Answer:
Steam always has more thermal energy than ice.
Explanation:
<u>Answer:</u>
• 7.64 g Bi = 2.20 x 10²² atoms
• 35.8 g P = 6.95 x 10²³ atoms
<u>Explanation:</u>
First calculate the number of moles in each sample:
no. of moles = mass ÷ molar mass (RMM)
• 7.64 g Bi = 7.64 ÷ 209
= 0.03656 mol
• 35.8 g P = 35.8 ÷ 31
= 1.155 mol
Then multiply the number of moles by Avogadro's constant (6.02x10²³):
• 0.03656 x 6.02x10²³ = 2.20 x 10²² atoms
• 1.155 x 6.02x10²³ = 6.95 x 10²³ atoms
Answer:
B. Are c considered plants or animals?
Explanation:
The question that will be asked to show the problems associated with this type of model is the position of bacteria in the model because bacteria are neither animals nor plants and have a completely different system.
Bacteria are single-celled while plants and animals are multicellular. Bacteria are prokaryotic so they also lack nucleus and do not have any membrane-bound organelles while plant and animals cell have.
Hence, the correct option is "B. Are c considered plants or animals?".
