in an experiment, temperature and the amount of nacl dissolved in water were studied. researchers changed the temperature of the water to see its effects in the amount of. they conducted two test, one changing the temperature and another without changing the temperature. the temperature change affect the amount of nacl dissolved .in this experiment the dependent variable is?
a. the sample without a temperature change
b. the number of test
c. the amount of naci dissolved
d. the number of researchers
e. the temperature

C

Explanation:

The dependent variable is the variable that you measure and in this experiment, the amount of NaCl dissolved is what is being measured.

The correct answer is C. The amount of NaCl dissolved

Explanation:

In an experiment, you can identify the dependent variable because this is the factor tested or studied. Also, this variable is affected by the independent variable or factor manipulated by the scientists. This means, in the experiment presented, the independent variable is the temperature as this is manipulated, and therefore the dependent variable is the amount of NaCl dissolved because this depends on the independent variable and it is the main factor that is being tested.

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.
