A typical carbon atom has six protons, six neutrons, and six electrons. Which of these has the least amount of mass?A) one Proton
B) one Neutron
C) six Electrons
D) These masses are too tiny to measure

Biotic components are the living components of an ecosystem. The biotic factor that limits the carrying capacity of any habitat is activity of decomposers, i.e., option B.

What are decomposers?

The organisms that usually feed on dead and decaying organisms and whose digestion is external one are called as decomposers.

The bioticfactor that limits the carryingcapacity of any habitat is activity of decomposers.

Thus, the correct option is B.

Answer:

Mass is how much matter an object has. Weight is how much gravity an object is being acted upon.

Explanation:

The mass of an object will stay the same no matter where you place it. But if you were to place the object, in the moon for example, then the weight of the object would be less since there is less gravity on the moon.

Answer:

B.) Possibly making an infrence.

Explanation:

Judging on what sshe saw, she can try to infer or come up with an answer. [based on what she observed.]

Answer:

The heat of reaction when hydrogen and oxygen combine to form water is :

C. 571.6 kJ

Explanation:

Enthalpy Change = The enthalpy change for the formation of 1 mole of the substance from their standard state is called the enthalpy of formation.

This is intensive quantity as it is fixed for 1 mole .

Intensive properties = Those properties which are independent on the amount of the substance are intensive properties.

The value of these quantities does not get halve if you divide the substance into two equal parts. example , density, refractive index.

However , the enthalpy of reaction is extensive. Because on increasing the amount the value of the enthalpy also get doubles

Hence for this reaction :

Its value is -285.8 kJ for 1 mole

And here two moles are present . so the value of molar enthalpy is:

-285.8 x 2 = -571.6 kJ

Answer:

                     69.036 g of Compound is required to obtain 48.45 g of Oxygen.

Explanation:

                    Let us assume that the total mass of the compound is 100 g. So it means that this compound weighing 100 is composed 70.18 % of Oxygen or among 100 g of this compound 70.18 g is constituted by oxygen only. Hence, we can make a relation as that,

                      70.18 g O is present in  =  100 g of a Compound

So,

         48.45 g of O will be present in  =  X g of a Compound

Solving for X,

                        X  =  100 g × 48.45 g ÷ 70.18 g

                        X  =  69.036 g of Compound

When the frequency of the waves increases, its energy increases, while the wavelength decreases.  

• A travelling disturbance, which mediates energy from one place to another is known as a wave.  

• The tendency to do work or cause a change is known as the energy.  

• Waves can be determined with the help of frequency and wavelength.  

• In a given unit of time, the number of complete wavelengths is known as frequency.  

• With the increase of the size of wavelengths, its energy and frequencydecreases.  

• There are two basic kind of waves, that is, electromagnetic and mechanical waves.  

• The waves, which can travel through a medium or a vacuum is known as the electromagnetic waves.  

• The waves with long wavelengths comprise less energy than waves with short wavelengths.  

Thus, correct answer is option d, that is, energy increases, wavelength decreases.

As the frequency is how many waves pass a fixed point in certain amount of times. This means that the waves get closer together and, therefore, the wavelength decreases. It also means that the wave has more energy.

Answer: D) Energy increases, wavelength decreases
