Answer:

Therefore the loss (transfer) of this potential energy is equal to the increase in kinetic energy

Explanation:

First remember that energy is not destroyed, it only transpires

There are different types of energy, an example of different types of energy is the heat energy (the one that is transferred from an object that is hotter to another, or also by friction), the gravitational potential energy (increases when the height of an object increases with respect to the zero point) another example would be the kinetic energy (increases with increasing the speed of an object)

When object "loses" energy is really transforming into another type of energy

While an object falls and loses its potential energy (it loses height) it increases its speed (it falls faster and faster), as its speed increases the kinetic energy increases

Therefore the loss (transfer) of this potential energy is equal to the increase in kinetic energy

Calculate the mass of magnesium carbonate ( MgCO3), in grams, required to produce 110.0 g of carbon dioxide using the following
bearhunter [10]

Answer:

210.7~g~MgCO_3

Explanation:

We have to start with the <u>reaction</u>:

MgCO_3~->~MgO~+~CO_2

We have the same amount of atoms on both sides, so, we can continue. The next step is to find the <u>number of moles</u> that we have in the 110.0 g of carbon dioxide, to this, we have to know the <u>atomic mass of each atom</u>:

C: 12 g/mol

O: 16 g/mol

Mg: 23.3 g/mol

If we take into account the number of atoms in the formula, we can calculate the <u>molar mass</u> of carbon dioxide:

(12*1)+(16*2)=44~g/mol

In other words: 1~mol~CO_2=~44~g~CO_2. With this in mind, we can calculate the moles:

110~g~CO_2\frac{1~mol~CO_2}{44~g~CO_2}=25~mol~CO_2

Now, the <u>molar ratio</u> between carbon dioxide and magnesium carbonate is 1:1, so:

2.5~mol~CO_2=2.5~mol~MgCO_3

With the molar mass of MgCO_3 ((23.3*1)+(12*1)+(16*3)=84.3~g/mol. With this in mind, we can calculate the <u>grams of magnesium carbonate</u>:

2.5~mol~MgCO_3\frac{84.3~g~MgCO_3}{1~mol~MgCO_3}=210.7~g~MgCO_3

I hope it helps!

A solution is made by dissolving 4.0 moles of sodium chloride (NaCl) in 2.05 kilograms of water. If the molal boiling point cons
kozerog [31]
Properties of a solution that depend only on the ratio of the number of particles of solute and solvent in the solution are known as colligative properties. For this problem, we use boiling point elevation concept.

ΔT(boiling point)  = (Kb)mi
ΔT(boiling point)  = (0.51 C-kg / mol )(4.0 mol / 2.05 kg ) (2)
ΔT(boiling point)  = 1.99 C

T(boiling point) = 101.99 C
