Animal cells each have a centrosome and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, whereas animal cells do not.

1. Determine which object will SINK or FLOAT in water.

zubka84 [21]

Answer: Block # 1 , Block # 4 and

Block # 5 will sink.

Block # 2 and 3 will float.

Explanation: The density of water is equal to 1 g/mL. Any density that is less than the density of water will float. Objects with higher density compared to water will eventually sink.

In two to three sentences, explain the trend for atomic size. Why does this trend occur?

lutik1710 [3]

Answer:

The number of energy levels increases as you move down a group as the number of electrons increases. Each subsequent energy level is further from the nucleus than the last. Therefore, the atomic radius increases as the group and energy levels increase. 2) As you move across a period, atomic radius decreases.

if 66.38 g of potassium chloride reacts with fluorine and produces potassium fluoride and chlorine how many moles of chlorine ca

Ann [662]

Taking into account the reaction stoichiometry, f 66.38 g of potassium chloride reacts with fluorine and produces potassium fluoride and chlorine, 0.4452 moles of chlorine is produced.

<h3>Reaction stoichiometry</h3>

In first place, the balanced reaction is:

2 KCl + F₂ → 2 KF + Cl₂

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

KCl: 2 moles
F₂: 1 mole
KF: 2 moles
Cl₂: 1 mole

The molar mass of the compounds is:

KCl: 74.55 g/mole
F₂: 38 g/mole
KF: 58.1 g/mole
Cl₂: 70.9 g/mole

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

KCl: 2 moles ×74.55 g/mole= 149.1 grams
F₂: 1 mole ×38 g/mole= 38 grams
KF: 2 moles ×58.1 g/mole= 116.2 grams
Cl₂: 1 mole ×70.9 g/mole= 70.9 grams

<h3>Moles of Cl₂ formed</h3>

The following rule of three can be applied: if by reaction stoichiometry 149.1 grams of KCl form 1 mole of Cl₂, 66.38 grams of KCl form how many moles of Cl₂?

$amount of moles of Cl_{2} =\frac{66.38 grams of KClx1 mole of Cl_{2}}{149.1 grams of KCl}$
