A size force of 5N will be exerted on Artl's foot.
This is because Newton's third law of motion, where in which an action occurs, a reaction will occur with the same amount of force, but reversed towards the direction of the area where the action occurred.
<u>Answer:</u> The moles of hydrochloric acid is 
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:

Or,

We are given:
Molarity of solution = 0.5173 M
Volume of solution = 
Putting values in above equation, we get:

Hence, the moles of hydrochloric acid is 
Answer:
There are many properties that differentiate metals from non-metals. They are: Luster, conductivity of heat and electricity, physical strength i.e. Brittle or difficult to break, etc.
