Why do solids exist ?

Chemistry

Answer:

A solid's particles are packed closely together. The forces between the particles are strong enough that the particles cannot move freely; they can only vibrate. As a result, a solid has a stable, definite shape and a definite volume. Solids can only change shape under force, as when broken or cut.

Explanation:

1)<u> Convert the distance, 13.1 km to miles</u>

  • Conversion factor:

        1 = 1 mi / 1.61 km

2)<u> Use 6.2 mi/h as a converstion factor between distance and time</u>

  • 8.1366 mi × 1 / [6.2 mi/h] = 1.3124 h

3) <u>Convert 1.3124 h to minutes</u>

  • 1.3124 h × [ 60 min/h] = 78.7 min

Rounding to the nearest minutes (two significant figures):

What is the purpose of galvanization?​
frutty [35]
Galvanizing protects from rust in a number of ways: It forms a barrier that prevents corrosive substances from reaching the underlying steel or iron. The zinc serves as a sacrificial anode so that even if the coating is scratched, the exposed steel will still be protected by the remaining zinc.

KOH (aq) + HCl (aq) --> KCl (aq) + H20 (l).

KOH is a base, because OH can accept a H+.
HCl is an acid because it can donate a H+.

In general, bases are : OH-, and acids are : H+.
