I think the correct answer would be spontaneous oxidation-reduction reaction. The type of reaction in a voltaic cell is best described as a spontaneous oxidation-reduction reaction. A voltaic cell uses the energy from the chemical reaction involved to produce electrical energy. Hope this answers the question.
Indium has 49 protons
mass number (# of neutrons and # of protons combined) is 115
115 - 49 = 66
66 neutrons
Answer:
A oxygen
Explanation:
For plant growth nitrogen, potassium and phosphorous are the three main elements needed. oxygen is expelled from plants. Plants doesn't need oxygen
I am first assuming that you want the molarity of the acid. Use the formula
which is the titration formula. M is molarity (a is of acid and b is of base) and V is volume in mL (a is of acid and b is of base). Plugging in gives us
. Solving gives us
