Answer:
As per Dalton's law of Partial pressure,
The total pressure of a mixture of gases is equal to sum of partial pressure of individual components of the mixture.
So, P=P_H+P_N+P_WP=P
H
+P
N
+P
W
\implies 864\ mm=220\ mm+410\ mm+P_W\implies⟹864 mm=220 mm+410 mm+P
W
⟹ P_W=864-630=234P
W
=864−630=234 mm of Hg.

You can infer that the size of sugar particles that are dissolved in a mixture of sugar and water are very small since you cannot see the sugar particles. Sugar is an organic compound which is held by covalent bonding. When we dissolve sugar in water, it does not ionizes or dissociates rather it stays as a sugar molecule dissolved in the solvent which is water. These particles are very which is impossible to be seen by the naked eye. Dissolution involves the solute particles and solvent particles interacting and attracting each other forming a solution. Sugar molecules are attracted to water since it is a polar molecule.
Answer:
true
Explanation:
drought is a period of unusually persistent dry weather that persists long enough to cause serious problems such as crop damage and/or water supply shortages. The severity of the drought depends upon the degree of moisture deficiency, the duration, and the size of the affected area.
Since neon has 8 valence electrons, a full octet makes neon stable. It is also a noble gas. Then, you do the configuration...
1s2 2s2 2p6
2s holds 2 valence electrons while 2p has 6 that equals a full octet.
Answer:
Explanation:
Use the ideal gas equation:
Where:
- p is the pressure: 202.6kPa
- n is the number of moles: 0.050 mol
- T is the temperatue in absolute scale: 400K
- R is the universal constant for ideal gases: 8.314 L-kPa / K-mol
- V is the volume
Substitute and solve for V:
Convert to liters:
The answer is rounded to two significant figures.
