It is a star, since it glows and is very hot.
C is the correct answer. Calcium chlorate is aqueous but barium sulfide forms a precipitate, so a reaction would occur
Answer:
answer is b
In order to balance out the equation, you bed to double the amount of H atoms you have and the number of CL atoms. to do this you put a 2 infrount of the HCL
According to the law of conservation of mass (mass remains the same throughout a reaction), mass is conserved in this case. This can be proven by comparing the weight of two enclosed glass containers of the reaction. They will most likely have the same weight because the products the chemical reaction creates would most likely produce a gas which can be trapped if there is no opening in the glass container. To further investigate, compare the weights of the products of the reaction with an enclosed container to another container with no lid of the same reaction.
