Single displacement is the type of chemical reaction
Answer:
Likely to gain electrons
Explanation:
The atom shown is likely to gain additional electrons to complete its electronic configuration.
- Since this is a neutral specie, the number of protons and electrons are the same.
- The atom has 16 electrons
- the number of valence electrons is 6
- If the atom gains two additional electrons, the octet configuration is attained
- Also, the atom can lose 6 electrons to become an octet
The atom will prefer to gain additional 2 electrons to give an octet configuration.
12.) 15 : 10 Times Each One By 0.3
15*0.3= 4.5
15-4.5 = 10.5
10*0.3= 3
10-3=7
The Scale Factor Is 10.5:7
We know that Zinc (Zn) has a molar mass of 65.39
g/mol. Hence the remaining is:
136.28 - 65.39=70.89
While molar mass of Chlorine (Cl) is 35.453 g/mol .
70.89 / 35.453 =2 => Cl
<span>So the formula is ZnCl2</span>
The density of the coin, given the data from the question is 21.33 g/mL.
<h3>What is density? </h3>
The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as
Density = mass / volume
<h3>How to determine the density of the coin</h3>
From the question given above, the following data were obtained:
- Volume of coin = 2.25 L = 2.25 × 1000 = 2250 mL
- Mass of coin = 48 Kg = 48 × 1000 = 48000 g
- Density of coin =?
Density = mass / volume
Density = 48000 / 2250
Density = 21.33 g/mL
<h3>How to determine the metal</h3>
The density of the coin obtained, given the data from the question is 21.33 g/mL
