Convert 2.41 x 10^2 m to cm

Chemistry
1 answer:
JulijaS [17]3 years ago
4 0

Answer:

2.41*10² m equals 2.41*10⁴ cm

Explanation:

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them. That is, what is intended with it is to find the fourth term of a proportion knowing the other three. Remember that proportionality is a constant relationship or ratio between different magnitudes.

If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other) , the direct rule of three must be applied. To solve a direct rule of three, the following formula must be followed:

a ⇒ b

c ⇒ x

So: x=\frac{c*b}{a}

In this case the rule of three can be applied as follows: if 1 m equals 100 cm, 2.41*10² m equals how many cm?

cm=\frac{2.41*10^{2} m*100 cm}{1 m}

cm= 24100 = 2.41*10⁴

<u><em>2.41*10² m equals 2.41*10⁴ cm</em></u>

Calculate the lattice energy for NaF (s) given the following
san4es73 [151]

Answer: E

Explanation:

The lattice energy is the energy change when one mole of a crystal is formed from its components ions in its gaseous sate

Therefore lattice energy = heat of Sublimation+ ionization energy +electron affinity-(heat of formation)

Therefore lattice Energy =     109 +495 -328 +570.

Lattice energy = --923kjmol-1

A scientist could use DNA as a molecular clock to do which of the following? (2 points)
ad-work [718]

Explanation:

<u></u>

<u>-to determine how long ago two species of animals shared an ancestor</u>

<u></u>

The molecular lock describes a method which utilizes mutation rates for DNA over time, to determine the divergence of two species sharing common ancestry,due to evolution. Along with  genetic drift, selective mating and natural selection, evolution may occur within populations due to spontaneous heritable changes to DNA, called mutations, over time.

Further Explanation:

During reproduction, other events, such as crossing over during mitosis and meiosis, mutations lead to increases in genetic variation. This variation refers to the genetic characteristics present within a species. Mutations may be either beneficial or deleterious; they are maintained within cells, as they form new traits called alleles. Beneficial mutations may confer traits that increase the fitness of a species, along with ensuring survival by conferring a protective advantage- these phenotypic differences between organisms are called adaptations.

Sequences of DNA make up genes which can have different forms called alleles. DNA, which makes up the genotype, is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins which make up the phenotype of an organism. Mutations in DNA sequences affect the corresponding mRNA and thus the protein encoded.

In 1928, 47.5 g of a new element was isolated from 660 kg of the ore molybdenite. the percent by mass of this element in the ore
vitfil [10]

To take the percent by mass of this element, we use the formula:

% mass = (mass of element / mass of ore) * 100%

% mass = (47.5 g / (660 kg * 1000 g / kg)) * 100*

<span>% mass = 7.20 x 10^-3 %</span>

A student determines that she used 0.0665 mol of sodium hydroxide (NaOH) to completely titrate 25.00 mL of sulfuric acid solutio
AysviL [449]

To determine the concentration of one solution which is specifically basic or acidic solution through taking advantage on its points of equivalence, titration analysis is done.

Let us determine the reaction for the titration below:

2NaOH +2H2SO4 = Na2SO4 +2H2O

 

So,

0.0665 mol NaOH (2 mol H2SO4/ 2mol NaOH) / .025 L solution 

= 2.62 M H2SO4


The answer is the fourth option: 

<span>2.62 M</span>
