Answer:
heptan-3-one and heptan-2-one
Explanation:
In this case, we must remember what the products of this reaction are. An alkyne in the presence of HgSO4 and H2SO4 will produce a ketone. But, in the triple bond, we have two carbons, therefore the carbonyl group can be placed on any of the carbons of the triple bond.
In figure 1 we have the general reaction. At C = O it can be added to the carbon on the left (red carbon) or the carbon on the right (blue carbon).
Following this logic, for 2-heptyne the carbonyl group can be added to carbon 2 producing <u>heptan-2-one</u>. Similarly, the carbonyl group can be added to carbon 3 producing <u>heptan-3-one</u>. (See figure 2)
Satellite, also called artificial satellite, is a computer-controlled machine or objects that is launched into the space by a rocket, called the launch vehicle and placed in the orbit of a celestial object.
The kinetic-molecular theory explains the properties of the gases in terms of energy, size and motion of their particles.
The assumptions that the kinetic-moletuclar theory makes about the characteristics of gas particles are:
1. Gases are constituted by a large amount of particles (atoms or molecules) symilar to solid spherical sphers, in constant and random motion.
2. Gas particles move in straight line until collide with another particle or the walls of the vessel.
3. Gas particles are so small compared to the distances that separate them, that the volume of the gas is considered empty space: the volume of the particles is neglected.
4. Beside the already mentioned collisions with the walls of the vessels or between the particles, there is no interaction (attractive or repulsive forces) acting on the gas particles.
5. The collisions between gas particles or with the walls of the vessel are elastic: there is not loss of energy.
6. The average kinetic energy of the particles in a gas depends only on the absolute temperature of the gas: at a given temperatue every gas have the same average kinetic energy.
That collection of assumptions are used to explain such things as: the relation of pressure withthe number of particles, the relation of pressure and temperature, the relation of pressure and volume, the relation of volume and temperature, Avogadro's hypothesis (relation of volume and number of particles), Dalton's Law of partial pressures, and both effusion and difusion.
Answer:
Mass of iron = 59.375 gm
Explanation:
Calories ( or joules) are added to the water by the hot steel so at the endpoint they are BOTH at 40 C
The water gains:
4.18 j/g-C * 50 * (40-30 C) = 2090 j
The steel gave up 2090 j going from 120 to 40 C
2090 = .44 j/g-C * m * (120-40) solve fro m = 59.375 gm
