Answer:
Balance chemical equation is
O2(g) + 2H2(g) --> 2H20(g)
a. 0.20 mol 02 --> 0.225mol H20
b. 0.30 mol H2 --> 2.7mol H20
Answer: Andre. If it is used as an antifreeze, one would infer that it's freezing point is less than water.
Explanation:
The freezing point of ethylene glycol alone (100%) is -12.9oC. That is somewhat less than the freezing point of water but nowhere near the freezing point of water containing 70% ethylene glycol.
Answer:
Demonstrate familiarity with the pH scale ... body (excluding things like stomach acid) measure around 7.2 and 7.6 on the pH scale (a 7 is neutral on the scale). ... The pH of a solution is a measure of its acidity or alkalinity (base). ... Using a pH meter, you find the pH of an unknown solution to be 8.0.
Explanation:
Answer:
Cellular respiration
Explanation:
Oxygen is required by the cell in the Krebs cycle as the ultimate proton acceptor (creating water an end product during making out ATPs). During the conversion of pyruvate from glycolysis to Acetyl-CoA that enters the Krebs cycle, the pyruvate is decarboxylated (or oxidized) hence creating carbon IV oxide as a byproduct.
As given that some volume of water has been dispensed say "x mL"
The initial weight of bottle =8.4376 g
The final weight of bottle + water =28.5845 g
So weight of water transferred = 28.5845 g - 8.4376 g = 20.1469 g
Now there is a relation between density, mass and volume
density = mass / volume
Therefore
Volume = mass / density
So volume of water dispensed = mass dispensed / density =20.1469 g / 0.9967867 g/ml.
Volume of water = 20.2118467 mL
