Answer:
We know that kinetic energy is one of the forms of internal energy, so the release of heat from an object causes a decrease in the average kinetic energy of its particles.
Answer:
Thus, helium has the largest first ionization energy, while francium has one of the lowest.
Answer:
D. All of the above
Explanation:
E = MC² is a common equation in physics.
E is energy
M is mass
C is the speed of light
The law was stated by Albert Einstein.
- From this law, it was shown that energy is released when matter is destroyed.
- Mass and energy are equivalent as seen in nuclear reactions where mass is converted to energy.
- Mass and energy is usually conserved in any process and this is a subtle modification of the law of conservation of matter and energy.
- Most of these postulates apply to nuclear reactions which generally do not follow some precepts of chemical laws.
H = 1 amu
P = 31 amu
O = 16 amu
Therefore:
H3PO4 = 1 x 3 + 31 + 16 x 4 => 98 u
hope this helps!
Answer:
It is important to analyze data to further understand what's going on. By analyzing data, you know more about what you are investigating. Without analyzing data, you may find it harder to figure something.
