Answer:
.234 M
Explanation:
Molarity, or concentration, of a substance is simply found by dividing the amount of that substance in moles by its volume. Here, we are given the mass (in grams) of Kool-Aid, so we need to convert that to moles. To do this, we simply need the chemical formula of Kool-Aid, which I have found to be C12H22O11. The molar mass of C12H22O11, using the periodic table, is 342.296 g. Next, take this molar mass and divide the given mass of Kool-Aid by it. You then get about .234 mol Kool-Aid.
Lastly, divide this by the volume of 1.0 L. You get .234 M as your final molarity.
I believe the correct answer from the choices listed above is option A. The statement that best describes the use of chemical indicator in a titration would be that it measures the quantity of acid dissolved in water designated by molarity. <span>A </span>titration<span> is a method of analysis that will allow you to determine the precise endpoint of a reaction .</span>
Answer:the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
Explanation:
20 calories equals to 8.368 joules.
4.184 J is needed to raise 1 gram of water.(Heat capacity of water)
for 2 grams of water 8.368 joules.
So the answer is 16 c.
Answer:
Hydrogen atoms fuse together to form helium atoms. This releases a huge amount of energy in the form of Kinetic energy of the alpha particle and Electromagnetic radiation.
Explanation:
Nuclear Fusion is the Nuclear process in which the energy is produced when two lighter elements are collided together which are having some kinetic energy in them after that the two lighter nuclei will fuse together into a single heavier nuclei. This is opposite to what happens in Fission process in which the breaking up of atomic specie happens.
Both Nuclear Fission and Nuclear fission occurs with the release of massive amount of energy.
There are conditions for nuclear fusion to happens like, it requires 100 million's kelvin of temperature, also fusion will occur when the pressure is very high because increased pressure will result into squeezing of the atomic specie and hence they will fuse.
When the Hydrogen atom fuse together to form helium atoms. This release a huge amount of energy in the form of Kinetic energy of the alpha particle and Electromagnetic radiation.
