Answer:

ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound.

Ionic bonds form when a nonmetal and a metal exchange electrons, while covalent bonds form when electrons are shared between two nonmetals. An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions.

Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.

Determine how many grams of silver would be produced, if 12.83 x 10^23 atoms of copper react with an excess of silver nitrate. G

likoan [24]

Answer: The amount of silver produced in the given reaction is 459.63 g.

Explanation:

According to mole concept:

1 mole of an atom contains $6.022\times 10^{23}$ number of atoms.

For the given chemical equation:

$Cu+2AgNO_3\rightarrow Cu(NO_3)_2+2Ag$

By Stoichiometry of the reaction:

1 mole of copper produces 2 moles of silver.

This means that, $6.022\times 10^{23}$ number of atoms of copper produces $2\times 6.022\times 10^{23}$ number of atoms of silver.

So, $12.83\times 10^{23}$ number of atoms of copper will produce = $\frac{2\times 6.022\times 10^{23}}\times 12.83\times 10^{23}=25.66\times 10^{23}$ number of atoms of silver.

We know that:

Mass of 1 mole of silver = 107.87 g

Using mole concept:

If, $6.022\times 10^{23}$ number of atoms occupies 107.87 grams of silver atom.

So, $25.66\times 10^{23}$ number of atoms will occupy = $\frac{107.87g}{6.022\times 10^{23}}\times 25.66\times 10^{23}=459.63g$

Hence, the amount of silver produced in the given reaction is 459.63 g.

A. What is the mass of 3.47x10^26 molecules of CuCl2?

Dafna11 [192]

Answer:

77460 g

Explanation:

To solve this problem first we convert molecules into moles, using Avogadro's number:

3.47x10²⁶ molecules ÷ 6.023x10²³ molecules/mol = 576.12 moles

Then we convert 576.12 CuCl₂ moles into grams, using its molar mass:

576.12 mol * 134.45 g/mol = 77460 g

So the answer is 77460 g, or 77.46 kg.

Hydrogen gas and solid gold(III) sulfide are reacted. Pure solid gold metal is formed and gaseous hydrogen sulfide is released.

alexdok [17]

The reactants of the reaction will be solid gold (III) sulfide and hydrogen gas, while the products will be pure solid gold and hydrogen sulfide gas.

<h3>Chemical reactions</h3>

Reactants react together during reactions to arrive at products.

In this case, solid gold (III) sulfide and hydrogen gas react according to the following equation:

$Au_2S_3(s) + 3 H_2 (g)-- > 2 Au(s) + 3H_2S(g)$

Reactants = solid gold (III) sulfide, hydrogen gas

Products: pure solid gold, hydrogen sulfide gas

4 Identify What are the starting materials

Natalka [10]

Answer:

Detail is given below.

Explanation:

Photosynthesis:

Reactants = Carbon dioxide + water + energy

Products = glucose + oxygen

Chemical equation:

6H₂O + 6CO₂ + energy → C₆H₁₂O₆ + 6O₂

It is the process in which in the presence of sun light and chlorophyll by using carbon dioxide and water plants produce the oxygen and glucose.

water is supplied through the roots, carbon dioxide collected through stomata and sun light is capture by chloroplast.

Cellular respiration:

Reactants = Glucose + oxygen

Products = carbon dioxide + water + 38ATP

Chemical equation:

Glucose + oxygen → carbon dioxide + water + 38ATP

It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.
