Which statement describes the reaction involved in cellular respiration?
Masteriza [31]

Answer:

i think its b

Explanation:

if you removed the C02 from the atmosphere that

willl make the 02 and it will

released for the atmosphere

which means, Photosynthesis removes CO2 from the atmosphere and replaces it with O2. Respiration takes O2 from the atmosphere and replaces it with CO2. However, these processes are not in balance. Not all organic matter is oxidized.   photosynthesis mean if you dont know: Photosynthesis – plants produce their own food in the form of glucose using the process of photosynthesis. This process uses sunlight (and so only occurs during the day) to remove carbon dioxide from the atmosphere and release oxygen.

this is why the CO2 is removed and the 02 is released into the atmosphere,   Consumers such as animals, fungi, and bacteria get their energy from this excess biomass either while living or dead and decaying. Oxygen from the atmosphere is combined with carbohydrates to liberate the stored energy. ... Photosynthesis removes CO2 from the atmosphere and replaces it with O2.

and if the CO2 is release from the atmosphere this will happen --> Carbon dioxide causes about 20 percent of Earth's greenhouse effect; water vapor accounts for about 50 percent; and clouds account for 25 percent. ... Likewise, when carbon dioxide concentrations rise, air temperatures go up, and more water vapor evaporates into the atmosphere—which then amplifies greenhouse heating CO2 effects the wither,   Scientists say that if CO2 doubles, it could raise the average global temperature of the Earth between two and five degrees Celsius. We are already increasing the amount of energy that bounces back to the Earth. Because of the greenhouse effect, this is causing global warming with its many destructive impacts.     im sorry that i gave alot of facts my teacher said its good to add alot of facts some of my thoughts thank you i hope you get this right :)

A student pipets 10 ml of a 0.0693 m solution of kbr into a 500 ml volumetric flask and dilutes to the mark. what is the concent
Sonja [21]

The initial concentration of solution is 0.0693 M. The volume of solution taken is 10 mL and it is diluted to a final volume of 500 mL.

According to dilution law, the product of initial concentration and volume is equal to the product of final concentration and volume as follows:

C_{1}V_{1}=C_{2}V_{2}

Here, C_{1} is initial concentration, C_{2} is final concentration, V_{1} is initial volume and V_{2} is final volume.

Rearranging to calculate final concentration,

C_{2}=\frac{C_{1}\times V_{1}}{V_{2}}

Putting the values,

C_{2}=\frac{0.0693 M\times 10 mL}{500 mL}=0.001386 M

Therefore, concentration of the resulting solution is 0.001386 M.

Which is a disadvantage of using chemical indicators? they are expensive to use. they measure ph directly. they must be selected
dexar [7]

Chemical indicators are the chemical reagents that show the change in reaction by changing color. Chemical indicators must be chosen with a narrow pH range.

<h3>What are indicators?</h3>

Indicators are the solutions or the substances used for the qualitative and the quantitative measurement by a change in color because of the absence or the presence of the sample concentration.

The chemical indicators cannot detect the exact pH and should be used with a narrow range of pH.

Therefore, option C. the narrow range of pH is the disadvantage of chemical indicators.

List the number of protons neutrons and electrons in 13/6 C
Charra [1.4K]
<h3>Answer:</h3>

             Number of Protons =  6

             Number of Electrons  =  6

             Number of Neutrons  =  7

<h3>Explanation:</h3>

Number of Protons:

                               As the number of protons present in the nucleus are equal to the atomic number therefore, using periodic table one can easily find out the atomic number of C atom. Hence, C is present in group 14 and period 2 and having an atomic number of 6. Therefore, number of protons in C atom are 6.

Number of Electrons:

                                 As shown in statement, C is not carrying any type of charge. It means this atom is neutral in nature. Which means, it is carrying the same number of electrons as the number of protons in order to give a neutral atom. Therefore, it contains 6 electrons.

Number of Neutrons:

                                  Number of neutrons can be calculated using following formula,

                  No. of Neutrons  =  Atomic Mass - Number of Protons

As,

                                    Atomic Mass  =  13

So,

                                    No. of Neutrons  =  13 - 6

                                    No. of Neutrons  =  7
