Answer:
diamonds are carbon based and have a giant covalent structure
Explanation:
This is what gives diamonds its strength and rigidity.
Diamonds are different from graphite due to the way the atoms are arranged
Answer:
AlF3
Explanation:
Aluminum fluoride is an inorganic compound of chemical formula AlF3. Such a compound originates from the treatment of aluminum hydroxide particles with hydrogen fluoride, which react and give rise to aluminum fluoride. This is a very important solid and crystalline element during the production of other compounds that use aluminum oxides because it has the ability to lower the melting point.
Answer:
C. Atoms have isotopes of an element have different numbers of protons.
Explanation:
The isotopes are the variation in the number of neutrons (neutral charge), with increases the weight of the atom, so the first one, is related to this one.
1s22s22p63s23p64s23d5 is the correct answer.
Hey there!
Mg + HCl → MgCl₂ + H₂
Balance Cl.
1 on the left, 2 on the right. Add a coefficient of 2 in front of HCl.
Mg + 2HCl → MgCl₂ + H₂
Balance H.
2 on the left, 2 on the right. Already balanced.
Balance Mg.
1 on the left, 1 on the right. Already balanced.
Our final balanced equation: Mg + 2HCl → MgCl₂ + H₂
Hope this helps!
