Answer:
3 Ca(OH)2 + 2 K3PO4 ---> Ca3(PO4)2 + 6 KOH
Explanation:
Just balance each atom on both sides.
<span>Answer:
Moles HgO = 10.36 g/ 216.59 g/mol= 0.048
the ratio between HgO and O2 is 2 : 1
moles O2 formed = 0.048/ 2= 0.024
at STP one mole of any gas occupies 22.4 L
Volume O2 = 0.024 x 22.4 L/mol = 0.54 L</span>
Answer:
B) a neutron
Explanation:
The mass of a proton is approximately the mass of a neutron.
Both a neutron and proton are nuclear particles that are found within the nucleus of an atom.
Protons are the positively charged particles within an atom.
Neutrons do not have any charges on them.
Approximately the mass of:
Protons = 1.67 x 10⁻²⁷kg
Neutrons = 1.68 x 10⁻²⁷kg
