Answer:

The kinetic energy and the orientation of the molecules.

Explanation:

As per the collision theory, in order for the reactants yield the products, the molecules or particles must collide with a kinetic energy greater than or equal to the activation energy, and they must collide in the right orientation for the old bonds can be broken and the new ones formed.

The particles of reactants that collide either with less kinetic energy than the needed or in a different orientation will not drive to formation of new products but will "bounce" without producing any chemical change.

This theory is in agreement with the observations that increasing the concentration of reactants increases the rate of reaction, because more collisions will be occur, such as increasing the temperature also increases the rate of reaction, because the collisions will be more energetic.

. A sample of crude oil has a density of 0.87 g/mL. What volume (in liters) does a 3.6 kg sample of this oil occupy

gayaneshka [121]

Answer:

The volume is 4.13793 L

Explanation:

Density is a quantity that expresses the relationship between the mass and the volume of a body, so it is defined as the quotient between the mass and the volume of a body:

$density=\frac{mass}{volume}$

Density is a characteristic property of every body or substance.

The most commonly used units of density are $\frac{kg}{m^{3} }$ or $\frac{g}{cm^{3} }$ for solids, and $\frac{kg}{L}$ or $\frac{g}{mL}$ for liquids and gases.

In this case, you know:

density= 0.87 $\frac{g}{mL}$
mass= 3.6 kg= 3,600 g (being 1 kg=1,000 g)
volume= ?

Replacing:

$0.87\frac{g}{mL} =\frac{3,600 g}{volume}$

Solving:

$volume =\frac{3,600 g}{0.87\frac{g}{mL}}$

volume= 4,137.93 mL

Being 1,000 mL=1 L, then volume= 4,137.93 mL= 4.13793 L

The volume is 4.13793 L

Which principle goes against Bohr's theory and why??

Basile [38]

Answer:

As the Bohr's fixed orbit gives precise information about the radial position and momentum of the orbit, it is against the Heisenberg uncertainty principle. Thus it is inferred that the Heisenberg uncertainty principle goes and the concept Bohr's fixed Orbit are opposite to each other.
