What is the mass of one mole of popcorn kernels? (sig fig hint: consider the precision of avogadro's number to determine the cor
svetlana [45]

Since the mass of a single popcorn kernel is not given, lets us assume that it is 1 gram

Now:

1 mole of popcorn kernels contain 6.023 * 10^{23} kernels

Since:

1 kernel weighs 1 gram

Then,

1 mole = 6.023 *10^{23} kernels would weigh 6.023 * 10^{23} grams

Match each chemical reaction with the type of reaction that best describes it.
r-ruslan [8.4K]

2 Al + 6 HCl → 2 AlCl₃ + 3 H₂ (single displacement)

Ca + Br₂  → CaBr₂ (synthesis)

4 NH₃ + 5 O₂  → 4 NO + 6 H₂O (combustion)

2 NaCl → 2 Na + Cl₂ (decomposition)

FeS + 2 HCl → FeCl₂ + H₂S (double displacement)

single displacement - is a chemical reaction of the following type: A + BC → AC + B

double displacement - is a chemical reaction of the following type: AB + CD → AC + BD

synthesis - the chemical product is obtained by combining in a synthesis the constituent elements

combustion - usually a exothermic reaction of a particular compound with oxygen

decomposition - degradation of a compound in simpler elements

Compounds X and Y are both C6H13Cl compounds formed in the radical chlorination of 3-methylpentane. Both X and Y undergo base-pr
zubka84 [21]

Answer:

Y is a 3-chloro-3-methylpentane.

The structure is shown in the figure attached.

Explanation:

The radical chlorination of 3-methylpentane can lead to a tertiary substituted carbon (Y) and to a secondary one (X).

The E2 elimination mechanism, as shown in the figure, will happen with a simulyaneous attack from the base and elimination of the chlorine. This means that primary and secondary substracts undergo the E2 mechanism faster than tertiary substracts.
