Explain the relationship between the number of valence electrons and the reactivity of a metal.

1 answer:

6 0

The valence electrons on atoms determine an element's reactivity. The more easily an element can attain a noble-gas electron configuration by losing or gaining a small number of electrons in its valence shell, the more reactive the element tends to be.

A sample of 8.11 g 8.11 g of solid calcium hydroxide is added to 38.0 mL 38.0 mL of 0.410 M 0.410 M aqueous hydrochloric acid. W

Andrews [41]

Answer:

The balanced chemical equation :

$Ca(OH)_2(s)+2HCl(aq)\rightarrow CaCl_2(aq)+2H_2O(l)$

Explanation:

When calcium hydroxide reacts with hydrochloric acid it gives calcium chloride and water as a products. The chemical equation is given as:

$Ca(OH)_2+2HCl\rightarrow CaCl_2+2H_2O$

According to question, solid calcium hydroxde is added to 38.0 mL of 0.410 M of HCl solution, so the chemical equation can be written as:

$Ca(OH)_2(s)+2HCl(aq)\rightarrow CaCl_2(aq)+2H_2O(l)$

According to stoichiometry, when 1 mole of solid calcium hydroxide reacts with 1 mole of hydrochloric acid to gives 1 mole of aqueous calcium chloride and 1 mole of water.

1. How many moles are contained in 2.22 x 1024 molecules of calcium fluoride?

Black_prince [1.1K]

Answer:

= 3.7moles

Explanation:

I mole = 6.022 × 10²³ molecules

I molecule = 1 ➗ 6.022 × 10²³ moles

2.22 ×10‘’ 24molecules = (2.22×10‘’ 24) ÷6.022 × 10²³ moles

Number of moles = 2.22/6.022 × 10" 24-23

Number of moles = 0.37 × 10

Number of moles = 3.7moles
