Answer:
Vsln=13.2mL
Explanation:
MwPb(NO3)2=331.2g/mol
⇒ Vsln = (1L Pb(NO3)2/0.200molPb(NO3)2) * (molPb(NO3)2/331.2gPb(NO3)2) * 0.875gPb(NO3)2
⇒ Vsln = 0.0132L (13.2mL)
<h3><u>Answer</u>;</h3>
D. All polysaccharides are made up of carbon, hydrogen, and oxygen.
<h3><u>Explanation</u>;</h3>
- A polysaccharide is a large molecule made of many monomers called monosaccharides such as glucose, galactose, fructose, etc.
- Polysaccharides can be homopolysaccharides, where all monosaccharides are the same or heteropolysaccharide in which the monosaccharides vary.
- They may be linear, where a molecule of polysaccharides has straight chain of monosaccharides, or branched polysaccharides in which a chain has arms.
- <em><u>All polysaccharides contain oxygen, hydrogen and carbon atoms like all the carbohydrates.</u></em>
Answer:
If a sample of 2 moles of nitric oxide gas was reacted with excess oxygen, 2 moles of nitrogen dioxide would be produced.
Explanation:
The balanced reaction is:
2 NO + O₂ → 2 NO₂
By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:
-
NO: 2 moles
- O₂: 1 mole
- NO₂: 2 moles
The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.
