What do atoms form when they bond chemically?

1 answer:

7 0

They form molecules which can be in solution form if diluted in water, but some do form solutions on exposure to the atmosphere i.e they are deliquescent like pellets of sodium hydroxide

How many moles are 7.25 x 1023 formula units of Mgo ?

romanna [79]

Answer:

<h2>The answer is option D</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

$n = \frac{N}{L} \\$

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

$n = \frac{7.25 \times {10}^{23} }{6.02 \times {10}^{23} } = \frac{7.25}{6.02} \\ = 1.2043189368...$

We have the final answer as

<h3>1.20 moles</h3>

Hope this helps you

Calculate the volume of 0.100 m hcl required to neutralize 1.00 g of ba(oh)2 (molar mass = 171.3 g/mol).

dedylja [7]

The balanced chemical equation between HCl and $Ba(OH)_{2}$ is:

$2HCl (aq) + Ba(OH)_{2}(aq) -->BaCl_{2}(aq) + 2 H_{2}O(l)$

Moles of $Ba(OH)_{2}$ = $1.00 g Ba(OH)_{2} * \frac{1 mol Ba(OH)_{2}}{171.3 g Ba(OH)_{2}} = 0.00584 mol Ba(OH)_{2}$

Moles of HCl required to neutralize $Ba(OH)_{2}$ :

$0.00584 mol Ba(OH)_{2} * \frac{ 2 mol HCl}{1 mol Ba(OH)_{2}} = 0.01168 mol HCl$

Calculating the volume of HCl from moles and molarity:

$0.01168 mol HCl * \frac{1 L}{0.100 mol} * \frac{1000 mL}{1 L} = 116.8 mL$
