Answer:
Explanation:
Hello,
In this case, since the solution is formed by sodium chloride and water, we understand that for one mole of solution, we have 0.132 moles of sodium chloride and 0.868 moles of water, therefore, by using their molar masses we can compute their masses in the solution:
Thereby, we can compute the weight/weight percent as follows:
So we use the previously computed masses:
Best regards.
The answer is (3) An electron in the third shell has more energy than an electron in the second shell. The energy of electron will increase when number of shell increase.
Is there a specific topic you're talking about?
If this is about climate change:
Over the last century. the average surface temperature of the Earth has increased by 1.0°F. The eleven warmest years this century have occurred since 1980, with 1995 the warmest on record. The higher latitudes have warmed more than the equatorial regions.
I hope you found this helpful! :)
3050÷140
=21.79g
Therefore the was a mass of 21.79 grams in the sample
Answer: B
Kinetic Energy is the energy possessed by the body due to "motion".
