Based on ecological studies, the definitions below applies to the given terms:

  • Peak phenomena: this is when a population grows at a fast rate, then quickly drops when the resources run out
  • Biological surplus: this occurs when there are more organisms in a population than the ecosystem can sustain
  • Climax community: this is a point in an ecosystem when all populations reach a point of little or no change
  • Sigmoid phenomena: this is when a population increases while food and habitat are abundant and decreases as food becomes less available

<h3>What is ecology and what are some terms in ecology?</h3>

Ecology is the study of living things and their interactions with their environment.

Some terms in ecology include:

  • Peak phenomena: this is when a population grows at a fast rate, then quickly drops when the resources run out
  • Biological surplus: this occurs when there are more organisms in a population than the ecosystem can sustain
  • Climax community: this is a point in an ecosystem when all populations reach a point of little or no change
  • Sigmoid phenomena: this is when a population increases while food and habitat are abundant and decreases as food becomes less available

Find mass of 4.5 moles of co2​
Kobotan [32]

Answer:

198g

Explanation:

Molar Mass of CO2 = 12 + (2x16) = 12 + 32 = 44g/mol

Number of mole of CO2 = 4.5moles

Mass of CO2 =?

Mass = number of mole x molar Mass

Mass of CO2 = 4.5 x 44 = 198g

Hydrochloric acid reacts with sodium hydroxide to produce sodium chloride and water. If 20.6 g of sodium hydroxide reacts with a
astraxan [27]

Answer:

30.1 g NaCl

Explanation:

Your first conversion is converting grams NaOH to moles of NaOH using its molar mass (39.997 g/mol). Then, use the mole ratio of 1 mol NaCl for every 1 mol NaOH to get to moles of NaCl. Then finally multiply by the molar mass of NaCl (58.44 g/mol) to get grams of NaCl.

20.6 g NaOH • (1 mol NaOH / 39.997 g NaOH) • (1 mol NaCl / 1 mol NaOH) • (58.44 g NaCl / 1 mol NaCl) = 30.1 g NaCl

What is the molarity of 392 mL of solution that contains 0.47 mol NaCl?
jek_recluse [69]

Answer: 1.2 M

Explanation:

Given that:

volume of NaCl = 392 mL

Convert volume in milliliters to liters

(since 1000 mL = 1L

392 mL = 392/10000 = 0.392 L)

Concentration of NaCl = ?

Amount of moles of NaCl = 0.47 moles

Recall that the concentration of a solution depends on the amount of solute dissolved in a particular volume of solvent.

I.e Concentration in mol/L =

Amount in moles / Volume in liters

= 0.47 moles / 0.392 L

= 1.199 mol/L (Round up to the nearest tenth as 1.2 M)

Note that molarity is the same as concentration in moles per litres.

Thus, the molarity of 392 mL of solution that contains 0.47 mol NaCl is 1.2 M
