Answer:
What best describes the concept of weight is the force on an object due to its mass and gravity.
Explanation:
Weight is the force with which gravity pulls a body or object towards the earth. It is a physical unit that involves both the force of gravity and the mass that an object has.
In general, the terms mass and weight are different, being the mass a characteristic of the body -without influence of other factors- and the weight is the force with which the gravity pushes the mass of that same body.
Regarding the other options:
- <em>The amount of space an object takes up
, corresponds to the volume of a body.</em>
- <em>The amount of matter in an object
, corresponds to the mass.</em>
- <em>The force on an object due to its speed and location, is related to the movement of a body.</em>
Answer:
= -457.9 kJ and reaction is product favored.
Explanation:
The given reaction is associated with 2 moles of 
Standard free energy change of the reaction (
) is given as:
, where T represents temperature in kelvin scale
So, 
So, for the reaction of 1.57 moles of
, 
As,
is negative therefore reaction is product favored under standard condition.
35g Mg x 1mol / 24g = 840 mol
A dipeptide is formed by the process of dehydration synthesis, which in this case allows two amino acids to come together and form a larger molecule plus water.
