Using the values of standard enthalpy of formation NH3 = -46.19 KJ/mol

N2H4 = 95.40 KJ/mol

H2O = -285.83 KJ/mol

determine the standard enthalpy of formation for the reaction

4NH3 + O2 --> 2 N2H4 + 2 H2O

the sum of reactants is KJ/mol

the sum of products is KJ/mol

The heat of formation is KJ/mol

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of c is as shown here in the image.

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.

i think so it’s will be b yes i believe its
