Astudent in lab combined 41.514 g of 1.0 m hcl solution (d = 1.0 g/ml) with 51.158 g of 1.0 m naoh solution (d = 1.0 g/ml) in a coffee cup calorimeter and recorded the temperature data below. calculate the enthalpy change (∆ ° ) per mole of hcl. (assume the specific heat capacity of the solution is the same as water, 4.184 j/g‧k.) hcl(aq) + naoh(aq) → h2o(l) + nacl(aq)

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
