Suppose that you put a mass of 10 g of hydrochloric acid and 20 g of magnesium bicarbonate into the reaction; however, you only

weigh a product of 5g wet magnesium chloride. Is mass conserved in this reaction? Where would the other products have gone? Explain your reasoning.

Suppose a system receives a "deposit" of work from the surroundings and loses a "withdrawal" of heat to the surroundings. Can we

Mars2501 [29]

Answer:

A. No, because we are not given specific values for w and q.

Explanation:

The change of internal energy of a system is:

ΔE = q + w

where q represents heat and w represents work.

It is necessary to know the magnitude and the sign of q and w in order to know if the system's internal energy is increasing or decreasing.

A compound of copper and sulfur contains 88.39 g of metal and 44.61 g of nonmetaL How many grams of copper are in 5264 kg of com

Dahasolnce [82]

Answer :

The mass of copper in 5264 kg of compound are, 3498383.158 g

The mass of sulfur in 5264 kg of compound are, 1765616.842 g

Explanation : Given,

Mass of metal = 88.39 g

Mass of non-metal = 44.61 g

Given mass of compound = 5264 kg = 5264000 g (1 kg = 1000 g)

Now we have to calculate the total mass of compound.

Total mass of compound = Mass of metal + Mass of non-metal

Total mass of compound = 88.39 + 44.61 = 133 g

Now we have to calculate the mass of copper.

As, 133 g of compound contains 88.39 g of copper

So, 5264000 g of compound contains $\frac{5264000}{133}\times 88.39=3498383.158g$ of copper

The mass of copper in 5264 kg of compound are, 3498383.158 g

Now we have to calculate the mass of sulfur.

As, 133 g of compound contains 44.61 g of sulfur

So, 5264000 g of compound contains $\frac{5264000}{133}\times 44.61=1765616.842g$ of sulfur

The mass of sulfur in 5264 kg of compound are, 1765616.842 g

What is the mass of 4.85 X 10^22 atoms of iron (Fe)?

ludmilkaskok [199]

Answer:

Mass = 4.5 g

Explanation:

Given data:

Number of atoms of iron = 4.85 ×10²² atoms

Mass of iron = ?

Solution:

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.

For example,

4.85 × 10²² atoms of iron / 6.022 × 10²³ atoms × 1 mol

0.081 mol

Mass of iron:

Mass = number of moles × molar mass

Mass = 0.081 mol × 55.85 g/mol

Mass = 4.5 g
