Ca(OH)2 - How many Carbon, how many oxygen, and how many hydrogen in this formula? - please explain

Chemistry
1 answer:
aksik [14]2 years ago
3 0

Answer: 1Ca + 2O + 2H

Explanation:

Ca is 1 since there is no subscript

O and H each have 2 because the subscript 2 is outside the parenthesis so you multiply their subscript (1) by 2

I NEED HELP PLEASE! :)<br><br> Describe a limiting reactant in your own words.
koban [17]

Answer:

See explanation

Explanation:

A limiting reactant is the reactant in a reaction that is done reacting first, because there are less moles of it than are needed for a full reaction with the other compound or compounds.

Hope this helps!

Which way does equilibrium shift
Natali [406]
You can use Le Chatelier's Principle to describe the equilibrium shift.

Le Chaterlier's Principle states that: "<span>If a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium moves to counteract the change."

Thus, if you heat up the reaction, the equilibrium shift favors the endothermic reaction. If you increase pressure (if gases are involved), the shift favors the reaction that produces less gaseous products (to counteract pressure) and so on.</span>

What is the difference between atomic mass, relative atomic mass and average atomic mass
vesna_86 [32]

\bold{\huge{\underline{\purple{ Answer }}}}

<u>Difference </u><u>between </u><u>Atomic </u><u>mass</u><u>, </u><u>relative </u><u>atomic </u><u>mass </u><u>and </u><u>average </u><u>atomic </u><u>mass</u><u> </u><u>:</u><u>-</u>

<h3><u>Atomic </u><u>Mass </u><u>:</u><u>-</u></h3>

  • Atomic mass is the mass of neutrons and protons present in the nucleus of an atom .
  • It is always calculated for a single element and having direct value
  • For isotopes also, the atomic mass is calculated separately . Example :- <u>Carbon </u><u>1</u><u>2</u><u> </u><u>,</u><u> </u><u>carbon </u><u>1</u><u>3</u><u> </u><u>and </u><u>carbon </u><u>1</u><u>4</u><u> </u><u>have </u><u>different </u><u>atomic </u><u>mass</u><u>. </u>
  • The SI unit of Atomic mass is " u" and "amu"

<h3><u>Relative </u><u>Atomic </u><u>mass </u><u>:</u><u>-</u></h3>

  • Relative atomic mass is mean mass of the atoms of an element which is compared to the 1/12th mass of carbon - 12 .
  • Carbon - 12 is taken as a relative when we calculate the relative atomic mass of any element
  • For calculating relative atomic mass, we need to know the masses, percentage and abundance of all types of elements
  • Relative atomic mass is a dimension less quantity

<h3><u>Average </u><u>Atomic </u><u>Mass </u><u>:</u><u>-</u></h3>

  • Average atomic mass is the average mass of an atoms of a particular element by considering it's isotopes
  • While we calculate average atomic mass is a standardized number. Whereas, Average atomic mass sometimes varies geologically .
  • It also includes percentage, abundance and masses of given element .
  • In average atomic mass, We do not compare mean value with the 1/12 mass of carbon - 12
  • The unit of Average atomic mass is "Amu" or " u " .
