Answer:

2 Fe + 3 Br₂ → 2 FeBr₃

Explanation:

There are 2 Br atoms on the left, and 3 on the right. So put a 3 in front of Br₂, and a 2 in front of FeBr₃.

_Fe + 3 Br₂ → 2 FeBr₃

Now there's 6 Br atoms on each side. There are 2 Fe atoms on the right side, so put a 2 in front of Fe:

2 Fe + 3 Br₂ → 2 FeBr₃

Now the equation is balanced.

In this lab you will use a cart and track to explore various aspects of motion. You will measure and record the time it takes th

It is given that by using track and cart we can record the time and the distance travelled and also the speed of the cart can be recorded. With all this data we can solve questions on the laws of motion.

Like using the first law of motion we can determine the force of gravity acting on the cart that has moved a certain distance and the velocity or the speed of card has already been registered and since time is known putting the values in formula would help us calculate the gravitational pull acting on cart.

To solve this problem we will begin by finding the pressure through density and average depth. Later we will find the Force, by means of the relation of the pressure and the area.
