Answer:
14g
Explanation:
N2 + 2O2 => 2 NO2
Molar mass of O2 = 32g/mol
No of mol= 16/32 = 0.5 mol
2 moles of Oxygen react with 1 mol of N2
1 mol of oxygen react with X mol of N2
X = 0.5mol
Molar mass of N2 = 28g/mol
No of mol = mass/molar mass
Mass = 0.5 × 28 = 14g.
For example when the northern hemisphere is experiencing summer it is tilting toward the sun and the Southern Hemisphere is experiencing winter and is tilting away from the sun

Answer:
Explanation:
There are few simple rules in organic chemistry which a person must learn.
1. In predicting a structure from ozonolysis, number of oxygen present in products must be counted. In this particular example, there are 2+3+1 = 6 oxygen atoms are present in three molecules. This means that there should be at least three confirmed double bonds must be present in the molecule of Dictyopterene.
2. There are in total of 3+5+3 = 11 carbon atoms present, making 2^11 = 2048 possible structures for this particular structure. But since there are three double bonds present, this will reduce the number of possible structures as well.
3. Questions also says that when fully hydrogenated, the molecule generates Butylcycloheptane. That means that our base molecule is Butylcycloheptane and this molecule contains at least three double bonds.
So, first we draw the molecule of butylcycloheptane. After this, we think of were double bonds could be present. We do have the products. Let's make their structures first. I have also mentioned the possible breakup where the ozonolysis has occured by color code. You can see them in the reference image attached.
Part 1 out of 2: There is only one chiral carbon present in the molecule and have two possible isomers. Cis and Trans. Only one stereogenic carbon is present, that's why two possible isomers. Image attached.
Answer:
1.2 x 10²⁴ atoms
Explanation:
Given:
Number of moles of Ag = 2moles
Unknown is the number of atoms it contains:
Solution:
A mole of any substance is known to be made up of 6.02 x 10²³ atoms
Now;
2 moles of an atom will contain:
2 x 6.02 x 10²³ = 1.2 x 10²⁴ atoms
