Answer:
There is one single covalent bond between two carbon atoms.
Explanation:
We know that sharing of electrons form covalent bonds.
If we look upon K,L,M ,N shells of the carbon and hydrogen atoms.
We found that Hydrogen is having only
electron in K shell.
And Carbon on the other hand is having
electrons in K shell and
electrons in L shell.
So carbon have
valence electrons,and it can share
bonds with any relevant atom to complete its octet.
And Hydrogen requires
electron to complete its doublet.
Alkane general formula 
For ethane 

Carbon atom is shared by
Hydrogen.
The remaining one electron
of carbon will be shared with another carbon atom.
An image of the sharing of electrons attached below,
Hence we have only
covalent bond between the two.
It means “the study of.” Think of it:
Those are subjects you study. It makes more sense than the other choices.
Answer:
8 waffles
Explanation:
First, find the limiting reagent. Divide the amount you have by the amount that is needed. The smallest number is the limiting reagent. <u>For this problem, the limiting reagent is oil.</u>
6 cups of flour/2 cups of flour = 3
9 eggs/3 eggs = 3 2 tbsp of oil/1 tbsp of oil = 2
This means that we can double the recipe since we have enough of each ingredient to make two batches. Multiply the entire equation by 2. This should give you 4 cups of flour + 6 eggs + 2 tbsp of oil ==> 8 waffles.
<u>You should theoretically get 8 waffles.</u>
Answer: 0.85075J/g.K
Explanation:
Mass of the material = 100g
Energy (Q) = 5104.5J
T1 = 20°C = 293K
T2 = 80°C = 353K
Formula for heat energy (Q) = mc ∇T
Q = mc∇T
∇T = T2 - T1
∇T = 353K - 293K = 60K
Q = mc∇T
C = Q / m∇T
C = (5104.5) / (100 * 60)
C = 0.85075 J/gK
The specific heat capacity of the material is 0.85075J/gK.
It gives each organelle in the cell its own specific function
