Answer:
B is the answer.
Explanation:
If you've ever dropped something in water, or done an experiment like that, you would know. The force of gravity pulling the object down while its still in the air, once the object hits the water, its all up to density to see if it goes to the top, or goes/stays at the bottom.
Answer:
a chemical change is when the substance turns into a new substance and can not be changed back into its original form
Explanation:
To determine which has the greatest mass, we need to find out the molecular mass of each element:
Uranium (U) = 238 g/mol
Oxygen (O) = 16 g/mol
Sodium (Na) = 23 g/mol
Chlorine (Cl) = 35.45 g/mol
Therefore, if we have one mole of each element, the element with the greatest mass is 238 grams or <u>Uranium.</u><span />
Water and carbon dioxide into food.
The correct answer for this statement would be FALSE. It is considered false since exothermic reactions release energy, therefore, this energy can be considered more of a product, instead of the reactant. Hope this is the answer that you are looking for.
