Why does limestone react to acid rain, but sandstone does not?

motikmotik

Answer:

Sandstone does not react with Hydrochloric acid. The acid soaks into the rock because the rock is porous, filled with tiny holes. It is made up of tiny grains of sand cemented together by intense pressure.

Two balloons having the same charge of 1.2 × 10-6 coulombs each are kept 5.0 × 10-1 meters apart. What is the magnitude of the r

Pavel [41]

The answer is 5.2 × 10-2 newtons.

To calculate this, we will use Coulomb's Law:
F = $\frac{k * Q_{1} * Q_{2} }{ r^{2} }$
where F is repulcive force, k is constant, Q is charge, r is distance between charges.

If:
 $Q_{1}$ = $Q_{2}$ = 1.2 × $10^{-6}$ C²
r = 5.0 × $10^{-1}$ C²
k = 5.0 × $10^{9}$ $\frac{N*m^{2} }{ C^{2} }$

Then:
 $F = \frac{5.0* 10^{-1} \frac{N* m^{2} }{ C^{2}} * 1.2 * 10^{-6} C * 1.2 * 10^{-6} C }{(5.0* 10^{-1} m)^{2}}$
⇒ $F= \frac{9 * 1.2 * 1.2 * 10^{-3} N }{25* 10^{1} }$
⇒ $F = \frac{12.96* 10^{-2} }{25} N$
⇒ $F = 5.2 N$
