Increasing temperature increases solubility so that 480 grams (g) of sugar makes a saturated solution in 100 milliliters (mL) of

boiling water. If you add 240 g of sugar to 50 mL of boiling water, which will the solution be?

Solubility at 100 °C = 480 g / 100 mL of solution =: saturated solution

The proportion 240 g / 50 mL  is equal to the saturated ratio 480 g / 100 mL

Then, 240 g of sugar in 50 mL of boiling water will make a saturated solution.

Answer: saturated

Explain two advantages and disadvantages of using energy created by nuclear fission and nuclear fusion.
alisha [4.7K]
A. NUCLEAR FUSION  is the combination of two atomic nuclei in order to create an atom that in turn creates energy.

A.1 DISADVANTAGES

1. Expensive Construction Costs-
To be able to put up such powerhouse, it needs ostentatious financial support to create a facility and gather experts and scientists.

2. Energy Input vs Energy Output- 
To be able to fuse the two nuclei together, there is a great demand for high levels of heat. Thus to be able to produce large amount of energy, it also needs a large amount of thermal energy which is not reasonable enough.

A.2 ADVANTAGES

1. Barely Any Waste- 
the only by product of nuclear fusion is helium and it is non toxic. This does not cause any harm to the environment and to people.

2. Unlimited Fuel- 
All of the components needed to produce energy can be made. Deuterium, which is the main ingredient needed to supply a truly unlimited and sustainable energy supply, can be distilled from the sea water.


B. NUCLEAR FISSION- refers to the process of splitting of the nucleus of an atom into several smaller particles to produce free neutrons and lighter elements.

B.1 DISADVANTAGES

1. It can be dangerous for employees- 
Radiation which is one of the byproducts of nuclear fission can be harmful to the personnel working within its premises.

2. It has high initial expenses- 
Nuclear power plants needs a specialized equipment for it to become functional. 

B.2 ADVANTAGES


1. It helps minimize environmental pollution- 
Nuclear power plants can produce large amounts of energy while consuming relatively minimal amount of fossil fuel. To explain further, consumption and usage of fossil fuel poses adverse effect in the environment because it can emit carbon dioxide and other harmful chemicals.

2. It helps reduce global warming- If the world would opt for nuclear fission, then there would be less greenhouse gasses in the atmosphere. This in turn would mitigate global warming.

1.Chlorobenzene, C6H5Cl, is used in the production of chemicals such as aspirin and dyes. One way that chlorobenzene is prepared
miv72 [106K]

Answer:

m_{C_6H_5Cl}=65.7gC_6H_5Cl

Explanation:

Hello!

In this case, according to the given balanced chemical reaction:

C_6H_6 (l) + Cl_2 (g) \rightarrow C_6H_5Cl (s) + HCl (g)

We can see there is 1:1 between benzene and chlorobenzene as the relavant product; thus, since the molar mass of benzene is 78.11 g/mol and that of chlorobenzene is 112.55 g/mol, the theoretical yield for this reaction turns out:

m_{C_6H_5Cl}=45.6gC_6H_6*\frac{1molC_6H_6}{78.11gC_6H_6 }*\frac{1molC_6H_5Cl}{1molC_6H_6}*\frac{112.55gC_6H_5Cl}{1molC_6H_5Cl}   \\\\m_{C_6H_5Cl}=65.7gC_6H_5Cl

Best regards!
