You used 300 grams of Na2CO3 to wash one load of laundry. How many moles of laundry detergent did you use?

Chemistry

Answer: The number of moles of laundry detergent used is, 2.83 moles.

Explanation : Given,

Mass of Na_2CO_3 = 300 g

Molar mass of Na_2CO_3 = 106 g/mol

Formula used :

\text{Moles of }Na_2CO_3=\frac{\text{Given mass }Na_2CO_3}{\text{Molar mass }Na_2CO_3}

Now put all the given values in this formula, we get:

\text{Moles of }Na_2CO_3=\frac{300g}{106g/mol}

\text{Moles of }Na_2CO_3=2.83mol

Therefore, the number of moles of laundry detergent used is, 2.83 moles.

A chemistry student combines 23.0 grams of sodium and 71.0 grams of chloride to form sodium chloride. According to the law of co
Diano4ka-milaya [45]

Answer:

94.0 g.

Explanation:

Hello!

In this case, since the lay of conservation of mass states that energy cannot be neither created nor destroyed, during a chemical reaction it is seen that the reactions undergo a change by which bonds can be broken or formed depending on the case. Thus, for the formation of sodium chloride we evidence the formation of the Na-Cl bond which means sodium is combined with chlorine according to the following chemical reaction:

2Na(s)+Cl_2(g)\rightarrow 2NaCl(s)

It means that the reuslting mass of product is:

m_{NaCl}=23.0+71.0g=94.0g

Best regards!

Write the structure of the following compound:<br>=&gt; 3-(4-chlorophenyl)-2-methylpropane
Rudiy27

Answer:

See explanation and image attached

Explanation:

The IUPAC system of nomenclature enables the structure of molecules to be written seamlessly from the name of the compound. Hence it is commonly called the systematic nomenclature.

The parent chain here is propane. It is substituted at the 2- position by a methyl group and at the 3-position by 4-chlorophenyl group as we can see in the image attached to this answer.

You are balancing an ionic compound. Let's call it: AB.
rewona [7]

Answer:- A_3B_2

Explanations:- It is given that the charge for A is +2 and the charge for B is -3. The over all compound is neutral means the over all charge is zero. For making the over all charge zero, we need 3 positive ions and 2 negative ions. This makes a +6 charge for A and -6 charge for B and the over all charge is zero.

Also, if we think about the criss cross then charge of A becomes the subscript of B and the charge of B becomes the subscript of A.

So, the formula of the ionic compound is A_3B_2 . In this compound the ratio of A to B is 3:2.

The balanced equation could be shown as:

3A+2B\rightarrow A_3B_2

If a frog initially contained 2 grams of carbon-14 and the half-life of carbon-14 is 5,730 years, how much carbon-14 remains in
andreyandreev [35.5K]
Half life is the time taken for a radioactive isotope to decay by half its original mass. In this case the half life of carbon-14 is 5.730 years. 
Using the formula;
New mass = original mass × (1/2)^n; where n is the number of half lives (in this case n=1 ) 
New mass = 2 g × (1/2)^1     
                  = 1 g
Therefore; the mass of carbon-14 that remains will be 1 g
