Given the energy obtained by the human body from a candy bar = 915 kJ
Energy required to vaporize 1 g of water at it's boiling point is referred to as heat of vaporization of water.
The heat of vaporization of water = 2260 J/g
Mass of water that can be vaporized by 915 kJ of heat =
Density of water = 1 g/mL
Converting mass to volume in L of 405 g water:
Therefore, 0.405 L of water can be vaporized
Answer:- 10 L of ethane.
Solution:- The given balanced equation is:
From this equation, ethane and oxygen react in 2:7 mol ratio, the ratio of volumes would also be same if they are at same temperature and pressure.
Since 14 L of each gas are taken, the oxygen will be the limiting reactant and ethane will be the excess reactant. Let's calculate the volume of ethane used:
=
From above calculations, 4 L of ethane are used. So, excess volume of ethane left after the completion of reaction = 14 L - 4 L = 10 L
Hence, 10 L of ethane will be remaining.
Answer:
18 km
Explanation:
To know the distance, you need to be clear in the concept of distance.
According to the physics, the distance is a measurement that refers to the fact of how much an object has move from one point to another.
In this case, we have a person named Steve and he's walking through several points.
To calculate the distance that he moved, you just need to sum all the values of distance. In this case, it's not neccesary to do calculations regarding the components of the x or y axis, because we are not talking about displacement, where it actually counts. But in this case, we just need all the covered distance that Steven walked since the beggining.
So, no more talk, let's do calculations:
D = 5 + 2 + 9 + 2 = 18 km
So the final answer would be:
<h2>
Distance = 18 km</h2>
Hope this helps
I mean you could put something about how we are comsumers. We consume and them spread waste that comes from us that could help plants grow ( as a fertilizer)
Let me know if it helped.
