Answer: law of conservation of matter states that mass in an isolated system can neither be created nor destroyed by chemical reactions or physical transformation.
thus, the mass of the reactants in a reaction must be equal to the mass of the products
The formula to convert from Celsius to Fahrenheit is F = 9/5C + 32 or F = (C*1,8)+32
F = 9/5*39 + 32 = 70,2 + 32 = 102,2° F
Heat of vaporization (During which the temperature stays the same)
Answer:
It would be a heterogeneous mixture.
The first part of Dalton's model is that all matter is made of atoms, and these atoms are indivisible.
The second part of this model is that atoms of an element have identical masses and identical propertes.
At last, the third part of Dalton's model is that all compounds are formed by two or more different type of atoms combined.
