Explain why the Earth is constantly undergoing change? *

Chemistry

gladu [14]3 years ago

The Earth faces so much change so often because of several different reasons. Like the wonderful answerer down below said, gravity is in fact using its gravity to pull things, changing the surface in doing so. But this isn't the only reason. Another reason is because of all the human activity going on. Human activity is changing the world constantly. An example of this would be cutting down trees in an environment. This takes away air, killing more and more animals and such.

Many other reasons stand for the constant evolving of the planet we know and love.

Real quick, I will tell you why i think it does from a scientific point of veiw, but I dont know for sure.

The reason that the Earth goes through so much change on a regular basis is because of Gravity. What Gravity is doing is pulling objects to the Earth that it can reach (Which you probably knew) and so when it does this, it is pulling at the earths surface as well, causing constant change.

I hope this helps you!

A 10.00 mL sample of vinegar (an aqueous solution of acetic acid) is titrated with 0.5062 M NaOH(aq) and 16.58 mL is required to
sammy [17]

Answer:

5.01%

Explanation:

Density of vinegar = mass/volume

Mass of 10.00 mL = density x volume

                           = 1.006 x 10 = 10.06 g

From the equation of reaction:

CH_3COOH(aq)+NaOH(aq)-->CH_3COONa(aq)+H_2O(l)

1 mole pf CH3COOH requires 1 mole of NaOH for neutralization.

mole of NaOH = molarity x volume

                      = 0.5062 x 0.01658

                       = 0.008392796‬ mole

0.008392796‬ mole of NaOH will therefore require 0.008392796‬ mole of CH3COOH.

mass of CH3COOH = mole x molar mass

                                     = 0.008392796‬ x 60.052

                                      = 0.504 g

Percentage by mass of acetic acid in the vinegar = 0.504/10.06 x 100%

    = 5.01%

The percent by mass of acetic acid in the vinegar is 5.01%

The mass percent of solute in a solution containing 3.73 g KBr dissolved in 131 g of H2O is:
Elina [12.6K]

\huge \underbrace \mathfrak \red{Answer}

28%

Explanation:

mass of solute(KBr) = 3.73g

mass of solvent(H2O) = 131g

mass of solution = mass of solute + mass of solvent

= 3.73 + 131

= 134.73g

\sf \large {mass \: percentage =  \frac{mass \: of \: solute}{mass \: of \: solvent}  \times 100} \\  \\  \sf  mass \: percentage =  \frac{3.73}{134.73}  \times 100 \\  \\  \sf mass \: percentage =  0.028 \times 100 \\  \\  \sf mass \: percentage = 28\%
