Here are some densities computed by a student doing this laboratory experiment. rock water wooden block 3.34 g/cm3 1.00 g/cm3 0.495 g/cm3 the student noticed that the rock sank in water. after the experiment, she put the wooden block in the water and it floated. use the densities above to explain why.

Explanation:

Density is defined as the mass of the substance present in the unit volume of the substance.

So, when the rock is immersed in the water the it sank because the density if the rock is greater than the density of water.

Where as wooden block float in the water because the density of the wooden block is less then the density of the water.

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.
