Why are cells small?​

Answers

Answer 1
Answer: Because if a cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.
They are also small so they can maximize the ratio of surface area to volume. Smaller cells have a higher ratio which allows more molecules and ions move across the cell membrane per unit of cytoplasmic volume.

basically cells are small because they need to be able to get the nutrients in and waste out quickly.

What volume does 8.5 g NH₃ occupy at STP? a. 2.81 L
b. 5.61 L
c. 11.21 L
d. 22.41 L
e. 44.81 L

Answers

First, convert grams to moles by dividing 8.5 by the molar mass of NH₃ (N=14,H=1)
14+1+1+1=17
8.5/17=.5 moles NH₃
Multiply .5 by the conversion factor of moles to L (22.4)
.5*22.4=11.2 L NH₃
11.2 is just 11.21 rounded down, so your answer is C) 11.21 L

What is the name of the ionic compound that contains a NA+ ion for every Cl- ion

Answers

The name is sodium chloride. This is an ionic compound so you use the ionic naming system which is the name of the cation followed by the name of the anion. I hope this helps. Let me know if anything is unclear.

A real gas behaves least like an ideal gas under the conditions of(1) low temperature and low pressure
(2) low temperature and high pressure
(3) high temperature and low pressure
(4) high temperature and high pressure

Answers

The correct answer is option 3. A real gas behaves least like an ideal gas under the conditions of high temperature and low pressure. At this temperature and pressure, the molecules are close to each other and collisions or interactions are very likely to happen which is not an ideal gas.

In an exothermic energy diagram, the reactants side is higher in energy than the product side.

What is an exothermic reaction?

An exothermic reaction is one in which the heat of the reactants is greater than that of the products. In that case, energy is given off in the reaction  as heat and the reaction vessel is warmer.

Now, in an exothermic energy diagram, the reactants side is higher in energy than the product side.
