Based on the following unbalanced reaction. how many moles of U can be 2 produced when you produce 3 moles of Z?

Three moles of an ideal gas undergo a reversible isothermal compression at temperature 18.0 ?c. during this compression, an amou

Lena [83]

We calculate the entropy of an ideal gas follows:

For an isothermal compression, change in internal energy is equal to zero.
Thus, the heat added to the gas is equal to the work done on the gas which is given as 1750 J.

Entropy would be 1750/301 = 5.81 J/K

What number is missing from this nuclear equation?

mamaluj [8]

I think the answer is A. 28 because you add 27 + 1 = 28 and add the 13AL and makes 2813AL

n200080 [17]

We are given with a mixture of sand and table sugar. The mixture has a mas s of 3.84 grams. After recovery, it was found out that there is 1.43 grams of sand. The amount of table sugar then is 3.84-1.43 or 2.41 grams. This is equal to 2.41/3.84 or 62.76% by mass/

natima [27]

Answer:

It declined drastically

Explanation:

The moths were active at night and rested by day on white birch trees, where they were effectively camouflaged from predators.

However, as the city became more industrialized, the trees were covered with black soot from the factories.

The white moths lost their camouflage, so their population declined drastically, as their predators could now find them more easily.

How do you balance the following solution Zn(s)+HCI(aq)—>ZnCI2 (aq) + H2(g)

Ierofanga [76]

Answer: The atoms of every element on both the sides of the reaction must be same.

Explanation:

We are given a chemical equation and we need to balance it. Every equation follows Law of Conservation of mass.

This law states that in a chemical reaction, the number of atoms of each element must be same on both the sides of the equation.

For the given chemical equation:

$Zn(s)+HCl(aq)\rightarrow ZnCl_2(aq)+H_2(g)$

On reactant side:

Number of zinc atoms = 1

Number of hydrogen atoms = 1

Number of chlorine atoms = 1

On product side:

Number of zinc atoms = 1

Number of hydrogen atoms = 2

Number of chlorine atoms = 2

As, the number of hydrogen and chlorine atoms on reactant and product side is not same, so we need to add a stoichiometric coefficient in-front of HCl on the reactant side. The balanced chemical equation becomes:

$Zn(s)+2HCl(aq)\rightarrow ZnCl_2(aq)+H_2(g)$
