Answer:

M_{acid}=26.804g/mol

Explanation:

Hello,

In this case, by knowing that the used NaOH equals in moles the acid (monoprotic) as shown below, during the titration:

n_{acid}=n_{NaOH}

By knowing the volume and the concentration of the NaOH, one obtains:

n_{acid}=0.05238L*0.396\frac{mol}{L}=0.0207mol

Thus, the molar mass of the acid is computed based on the previously computed moles and the given mass as follows:

M_{acid}=\frac{m_{acid}}{n_{acid}}=\frac{0.556g}{0.0207mol}=26.804g/mol

Best regards.

Answer:

Option 3 is correct.

The atomic nucleus of each element has a unique number of protons. Therefore, the energy of the electron layers of the atoms of each element is unique.

If we have the energy released from each electron transfer between the layers of the atom, we can identify the element.

What are some positive applications for allelotoxin?
pogonyaev

Positive applications for allelotoxin is that it prevents plants from enduring any type of competition with other species.

<h3>What is Allelopathy?</h3>

This is the process in which a plant inhibits the growth of another through a secretion of a chemical which is referred to as allelotoxin.

This technique however reduces biodiversity which isn't ideal so as to prevent organisms from going extinct and also reduces adaptation or evolution due to the reduced or non growth of the plant species which are affected.

A common example is  the sorghum plant preventing of the growth of weeds thereby resulting in the most appropriate choices for the positive applications of allelotoxin.

inna [77]

Answer:

The volume of the gasoline in the tank is 18.85 cubic feet

Explanation:

The tank is a cylinder. The equation for calculating the cylinder volumen is πr²*h, r is radius and h is height. π is approximately 3.1416. So,  The tank is  resting horizontally on its side, its radius is 2 feet/2= 1 feet. h=a tank long= 6 feet.

With equation:

Vol gasoline=3.1416*1²*6=18.85 feet ³
