5. Some undiluted acids are more corrosive when diluted
wlad13 [49]

Answer:

The correct answer is : due to the hydrogen ions reacts and release high amount of energy with the strong acid.

Explanation:

Diluted acids are more corrosive then undiluted due to the presence of more H+ ions than the undiluted acids. The More the H+ ions are added the more corrosive the acid is.

When water is mixed with strong acid the hydrogen ions reacts with acid ions and a exothermic reaction takes place that release high amount of energy which boils violently, to avoid any accident it is advised to lab workers to wipe  if any splash self before washing.

Thus, the correct answer is : due to the hydrogen ions reacts and release high amount of energy with the strong acid.

What happens to the matter in an egg when it gets cooked ?
Irina-Kira [14]

It's the proteins that cause the egg white to solidify when you cook it. If you keep the heat turned up too high or too long when you cook an egg, the proteins in the egg white form more and more bonds, squeezing some of the water out of the protein network and making the egg white rubbery.

Concentration of sodium (Na ) outside of the cell is lower than it is inside the cell. However, the cell utilizes a membrane pro
solong [7]

Answer:

True, by active transport

Explanation:

The influx and efflux of molecules through the cell membrane depend on the concentration gradient.

When the molecules down their concentration gradient that is from higher concentration to lower concentration are known as passive transport but sometimes the cell has to transport the ions against the concentration gradient.

When the ions move against the concentration gradient, they use energy in the form of ATP molecules and then transport the ions. This is known as active transport.

In the given question, since the sodium ions move inside the cell against the concentration gradient by the active transport.
