I would say the water is the solvent and carbon dioxide is the solute. Carbon dioxide is usually introduced to water under pressure and then sealed. Once the cap is removed, the carbon dioxide starts to escape since it is then under low pressure. Sometimes, natural groundwater has dissolved carbon dioxide in it but most of our soft drinks have it artificially introduced. Water plus carbon dioxide also form carbonic acid and this can give the tingly sensation on the tongue when drinking soft drinks.
Answer:
There is a 1:1 neutralization reaction, so, number of moles:
0.085 l * 0.900 mol/ L = 0.0765 mol HCL
The heat produced: 0.0765 mol * -56.2 kJ/mol = -4.229 kJ (this is the heat of neutralization)
Change in temperature: The mass to use in the equation Q=cmT.
4229 J / (4.186 J/gC*170 g) = 6.042 C
Add to the initial temperature:
18.24 + 6.042 = 24.29 C°
Answer:
Viscosity increases with stronger intermolecular forces
Step-by-step explanation:
<em>Viscosity</em> is the resistance of a liquid to flow.
A liquid can flow easily only if the molecules can move past each other with little resistance.
If there are strong intermolecular attractive forces among molecules, it is more difficult for them to move past each other.
For example, the molecules in molasses have strong attractive forces, so it is quite viscous.
To compute for grams of fat in each salad:
We know that, A = C.
And B is 5 grams more, so it is B = 5 + A
And the total fat is 65, so A + B + C = 65 grams.
Computation:
A + (5 + A) + A = 65
3A + 5 = 65
3A = 60
A = 20
A = 20
B = (65 - 40) = 25
C = 20
Answer:
6 moles
Explanation:
3 moles of O2 produce 2 moles of Al2O3 so in order to produce 4 moles pf AL2O3 you need 4 x 3 /2 moles of O.
