There would be 0 Potential energy, which eliminates A. There would be Spring energy, which eliminates C. So B and D are your 2 choices. Since the child is not moving just before the jump, there would be 0 Kinetic energy. So D.
Answer:
9-10 ppm.
0.2-0.4 ppm.
Explanation:
The proton on the aldehyde group will appear at approximately 9-10 ppm whereas the methylene peak on the alcohol is the only peak 0.2-0.4 ppm for either compound. Aldehydes and aromatics are quite distinctive in the Nuclear magnetic resonance (NMR). Aldehydes show up from 9-10 ppm, usually as a small singlet; aromatic protons show up from 6.5-8.5 ppm. NMR spectroscopy is the use of NMR to study the physical, chemical, and biological properties of matter.
Answer:
c.
Explanation:
it is c.-1 because oxidation number of cl is-1
Answer:
n = 4678.13 mol
Explanation:
Given data:
Temperature = 21°C
Pressure = 746 mmHg
Volume = 115 m³
Number of moles = ?
Solution:
21+273 = 294 k
746 /760 = 0.982 atm
115×1000 = 115000 L
PV = nRT
n = PV/RT
n = 0.982 atm × 115000 L /0.0821 atm. L. K⁻¹. mol ⁻¹× 294 k
n = 112930 atm. L/24.14 atm. L. mol ⁻¹
n = 4678.13 mol
