If the standard reduction potential of a certain half-reaction is -0.30 V, which statement below is TRUE for this half-reaction to proceed as a reduction?a. This half-reaction will proceed if it is coupled to another half-reaction that has a standard reduction potential less than 0.80 V. b. This half-reaction will proceed if it is coupled to another half-reaction that has a standard reduction potential greater than 0.80 V c. This half reaction will proceed if it is coupled to another half-reaction that has a standard reduction potential greater than -0.80 V d. It doesn't matter what half-reaction this is coupled with, it will proceed spontaneously. E) It doesn't matter what half-reaction this is coupled with, it will not proceed spontaneously.

the answer is a. co2, this would be colder than the : )

explanation:

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8  

mgco3-5h2o"

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
