Properties like atomic number, valency etc...
We have two unknowns for this problem. These are the amount of Ch4 and the amount of C2H6. We let these as x and y respectively. It should be that we generate two equation in order to solve this problem. We do as follows:
Equation 1:
x + y = 5
Equation 2
CO2 produced from CH4 + CO2 produced from C2H6 = 14.09
<span>x(44.01/16.05) + y(4)(44.01)/(2)(30.08) = 14.09
</span>2.74x +2.93y = 14.09
Solving simultaneously,
x = 2.95 g CH4
y= 2.05 g C2H6
Given the number of Mg atoms is
We know that 1 mol of any substance has Avogadro number of formula units.
Converting number of atoms to mol:
Converting mol to mass of Mg:
Therefore mass of Mg is <u>2.99 g</u>

<h3>What is heme?</h3>
The protein haemoglobin, which is required to bind oxygen in the bloodstream, is a precursor to heme. Both the liver and bone marrow can biosynthesize heme.
Heme is a coordination complex that "consists of an iron ion coupled to porphyrin serving as a tetradentate ligand, and to one or two axial ligands," according to biological terminology. The term is ill-defined, and many illustrations leave out the axial ligands.
Heme is one of the most often utilised metalloporphyrins employed by metalloproteins as prosthetic groups, and it defines the family of proteins known as hemoproteins.
The biologically significant hemoproteins heme peroxidase, myoglobin, cytochromes, catalases, and endothelial nitric oxide synthase all contain heme, which is most generally known as a component of haemoglobin, the red colour in blood.

Answer:
If your lab has litmus paper, you can use it to determine your solution's pH. When you place a drop of a solution on the litmus paper, the paper changes color based on the pH of the solution. Once the color changes, you can compare it to the color chart on the paper's package to find the pH.
Explanation:
A solution's pH will be a number between 0 and 14. A solution with a pH of 7 is classified as neutral. If the pH is lower than 7, the solution is acidic. When pH is higher than 7, the solution is basic. These numbers describe the concentration of hydrogen ions in the solution and increase on a negative logarithmic scale.
For example, If Solution A has a pH of 3 and Solution B has a pH of 1, then Solution B has 100 times as many hydrogen ions than A and is therefore 100 times more acidic.
