Trini adds 10 g of baking soda to 100 g of vinegar. the mixture begins to bubble. when the bubbling stops, trini finds the mass of the resulting mixture. she determines that the mass is 105 g.

how do you know that a chemical change has occurred?

mass was destroyed when vinegar reacted with baking soda.
mixtures are always less massive than their parts.
the substances reacted, producing gas.
vinegar evaporated during the experiment.

they are made of gases.

they have a spherical shape.

they make energy through fusion.

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.
