Answer:
CH3+
Explanation:
Sp2 hybridization involves the mixing of on s and two p orbitals. This is observed in CH3+. The ion is trigonal planar with a H-C-H bond angle of 120°.
The anion, CH3^- is sp3 hybridized, hence only CH3+ is sp2 hybridized among the options.
Answer: How many grams are in 2.5 moles of N2?
Explanation: 1 mole is equal to 1 moles N2, or 28.0134 grams.
One mole of N2 molecules would have a mass of 2 X 14.01 g = 28.02 g.
Answer:
Energy transfers from the metal to the water and calorimeter until they are all at room temperature.
Explanation:
Calorimetry is the process that is used to determine the amount of heat that has been transferred in any process. In any chemical or physical process, the amount of energy is required. This energy is measured by the process of calorimetry. A calorimeter is a device that is used in this process. The heat that has been used in the process is measured and the change in the temperature is noted.
This is a build up of lava which came out of the volcano in previous eruptions, once this lava came out of the volcano it cooled and hardened, over many eruptions layers of hardened volcanic rock will form. The layers are slanted as gravity acts on the lava so it flows down and a little further from the cone.
the degree of compactness of a substance.
