Which of the four basic substances on this ph scale is slightly basic? a. calcium hydroxide strike reset b. human blood strike reset c. whole milk strike reset d. lemon juice strike reset?

The answer is B. The human blood of a healthy person should range between 7.35 and 7.45. This is slightly basic since neutral pH is usually 7.0. Calcium hydroxide is too basic (could go up to pH 12), while whole milk ranges at pH 6.5 and lemon juice is approximately of pH 2.2.

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.

characterization of nanoparticles is a critical step in nanomaterial production as it provides information of dimension, morphology, surface charge, distribution and degree of surface functionalization.
