compare urban and rural land .how are each used?
Ksivusya [100]

Answer:

"Urban area is used for the buildings, industries etc, whereas the rural areas are used for cultivation, forest cover etc."

Explanation:

When we talk about the urban land they are mostly covered with buildings, industries, roads and apartments and also the municipal structures. But when we talk about the rural land it has less dense population with forest cover, agricultural lands, rangeland and also different land cover type. In the urban areas the population density is very high. Those areas that located in the outskirt of the town are the rural areas.

Answer:

Fusion

Explanation:

Fission definition:

   In nuclear physics and nuclear chemistry, nuclear fission is a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into two or more smaller, lighter nuclei.

Fusion definition:

   Nuclear fusion is the process by which two or more atomic nuclei join together, or “fuse,” to form a single heavier nucleus. During this process, matter is not conserved because some of the mass of the fusing nuclei is converted to energy, which is released.

Both together: (vs.)

Both fission and fusion are nuclear reactions that produce energy, but the applications are not the same. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy.

Explain why it is necessary to balance chemical equations in terms of maintaining equilibrium. How can you tell when a chemical
LUCKY_DIMON [66]

Answer:

See explanation.

Explanation:

Hello,

In this case, we say that chemical reactions are governed by the law of conservation of mass, which states that matter cannot be neither created nor destroyed by transformed, for that reason, we need to balance chemical reactions in order to ensure all the atoms to be in the same quantity at both reactants and products.

Moreover, equilibrium is defined as such condition at which the concentration of both reactants and products stop changing over the time so they become constant as well as their null reaction rate.

A widely acknowledged reaction is the HABER one which consists on the synthesis of ammonia by using elemental nitrogen and hydrogen:

N_2(g)+3H_2(g)\rightleftharpoons 2NH_3(g)

In such reaction, we have two nitrogens at both reatants and products and six hydrogens at at both reatants and products for us to obey the law of conservation of mass. Furthermore, as the time goes by, nitrogen reacts with hydrogen, nonetheless, they do not react indefinitely, they have a limit that is equilibrium, so their moles stop being consumed and remain unchanged as well as the produced moles of ammonia.

Best regards.
