Which of the following statements is correct with respect to electron spin? a. the two electrons in one orbital must have opposite spin. b. the two electrons in one orbital must have the same spin. c. the two electrons in one orbital can have either opposite or the same spin. d. the two electrons in one orbital repel each other if they have opposite spin. e. the two electrons in one orbital attract each other if they have the same spin.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

the answer is 1 i believe
