A researcher determines an organism to be eukaryotic, unicellular, and autotrophic. In which taxonomic group should this organis
IrinaVladis [17]

The taxonomic group that this organism should be classified in is: bacteria.

<h3>What is taxonomy?</h3>

Taxonomy can be defined as a scientific method that is typically used by researchers for the naming, classification and description of the various species of organisms such as animals, humans, and plants.

<h3>The taxonomic group for organisms.</h3>

In Science, there are various taxonomic group for organisms and these include:

  • Protista
  • Archaea
  • Animalia
  • Bacteria

Organisms classified as bacteria are eukaryotic, unicellular, and autotrophic. Thus, the taxonomic group that this organism should be classified in is bacteria.

When the 0.10 m solution of hclo2 is allowed to come to equilibrium, what percent of the acid molecules are ionized?
docker41 [41]

If 0.10 m solution of hclo2 is allowed to come to equilibrium, the percent of the acid molecules that is ionized is 29%

We have

HClO2 = 0.1 mole = 0.012

HClO + H2O ⇄ ClO₂⁻ + H₂O

Ka = 0.1α x 0.1α / 0.1(1-α)

= 0.1α²/1-α = 0.12

We have to form a quadratic equation from the above

0.1α² = 0.012 - 0.12α

We write the equation to be

0.1α² + 0.012 - 0.12α = 0

To solve the equation above, the quadratic formula calculator was used.

\frac{-b+-\sqrt{b^2-4ac} }{2}

alpha = 0.29

This is 29 percent. Therefore the percentage of ionization is 29%.

<h3>What is ionization?</h3>

This is the process through which neutral ions are chraged to become electrically charged.

A recent survey of cell phone users indicated that 56 percent of the respondents prefer to use cell phones for texting rather th
love history [14]

Assume all conditions for inference have been met, based on the confidence interval, the claim that is supported is that;

More than half of all people prefer texting.

<h3>Understanding Confidence Intervals</h3>

We are given;

Confidence Level; CL = 95%

Margin of error; MOE = 3%

Since 56 percent of the respondents prefer to use cell phones for texting rather than for making phone calls. It means that; x' = 56%

Thus;

CI = x' ± MOE

CI = 56% ± 3%

CI = 53% OR 59%

Thus, in conclusion we can say that more than half of the people prefer texting
