How many grams of sulfur trioxide are produced 18 mol O2 react with sufficient sulfur? Show all your work S8 +12O 2> 8SO3

SOVA2 [1]

Answer:

$m_{SO_3}=2.31x10^4gSO_3$

Explanation:

Hello!

In this case, since the reaction between sulfur and oxygen is:

$S_8 +\frac{1}{2} O_2 \rightarrow 8SO_3$

Whereas there is a 1/2:8 mole ratio between oxygen and SO3, and we can compute the produced grams of product as shown below:

$m_{SO_3}=18molO_2*\frac{8molSO_3}{1/2molO_2} *\frac{80.06gSO_3}{1molSO_3} \\\\m_{SO_3}=23,057.3gSO_3=2.31x10^4gSO_3$

Best regards!

Write the ions present in a solution of na3po4. express your answers as chemical formulas separated by a comma. offset subscript

spin [16.1K]

Sodium/natrium is a metal from first column group so it should have one 1+ charge. Phosphate ion has 3- charge. That is why there 3 natrium ion for 1 phosphate ion when this molecule is dissolved in water. The ion formula would be:

(Na) $_{3}$ (PO $_{4}$ ) ==> 3 Na $^{1+}$ + PO $_{4} ^{3-}$

Which describes the molecule shown below?

lana [24]

Answer:

Option D. Saturated alkane

Explanation:

To know which option is correct, it is important that we know what saturated and unsaturated compounds are in this context.

Saturated hydrocarbons are compounds which has only carbon to carbon single bonds (C–C) in its chain. A very good example of such compound is the Alkanes.

Unsaturated hydrocarbons are compounds which has either a carbon to carbon double bond (C=C) or a carbon to carbon triple bond (C≡C) in its chain. Examples of such compounds include alkenes and alkynes.

Now, let us answer the question given above bearing the meaning of saturated and unsaturated compounds in mind.

The compound given above contains only carbon to carbon (C–C) single bond.

Therefore, the compound is a saturated alkane.

Ben is pushing a small trolley 10 N to the north and but Gary is pushing the trolley 5 N to the south. What is the total applied

andrew-mc [135]

Answer:

The total applied force on the trolley is 5 N toward the North.

Explanation:

In this problem, Ben is pushing the trolley to north and Gary is pushing it to south. So both the forces are acting 180° opposite to each other. As force is a vector quantity, the net force or total force acting on any object should be calculated by vector addition of number of forces along with their directions. So in this case, if we consider the force Ben is applying as F1 and the force Gary is applying as F2 on the trolley. Then the net or total force acting on the trolley will be $F1-F2$ . This is because, F1 and F2 are acting opposite to each other in direction.Thus, $Total force acting on the trolley = 10 N - 5 N$ .

So the total force acting on the trolley is 5 N and it is toward the north direction.
