Answer:

Three units, put together in different patterns make, essentially, everything.

Explanation:

Atoms are composed of three elementary particles, protons, neutrons and electrons. As a result Chemistry and Physics have reduced the complexity of the sensible world to incredible simplicity. Three units brought together in different patterns essentially do everything.

This is because everything we know that is touchable is matter and matter is composed of atoms that are composed of three units.

A bell hanging at the top of a tower has 8,550 j of energy. If it has a mass of 20 kg find the height of the Bell
kogti [31]

43.62m

Explanation:

Given parameters:

Energy = 8550J

Mass of bell = 20kg

Unknown:

Height of the bell = ?

Solution:

As this state, the bell possesses potential energy. Potential energy is the energy at rest in a body. It is due to the position of the body.

  Potential energy = m g h

m is the mass of the body

g is the acceleration due to gravity of the body

h is the height of the body

The unknown is h and we should solve for it.

  g = 9.8m/s²

     Input the variables;

        8550 = 20  x  9.8 x h

     h = 43.62m

The element thallium is 70% thallium-205 and 30% thallium-203. Calculate its relative atomic mass to 1 decimal place.
xxMikexx [17]

Answer:

answer-

The relative atomic mass = 204.4

explanation:

Thallium -203 = 30%

Thallium -205 = 70%

Therefore ,

relative mass of thallium = (30×203 + 70×205)/100

relative mass of thallium = (20440)/100

relative mass of thallium = 204.40 amu

Thus,

relative atomic mass of thalium =204.4 ( to 1 decimal place)

Calculate ΔG o for the following reaction at 25°C: 3Mg(s) + 2Al3+(aq) ⇌ 3Mg2+(aq) + 2Al(s) Enter your answer in scientific notat
larisa [96]

Answer:

-3.7771 × 10² kJ/mol

Explanation:

Let's consider the following equation.

3 Mg(s) + 2 Al³⁺(aq) ⇌ 3 Mg²⁺(aq) + 2 Al(s)

We can calculate the standard Gibbs free energy (ΔG°) using the following expression.

ΔG° = ∑np . ΔG°f(p) - ∑nr . ΔG°f(r)

where,

n: moles

ΔG°f(): standard Gibbs free energy of formation

p: products

r: reactants

ΔG° = 3 mol × ΔG°f(Mg²⁺(aq)) + 2 mol × ΔG°f(Al(s)) - 3 mol × ΔG°f(Mg(s)) - 2 mol × ΔG°f(Al³⁺(aq))

ΔG° = 3 mol × (-456.35 kJ/mol) + 2 mol × 0 kJ/mol - 3 mol × 0 kJ/mol - 2 mol × (-495.67 kJ/mol)

ΔG° = -377.71 kJ = -3.7771 × 10² kJ

This is the standard Gibbs free energy per mole of reaction.
