Compare a subscript with a coefficient

Chemistry
1 answer:
zhuklara [117]4 years ago
7 0
A subscript usually applies to the number of molecules of a single element. A coefficient applies to the whole compound. For example, CO2, there are 2 oxygen molecules. But if it were 4NaCl, that's 4 molecules of salt. Each molecule containing only 1 of each element.

If the molar mass of calcium hydroxide (Ca(OH)2) is 74.1 g/mol, how many grams of calcium hydroxide are required to prepare 2.00
Llana [10]

Answer:

88.92 grams of Ca(OH)₂ are required

Explanation:

Molarity means mol/L, so 0.6 M are the moles of solute in 1 L of solution.

In 2 L, we 'll have the double of moles, 1.2

Mol . molar mass = grams

1.2 mol . 74.1 g/m = 88.92 grams of solute

HELP.....From the information presented in the activity series of metals below (4 metals included), answer the following questio
san4es73 [151]

Answer:

a)there would be no reaction

Explanation:

The activity series of metals has many functions. The one applicable to this problem is that it can be used to determine whether a reaction will occur or not. Also, based on the positions of metals in the series, we can know how reactive a metal is compared to another.

In a single displacement reaction, a metal replaces another metal based on their position on the activity series. Metals that are higher in the series are generally more reactive than others below them and so will displace them.

 

Would aluminum replace magnesium to form a new compound or would there be no reaction?

Magnesium is higher than aluminum in the activity series. Therefore it is more reactive than aluminum. No reaction will occur.

zzz [600]
I think the answer is Aluminium is oxidized from 0 to +3. A half reaction is a reduction or oxidation reaction component of a redox reaction. It is got by considering the change in oxidation states of independent substances involved in a redox reaction.
