Answer:
16.5 dm³
Explanation:
Data Given:
no. moles of O₂ = 0.735 moles
volume of O₂ = ?
Solution:
Now
we have to find volume of O₂ gas
Formula used for this purpose
No. of moles = Volume / molar volume
where
molar volume at STP for Oxygen (O₂) = 22.4 dm³/mol
No. of moles O₂ = Volume of O₂ / 22.4 dm³/mol . . . . . .(1)
Put values in equation 1
0.735 = Volume of O₂ / 22.4 dm³/ mol
rearrange above equation
Volume of O₂ = 0.735 x 22.4 dm³/ mol
Volume of O₂ = 16.5 dm³
So,
the volume of O₂ at STP is 16.5 dm³

what is different about these two different foxes is the fox in Florida looks like he is on a diet of plants. The fox in wyoming looks like he has a squirel or some kind of animal in his mouth. Also their environment that they live in is completely different from each other hope it helps
Explanation:
Hello!
In an endothermic reaction, The potential energy of the products is greater than the potential energy of the reactants.
Any chemical reaction that absorbs energy is called an Endothermic Reaction. In this reactions, the reactants absorb energy from the surroundings to carry out the reaction. As a result, the products have a higher potential energy than the reactants. Photosynthesis is an example of an Endothermic Reaction, as the plant uses energy from the sun to generate the products.
Have a nice day!
