Answer:

Breathing air with a high concentration of CO reduces the amount of oxygen that can be transported in the blood stream to critical organs like the heart and brain. At very high levels, which are possible indoors or in other enclosed environments, CO can cause dizziness, confusion, unconsciousness and death.

A scientist discovers a new type of polymer. What must be true about this polymer?

kolbaska11 [484]

This polymer must D. be made of large molecules with repeating units.

A polymer consists of long chains of smaller repeating units called <em>monomers</em>.

For example, <em>polyethylene</em> consists of long chains of ethylene (CH₂=CH₂) units joined together end to end.

The formula for polyethylene is -CH₂CH₂-(CH₂CH₂)ₙ-CH₂CH₂-, where n is usually a number between 500 and 10 000.

How many grams of aluminum chloride can be produced from 7.32g of ammonium perchlorate?

Alla [95]

Answer:

2.77g of $AlCl_{3}$ can be produced.

Explanation:

Use stoichiometry.

Balanced equation: $3Al + 3NH_{4} ClO_{4}$ ⇒ $Al_{2} O_{3} + AlCl_{3} +3NO + 6H_{2} O$

$NH_{4} ClO_{4} : AlCl_{3}$

3 : 1 ** $n=\frac{m}{M}$

0.0623** : $x$ $n=\frac{7.32}{117.49}$ = 0.0623

$3x=0.0623\\x=0.020767$

$n=\frac{m}{M}$

$m=nM$

m= (0.020767)(133.34)

m= 2.77g

In an experiment, two unknown compounds (one an alcohol and the other an ether) of equal molecular mass were dissolved in water.

-BARSIC- [3]

Answer: B. It is an ether because it is unable to to form a hydrogen bond, so it is less soluble than water

Explanation: Alcohols $(ROH)$ are more soluble in water as they can form hydrogen bonding with water whereas ethers $(ROR)$ are less soluble as they do not form hydrogen bonds with water.

For formation of hydrogen bond, the electronegative atom (F, Oand N) must be attached to hydrogen and in ethers (ROR), there is no hydrogen directly attached to electronegative oxygen atom, thus are less soluble in water.
