Hello!

When finding the chemical formula of a compound, we will need to find the charges of each element/bond.

Looking at our period table, sodium has a +1 charge, written as Na 1+, and sulfate has a charge of -2, and it is written as SO4 2-.

Now, we need to make the charges equivalent. To do this, we need to "criss-cross" the charges. This means that sodium will need to additional atoms to make the charges equal, and sulfate will need one.

Therefore, the chemical formula for sodium sulfate is: Na2SO4.

What weight of sodium hydroxide will react with 73 gram of hydrogen chloride gas at NTP to Produce 117.0 gram of Nacl and 36 gra

Wewaii [24]

Let's write the equation

$\\ \sf\longmapsto {NaOH\atop ?}+{HCl\atop 73g}\longrightarrow {NaCl\atop 117g}+{H_2O\atop 36g}$

According to law of conservation of mass .

Mass of products=Mass of reactants

Let required value be x

$\\ \sf\longmapsto x+73=117+36$

$\\ \sf\longmapsto x+73=153$

$\\ \sf\longmapsto x=153-73$

$\\ \sf\longmapsto x=80g$

How do you know if a chemical reaction is balanced ?

Alenkasestr [34]

Hey there!

We know that a chemical reaction is balanced when there is the same amount of each element on both sides of the equation.

According to the law of conservation of mass, matter cannot be created or destroyed, so we must have the same amount of each element on each side of a chemical equation.

We count the amount of each element on each side, and the products should have the same number as the reactants.

Hope this helps!

An example of a secondary alcohol is *

mojhsa [17]

Answer:

The answer to your question is the letter B

Explanation:

I will draw the skeletal structures of these compounds to determine which alcohol is secondary.

Secondary alcohol is alcohol in which the hydroxyl group is attached to a secondary alcohol.

Letter A has primary and secondary alcohol so I discard this choice.

Letter B has secondary alcohol, so this is the correct choice.

The letter C has a primary and 2 secondary alcohols so I discard this choice.
