Answer:

Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.

A bottle of soda has a PH of 3.

BaLLatris [955]

Answer:

The new pH of the solution $= 6$

Explanation:

Given

pH of bottle of Soda is $3$

As we know that

pH $= -$ log [H+]

We will derive the hydrogen ion concentration when pH is $3$

$3 = -$ log [H+]

Taking anti-log on both the sides, we get -

H+ ion is equal to $10^{-3}$

When the hydronuim ion concentration reduces by $\frac{1}{1000}$ of the original concentration, the new hydrogen ion concentration becomes

$\frac{1}{1000000} = 10^{-6}$

The new pH is

$= - log [ 10^{-6}]\\= 6$

Silver (ag) has a molar mass of 107. 8682 g, nitrogen has a molar mass of 14. 0067 g, and oxygen has a molar mass of 15. 9994 g.

hjlf

Answer:

M(AgNO3) = 169,8731 g mol

Explanation:

M(Ag) = 107,8682 g mol

M(N) = 14.0067 g mol

M(O) = 15.9994 g mol

M(AgNO3) = M(Ag) + M(N) + 3 x M(O) = 107.8682 + 14.0067 + 3 x 15.9994 =

= 169,8731 g mol

Just sum up all the respective elements' molar mass.
