Answer:

C) 4moles

Explanation:

Let's consider the following balanced equation.

2 H₂S(g) + 3 O₂(g) → 2 SO₂(g) + 2 H₂O(g)

The molar ratio of O₂(g) to SO₂(g) is 3:2. The moles of SO₂(g) produced from the reaction of 6 moles of O₂(g) are:

6 mol O₂(g) × (2 mol SO₂(g)/ 3 mol O₂(g)) = 4 mol SO₂(g)

When 6 moles of O₂(g) react with more than enough H₂S(g), 4 moles of SO₂(g) are produced.

The balanced equation is expressed:

<span>H2S + 3/2O2 --> SO2 + H2O 
</span>
We are given the amount of O2 to be used in the reaction. This will be the starting point for our calculations. We do as follows:

6 mol O2 ( 1 mol SO2 / 3/2 mol O2 ) = 4 moles SO2 produced

Hope this answers the question. Have a nice day.

Sophie [7]
You would know that the variable is quantitative if it shows any number to express the quantity. For example, quantitative variables are 50°C, 5 atm, 2 moles, 100 L and so on. A variable is qualitative if it expresses a relative quantity but not expressing a number. Examples would be: few, too hot, several, or even describing the characteristics of a variable. Hence, when the variable is in grams, then that would be quantitative.

How do cells respond to contact with other cells?
Blababa [14]
It depends on the function and activity of both cells. Most normal cells crease division if they came into contact with other cells however the immune system interact directly with pathogens or foreign organisms to destroy them.

Answer: P_4(l)+5O_2(g)+3H_2O(l)\rightarrow 2H_3PO_4(l)  

Explanation:

We are given two reactions which are the two steps of a mechanism:

P_4(l)+5O_2(g)\rightarrow 2P_2O_5(g)       ......(1)

P_2O_5(g)+3H_2O(l)\rightarrow 2H_3PO_4(l)        .......(2)

To determine the net chemical equation, we will multiply equation 2

P_2O_5(g)+3H_2O(l)\rightarrow 2H_3PO_4(l)\times 2  

2P_2O_5(g)+6H_2O(l)\rightarrow 4H_3PO_4(l) .......(3)

Adding (1) and (3)

P_4(l)+5O_2(g)+3H_2O(l)\rightarrow 4H_3PO_4(l)  

Thus, the net balanced chemical equation is:

P_4(l)+5O_2(g)+3H_2O(l)\rightarrow 4H_3PO_4(l)

puteri [66]

Answer:

8. A boat, cars, airplanes

9. It's safer to practice techniques on life sized models of human organs than practicing on an actual human. If you mess up on a model it doesn't matter, messing up on a human can put their life at risk.
