Answer:
b). 0.732
Explanation:
52g Na₂SO₄ x 1 mol Na₂SO₄ x 2 mol Na
------------------------- -------------------- = 0.732 mol Na
142.04 g Na₂SO₄ 1 mol Na₂SO₄
Atomic Mass Units
Na₂ = 22.99 x 2 = 45.98
S = 32.06
O₄ = 16 x 4 = 64
Na₂SO₄ = 45.98 + 32.06 + 64 = 142.04
There are 2 moles of Na in 1 mole of Na₂SO₄
Answer:
Pulse rate depends on the activity we do, while exercising theres need of more oxygen so it increases but while at rest body requires less oxygen so low pulse rate.
Explanation:
The given molecule is
H3C - C ≡ C - CH3
The numbering order is shown below:
H3C - C ≡ C - CH3
1 2 3 4
So, the alkyne group is in the second position.
The carbon chain has four carbons.
Hence, the IUPAC name of the given compound is:
2-butyne.
Answer:
The answer to your question is below
Explanation:
Process
1.- To draw an organic molecule, start from the end of the name (pentane)
Pentane has 5 carbons.
2.- Assign numbers the carbons, you can start from the left or to the right
3.- Attach the branches (bromine) in positions 2 and 3
