Answer:
96.92 K
Explanation:
Applying,
V/T = V'/T'..................... Equation 1
Where V = Initial Volume, T = Initial Temperature, V' = Final Volume, T' = Final Temperature.
Make T the subject of the equation
T = VT'/V'................. Equation 2
From the question,
Given: V = 268 mL, V' = 824 mL, T' = 25°C = (25+273) = 298 K
Substitute these values into equation 2
T = (268×298)/824
T = 96.92 K
Hence the Initial temperature of Nitrogen gas is 96.92 K
Answer:
[A] = 1.438M = 1.4M (Two s.f)
Explanation:
Rate constant, k = 0.00317
Initial Concentration, [A]o = 1.44M
Final Concentration, [A] = ?
Time, t = 0.240 s
Since this is a second order reaction, the formula for this is given as;
1 / [A] = 1 / [A]o + kt
1 / [A] = 1 / 1.44 + (0.00317 * 0.240)
1 / [A] = 0.6944 + 0.0007608
1 / [A] = 0.6952
[A] = 1.438M = 1.4M (Two s.f)
The correct order of increasing surface tension at a given temperature, CH(OH)CH₂ OH >CH₃CH₂CH₂OH>HOCH₂ CH₂ OH>HOCH₂
With higher intermolecular pressures, a molecule's surface tension rises. Here, every molecule that is there has a hydrogen bond. It is well known that as the number of O-H bonds in a given molecule increases, so does the degree of hydrogen bonding. Strong intermolecular forces are thought to exist in molecules with more H-bonds. Due to the hydrogen bonds between water molecules, it has the highest surface tension of any liquid, save for mercury. Water molecules near the liquid's surface that are in contact with air are held tightly together by surface tension to create an imperceptible film.

Magnesium is a metal in group 2 of the periodic table in period three with a valency of 2 and reacts by loosing electrons. Magnesium cannot react with Aluminium because both of them are metals and react by loosing electrons thus no bond would be formed between them. Neon is a noble gas with an octet configuration thus will not react with magnesium. However, Magnesium will react with chlorine which is a non metal and reacts by gaining an electron thus forming an ionic bond.
