<h2>\sf \pink{Question}</h2>

What is a positive acceleration ?

<h2>\sf \blue{Answer}</h2>

If the velocity of an object increases with time, its acceleration is positive.

<h2 /><h2>\sf \pink{Question}</h2>

What is a zero acceleration ?

<h2>\sf \blue{Answer}</h2>

Zero acceleration is an acceleration, just with zero magnitude. Motion with constant velocity is just a special case of motion with uniform acceleration.

<h2>\sf \pink{Question}</h2>

What is a negative acceleration ?

<h2>\sf \blue{Answer}</h2>

A negative acceleration means you will subtract from the current value of the velocity, and a positive acceleration means you will add to the current value of the velocity. ... And if the acceleration points in the opposite direction of the velocity, the object will be slowing down.

If the decomposition of a sample of k c l o 3 kclox3 produces 3. 29 g of o 2 ox2 , what was the mass (g) of the original sample?
____ [38]

The mass (g) of the original sample after decomposition is 8.3983 g.

A decomposition reaction can be described as a chemical reaction wherein one reactant breaks down into or extra merchandise.

explanation:

Reaction          2KClO₃ ⇒ 2KCl + 3O₂

moles               2               2            3

molar mass    122.55        74.55    32

Given, Mass of O₂ = 3.29g ⇒ moles of O₂

                                            =  (3.29/32) = 0.1028

3 moles of O₂  produced by 2 moles of KClO₃

Therefore, 0.1028 moles of O₂  produced by (2*0.1028/3) = 0.06853 moles of Kclo₃

Mass of KClo₃ in original sample is = moles * molar mass

                                                        = 0.06853 * 122.55

                                                       = 8.3983 g

A decomposition response occurs whilst one reactant breaks down into or extra merchandise. this may be represented through the general equation: XY → X+ Y. Examples of decomposition reactions consist of the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.
