For the molecule given below: HCN 1. Draw the Lewis Dot diagram for the molecule on a paper/ tablet/ ipad and write the question number. Use lines to represent bonds, and show all lone pairs as dots. If your molecule has 3D shape, make sure to use wedges and dotted lines. Write the number of valence electrons next to the drawing. Upload your work. Note: No credit will be given if the dot structure is incorrect. 2. Select the name that best describes the electron geometry/ electron pair geometry: [ Select ] 3. Select the name that best describes the molecular geometry/ molecular shape: [ Select ] 4. Select the closest bond angle(s) for the molecule (°): [ Select ]

please can you please do questions 7, 8 and 9 please I would really appreciate it if you can do all I would appreciate if you could do all  please answer super super super fast I really need it its really important answer fast this is not a graded question

Waht affect, if any would there be on a system efficiency if there were no need for 100% vapor refrigerant in the suction line to protect the compressor?

The important features of the adiabatic flask is it’s vaccum sealed hollow glass cylinder and _______.     Silver coated on both sides     Zinc oxide coated on one side     Siver coated on one side     Plastic coated on both sides     Painted white on outside surface

Screen reader description: The Ordinary Phases of Carbon Dioxide. Pressure (Pa) 10 to the power of 0 to 10  up to 10 to the power of 8 on Y-axis. Temperature in Kelvins 0 to 700 on X-axis. Curved line up from 105 K at 10 to the power of 0 Pa up to 200 K and 10 to the power of 6 Pa. The line forks here. There is an almost vertical line up to 10 to the power of 8 Pa, and a line that goes diagonally up and to the right to 325 K and 10 to the power of 7 Pa. To the left of the fork is "Solid". To the right of the fork is "Gas". In between the lines of the fork is "Liquid".  End of image. The tempterature closest to the triple point is:   0 K   100 K   200 K   300 K   400 K   500 K   600 K   700 K   100 Pa   101 Pa   102 Pa   103 Pa   104 Pa   105 Pa   106 Pa   107 Pa

A transmitting valve is cooled by water circulating through its hollow electrodes. The water enters the valve at 25°C and leaves it at 85°C. Calculate the rate of flow in kg/second needed per kW of cooling. The temperature of 1 kg of water is raised to 1°C by 4178 joules. a. 0.001 kg/s b. 0.002 kg/s c. 0.003 kg/s d. 0.004 kg/s
