Answer:
4
Explanation:
your chosen answer is right as unsaturated mean contains double bond and 1st and 3rd is Wrong as Carbon only can have 4 bonds and 2nd is Wrong as it is saturated.
hope this helps :)

See explanation
Explanation:
Extraction has to do with the separation of the components of a mixture by dissolving the mixture in a set up involving two phases. One phase is the aqueous phase (beneath) while the other is the organic phase (on top). The solvents used for the two phases must not be miscible. Water commonly is used for the aqueous phase.
Ethanol is an important solvent in chemistry but the solvent is miscible with water in all proportions. As a result of this, ethanol is a poor solvent for carrying out extraction.
Hbro dissociate as follows
HBro---> H+ + BrO-
Ka= (H+)(BrO-) / HBro
PH = -log (H+)
therefore (H+) = 10^-4.48= 3.31 x10^-5
ka is therefore= ( 3.31 x 10^-5)^2/0.55=1.99 x10^-9
Answer:
0.93956kg
Explanation:
Equation for the reaction is given as;
P4 + 5O2 --> P4O10
From the equation, 1 mole of P4 produces 1 mole of P4O10.
Mass = Number of moles * molar mass
Mass of P4 = 1 mol * 123.88 g/mol = 123.88 grams
Mass of P410 = 1 mol * 283.886 g/mol = 283.886 g
This means 123.88 grams of P4 produced 283.886 g of P4O10.
How many kilograms of P4O10 would be produced from 410. g of pure P4 ?
123.88 = 283.886
410 = x
x = (410 * 283.886 ) / 123.88
x = 939.56g
Upon converting to Kilogram by dividing by 1000
x = 0.93956kg
