Answer:

$\boxed {\boxed {\sf A. \ 19,320 \ kg/m^3}}$

Explanation:

We want to find the density. The formula is mass over volume.

$\rho = \frac{m}{v}$

The mass is 500 kilograms. The volume is 0.026 cubic meters.

$m= 500 \ kg \\v=0.026 \ m^3$

Substitute the values into the formula.

$\rho= \frac{ 500 \ kg}{ 0.026 \ m^3}$

Divide.

$\rho = 19230.7692 \ kg/m^3$

This is just about equal to 19,320 kg/m³, so choice A is correct.

How is the formation of covalent bonds similar to kids sharing markers? how is it different? if possible, discuss your answer wi

vagabundo [1.1K]

A covalent bond means shared electrons between atoms. This is similar to kids sharing markers because the markers (electrons) are being shared between the kids (atoms). Covalent bonds are different than this metaphor because 1) the electrons are constantly moving about while the kids can steal and keep the markers and 2) the electrons and atoms are physically smaller

Data has been collected to show that at a given wavelength in a 1 cm pathlength cell, Beer's Law for the absorbance of Co2 is li

White raven [17]

Answer : The concentration of a solution with an absorbance of 0.420 is, 0.162 M

Explanation :

Using Beer-Lambert's law :

$A=\epsilon \times C\times l$

As per question, at constant path-length there is a direct relation between absorbance and concentration.

$\frac{A_1}{A_2}=\frac{C_1}{C_2}$

where,

A = absorbance of solution

C = concentration of solution

l = path length

$A_1$ = initial absorbance = 0.350

$A_2$ = final absorbance = 0.420

$C_1$ = initial concentration = 0.135 M

$C_2$ = final concentration = ?

Now put all the given value in the above relation, we get:

$\frac{0.350}{0.420}=\frac{0.135}{C_2}$

$C_2=0.162M$

Thus, the concentration of a solution with an absorbance of 0.420 is, 0.162 M

On which part of the carbon cycle have humans had the greatest impact? storage of co2 in the oceans all of the answer options ha

yarga [219]

Hello!

The part of the carbon cycle where humans had the greatest impact is the return of CO₂ to the atmosphere by burning of ancient organic matter.

The ancient organic matter is also called Fossil Fuels. Some Fossil Fuels are Petroleum and Coal. Fossil Fuels are used to power our society and are burned to provide energy for power plants and vehicles, and by burning them, Carbon Dioxide (CO₂) is produced, increasing the natural concentration of this compound in the atmosphere.

Have a nice day!
