Answer:
The air molecules that are surrounding the metal will speed up, and the molecules in the metal will slow down.
Explanation:
As molecules heat they begin to move faster. The heat from the metal plate will make the molecules at room temperature move faster. And the room temperature makes the hot place cool, making the hot plate molecules slow down.

Answer:
B. (Linear graph with positive slope)
Explanation:
The picture above showing that
1. T2 is higher than T1
2. V2 is higher than V2
From this, we can conclude that the relationship for temperature (T) and volume(V) is positive. That means a higher temperature will result in a higher volume.
Since the relationship positive, the graph will have a positive slope. We can't prove if the graph should be linear or exponential since we don't have the exact number of the experiment.
Answer:
A) Ethanoic acid and ammonium chloride.
Explanation:
Amides go through acid hydrolysis to produce carboxylic acid and ammonia by heating in aqueous acid. The acid hydrolysis reaction is produced through the <u>nucleophilic addition of water to the protonated amide</u>, then comes the transference of a proton from the oxygen to the nitrogen to make nitrogen a better leaving group, and finally, the subsequent elimination (see attachment).
In this case, the products formed with the reaction of ethanamide and aqueous HCl will be <u>ethanoic acid and ammonium chloride</u>.
Explanation:
CH4 + 2 O2 -> CO2 +2 H2O
4 H3N+3 O2 -> 6H2O + 2 N2
Answer:
Volume occupied by 10 grams of Lithium Oxide at STP is 7.52 L
Explanation:
STP (Standard Temperature and Pressure) : It is used while performing calculation on gases and provide standards of measurements while performing experiment.
According to IUPAC (International Union of Pure And applied Chemistry) , standard temperature is 273.15 K and Pressure is 100 kPa (0.9869 atm). At STP condition 1 mole of substance occupies 22.4 L volume .
Molar mass of Lithium Oxide = 29.8 g/mol
= 2(6.9) + 15.99 = 29.8
Mass of 1 mole = 29.8 g
1 mole occupies, Volume = 22.4 L
29.8 g occupies, V = 22.4 L
1 g occupies ,V =
1 g occupies ,V = 0.7516 L
10 g tex]Li_{2}O[/tex] occupies ,V = L
V = 7.52 L
So, volume occupied by Lithium Oxide At STP is 7.52 L
