Answer:
Darker colored items absorb more of the sunlight.
Explanation:
Lighter colored item tend to reflect more of the sunlight
Answer is: true.
Demand decreases and competition increases decrease the quantity supplied.
Quantity supplied is the quantity of a commodity that producers are willing to sell at a particular price at a particular point of time.
Quantity demanded is the quantity of a commodity that people are willing to buy at a particular price at a particular point of time.
Quantity demanded can change at the same price depending upon factors like recession, changes in the taste of the consumer.
Competition is rivalry between two or more economic groups.
The question is asking to state the conclusion that can be formulated, base on the problem or the given analysis of the data, about the accuracy and precision and base on my research, i would say that the Accuracy is Poor but the Precision is Good. I hope this would help you
1.1 moles of C10H8 is the limiting reagent in the reaction between reaction C10H8 and O2
.
C10H8 + 12O2 ----> 10CO2 + 4H2O
C10H8 is the limiting reagent since 1.1 moles of C10H8 is totally consumed during the reaction
Answer:
58.44 g of NaCl are needed.
Explanation:
Given data:
Mass of NaCl needed = ?
Volume of solution = 200 mL (200/1000 =0.2 L)
Molarity of solution = 5 M
Solution:
We will solve this problem through molarity formula.
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
Now we will put the values.
5 M = moles of solute / 0.2 L
Moles of solute = 5 mol/L × 0.2 L
Moles of solute = 1 mol
Mass of sodium chloride:
Mass = number of moles × molar mass
Mass = 1 mol × 58.44 g/mol
Mass = 58.44 g
Thus, 58.44 g of NaCl needed.
