Softa [21]

The empirical rule states that, for data having a bell-shaped distribution, the portion of data values being within one standard deviation of the mean is approximately 95 percentage.

<h3>What is empirical rule?</h3>
  • The 68-95-99.7 rule, also known as the empirical rule.
  • It indicates where most of the values in a normal distribution are distributed.
  • The majority of values about 68% fall within the range of the mean.
  • The average value is within two standard deviations for about 95% of the data.
  • Almost all values, 99.7% of them, fall within a 3 standard deviation range.
  • According to the empirical rule, a statistical principle, practically all of the data for normally distributed samples will lie within three standard deviations of the mean.
  • Due to the fact that the empirical nature of the rule, it is occasionally referred to as the Empirical Rule.
  • Most data distributions fall under the Normal/Gaussian category.
  • The standard deviations of each measurement are calculated as departures from the mean and are presented.

9966 [12]
Presence of Oxygen in mitochondria is called Aerobic conditions and under this aerobic conditions Pyruvic acid is converted into Acetyl Co.A which enters Krebs' cycle
while in absence of oxygen which called Anaerobic conditions pyruvic acid is converted into Lactic acid to avoid accumulation of NADH⁺ which inhibit glycolysis and provide NAD⁺ required for glycolysis

What is the coefficient for O2 in the balanced version of the following chemical equation: C2H4+O2→CO2+H2O
andriy [413]

Answer:

3

Explanation:

Here's the balanced equation;

C2H4 + 3O2 → 2CO2 + 2H2O

C ⇒2                          C ⇒1 x 2 = 2

H ⇒4                          H ⇒2 x 2 = 4

O ⇒3 x 2 = 6             O ⇒ (2 x 2) + (2 x 1) = 6

Calculate the masses.
malfutka [58]

Answer:

a) Mass = 3.9 g

b) Mass = 0.395 g

Explanation:

Density is related to the mass and volume of a substance by the relation:

Density = \frac{Mass}{Volume}----(1)

a) Given:

Volume  = 4.00cm3

Density = 0.97 g/cm3

Based on equation (1)

Mass = density*volume = 0.97 g/cm3*4.00 cm3 =3.9 g

b) Given:

Volume  = 125 ml

Density = 3.16 g/L

1 ml = 0.001 L

Therefore, 125 ml = 0.125 L

Based on equation (1)

Mass = density*volume = 3.16 g/L*0.125L =0.395 g
