Answer:
Mixture.
Explanation:
Hello,
In this case, when blending we are continuously sliding the substances until we obtain small particles that when do not chemically but physically combine we say they are forming a mixture. Nevertheless, when they chemically combine they form a chemical compound due to the formation of bonds between them.
Regards.
Gas particles are in constant motion, and any object in motion has kinetic energy (Ek). ... For example, in the collision of two molecules, one molecule may be deflected at a slightly higher speed and the other at a slightly lower speed, but the average kinetic energy does not change.

Answer:
The correct option is C.
Explanation:
Nuclear and chemical reactions are two types of reactions that one usually encounter in chemistry. These two reactions differ from each other significantly. For instance, the nuclear reactions usually involve the nucleus of the involving atoms while chemical reactions has to do with the electrons that are located outside of the nucleus of the atoms. Also, it is only chemical reaction that are influenced by factors such as temperature, pressure, catalyst, etc. Such factors does not determine the rate of nuclear reactions.
To calculate this,
We know that energy is 1 photon
E = hc/wavelenth
wavelength of 10.0 m
Solution:
h = 6.626 x 10^-34 Jsec
C = 2.9979 x 10^8 m/sec
E = 6.626 10^-34 * 2.9979 10^8 / 10 = 1.9864 10^-26J
Then, the number of photons is computed by:
n = 1000 / 1.9864 10^-26 = 5.04 10^28 photons
Answer:
Blue litmus paper paper turns red under acidic conditions. Red litmus paper turns blue under basic or alkaline conditions. If you're using a universal indicator, the weak base should turn those blue.
