Ent will For each of the following atoms, write the electron configuration, referring to
the periodic table. Then write the formula of the ion the atom is most likely to
form and identify that ion as a cation or an anion. Finally, write the electron
configuration of the ion.
1. bromine (Br), element 35
2. gallium (Ga), element 31
3. sulfur (S), element 16
4. rubidium (Rb), element 37
Write the electron con

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).

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
