Answer:
0.209 mol/L
Explanation:
Given data
- Mass of copper(lI) sulfate (solute): 11.7 g
- Volume of solution: 350 mL = 0.350 L
The molar mass of copper(Il) sulfate is 159.61 g/mol. The moles corresponding to 11.7 grams are:
11.7 g × (1 mol/159.61 g) = 0.0733 mol
The molarity of copper(Il) sulfate is:
M = moles of solute / liters of solution
M = 0.0733 mol / 0.350 L
M = 0.209 mol/L
Answer:
26 g
Explanation:
Write the balanced reaction first
CH4 + 2 O2 --> CO2 + 2 H2O
9.3g + 52.3g --> ? CO2
You must determine how much carbon dioxide can be made from each of the reactants. The maximum mass that can be made is the lower of the two.
From CH4:
9.3g CH4 (1molCH4/16.05gCH4) (1molCO2 / 1molCH4) (44.01g CH4 / 1molCO2) = 26 g
From O2:
52.3g O2 (1molO2/32gO2) (1molCO2/2molO2)(44.01g/1molCO2) = 36 g
Julian is correct because chlorophyll is neither used up nor formed in the chemical reaction of photosynthesis.
Explanation:
Julian is correct because chlorophyll is neither used up nor formed in the chemical reaction of photosynthesis. The reactants in photosynthesis are carbon dioxide and water.
- Photosynthesis is the process by which green plants manufacture their food in the presence of sunlight.
- In photosynthesis carbon dioxide combines with water to produce glucose and oxygen.
- Chlorophyll in plant is a green pigment that is used to trap sunlight during photosynthesis.

Answer:
A binary covalent compound is composed of two different elements (usually nonmetals). For example, a molecule of chlorine trifluoride, ClF3 contains 1 atom of chlorine and 3 atoms of fluorine.
Rule 1. The element with the lower group number is written first in the name; the element with the higher group number is written second in the name. Exception: when the compound contains oxygen and a halogen, the name of the halogen is the first word in the name.
Rule 2. If both elements are in the same group, the element with the higher period number is written first in the name.
Rule 3. The second element in the name is named as if it were an anion, i.e., by adding the suffix -ide to the root of the element name (e.g., fluorine = F, "fluoride" = F-; sulfur = S, "sulfide" = S2-).
Rule 4. Greek prefixes are used to indicate the number of atoms of each element in the chemical formula for the compound. Exception: if the compound contains one atom of the element that is written first in the name, the prefix "mono-" is not used.
