To get the concentration of the second solution let us use the following formulae
C1V1=C2V2 where C1 is concentration of first solution and V1 is the volume of solution first solution. on the other hand C2 is the concentration of second solution and V2 is the volume of second solution.
therefore
0.8×2=(2+10)×C2
1.6 =12×C2
1.6/12=C2
C2 = 0.1333mg/mL
Answer:
Heat
Explanation:
Friction can help convert heat into kinetic energy and kinetic energy into heat. Friction can be thought of as particles from different objects hitting each other. Collisions transfer energy converting large scale movement (kinetic energy) into small scale movement (heat).
Answer:
Approximately
.
Explanation:
This question can be solved using Hess's Law.
Start by considering: how can the first three reactions (with known
values) be combined to produce the reaction
?
Here's one possible combination:
- Include the first reaction once, without inverting.
- Invert the second reaction and include it once.
- Include the third reaction after multiplying all its coefficients by two.
In other words, if
,
, and
denote the three reactions with know
values, respectively, then
will give the required reaction
.
By Hess's Law, the
value of the reaction
will thus be:
.
Answer:
Potential Energy is stored energy or energy of position (gravitational). The object isn't moving. For example, a ball being held is potential energy because the object isn't moving but it has the potential of turning into kinetic energy.
Kinetic Energy is the energy of motion. For example, running. You are moving, and there is clear action and activity
The path of energy flow from the sun to the humpback whale is as follows:
- Sun---> Plankton ---> Small fishes ---> Humpback whale.
<h3>What is energy?</h3>
Energy is the ability to do work.
The primary source of energy on the earth is the sun.
The energy from the sun is used by producers to produce food on which other organisms depend on.
The energy from the sun gets to the humpback whale through producers such as plankton.
The path of energy flow from the sun to the humpback whale is as follows:
- Sun---> Plankton ---> Small fishes ---> Humpback whale.
