Answer: 0.00867 moldm-3
Explanation:
Since the reaction is 1st order,
Rate of reaction=∆[A]÷t
0.646-0.0146/72.8= 0.00867
Remember that in a first order reaction, the rate of reaction depends on change in the concentration of only one of the reaction species, A in the problem above.
A division or split
in biology a cell division
Answer:
The volume of CO2 produced is 6.0 L (option D)
Explanation:
Step 1: Data given
Volume of oxygen = 3.0 L
Carbon monoxide = CO = in excess
Step 2: The balanced equation
2 CO (g) + O2 (g) → 2 CO2 (g)
Step 3: Calculate moles of O2
1 mol of gas at STP = 22.4 L
3.0 L = 0.134 moles
Step 3: Calculate moles of CO2
For 2 moles CO we need 1 mol of O2 to produce 2 moles of CO2
For 0.134 moles O2 we'll have 2*0.134 = 0.268 moles CO2
Step 4: Calculate volume of CO2
1 mol = 22.4 L
0.268 mol = 22.4 * 0.268 = 6.0 L
The volume of CO2 produced is 6.0 L
The first one is unbalanced, the photo below is proof.
Explanation:
There are so many reasons why natural resources are unevenly distributed in nature.
The major control on distribution of resource is basically the geologic setting of place.
Here are some of reasons:
- Geological setting of place: most natural mineral resources are formed in areas where the best interaction between the ore forming processes and the environment occurs. No one can determine or control that.
- Climate: the climate is the average weather condition of a place over an extended period of time. Different natural resources can be allocated to a place based on the dominant climatic condition in that place.
