A prism refracts white light into rainbow colors because
gogolik [260]

Because each color is refracted differently, each bends at a different angle, resulting in a fanning out and separation of white light into the colors of the spectrum. Water droplets in the air can act in a manner similar to that of a prism, separating the colors of sunlight to produce a spectrum known as a rainbow.

A force of 5000 newtons is applied to a 1200 kg car at rest. What is its acceleration?
insens350 [35]
The formula for acceleration if rearranged based on the force equation is- force over mass. So 5000/1200=4.16

Your answer is 4 m/s squared.

A titanium cube contains 2.86×1023 atoms. what is the edge length l of the cube? the density of titanium is 4.50 g/cm3 . (the vo
IRISSAK [1]
When mass  Ti = density * volume 

and when moles Ti = mass Ti/molar mass Ti

                                 

∴ Volume = 2.86 x 10^23 atom * ( 1 mol Ti / 6.022 x 10^23) * (47.867 g Ti / 1 mol Ti) *(1Cm3 / 4.5 g Ti )

                = 5.05 Cm^3

when we assume that the sample of Ti is a cube:

and we assume the length = X

∴ V = X^3

∴X^3 = 5.05 

∴X = ∛5.05

     = 1.7 Cm

How many moles of naphthalene are required to react stoichiometrically with 1.24 moles of 2-bromo-2-methylpropane to produce 1.2
slava [35]

1.24 moles of naphthalene are required to react stoichiometrically with 1.24 moles of 2-Bromo-2-methylpropane to produce 1.24 moles of t-butyl naphthalene.

<h3>Define Naphthalene.</h3>

An organic substance having the formula C 10H 8 is naphthalene. It is the most basic polycyclic aromatic hydrocarbon, and it has a distinctive odor that may be detected at concentrations as low as 0.08 ppm by mass. It is a white crystalline solid. Naphthalene is an aromatic hydrocarbon with a fused pair of benzene rings as its main structural component. It is most well-known for being the major component of conventional mothballs.

given that,

the moles of 2-Bromo-2-methylpropane are 1.24

1 mole of naphthalene reacts with 1 mole of 2-Bromo-2-methylpropane

x moles of naphthalene react with 1.24 mole of 2-Bromo-2-methylpropane

x = 1 * 1.24/1

= 1.24 moles of naphthalene
