Answer:
Equation 2, because K being more reactive, exchanges position with Pb in PbNO3.
Explanation:
Answer:
36.63 Torr
Explanation:
You need to use two expressions, one for pressure and the other with the relation of density and height of the column.
For the pressure:
P = h * d * g (1)
h is height.
d density
g gravity
The second expression put a relation between the densities and height of the column so:
d1/d2 = h1/h2 (2)
let 1 be the phthalate, and 2 the mercury.
Let's calculate first the relation of density:
d1/d2 = 13.53 / 1.046 = 12.93
Now with the first expression, we can calculate the pressure so:
P = hdg
We have two compounds so,
h1d1g = h2d2g ---> gravity cancels out
From here, we can solve for h2:
h2 = h1*(d1/d2)
replacing:
h2 = 459 / 12.53
h2 = 36.63 mm
1 mmHg is 1 torr, therefore the pressure of the gas in Torr would be 36.63 Torr
In <span>c2h4o2 there are
2 atoms of carbon
4 atoms of hydrogen
2 atoms of oxygen
Hydrogen atomic masses is 1 which was very low so 4 of them would still be the lowest mass percent. Then we have carbon and oxygen which both have 2 atoms. Oxygen atomic mass is more than carbon atomic mass, so oxygen should contribute more mass percent composition. The sequence from higher mass percent composition should be:
1. Oxygen
2. Carbon
3. Hydrogen</span>
Answer:
A campfire is an example of entropy. The solid wood burns and becomes ash, smoke and gases, all of which spread energy outwards more easily than the solid fuel. Ice melting, salt or sugar dissolving, making popcorn and boiling water for tea are processes with increasing entropy in your kitchen.

The complete sentence of what applies is given as
- The more complex the size and shape of the molecules in a liquid, the higher the viscosity.
- The less complex the size and shape of the molecules in a liquid, the lower the viscosity.
This is further explained below.
<h3>What is
viscosity?</h3>
Generally, The amount of resistance that a fluid has to change shape at a certain pace is referred to as its viscosity.
When referring to liquids, it is synonymous with the more colloquial idea of "thickness"; for instance, the syrup has a greater viscosity than water.
In conclusion, The complete sentence of what applies is given as
- The more complex the size and shape of the molecules in a liquid, the higher the viscosity.
- The less complex the size and shape of the molecules in a liquid, the lower the viscosity.
