I have a balloon that can hold 59ol of ai. If I blow this balloon up with 8.37mol025 at a pressure of 4.079atm. calculate the temperature of in kelvin.
3500k
write chemical equation (ce) base on description.
solid magnesium combines with gas house oxygen to yield solid magnesium oxide
Mg(s)+O2(g)->Mg+2O-2=MgO(s)
calculate mole CO2 produced when 7.480mol O2 react.
4.603molCO2
Culate [H+1] in an aqueous solution with pH=549
=3.2*10-6m
where do oceans take CO2 from?
From the atmosphere
if I have a canister that holds 6.27mol of gas at a pressure of 4.08atm and a temperature of 9.356*c. calculate the volume.
N=6.27mol
P=4.08atm
T=9.356*c
V=?
=1.210L
Gaseous tricarbon octahydride mixes with at gas to form water vapor plus gases carbon dioxide.
C3H8(g)+O2(g)->H2O(2)+CO2(g)
Calculate the #mol RB3PO4 needed to produced 6.43mol RbCl.
2.14mol Rb3PO4
calculate [OH-1] in a aqueous solution with poH=13.26
=1.5*10-11m
Oceans are responsible for absorbing how much CO2?
More than 1/3 of CO2
in a hydradyn bond of OH why does O have an S and HaS+.
O has S- because it has ^ electron gravity and pulls ve- towards it.
add coefficients to balance
-Fe(s)+2 Cu2SO4(aq)-4 Cu(s)=-Fe(sO4)2 (aq)
Contrast the limiting reactant (LR) and excess reactant (ER)
LR= restricts amount of product
ER= doesn't not restrict
Calculate [OH-1] in a solution with poH=4.67
=2.110-5m
what are the 3 process of CO2
Fossil fuel burning, deforestation, cement production
Explain law of conservation of mass.
It has S+ bc it has v and en and ve- pulls away from it.
Write BCE Based on UBCE
Mg(aq) + 2NO3-1(aq)+Pb+2(aq)+SO4-2
Explain what happens once the LR is used up
Chemical Rxn stops
Calculate [H+1] in a solution with pH =10.83
1.5*10-11m
in ocean water becoming less neutral
convert the pressure from 260.38kpa to psi.
37.73psi
Classify chemical reaction type
_C6H12(g)+_O2(g)->_CO2(g)+6H2O(g)
Combustion becauseCo2+H2O are products
calculate #mol available of C2H4 and O2 if 8.32g C2H4 and 7.69g O2 are used
8.32/28.06=0.297molC2H4
7.69/32.00=0.240molO2
A group of sea nails
What does ocean acidification not imply.
does not imply ocean water will become acidic
