Write a balanced chemical equation for the standard formation reaction of solid calcium hydroxide .
AveGali [126]

Calcium Hydroxide (Ca(OH)2) can actually be formed by the reaction of Calcium Oxide (CaO) with water (H2O). The complete balanced chemical reaction is:

<span>CaO  +  H2O  -->  Ca(OH)2</span>

 

<span>The subscript 2 in (OH) means that there are 2 O and 2 H on the product side. Hence, the equation is balanced already.</span>

How many atoms are contained in 100.0 g of mercury
Romashka [77]

3.00097 x 10^{23} atoms are contained in 100.0 g of mercury.

<h3>What is moles?</h3>

The mole is defined as the amount of substance that contains as many elementary entities as there are atoms in exactly 12 g of carbon-12.”

Number of moles of mercury = \frac{mass}{molar \;mass}

Number of moles of mercury = \frac{100.0 g}{200.59 u}

=  0.4985 moles

Number of moles of mercury = Number of atoms = moles of Hg x 6.02 X 10^{23}

= 0.4985 x 6.02 X 10^{23}

= 3.00097 x 10^{23} atoms.

Hence, 3.00097 x 10^{23} atoms are contained in 100.0 g of mercury.
