When hydrogen ................................... a CIS formation exist.
There are two types of formation which are possible in fatty acids, these are CIS and TRANS configurations.
A fat is described as a CIS fatty acid if its hydrogen atoms are lying on the same side of the carbon carbon double bonds. A fat is said to be a trans fatty acid, if the hydrogen atoms in its molecules are lying on the opposite sides of the carbon bonds.
Covalent bonds form when electrons are shared between two nonmetals.
The empirical formula : Na₂Cr₂O₇

Given
170 g sample contains :
29.84 g sodium, 67.49 g chromium, and 72.67 g oxygen
Required
The compound's empirical formula
Solution
mol ratio of elements :
Na : 29.84 : 23 g/mol = 1.297
Cr : 67.49 : 51,9961 g/mol = 1.297
O : 72.67 : 16 g/mol = 4.54
Divide by 1.297
Na : Cr : O = 1 : 1 : 3.5 = 2 : 2 : 7
Answer:
A) 0.50 M
Explanation:
The computation of the number of molarity of the NaOH is given below:
As we know that
Molarity = Moles ÷ liters
where
Moles is 20
And, the liters is 40
So, the molarity is
= 20 ÷ 40
= 0.50 M
hence, the molarity of the NaOH solution is 0.50 M
Therefore the A option is correct
223.44 grams is the answer. Multiply 2.28 times the gram formula mass of h2so4
