Answer:
5.12 molecules of Ag₂S could be produced from 10 molecules of silver.
Explanation:
Given data:
Molecules of Ag = 10 molecules
Molecules of Ag₂S = ?
Solution:
First of all we will convert the number of molecules into gram.
10/ 6.022 ×10²³ = 1.7 × 10⁻²³ mol
Mass of Ag:
Number of moles = mass/ molar mass
Mass = Number of moles × molar mass
Mass = 1.7 × 10⁻²³ mol × 107.9 g/mol
Mass = 183.43 × 10⁻²³ g
Chemical equation:
2Ag + H₂S → Ag₂S + H₂
Now we will compare the moles of silver with Ag₂S from balanced chemical equation.
Ag : Ag₂S
2 : 1
1.7 × 10⁻²³ : 1/2 ×1.7 × 10⁻²³ = 0.85 × 10⁻²³ mol
Molecules of Ag₂S:
0.85 × 10⁻²³ × 6.022 ×10²³ = 5.12 molecules
Answer;
Solvent
Explanation;
-A solution is a homogeneous mixture that is made of two or more substances. In other words, It is a mixture in which one of the substances dissolves in the other. The substance which dissolves is called the solute while the substance that dissolves the solute is called the solvent.
-In a solution of a carbonated beverage, water acts as the solvent which dissolves the components added as solute to make the beverage. These components include sugars and other types of salts such as sodium citrate, all dissolved in water.
Answer:
It is solid
Explanation:
Well a can i hard and solid because it is metal
Answer:
Explanation:
Most of this ancient space rubble can be found orbiting the Sun between Mars and Jupiter within the main asteroid belt. Asteroids range in size from Vesta – the largest at about 329 miles (530 kilometers) in diameter – to bodies that are less than 33 feet (10 meters) across.
Given what we know, we can confirm that the type of van der Waals interactions that occur between molecules of O2, SCl2, and CH4 in liquids of these substances are the presence of <u>London dispersion forces</u>.
<h3>What are London dispersion forces?</h3>
- They are a force of attraction between atoms.
- They are generated by electrostatic attraction.
- These forces are common between atoms in close proximity and occur often when compounds have a symmetrical distribution of atoms.
- They are generated by the formation of temporary dipoles.
Therefore, given the symmetry of the atoms disposition in these compounds and the temporary dipoles generated by the atoms being in close proximity, we can confirm that the van der Waals forces present in each compound are London dispersion forces.
