Answer:
We expect the enthalpies of combustion of two isomers to be different.
The molecular formular of the two molecules are very similar.
So the balanced chemical equation for the two combustion reactions are the same.
Explanation:
In calculation of the combustion enthalpiesfrom the isomers of the products and reactant.
The difference will be in the standard enthalpies of formation of the two combustion products.
The rod-shaped n- octane has vibrational and rotational motion possible more than the almost spherical neoprene.
The answer is (4). The same magnitude and the opposite sign. For a proton, it has one positive electric charge. And for electron, it has one negative electric charge. So they have same magnitude but opposite sign.
OP already did it - CONGRATS!!
here are the steps 2 get the same ans:
(NH4)2 CO3 has 2x N, 8x H, 1x C and 3x O per molecule
so its molecular mass = 2x14 + 8x1 + 1x12 + 3x16
=28+8+12+48
=96g
of that 96g, 8x1=8g is due to Hydrogen
so by ratio n proportion, 1.00g will have 1x8/96 = 1/12g = 0.083g of H
<span>1) osmotic pressure exerted by a solution is equal to the molarity multiplied by the absolute temperature and the gas constant r.
Call: P = osmotic pressure; C = molarity; T = absolute temperature
=> P = C * T * r
2) </span><span>write an equation that will let you
calculate the molarity c of this solution. your equation should contain
only symbols. be sure you define each symbol other than r.
</span><span>
</span>=> C = P / (rT)
Answer: C = P / (rT)
The initial report of the team formed by PURE may contain findings similar to the processes used in the disinfection of the water. Usual cases of ammonia presence in water are due to chloramine disinfection process. Also, they should also look into the storage of their facility and the end user which may also have a window of contamination.
