Answer:
52.17%
Explanation:
COCl2.6H20
C=12,O=16,Cl=35.5,H=1
Relative molecular mass of COCl2.6H2O= 12+16+71+6(2+16) = 99 + 108= 207g
Relative molecular mass of 6H2O = 108g
Percentage of water = (108/207 )*100
= 52.17%
Answer:
C2H6O + 3O2 —> 2CO2 + 3H2O
Explanation:
Answer:
not a reason? if you ask a reason ,i can say An actual yield is the mass of a product actually obtained from the reaction. It is usually less than the theoretical yield. The reasons for this include:
-->incomplete reactions, in which some of the reactants do not react to form the product
practical losses during the experiment
->side reactions (unwanted reactions that compete with the desired reaction)
->reversible reactions
->impurities in reactants
but you asked for not reason then it can be anything lul, like balanced chemical equation, rate of reaction and etc etc ✌️;)
I have no idea honestly I don’t remember I had it and I forgot it
The concept we are looking for here is electronegativity. This concept is a measure of how strong an atom or element can attract a pair, that is bonding, of electrons to itself.
Fluorine is the element or atom of the greatest electronegativity. Electronegativity would increase as we move left to right of the periodic table.
