How many grams of CO2 would be formed by 33.7g of limestone with 100 mL of 0.1M HCl?

Question

Thanks in advance... any explanation would be helpful.

Kinda wondering on how to use HCI

Answer 1

CaCO3+2HCl---->CaCl2+H2O+CO2

(i guess you probably didn't know where does the CO2 come from. well, the reaction would have been CaCO3+HCl--->CaCl+H2CO3, but H2CO3 is one of the least powerful acids, and when it's a reaction product it decompounds into H2O and CO2. think about it, H2CO3 is soda, that is water +carbon dioxide.)

100ml=0,1 l; M HCL=1+35,5=36,5;
cM=n/V;
n=m/M;
=> cM=m/M*V
=>m=cM*M*V=0,1*36,5*0,1=0,365 grams of HCl

as you can now see, there is an excess of CaCO3 (33,7 g of CaCO3 while only 0.365 g of HCl), so you will calculate the amount of CO2 according to the amount of HCl.

M CO2=12+2*16=12+32=44

.................0,365..................................x
CaCO3 + 2HCl---> CaCl2 + H2O + CO2
................2* 36,5...............................44

x=0,365*44/2*36,5=0,22 grams of CO2


i hope i could help:)

Answer 2

first we must write down a balanced equation for that reaction so
Limestone+ Acid ----> Salt +H2O +CO2
CaCO3 + 2HCl -----> CaCl2 +H2O + CO2
1mole +2 moles ---> 1 mole + 1 mole +1 mole
100 g + 73 g -----> 111 g + 18 g + 44 g
but in your reaction we dont have 100 g CaCO3 and the 100 ml of 0.1 cant give a complete reaction ,, so we need to measure how many grams of HCl,
33.7 g / 100g =0.3 mole of CaCO3
Wt of HCl = molarity xM.Wtx volume/1000
Wt of HCl= 0.1 x 36.5 x100/1000=0.365 g

Answer 3

for every one mole of HCL, 1 mole of limestone is going to be converted into one mole of CO2 (assuming its a 1:1:1 ratio in the balanced chemical equation, i dont feel like writing it out), then calculate the number of moles of HCL that are going to be used (looks like you have .01 moles of HCL [.1 molar times .1 liters]), and from there, convert that to moles of CO2 (which is a 1:1 ratio IIRC), so you have .01 moles of CO2. then convert those moles to Grams, which is .01 moles*(12+16x2 for the atomic masses of carbon and oxygen), and you get .44 grams of CO2 it seems.

Answer 4

you'd get about 45gms. i'm sorry but the definitive answer is done and gone
