When 86.7 of water at a temperature of 73.0 C is mixed with an unknown mass of water at a temperature at 22.3 C final temperature of the resulting mixture is 61.7 C. What was the mass of the second sample water

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products

i believe it is 40–40–20%

explanation:

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.

hope i !
