Answer : The volume of gas needed are, 90 L
Explanation : Given,
Volume of = 60 L
Now we have to determine the volume of needed.
As we know that at STP, 1 mole of gas contains 22.4 L volume of gas.
The given balanced chemical reaction is:
By the stoichiometry we can say that, 2 moles of react with 3 moles of oxygen gas to give 2 moles of gas and 2 moles of water vapor.
From the balanced reaction we conclude that,
As, volume of react with volume of gas
So, volume of react with volume of gas
Thus, the volume of gas needed are, 90 L
Answer:
i believe u mean "ionically". Yes it is.
Explanation:
Answer:
2.52kg
Explanation:
80mm = 8 cm
0.15m = 15 cm
volume of the container = 10m × 8cm × 15cm
= 1200 cubic centimetres
mass = density × volume
= 2.1 × 1200
= 2520g
2520/ 1000
= 2.52kilograms
Answer:
C
Explanation:
that's really the only one that makes any sence
Given that acids burns and the reactions of some metals with acids are violent, you have to protect agains spills and splashes that can seriously harm you: your eyes, your hands, your arms, your feet, even your clothe.
So you shall use:
- Safety glasses (googles)
- Chemical gloves
- Lab coat
- Closed shoes
