I am accessible in most locations on Earth, but certain areas have much more of me. I am perpetually renewed and cause little or

no waste or pollution since I am not fuel. Technology used to harness/convert me is expensive and I still only work most of the day.

A 20 N object is placed on a surface and starts to slide. What is the MOST likely reason the object begins to move?
ra1l [238]

Answer:

c.

Explanation:

If the object starts to slide it must be on a slope.

There are 2 forces acting on the object - gravity and the friction between the object and the surface.

If sliding starts then the forces must be unbalanced.

The force of gravity is greater than the friction.

For the reaction, calculate how many grams of the product form when 14.4 g of Br2 completely reacts. Assume that there is more t
lora16 [44]

Answer:

The answer to your question is 21.45 g of KBr

Explanation:

Chemical reaction

                               2K + Br₂   ⇒   2KBr

                                       14.4            ?

Process

1.- Calculate the molecular mass of bromine and potassium bromide

Bromine = 2 x 79.9 = 159.8g

Potassium bromide = 2(79.9 + 39.1) = 238 g

2.- Solve it using proportions

              159.8 g of Bromine ------------ 238 g of potassium bromide                    

                14.4 g of Bromine  ------------  x

                        x = (14.4 x 238) / 159.8

                        x = 3427.2 / 159.8

                        x = 21.45g of KBr
