Answer:
A star is made up of burning gases, while a comet is made up of ice, gases, rocks, and dust.
Explanation:
Answer is: Benzene is trigonal (or triangular) planar.
VSEPR theory (The Valence Shell Electron Pair Repulsion Theory) uses the AXE notation (m and n are integers, m + n = number of regions of electron density).
For benzene molecule (C₆H₆):
m = 3; the number of atoms bonded to the central atom.
n = 0; the number of lone pairs on the central atom.
<span>Many scientists are studying tiny particles called nanoparticles. Since science is mainly done by working together (collaboration), I think the following best describes how the scientists are probably trying to learn about these particles:</span><span>
(A) The scientists come from varying backgrounds. They are asking different questions and designing different experiments to answer the questions.</span>
Answer:
75% of Cl-35 and 25% of Cl-37
Explanation:
Equation to find the mass number of an element. repeat the brackets for however many isotopes it has.
You can try guess it because 35.5 is closer to 35 than 37 so it has a higher abundance of Cl-35
also known as heavy hydrogen) is one of two stable isotopes of hydrogen (the other being protium, or hydrogen-1). The nucleus of deuterium, called a deuteron, contains one proton and one neutron, whereas the far more common protium has no neutron in the nucleus.
