Answers

Answer:

The answer Is B!

Explanation:

...............

To see the number of atoms of an element in a given molecule we need to multiply stoichiometry to the number that is written on the foot of the element that is stoichiometry. The correct option is option B.

What is atom?

Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit.

In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge. Neutron is neutral that is it has no charge. So overall the charge of nucleus is due to only proton, not by neutron. The number of atoms in a grapefruit would be equivalent to the number of blueberries in the house.

You and your friends decide to travel, on foot, to your favorite beach at the Jersey Shore. Your speed for the first part of the trip is 2.2 mi/hr. Twenty-three minutes after starting your trip, the group decides to stop at a convenience store for a drink. After stopping at the convenience store for five minutes, you continue your travels for 0.9 hour and then stop at a local fast-food restaurant for a bite to eat. You spend 20 minutes eating your favorite burger and 480 seconds after continuing your journey, you stop to use the restroom for 0.5 hr. Now that everyone feels a little lighter, the group increases its speed to 5.5 km/hr and spends the next 900,000 milliseconds traveling to a friend’s beach house to get sun block. After spending five minutes getting the sun block and raiding your friend’s pantry for snacks, the group starts “fist-pumping” in anticipation of their arrival at the beach. Eleven minutes and twenty five seconds later, you and your friends finally feel the warm sand beneath your feet. Approximately how many miles away is the beach?
