The burning of methane gas, given below, is a redox reaction. which part of the reaction illustrates oxidation, Ch4+O2---CO2+H2O<span>CH4---CO2</span>
Your answer is B and the element is Carbon
So what your looking for is matching isotopes. Isotopes are elements that are the same in amount of protons but different in mass meaning different number in neutrons. Because when you add the total protons and neutrons together you get your atomic mass. So this can be written as X=said element, top number above=different atomic mass, bottom number below=atomic number. Hope this help!!
Be careful because answer A has same masses but different atomic numbers so different atoms(elements)!!!
Well when the sun makes water dissaper thats usually evaporation.
The chemical changes is when the plants absorb the energy from the sunlight and convert water and carbon dioxide into sugar and oxygen gas. Physically nothing has changed. The plant still looks the sam changes occur internally these internal changes are chemical in nature.
Answer:
Check explanation section.
Explanation:
Isotopes are chemical species of the same elements with different number of neutrons but the same protons.
Both Chlorine-35 and Chlorine-36 are the same because they are both isotopes of the same elements that is Chlorine. Also, both Chlorine-35 and Chlorine-36 have the same number of protons which has the value equal to 17.
The difference between Chlorine-35 and Chlorine-36 is that Chlorine-35 is stable and has the abundance of 75.77% whole Chlorine-36 is found in trace.
Also Chlorine-35 has a neutrons value of 18 while that of Chlorine-36 is 19.

Answer:</h3>
43.5 mL
<h3>
Explanation:</h3>
We are given;
- Molarity of dilute acetic acid is 1.74 M
- Volume of the solution that needs to be prepared is 200 mL
- Molarity of the stock solution 8 M
We are required to determine the volume of acid that must be used.
- We need to know the dilution formula;
- According to the dilution equation;
M1V1 = M2V2
Rearranging the formula;
V1 = M2V2 ÷ M1
= (1.74 M × 200 mL) ÷ 8 M
= 43.5 mL
Therefore, the volume of the concentrated acid that must be added is 43.5 mL
