Explain why the law of conservation of energy can mean that we do not have unlimited sources of energy.
oee [108]
<span>The law of conservation of energy states that energy can neither be created nor destroyed - it can only be converted from one form to another. It basically means that energy can't just appear, but has to be converted from existing energy; for example, the chemical energy in petrol is turned into electrical energy to power a car.Remember the total energy of universe is constant,,and no more energy can be drawn from out if we collect all universe's energy at a single point(its the big bang energy splitted during </span>

Why dose a small container have more pressure than a large container of both have the same amount of gas in them
Volgvan
Because in a smaller container, there is less room for the gas to exist. the gas much all push together closer to fit in the smaller container. as gas atoms, they have less room to bounce around. in a bigger container, it has more room to more and is less pressurized

The pH of saliva is normally in the range of 6.4 to 7.0. However, when a person is ill, the person's saliva becomes more acidic.
aleksley [76]

Answer:

Concentration of hydrogen ion, [H^+]=5.0118*10^{-6} M

Explanation:

pH is defined as the negative logarithm of hydrogen ion's concentration.

The lower the value of pH, the higher the acidic the solution is.

The formula for pH can be written as:

pH=-log[H^+]

Given,

pH of the saliva of Marco = 5.3

To calculate: Hydrogen ion concentration in the saliva

Thus, applying in the formula as:

pH=-log[H^+]

5.3=-log[H^+]

So,

log[H^+]=-5.3

[H^+]=10^{(-5.3)}

[H^+]=5.0118*10^{-6} M
