1N2 + 2O­2 → 1N2O4

If 55.52 grams of N2O4 was produced, how many moles of O2 were required?

Explanation:

Hello there!

In this case, according to the given chemical reaction, it possible to calculate the required moles of oxygen by firstly knowing that the molar mass of N2O4 which is 92.011 g/mol and the mole ratio of that product to oxygen is 1:2; in such a way, we proceed as follows:

Regards!

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
