Answer:
Ionic compounds are compounds whereas metals are elements. Ionic compounds are electrolytes whereas metals are conductors. Ionic compounds are brittle whereas metals are malleable and ductile. ... Most ionic compounds will dissolve in polar solvents like water whereas metals will either be insoluble or react with water.
This is combustion
CH4+2O2---> CO2 +2H2O
Answer:
because the hundreds of ghosts could kill them.no.no.yes
Answer:
C) 0, +5
Explanation:
P + H2O + HNO3 -> H3PO4 + NO
We consider all compounds that contain phosphorus in the equation
A substance that has no charge has a zero oxidation state
Hence at the reactant, phosphorus has an oxidation state of 0
Let us consider H3PO4 at the product side
Oxidation state of
H =+1×3=+3
O=-2×4=-8
P = ?
H3PO4 is a neutral compound and has 0 oxidation state
The sum of the individual oxidation states of each atoms in H3PO4 is equal to 0
Hence,
+3 + P + (-8) = 0
3+P-8=0
P=-3+8=+5
Hence the oxidation state of phosphorus in H3PO4 is +5
Therefore, the oxidation state of P in the reaction changed from
0 to +5
Phosphorus is said to have undergone oxidation
