Select the correct newman projection using one of the tabs below, and drag the three groups (cl, br, and ch3) to their correct locations.

newmann projection displaying the conformation of chemical bond from front to back. In newmann projection, the front atom represented by dot and back atom represented by circle.

The given fly wedge structure is given indicating bromine is present in front of methane as both of them are coming out of the plane. Whereas chlorine is present in front of hydrogen as chlorine and hydrogen both are going in back direction. Hydrogen and methane both are present on plane and thus both are adjacent to each other in new mann projection.

The diagram for newmann projection is shown:

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
