I NEED HELP PLZZ THX <3 Question 16
A hockey puck is hit with a large force. The puck moves at a high speed as it slides over the ice.

What happens according to Newton’s first law of motion?

A) The puck does not lose any speed because ice is a very slippery surface.

B) The puck gradually slows down because mass makes objects slow down.

C) The puck gradually slows down because friction would be acting on it.

D) The puck does not lose any speed because once an object starts moving, the force of friction would no longer apply to it.

C) The puck gradually slows down because friction would be acting on it.

Explanation:

It would be C because the puck would be scraping the ice and when it's scraping it slowly losses its speed because the ground is pushing it lightly

Hoped that helped :/

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8  

mgco3-5h2o"

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
