Answer: ABOUT 71% PERCENT OF EARTH'S SURFACE IS WATER COVERED,OUT OF THAT ONLY 2.5 %IS FRESH WATER.WE GETS DRINKING WATER FROM CLEAN RIVERS ,LAKES AND EVEN GROUND WATER. WE ALSO FILTERS THE SEA WATERS TOO.

WE HUMANS ARE THE ONE WHO ACTUALLY POLLUTE  THE WATER BODIES, BECAUSE WE THROW DOMESTIC AND INDUSTRY WASTES IN THE WATER BODIES AND THE AQUATIC ANIMALS ARE DYING BECAUSE OF THIS ACT. IF WE SAVE  THE WATER BODIES THEN THERE WOULD NO BE ANY POLLUTION etc

Which statement best relates the strength and concentration of a base? At high enough concentrations, a weak base becomes strong
Lorico [155]

Answer: Option (b) is the correct answer.

Explanation:

When there are more number of hydroxide ions in a solution then there will be high concentration of OH^{-} or hydroxide ions. As a result, more will be the strength of base in that particular solution.

A base is strong when it readily dissociate into its ions in the solution. When a base is strong, then it does not matter at what concentration it is dissolved in the solution because despite of its low concentration it will remain a strong base.

Thus, we can conclude that out of the given options, the statement even at low concentrations, a strong base is strong best relates the strength and concentration of a base.

A sample of 250 g of water are heated from 40°C to 121°C, calculate the amount of heat energy absorbed.
Marysya12 [62]

Answer:

the anwser isn't in the choices

Explanation:

H=MC(change of temp.)

M=mass of water=250g

C=specific heat of water = 4.186 j/g

change in temperature is 121-40= 81

H= 250x4.186x81=84766.5J

Is there a way to stop radioactive decay?
Wittaler [7]
The chain reaction is easy to stop. Just add a neuron absorbing material. The Control Rods in rectors can do that You just SCRAM (put the rods all the way in) or add something like Boron and the chain reaction stops. 

<span>The problem is the radioactive waste. Those isotopes break down and release heat spontaneously, no neutrons required. The only known way to stop or slow radioactive decay down is to slow time down by moving at relativistic speed or near orbit to a black hole.</span>
