<span>Gold is  a stable heavy metal that is easily formed into uniform and thin sheets of measurable property. Alpha particles are relatively massive (compared to electrons) and so deflection is less dramatic and more easily measured. This is the property that prompted Rutherford to use alpha particles and gold. </span>
The particles that are positively charged were fired at the gold foil and when it reached that goldatoms’ nuclei, which are also positively charged, the particles were repelled back

A student conducts an experiment to determine the effect of adding salt on the boiling temperature of water. The results are sho
sineoko [7]

Answer:

The answer to your question is: The first option is correct.

Explanation:

From the data given, we conclude that as the amount of salt increases, the boiling point of water increases.

Options

If salt is added to water, the water will boil at a higher temperature This is the hypothesis for the experiment.

Salt makes water boil. This statement is not true.

If water is boiling, it must have salt added to it. This statement is incorrect, it is not the goal of the experiment.

If salt is added to water, the water will get cloudy There is not evidence of that from the information given.

The reaction converting glycerol to glycerol-3-phosphate (energetically unfavorable) can be coupled with the conversion of ATP t
Brut [27]

Answer:

glycerol-3-phosphate, ADP, H⁺

Explanation:

The reaction of converting glycerol to glycerol-3-phosphate which makes is unfavorable and is coupled with the second reaction which involves conversion of ATP to ADP which is high energetically favorable.

Reaction 1:  Glycerol + HPO₄²⁻ ⇒ Glycerol-3-phosphate + water

Reaction 2:             ATP  + H₂O ⇒ ADP + HPO₄²⁻ + H⁺

The coupled reaction of both the reactions become favorable. Thus, the overall coupled reaction is:

<u>Glycerol + ATP ⇒ Glycerol-3-phosphate + ADP + H⁺</u>

The net products are = glycerol-3-phosphate, ADP, H⁺

Which of the following will stay constant, no matter if the substance is in the solid, liquid, or gas state?
34kurt
The mass of any substance will remain the same regardless of its state of matter. Using water as an example, its volume increases when it is boiled to a gas or when it is frozen from a liquid state to the solid state ice. The volume and temperature will change as it moves through the states of matter, however the amount of individual molecules of oxygen and hydrogen that form water will remain the same and this constitute mass.
