Given: 4na + o2 → 2na2o in this chemical reaction, how many moles of na2o will be produced if 2.90 moles of na react completely? express your answer to three significant figures. there will be moles of na2o.

1.45 moles of

Explanation:

According to the stoichiometry:

Given : Na react completely, thus sodium is a limiting reagent as it limits the formation of product. Oxygen will be excess reagent as it does not react completely.

4 moles of sodium produce 2 moles of

Thus 2.90 moles of sodium produce = moles of

Thus 1.45 moles of will be produced.

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.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
