what coefficients would be needed to balance the following chemical equation? put them in order separated by commas. if no coefficient is needed, put a 1. example: 1,2,3,4

a) 2, 1, 1
b) 1, 2, 1
c) 1, 1, 2
d) no coefficients needed

it is a good conductor

explanation:

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

answer : third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

explanation :

let us write down the given equations

equation 1 :

equation 2 :

equation 3 :

let us use hess's law to find out which 2 equations can be added to get the third equation.

let us reverse equation 2 and multiply it by 2. the new equation that we get is,

equation 4 :

let us add equation 1 & 4

the above equation is similar to equation 3 but has different value for dhrxn.

therefore third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

c. orbital shape i hope this is correct
