Answer:
A bottle that contains 0.95 moles of hydrogen peroxide per liter of solution contains 32.31 g of hydrogen peroxide per liter of the solution.
Explanation:
First, recall that:
<em>Molarity of a substance = no of moles of the substance/volume of the solution in liters.</em>
In this case, the number of moles of hydrogen peroxide is 0.95 mole while the volume of the solution is one liter. Thus;
Molarity of hydrogen peroxide = 0.95/1 = 0.95 M.
Also recall that:
<em>no of moles of a substance = mass of the substance/molar mass of the substance.</em>
Thus;
mass of substance = no of moles x molar mass.
In this case, the no of moles of hydrogen peroxide is 0.95 while the molar mass is 34.01 g/mol. Hence;
mass of hydrogen peroxide = 0.95 x 34.01 = 32.31 g
<em>Hence, a bottle that contains 0.95 moles of hydrogen peroxide per liter of solution contains 32.31 g of hydrogen peroxide per liter of the solution. The solution also has a hydrogen peroxide molarity of 0.95 M. </em>
Answer:
The correct answer is cellular respiration is a single chemical reaction with just one step.
Explanation:
Cellular respiration is a process which includes 3 principle metabolic pathways 1 glycolysis 2 TCA cycle 3 oxidative phosphorylation.
Glycolysis is a 10 steps enzyme catalyzed reaction during which glucose is converted to pyruvate.Glycolysis occur within cytosol of a cell.
The next two pathways TCA cycle and oxidative phosphorylation are multi step process in which the pyruvate undergo various enzyme catalyzed biochemical reaction to produce CO2,H2O and ATP in form of energy.
From this point of view it can be stated that cellular respiration is not a single step reaction.
P goes with true breeding parents. The other two descriptions aren't quite right. F1 refers to the offspring of P. F2 refers to the offspring of F1. The descriptions are already in the correct order.

A black body is a material that takes in a wave when the wave hits it. It <span>refers to an opaque object that emits thermal radiation. A perfect </span>blackbody<span> is one that absorbs all incoming light and does not reflect any. Hope this answers the question. Have a nice day.</span>
