Answer:
this is fairly simple if you have a periodic table with you.
Explanation:
atomic number 17 is Cl mass numer is 35.45 for protons neutron and electron you can just look that up on google. atomic number is where it is at on the periodic table and the mass number is in the little square at the bottom.
<span>The law of conservation of mass states that a mass of an object or the amount of matter composed inside an object or thing will not change unless it is added or removed of the matter that is contained in the object itself.
This means that for example, when you're bag has a mass of a 1kg, and you filled it with clothes it will jump its mass from 1kg to possibly 5kg, hypothetically. Thus, withoout the object or clothes that was added the weight of the bad wouldn't change and vice-versa.

Answer:
B. The temperature of object A is higher than that of object B.
Explanation:
Thermal energy always transfers from hotter object to colder one. Temperature indicates the hotness and coldness of a body. In a hotter body, molecules move faster and thus, their average kinetic energy would be greater.
If thermal energy will transfer from object A to object B, then the temperature of object A would be higher than that of object B. Also, its molecules would move faster and would have greater average kinetic energy.
