Explanation:
Not Many
1 mol of CO has a mass of
C = 12
O = 16
1 mol = 28 grams.
1 mol of molecules = 6.02 * 10^23
x mol of molecules = 3.14 * 10^15 Cross multiply
6.02*10^23 x = 1 * 3.14 * 10^15 Divide by 6.02*10^23
x = 3.14*10^15 / 6.02*10^23
x = 0.000000005 mols
x = 5*10^-9
1 mol of CO has a mass of 28
5*10^-9 mol of CO has a mass of x Cross Multiply
x = 5 * 10^-9 * 28
x = 1.46 * 10^-7 grams
Answer: there are 1.46 * 10-7 grams of CO if only 3.14 * 10^15 molecules are in the sample
Answer:
Many years ago, people living on the Earth, desired to go to the outer space.
Explanation:
When man initiate to go outer space:
Many times ago, people used to think about the world out of Earth, the space and the sky. These thoughts generated the idea of thinking and imagining the space and the moon.
The idea turned into a movie by Georges Méliès, which was inspired by a book written by Jules Verne. The movie gave the idea to Konstantin Tsiolkovsky, a Russian man to develop many ideas which were implemented by Russia and America to build airplanes and rockets that we see launching at present.
A small though became an idea which gave birth to a new invention through which people live their dreams of going in the outer space. Incredible!
Answer:
There are 2 types of forces, contact forces and act at a distance force. Every day you are using forces. Force is basically push and pull. When you push and pull you are applying a force to an object.
Explanation:
Answer:
Ionization energy, electronegativity, and lattice energy are the factors that influence the formation of ionic bonds of elements.
Explanation:
Net ionic between HCl and the buffer equation
CH3COOH --> acetic acid, CH3COO- acetate , H+ proton from HCl
there is neutralization of the acetate, and an increase in acid
the ionic equation
CH3COO-(aq) + H+(aq) + Cl-(aq) --> CH3COOH(aq) + Cl-(aq)
Net ionic:
CH3COO-(aq) + H+(aq) --> CH3COOH(aq).
