matter changes in various ways when food is prepared. the list below shows four of these changes.\n1. sugar is stirred in water until it dissolves.\n2. water boils until its volume is reduced by half.\n3. bubbles form when baking soda is mixed into vinegar.\n4. the clear part of an egg is whipped until it is fluffy and white.\nwhich of these changes is most likely a chemical change?\na 1 because the sugar disappears in the water\nb 2 because the volume decreases as the water becomes a gas\nc 3 because a gas forms that is released as bubbles\nd 4 because the egg color switches from clear to white
Answer
# Answer:
C. 3 because a gas forms that is released as bubbles
# Brief Explanations:
Una reacción química implica la formación de una nueva sustancia. En el caso 3, la reacción entre el bicarbonato de sodio y el vinagre produce dióxido de carbono (gas), lo que es una señal de un cambio químico. En 1, es una disolución (cambio físico). En 2, es una evaporación (cambio físico). En 4, es una emulsión (cambio físico).
