Answer;
They indicate the acidity level. That is, the less pH, the more acidic
Hope it helps :)
Find the molar mass of Fe_2O_3
2Fe = 2*56 = 112
3O = 3* 16 = 48
Molar Mass = 160 grams
moles= given mass / molar mass
moles = 28 / 160
moles = 0.175 <<<< answer
The objects that are rubbed together will create charges among themselves due to friction.
(1) The balloon rubbed with a wool cloth will be charged.
(2) If she comb near a small, uncharged object nothing will change.
(3) This is a scientific investigation because it does not involved a step by step process to answer a scientific query.
The answer to this question would be: the anion uptake will be decreased
If proton pump function is decreased, that means the amount of proton that goes outside the cell will be decreased. It will cause the anion uptake decreased too because some anion needs to go inside cells by co transporting with the proton.
