Convert the scientific notation to a decimal number. Type the correct answer in the box. 4 × 10-5 cm = cm
MakcuM [25]

Answer:

4 * 10^{-5}cm = 0.00004cm

Explanation:

Given

4 * 10^{-5}cm = [\ ]cm

Required

Solve

Apply law of indices

4 * \frac{1}{10^5}cm = [\ ]cm

Evaluate 10^5

4 * \frac{1}{100000}cm = [\ ]cm

4 * 0.00001cm = [\ ]cm

0.00004cm = [\ ]cm

Hence:

4 * 10^{-5}cm = 0.00004cm

What is an ion? Describe and give an example.
Goshia [24]
An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom. An example is Iron (III) , Iron (II) , lithium, and hydrogen.

Hypothesis: Explain the relationship between forward and reverse reactions at equilibrium and predict how changing the amount of
postnew [5]

Explanation:

forward reaction

a reaction in which reactent react to form product is known as forward reaction

reverse reaction

a reaction in which product react to form reactent is known as reverse reaction

At equilibrium stage

In a chemical equilibrium, the forward and reverse reactions occur at equal rates, and the concentrations of products and reactants remain constant. A catalyst speeds up the rate of a chemical reaction, but has no effect upon the equilibrium position for that reaction.

changing amount of reactent and product

lechatlier principle

" if you impose any change in concentration ( reactant or product) , temperature or pressure on chemical system, the system response in that way that opposes the change "

The melting point of copper is 1084 Celsius. How does the energy of the particles in a certain amount of liquid copper compare t
matrenka [14]
The melting point of the solid form of water, which is ice, is 0°C. When we convert both temperatures to kelvin by adding 273 to each we get the melting point of copper as 1357K and that of ice is 273K. Then, dividing the melting point of copper by the melting point of ice, both in absolute temperature scale. The answer would be 4.97. Thus, the energy of molecules of copper is approximately {five} times compared to that of water
