Answer:
"a chemical reaction in which acid and a base react quantitatively with each other"
Explanation:
C) This model describes the dissemination of electrons in protons as analogous to figs in the cooked plum pudding batter.
Answer:
it is none of them here is how photosynthesis
Explanation:
the plant takes water, light energy, and carbon dioxide
then the plant makes sugar(also the sugar is called glucose) and oxygen and the oxygen leave the plant that is how photosynthesis work and if animals make carbon dioxide then to resive oxygen then they need to plant a plant seen and wait for multiple days
Answer:PH2=0.994atm, mass of zinc=0.606g
Explanation:
Equation for the reaction is written as;
Zn(s) + 2HCl(aq) - ZnCl2(aq) + H2(g)
V= 240ml = 0.240L
T= 30.8oC = 303.8K
Ptotal= 1.036atm
Pwater = 32mmHg at 30oC = 0.042atm
Therefore
PH2 = Ptotal - Pwater
= 1.036-0.042atm
=0.994atm
But PV= nRT
n = PV/RT
= 0.994x0.240/0.0821x303.8
= 0.24/24.94
=0.009324moles
For the grams of zinc
n=mass in grams/molar mass
Mass in grams = no of moles x molar mass
=0.009324x65 = 0.606g
