Phosphorus is usually a limiting factor or element.

<h3>Is phosphorus a limiting element or factor?</h3>

Phosphorus is usually considered a limiting factor or nutrient in aquatic ecosystems, meaning that the available quantity of this nutrient controls the pace at which algae and aquatic plants are produced.

In other words, phosphorus is a limiting nutrient for aquatic organisms. Its supply is usually small compared to available aquatic organisms.

Thus, Phosphorus is usually a limiting factor or element.

What is the volume of 0.25 mol of ammonia gas at 1.00 atm and 273 K? (R= 0.0821 Latm/molK)What is the volume of 0.25 mol of ammo

ICE Princess25 [194]

Answer:

5.6L

Explanation:

Given parameters:

number of moles = 0.25mol

pressure on gas = 1atm

temperature = 273K

Gas constant R = 0.0821Latm/molK

Unknown:

Volume of gas = ?

Solution:

Using the ideal gas equation, we can solve this problem. The equation is a combination of the three gas laws: Boyle's law, Charles's law and Avogadro's law.

It is mathematically expressed as;

PV = nRT

where P is the pressure

V is the volume

R is the gas constant

T is the temperature

n is the number of moles

All the parameters are in the appropriate units and we simply solve for the volume of the gas;

1 x V = 0.25 x 0.0821 x 273

V = 5.6L

Drag the tiles to the correct boxes to complete the pairs.

Darina [25.2K]

After matching each set of values of a function to the pair of points that satisfy the function, we get

1-4

2-2

3-1

4-3

(4,3) and (6.7) rate of change = 2, and initial value = -5

k= 7-3/6-4 = 2, y=2x-5

(2,10) and (5, 19) rate of change=3, and initial value = 4

k= 19-10/5-2 = 9/3 = 3, y=3x+4

(2,5) and (5.2)→ rate of change = -1, and initial value = 7.

k= 2-5/5-2 = -3/3 = -1, y= -x+7

(2.4) and (4,3) →→ rate of change = -0.5, and initial value =5

k= 3-4/4-2 = -1/2 =-0.5, y=-0.5x+5

The set of input values and the set of output values for a function each have their own names. The domain of the function is the collection of input values. The range of the function is the collection of output values.

Correct question: Drag the tiles to the correct boxes to complete the pairs. Match each set of values of a function to the pair of points that satisfy the function. rate of change = -1, and initial value = 7 rate of change = 2, and initial value = -5 rate of change = -0.5, and initial value = 5 rate of change = 3, and initial value = 4 (4, 3) and (6, 7) arrowRight (2, 10) and (5, 19) arrowRight (2, 5) and (5, 2) arrowRight (2, 4) and (4, 3) arrowRight

Norman Triplett observed that adolescents wound a fishing reel faster in the presence of someone working simultaneously on the s

slavikrds [6]

Answer:

social facilitation

Explanation:

The concept of social facilitation was first proposed by Norman Triplett. After observing a cycling event, in which he noticed that cyclist performed better when they have others around competing with them, rather than cycling alone just against time. This led him to duct an experiment where he gave some children strings to wound fishing reel. He observed that, children wound the fishing reel faster in the presence of other children performing similar task, when compared to when perform such task alone.

This concept discovered by Norman Triplett, best illustrates the concept of social facilitation, which posits that, individuals tend to perform better in the mere presence of others or when they perform a task with others, than when performing the task alone.
