I don't understand your question....
thank you
Answer:
CH2 is the chemical name for methylene and belongs to the general compound category of Alkenes. It comprises of a single carbon atom bonded with 2 hydrogen atoms . The general formula for alkenes is C(n)H(2n) with n denoting the number of carbon atoms and thus deciding the name of the compound.
Explanation:
Flame (fire) is the effect of a chemical reaction that produces visible light and heat. The chemical reaction is going on in the substance being burned.. Thats why coals glow and flames seem to leap into the air.
<span>If your reaction does not have a flame, then either it is not producing visible light or the reaction does not occur in the air above the substance.</span>
Answer:
Actually there is no answer but there is so much theories but people mostly says Bug Bang
When the balanced reaction equation is:
P4O10 + 6H2O→ 4 H3PO4
when we have the mass of P4O10 = 10 g and the molar mass of P4O10=284 g/mol & we have the molar mass of H3PO4 =98 g/mol so we can get the mass of H3PO4 by substitution by:
mass of H3PO4 = (mass of P4O10)/(molar mass of P4O10) * 4(mol of H3PO4)*molar mass of H3PO4
∴mass of H3PO4 = (10 / 284) * 4 * 98 = 13.8 g
