Avogadro Number of molecules is contained in 1 mole of water
6.02 * 10²³ molecules are contained in 1 mole of water.
2 * 10²² molecules will contain: (1* 2 * 10²²) / (<span>6.02 * 10²³)
</span>
≈ 0.0332 mole of Water.
The key difference between alkali and base is that the group 1 elements are categorized as alkali elements whereas any element or compound having basic properties are categorized as a base.
Answer:
the wrong statement is
d) the order of conductivity for different states is gas > liquid > solid
Explanation:
- the correct order is solid > liquid > gas
the thermal conductivity is a property of materials that it values the ability to transmit heat through them. In general, for metals and solid of continuos bodies the conductivity is high.
k = q / ΔT
∴ q: heat flux
∴ ΔT; temperature gradient
When a material undergoes changes of states, the thermal conductivity can change. for example, the conductivity of frozen water (a 0°C) is higer than that of liquid water.....from literature.
Answer:
47.5 mL
Solving:
M1 = 4.00 M
V1 = ?
M2 = 0.760 M
V2 = 0.250 L
---
M1 * V1 = M2 * V2
V1 = ( M2 * V2 ) / M1
V1 = ( 0.760 * 0.250 ) / 4.00
V1 = ( 0.190 ) / 4.00
V1 = 0.0475 L
Using the Boyle's law, the volume of the gas at 15 Km is .
<h3>What is Boyle's law?</h3>
Boyle's law states that, the volume of given mass of gas is inversely proportional to its pressure at constant temperature. Since pressure decreases with height, the volume will increase at higher altitude.
Initial volume = 10.0
Initial pressure = 1.00 atm
Final pressure = 0.350 atm
Final volume = ?
Using;
P1V1 = P2V2
V2 =
V2 =
V2 =
