rodikova [14]
C. 50%
Unless the question is saying he only gets heads once, in which case it would be 0%. Or the coin could have 2 heads. Then it would be 100%.
But I'm pretty sure it's 50%.

How would you prepare 3.5 L of a 0.9M solution of KCl?
PolarNik [594]
V=3,5L\\
Cm=0,9M\\
M_{KCl}=74\frac{g}{mol}\\\\
C_{m}=\frac{n}{V}\\\\
n=\frac{m}{M}\\\\
C_{m}=\frac{m}{MV} \ \ \ \Rightarrow  \ \ \ m=C_{m}MV\\\\
m=0,9\grac{mol}{L}*74\frac{g}{mol}*3,5L=233,1g

B. Add 233 g of KCl to a 3.5 L container; then add enough water to dissolve the KCl and fill the container to the 3.5 L mark.

(a) What structural feature is associated with each type of hydrocarbon: alkane, cycloalkane, alkene, and alkyne?
Snowcat [4.5K]

Alkanes are hydrocarbons with straight, saturated branch chains. Ring-shaped hydrocarbons are cycloalkanes. Alkenes are branch chains that are straight and have at least one double bond. Alkynes are branch chains that are straight and have at least one triple bond.

<h3>What is Hydrocarbon ?</h3>

A hydrocarbon is an organic molecule in organic chemistry that is made completely of hydrogen and carbon. Examples of group 14 hydrides include hydrocarbons. The majority of hydrocarbons are colorless and hydrophobic, and their scents are either insignificant or best characterized by those of gasoline and lighter fluid.

Other side effects from certain hydrocarbons include coma, seizures, abnormal cardiac rhythms, and liver or kidney damage. Some solvents used in paints, dry cleaning, and household cleaning solutions are examples of items that contain hazardous hydrocarbons.
