What would happen to the Earth's hydrosphere if there were no atmosphere?

1 answer:

7 0

Weather happens in the atmosphere. However, without the hydrosphere there would be no water to evaporate. Therefore, no clouds or rain would form. The temperature of the Earth would rapidly start to rise once our atmosphere had disappeared. Without our atmosphere we have little protection from the Sun's heat. It would penetrate to the Earth's surface and cause the water to start boiling off into steam that would float off into space. Since we need water for survival, the lack of water from the hydrosphere would prevent all life source such as plants, animals, and humans from surviving.

A/a physical change is when an object goes through a natural change such as weather etc.
B/ the different is that 1) chemical change is more quick to change rather than physical (ex: I’d there is rocks flying around and is wearing down another rock it would take longer rather than acid)

Determine the pH of a 0.500 M HNO2 solution. Ka of HNO2 is 4.6 * 10-4.

Lostsunrise [7]

Answer: pH of solution is = 1.82

Explanation:

$HNO_2\rightarrow H^+NO_2^-$

cM 0 0

$c-c\alpha$ $c\alpha$ $c\alpha$

So dissociation constant will be:

$K_a=\frac{(c\alpha)^{2}}{c-c\alpha}$

Give c= 0.500 M and $\alpha$ = ?

$K_a=4.6\times 10^{-4}$

Putting in the values we get:

$4.6\times 10^{-4}=\frac{(0.500\times \alpha)^2}{(0.500-0.500\times \alpha)}$

$(\alpha)=0.030$

$[H^+]=c\times \alpha$

$[H^+]=0.500\times 0.030=0.015$

Also $pH=-log[H^+]$

$pH=-log[0.015]=1.82$

Thus pH of a 0.500 M $HNO_2$ solution is 1.82

Which type of bond will most likely be found in HBr?

Oksana_A [137]

H and Br are both non-metals which means the bond that comes in between them is covalent. If the composing elements are non-metal and metal, then the bond should be ionic. In this case, HBR is considered polar because the Br atom pulls on the electron much harder than the H atom. Answer is C.

What happens to the energy that is "lost" from the generator?

Troyanec [42]

The energy that is lost from the generator becomes “unusable”. This energy was emitted as heat or mechanical energy, rather than electrical energy. Energy can never be destroyed, and it wouldn’t be considered lost if it was converted into the intended product.
