Answer:
The answer to your question is 35.4527 g
Explanation:
Data
Cl-35 abundance = 75.77 % mass Cl-35 = 34.9688
Cl-37 abundance = 24.23 % mass Cl-37 = 36.9659
Process
1.- Convert the percents to decimals
75.77% = 75.77/100 = 0.7577
24.23% = 24.23/100 = 0.2423
2.- Find the atomic weight
Average atomic weight = Abundance 1 x Mass Cl-35 +
Abundance 2 x Mass Cl-37
Substitution
Average atomic weight = (0.7577)(34.9688) + (0.2423 x 36.9659)
Simplification
Average atomic weight = 26.4959 + 8.9568
Result
Average atomic weight = 35.4527 g
Answer:
Black and Textured
Explanation:
Dark colors absorb more energy than light colors, and reflect less energy than light colors.
Rough surfaces absorb more energy than smooth surfaces, and reflect less energy than smooth surfaces.
Stirring affects how quickly a solute dissolves in a solvent, but has no effect on how much solute will dissolve. The amount of solute that will dissolve is affected by temperature - more will dissolve at higher temperatures. This is called the solubility of the solute
Answer:
88.1 moles of H₂
Explanation:
Let's make the reaction:
H₂(g) + CO₂(g) → H₂O(g) + CO(g)
Ratio is 1:1
Therefore, 1 mol of hydrogen reacts with 1 mol of carbon dioxide to produce 1 mol of water and 1 mol of carbon monoxide.
In conclusion, 88.1 moles of water must be produced by 88.1 moles of H₂
The reaction can also be written as an equilbrium
H₂(g) + CO₂(g) ⇄ H₂O(g) + CO(g) Kc
