The following flow diagram shows the various steps of elimination of waste through urine. There is an error in one of the steps. (5 points)



What is the error in the diagram?
Step 2 should be the ureters carry urine to the urethra.
Step 2 should be the kidneys carry urine to the bladder.
Step 3 should be urine leaves the body through kidneys.
Step 1 should be urine flows from the kidneys to the ureters.

Answer:

The specific heat of the substance is 1.21 [tex]\frac{J}{g*C}[/tex]

Explanation:

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

There is a direct proportional relationship between heat and temperature. The constant of proportionality depends on the substance that constitutes the body as on its mass, and is the product of the specific heat by the mass of the body. So, the equation that allows calculating heat exchanges is:

Q = c*m*ΔT

where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.

In this case:

Replacing:

1108 J= c*83 g* 11 C

Solving:

[tex]c=\frac{1108 J}{83 g* 11 C}[/tex]

c= 1.21 [tex]\frac{J}{g*C}[/tex]

The specific heat of the substance is 1.21 [tex]\frac{J}{g*C}[/tex]

Answer:

The application of reflection in the use of the microscopes.

Explanation:

Reflection is one of the properties of light. Reflection is a phenomenon whereby light waves hitting a surface is bounced off. Reflection helps us to see light and colors. This behavior of light is harnessed in the design of the microscope.

The light reflected by the microscope helps the researcher to view the specimen in his slide. Also, the mirrors placed in measuring devices reflects light that helps an observer to take an accurate reading.

im sorry i dont know this i really need points for my maths test

Answer:

It depends on the situation. Most things are better learning from others because others can see what you cant. On the other hand there are some situations were only you can learn from. Take pain as an example. Others can talk about pain as much as they would like but your body dosent know what that feels like unless it feels it on its own and learns from it. An example of learning from others would be smarts such as math, science, history and so forth.

Explanation:

Answer:

An exothermic process releases heat, causing the temperature of the immediate surroundings to rise. An ethothermic process absorbs heat and cools the surroundings. Hope this helped.

The easiest way to explain endo and exothermic reactions are that endothermic reactions absorb energy and exothermic reactions release energy.

The way I remember this is that with exothermic reactions, the heat exits. Endothermic is just the opposite.

Hope this helps :)

This problem is providing the mass of salt, 15 g, that is dissolved in 100 mL of water, so its concentration is required and found to be 15 % according to the following calculations:

In chemistry, units of concentration in solutions are used to represent the relative amount of a solute that is dissolved in a solvent. Thus, in this case, we refer to a salt-water solution, whose concentration is calculated via:

[tex]\% m=\frac{m_{salt}}{m_{water}}*100\%[/tex]

In such a way, given the mass of salt, 15 g and volume of water, or solution, 100 mL, one obtains the following:

[tex]\% m=\frac{15g}{100g}*100\% \\\\\% m=15\%[/tex]

Answer:

78.04g of 0.448 moles must be added

Explanation:

Using H-H equation we can find the pH of the buffer:

pH = pKa + log [A⁻] / [HA]

Where pH is the pH of the buffer = 7.2

pKa = 7.1

[A⁻] = [K₂HPO₄]

[HA] = [KH₂PO₄]

Replacing:

7.2 = 7.1 + log [K₂HPO₄] / [KH₂PO₄]

0.1 = log [K₂HPO₄] / [KH₂PO₄]

1.2589 = [K₂HPO₄] / [KH₂PO₄] (1)

And as the  concentration of the buffer is:

1M = [K₂HPO₄] + [KH₂PO₄] (2)

Replacing (2) in (1):

1.2589 = 1M - [KH₂PO₄] / [KH₂PO₄]

1.2589 [KH₂PO₄] = 1M - [KH₂PO₄]

2.2589 [KH₂PO₄] = 1M

[KH₂PO₄] = 0.44M

And [K₂HPO₄] = 0.56M

In 800mL = 0.8L:

0.8L * (0.56mol / L) = 0.448 moles K₂HPO₄. The mass is -Molar mass K₂HPO₄: 174.2g/mol-:

0.448 moles * (174.2g / mol) =
