Explanation:

The reaction between calcium hydroxide and nitric acid is as follows.

$Ca(OH)_{2} + HNO_{3} \rightarrow Ca(NO_{3})_{2} + H_{2}O$

Number of reactant atoms are as follows.

Ca = 1
O = 4
H = 3
N = 1

Number of product atoms are as follows.

Ca = 1
O = 4
H = 2
N = 3

To balance the given chemical equation, multiply $HNO_{3}$ by 2 on reactant side and multiply $H_{2}O$ by 2 on the product side.

Therefore, the balanced chemical equation will be as follows.

$Ca(OH)_{2} + 2HNO_{3} \rightarrow Ca(NO_{3})_{2} + 2H_{2}O$

How many grams of fluorine are contained in 8 molecules of boron trifluoride?

Lelu [443]

<h3>Answer:</h3>

7.57 × 10⁻²² g of F

<h3>Solution:</h3>

Data Given:

Number of Molecules = 8

M.Mass of BF₃ = 67.82 g.mol⁻¹

Mass of Fluorine atoms = ?

Step 1: Calculate Moles of BF₃

Moles = Number of Molecules ÷ 6.022 × 10²³ Molecules.mol⁻¹

Putting value,

Moles = 8 Molecules ÷ 6.022 × 10²³ Molecules.mol⁻¹

Moles = 1.33 × 10⁻²³ mol

Step 2: Calculate Mass of BF₃:

Moles = Mass ÷ M.Mass

Solving for Mass,

Mass = Moles × M.Mass

Putting values,

Mass = 1.33 × 10⁻²³ mol × 67.82 g.mol⁻¹

Mass = 9.0 × 10⁻²² g

Step 3: Calculate Mass of Fluorine Atoms:

As,

67.82 g BF₃ contains = 57 g of F

So,

9.0 × 10⁻²² g will contain = X g of F

Solving for X,

X = (9.0 × 10⁻²² g × 57 g) ÷ 67.82 g

X = 7.57 × 10⁻²² g of F

Answer:

When scientist find new species that may have to change classification systems in order to accommodate them. DNA sequencing has also let us find out more about evolutionary relationships. The more recent the common ancestor, the more closely related the two species are.

What is the reaction scheme for the experiment of synthesis of methyl salicylate

soldier1979 [14.2K]

The methyl salicylate (wintergreen oil) is the methyl ester of salicylic acid.

Methyl salicylate is produced by esterifying salicylic acid with methanol, the reaction scheme is attached to this answer. In the past, it was commonly distilled from the twigs of Betula lenta (sweet birch) and Gaultheria procumbens (eastern teaberry or wintergreen).
