C15H32
should b the answer
The chemical formula for acido perbromico is HBrO4 or perbromic
acid or bromate. It is an inorganic compound and an oxoacid of bromine. When an
H+, the –ate ion is –ic acid: one less O is –ous acid, ttwo less is hypo- -ous
acid and one more is per- -ic acid.
Answer:
0.088mole
Explanation:
Given parameters:
Mass of the compound = 5.125g
Unknown:
Number of moles = ?
Solution:
To solve this problem, we need first find the molar mass of the given compound.
Molar mass of NaCl = 23 + 35.5 = 58.5g/mol
So;
Number of moles = = = 0.088mole
Answer: An atom that has gained an electron.
Explanation:
The number of protons in an atom cannot change except for some exceptional circumstances.
Cations (or metal ions) are formed when atoms lose electrons, as they want to form a complete outer electron shell to become as stable as possible.
For example, potassium is a 1+ ion, because it has one electron in its outer shell (and in group one). Therefore, to become more stable that electron is lost to become an ion or cation. As one electron is lost, the potassium cation charge is 1+ as the charge of an electron is 1-.
Answer:
2 KOH → H₂O + K₂O
Explanation:
When KOH descomposes in potassium oxide, K₂O and water, H₂O.
The unbalanced equation is:
KOH → H₂O + K₂O
As you can see, 2 hydrogen, potassium and oxygen atoms are produced, to balance this equation we can write:
2 KOH → H₂O + K₂O
This is the balanced equation because 2 atoms of K, H and O are in reactants and products
