When a metal undergoes a reaction, especially with a nonmetal, you should look for the formation of salts or the formation of precipitates in the case the product is not soluble to water. Metals loses electrons to form positive ions which then reacts to nonmetals that are negatively charged ions.<span />
Answer:
= - 303.975 Joules
Explanation:
Given that:
The volume of the cylinder = 0.003 m^3
Now, to liters:
The volume = 0.003 *1000 L
= 3 L
For an open cylinder, we mean the atmospheric pressure is at standard condition.
Thus, the workdone = -PΔV
= - 1 atm (3 L)
= - 3 L atm
1 L atm to Joules
= 101.325 Joules
Therefore;
=- 3* 101.325 Joules
= - 303.975 Joules
Answer:
6 mols
Explanation:
Notice that on the left, there is one "O2" molecule, and one O2 results in two "H2O" molecules. So the ratio of O2 to H2O is 1 to 2
If we have 3 mols of oxygen, then per the ratio, we would have 6 mols of H2O, since 3*2=6
Answer:
Now this just because of decrease in acceleration while moving in upward direction. Just because she faced the upward hill and to accelerate at the same rate while moving upward always need some upward force but as janice was not applying any sort of large amount of force but however she was skating she faced faced the decrease in acceleration.
Explanation:
Due to decrease in acceleration she slowed downed while moving upward.
The graph attached can be well understood to analyze the scenario.
