Answer:
V = 38.48 L
Explanation:
Given that,
No. of moles = 1.5 mol
Pressure, P = 700 torr
Temperature, T = 15°C = 288 K
We need to find the volume of the gas. The ideal gas equation is given by :
, R = L.Torr.K⁻¹.mol⁻¹
So, the required volume is equal to 38.48 L.
<u>Answer:</u>
The velocity of the bus be is 0 miles/second
<u>Explanation:</u>
Given, a bus travelled a distance of 20 miles north and 20 miles back to the starting point
Hence, total distance = 20 + 20 = 40 miles
Velocity is calculated by the formula:
Velocity = 
Displacement = 
Velocity = 
Therefore, the velocity of the bus is 0 miles/second
Answer:
The first option, aka Opick it up off the gound within 10 seconds, and it's o.k. to eat
Explanation:
The 10 second rule is a rule when you drop foods, but if you get it off the floor under 10 seconds, you can eat it.
Did you know that food picked up under 10 seconds and after 10 seconds has almost the same number of bacterias? The 10 second rule is basically worthless.
<u>Correct Answer:</u><u> Option (A) </u>
H₂S : SO₂ = 2:2 and,
O₂: H₂O = 3:2
Explanation:
The mole ratio is the ratio of coefficients of the compounds involved in the reaction. <u>R</u><u><em>eactants,</em></u><u> as on the left hand side of the chemical reaction which reach to for</u>m new products.
In the given reaction,
2H₂S + 3O₂ ⇒ 2SO₂ + 2H₂O
<u>The reactants are :</u> H₂S (hydrogen sulphide) & O₂ (oxygen)
<u>The products are :</u> SO₂ (sulphur dioxide) & H₂O (water)
- 2 moles of hydrogen sulphide react with 3 moles of oxygen
- 2 moles of sulphur dioxide & 2 moles of water are produced
Therefore correct option is
H₂S : SO₂ = 2:2 and,
O₂: H₂O = 3:2
