Answer:

A) C3H4

Explanation:

We have to remember that for each c<u>arbon we must have 4 bonds</u>. In a three-carbon alkene we will have 2 bonds for the <u>left carbon</u>, 4 bonds for the<u> central carbon</u> and 2 bonds for the <u>right carbon</u> (Figure 1). Therefore we have to add <u>2 hydrogens in the left carbon and 2 hydrogens for the right carbon</u>. Finally, if we count the number of carbons and hydrogens we will get C3H4.

If 40.0 g of HCl react with an excess of magnesium metal, what is the theoretical yield of hydrogen?
mamaluj [8]
Balanced equation: Mg+2HCl=MgCl2 + H2
Showing that if Mg is not a limiting factor then 2 moles of HCl on complete reaction liberate 1 mole of Hydrogen
therefore:
1 mole of HCl=35.5g, 40g=x
X= 40/35.5= 1.127mole
2 moles of HCl = 1 moles of Hydrogen
1.127=X
X=1.127/2 = 0.56
the theoretical yield of hydrogen

Answer : 4.8 florins can you exchange for your 4 guilders.

Solution : Given,

The current exchange rate for every 2.4 florins is 2.0 guilders

As per question,

The exchange rate is 2.0 guilders for every 2.4 florins

The exchange rate is 1 guilders for every \frac{2.4}{2.0} florins

The exchange rate is 4 guilders for every \frac{2.4}{2.0}\times 4=4.8 florins

Therefore, the 4.8 florins can you exchange for your 4 guilders.

Why are plastic containers preferred to glass containers for storing chemicals in the laboratory?
Nookie1986 [14]
Plastics are non-corrosive and non-reactive in nature. So they are used for storing chemicals in the laboratory. They are used for strong chemicals because they do not react with chemicals neither do they corrode
