Which of the following statements is not a description of asteroids?
seraphim [82]

Answer: Most of them lie in a belt between Earth and Mars.

Explanation:

Asteroids are small rocky bodies having irregular shape size which orbit sun. Majority of the asteroids are found in a belt between orbits of Mars and Jupiter. Scientists presume that these asteroids are remains of a planet that never formed between Mars and Jupiter due to great gravitational pull of the largest planet of the solar -system - Jupiter.

Thus, the incorrect description of the asteroids is: Most of them lie in a belt between Earth and Mars.

0.005 molar Ca(OH)2 solution is used in the titration.calculate the pH oh solution
Rus_ich [418]

Ca(OH)₂: strong base

pOH = a . M

a = valence ( amount of OH⁻)

M = concentration

Ca(OH)₂ ⇒ Ca²⁺ + 2OH⁻ (2 valence)

so:

pOH = 2 x 0.005

pOH = 0.01

pH = 14 - 0.01 = 13.99
