How many atoms of gold (Au) are equal to 212g of gold?
Lostsunrise [7]

Given :

Mass of gold ( Au ) is 212 gram.

To Find :

Atoms of gold present in 212 gram of gold.

Solution :

Molecular mass of gold is 197 gram.

So, number of moles of gold in 212 gram is :

n = \dfrac{212}{197} \ moles\\\\n = 1.076 \ moles

Now, we know 1 mole of any element contains 6.022 \times 10^{23} atoms.

So, number of atoms present in 1.076 moles are :

N = 1.076 \times 6.022\times 10^{23}\\\\N = 6.48 \times 10^{23}

Hence, this is the required solution.

Suppose 180 ml of 3.52x10^-4 M NaOH is mixed with 220 mL of 2.47x10^-4 M MgCl2.
velikii [3]
When in water, MgCl2 dissociates into magnesium ions and Cl- ions and NaOH into Na and OH ions. The equation is as follows:

MgCl2 = Mg2+ + 2Cl-
NaOH = Na+ + OH-

The initial concentrations are as follows:

[Mg2+] = .220(<span> 2.47x10^-4) / .220+.180 = 1.36x10^-4 M Mg2+
</span>[OH-] = .180 (3.52x10^-4) / .220+.180 = 1.58x10^-4 M OH-

Which reaction is a decomposition reaction?
Artist 52 [7]

Answer:

See the answer below , please.

Explanation:

In a decomposition reaction, a certain compound is "broken" to give two or more different products.

An example for compound AB, giving as products A and B:

AB -> A + B

In the case of water:

2H20 -> 2H2 + 02,  water decomposes giving Hydrogen and Oxygen
