Consider the following chemical reaction: Mg (s) + ZnCl2 (aq) → MgCl2 (aq) + Zn (s) If the reaction started with 45.0 g of Mg and 297.6 g of Zinc Chloride and yielded 176.5 g of Magnesium Chloride, how much Zinc is in the product?

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?

a chemical change results in a new substance being formed; whereas a physical change will result in a different state of matter
