1 mole of any gas under STP has volume 22.4 L
So 2.50 moles of any gas ( including oxygen)
2.50 mol *(22.4L/1 mol)=56.0 L
Answer:
B
Explanation:
by simlfying it you get HCO2
Solution :
Given :
Amount of anserine solution = 0.200 M
pH value is = 7.20
Preparation of 0.04 M solution of anserine from the 0.2 M solution.
0.2 M x
= 0.04 M x 1000 ml
= 200 ml
So the 200 ml of 0.2 M anserine solution is required to prepare0.04 M of anserine.
0.1 M x
= 0.04 x 1000 ml
= 400 ml
Therefore, 400 ml of HCl is needed.
The heavily crosslinked polyethylene that has a glass-transition temperature of 0°c to be an <u>thermoset (non-elastomer).</u>
A cross-linked kind of polyethylene has been known as cross-linked polyethylene, sometimes known by the acronyms PEX, XPE, or XLPE. It must be primarily utilized in residential water piping, high tension electrical cable insulation, hydronic radiant heating as well as cooling systems, construction management pipework systems, and infant play mats.
Tanks composed of linear polyethylene as well as XLPE are both constructed using heated resins to produce cured plastic. But because of the variations in how they are produced, the polyethylenes they produce have extremely varied structural strengths. Simply put, cross-linking is just the creation of links between polymer chains.
Therefore, the correct answer will be option (a).
