Answer: the longitude line rotates with Earth, 360 degrees in 24 hours.
Explanation: In the old days, the position of the sun was used to tell which time of the day it is. But more modern findings, has shown that the longitude line matters too.
Answer:
2.5
Explanation:
From the question given above, the following data were obtained:
Molarity of NaOH = 3.0x10¯³ M
pOH =?
Next, we shall determine the concentration of the hydroxide ion in the solution. This can be obtained as follow:
NaOH (aq) —> Na⁺ (aq) + OH¯ (aq)
From the balanced equation above,
1 mole of NaOH produced 1 mole of OH¯.
Therefore, 3.0x10¯³ M NaOH will also produce 3.0x10¯³ M OH¯.
Finally, we shall determine the pOH of the solution. This can be obtained as illustrated below:
Concentration of hydroxide ion [OH¯] = 3.0x10¯³ M
pOH =?
pOH = – Log [OH¯]
pOH = – Log 3.0x10¯³
pOH = 2.5
Thus, the pOH of the solution is 2.5
However, antibiotics can also have harmful side effects, increase bacterial resistance, and sometimes even work against your immune system. Antibiotics are not effective against viruses,
Hence the answer is C
The potential energy diagram is a common way of depicting the reaction profile. The following are true about the diagram;
- The activation energy of the reaction is 35kJ.
- The enthalpy change of this reaction is 25kJ.
- The slope of the diagram is positive.
- The reaction is endothermic.
<h3>What is a potential energy diagram?</h3>
A potential energy diagram is a diagram that shows the conversion of reactants to products. It can tell us whether the reaction is endothermic or exothermic.
1) From the diagram, the activation energy of the reaction = 65 kJ - 30 kJ = 35 kJ
2) The enthalpy change of this reaction = 55kJ - 30 kJ = 25kJ.
3) The slope of the diagram is positive.
4) The reaction is endothermic.
