The unknown material : gold

<h3>Further explanation  </h3>

Density is a quantity derived from the mass and volume  

Density is the ratio of mass per unit volume  

Density formula:  

\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}

ρ = density  

m = mass  

v = volume  

mass of unknown material : 15.06 g

volume : 0.78 ml

The density of unknown material :

\tt \rho=\dfrac{15.06}{0.78}\\\\\rho=19.31~g/ml

Materials that match the density: gold

How many moles of sodium atoms do you have if you have 5.60 ~
Papessa [141]

Answer:

0.93 mol

Explanation:

Given data:

Number of moles of Na atom = ?

Number of atoms = 5.60× 10²³

Solution:

Avogadro number:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance. The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ atoms

5.60× 10²³ atoms ×  1 mol / 6.022 × 10²³ atoms

0.93 mol

What is the general form of a chemical reaction
Eddi Din [679]
So there are basically five types of chemical reactions which have their general formulas.

They are:
1. Combination reaction
General formula : A+B = AB

2. Decomposition reaction
General formula: AB = A+B

3. Single displacement reaction
General formula: AB+C = CB + A

4. Double displacement reaction
General formula: AB+CD = CB+AD

5. Acid-base reaction
General formula: A+B = S+W


You should check and compare with examples.
