Which of the following statements pertaining to an SN2 reaction is INCORRECT? (1) The nucleophile attacks the carbon from the side of the molecule opposite the group being displaced, that is, opposite to the leaving group. (2) The rate of the reaction is dependent of the concentration of the nucleophile. (3) The reaction proceeds with simultaneous bond formation and bond breaking. (4) Bulky groups around the reaction site speeds up the reaction

The Calvin cycle is considered blank because it doesn’t involve photoexcitation

Are the following judgments about the properties of iron correct?

A. Iron reacts with dilute nitric acid.

B. In cold concentrated sulfuric acid, iron is passivated.

In some areas, drinking water is fluoridated to reduce tooth decay. The maximum acceptable concentration (MAC) of fluoride ions in drinking water is 1.50 ppm.

In Dublin, California, a malfunction occurred in the fluoridation equipment caused fluoride levels to rise as high as 200 ppm. This resulted in many people becoming ill. 

During the malfunction, 673 kg of fluoride ions where injected into a storage tank of water. Given that the resulting concentration was 200 ppm, calculate the volume, in ML, of the water storage tank.
