PLEASE HELP WILL GIVE BRAINLIEST!!!!!!

1 answer:

This is pseudoscience, because:
1) The researchers were so excited to report that they had discovered a fuel that burns so hot that it becomes cold. - This would have to be proven again. It may not be this that caused the explosion.
2) Much to the relief of the original team or researchers, no other scientist could ever replicate their find. - It can't be replicated, so once again, it proves that it may not be that the fuel burns so hot it becomes cold
3)The researchers quickly wrote up a report, created a press release, and applied for a patent. - The report can have errors if it had been 'quickly' written. Also, because it could not be replicated, there is no need for a patent, as it could not be 'proven' again

hope this helps

In the Beer-Lambert Law equation, what does the “b” represent?

Mkey [24]

The answer is Thickness of solution.

The Beer-Lambert Law equation has the following form:

A=E×b×c

Where A is absorbance, E is the molar absorbtivity, b is the path length of the sample and c is the concentration of the compound in solution.

Lamber-Ber's law shows that the absorbance of a solution is directly proportional to the concentration of the species to be absorbed, as well as the length of the path. For example, if the length of the path is constant, the UV / VIS spectroscopy can be used to determine the concentration of the absorbent substance in the solution.

What quantity of copper is deposited by the same quantity of electricity that deposited 9g of aluminum

klio [65]

Answer:

Mass of copper deposited = 31.75 g

Explanation:

According to Faraday's second law of electrolysis, when the same quantity of electricity is passed through different electrolytes, the relative number of moles of the elements deposited are inversely proportional to the charges on the ions of the elements.

From this law, it can be seen that the higher the charge, the lower the number of moles of a given element deposited.

Number of moles of aluminium in 9 g of aluminium = mass / molar mass

Molar mass of aluminium = 27 g

Number of moles of aluminium = 9/27 = 1/3 moles

Charge on aluminium ion = +3

3 moles of electrons will discharge 1 mole of aluminium,

1 mole of electrons will discharge 1/3 moles of aluminium

Number of moles of electrons involved = 1 mole of electrons

Charge on copper ion = +2

1 mole of electrons will discharge 1/2 moles of copper.

Mass of 1/2 moles of copper = number of moles × molar mass of copper

Molar mass of copper = 63.5 g

Mass of copper deposited = 1/2 × 63.5 = 31.75 g

Why are salt and sugar both able to dissolve in water, even though the solutes have different types of chemical bonding? (3 poin

Elza [17]

Answer:

Salt's ions and sugar's polar bonds are both attracted to the polar water molecules.

Explanation:

Water is regarded as a universal solvent because of its ability to dissolve more substances than any other liquid. This unique property of water is attributed to its POLAR NATURE. Water is a polar molecule and hence, most if not all polar substances will dissolve in it.

Although salt and sugar are substances that have different types of chemical bonding in their structure but they both dissolve in water. This is because they are both polar substances and hence, their polar charges are attracted to the polar molecules of water. This attraction causes an interaction and subsequently dissolution.
