Answer : The specific heat of tungsten is,
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of tungsten = ?
= specific heat of water =
= mass of tungsten = 19.5 g
= mass of water = 78.5 g
= final temperature =
= initial temperature of tungsten =
= initial temperature of water =
Now put all the given values in the above formula, we get
Therefore, the specific heat of tungsten is,
Answer:
It emits energy since to move from a higher energy level to a lower energy level or ground state, it must lose energy.
1 hectoliter is 26.4172
1 kiloliter is 264.172
Answer:
(Z)-4-methyl-2-pentene
Explanation:
Hydrogenation is a syn addition. This implies that the hydrogen atoms add to the same face of the multiple bond.
Hence, if we have the alkyne, 4-methyl-2-pentyne which reacts with excess hydrogen in the presence of a platinum catalyst, we obtain (Z)-4-methyl-2-pentene since the hydrogen atoms add on the same side of the multiple bond.
