Answer:
0.16mole
Explanation:
To solve this problem, we are going to assume that the number of moles of carbon to be determined is that at STP, standard temperature and pressure.
The number of moles of a substance at STP is given as;
Number of moles = 
Given volume = 3.5L
Now, insert the parameters;
Number of moles = 
= 0.16mole
<span>Molar mass is the mass of
one mole of a substance, it can be a chemical element or a compound. It is a
characteristic of each pure substance. We calculate it by adding up all of the masses of the atoms involved in the compound. We calculate as follows:
atomic mass total mass
C 17 12.01 g/mol 204.17 g/mol
H 19 1.01 g/mol 19.19 g/mol
N 1 14.00 g/mol 14.00 g/mol
O 3 16.00 g/mol 48.00 g/mol
------------------------------------------------------------
Molar mass = 285.36 g/mol
</span><span>What is the mass of 6.02 x 10^24 molecules of morphine?
</span>6.02 x 10^24 molecules ( 1 mol / 6.02x10^23 molecules) ( 285.36 g/mol) = 2853.6 g morphine
That would be a catalyst, it makes the reaction faster.
Answer:
2HCl(aq)+K2CO3(aq)→H2O(l)+CO2(g)+2KCl(aq)
Explanation:
HCl(aq)+K2CO3(aq)→H2O(l)+CO2(g)+KCl(aq)
2HCl(aq)+K2CO3(aq)→H2O(l)+CO2(g)+2KCl(aq)
H-1*2=2 H-2
Cl-1*2=2 Cl- 1*2=2
K -2 K-1*2=2
C- 1 C-1
O - 3 O-3
