Answer:Plastic wrap is transparent and so nearly all light passes through easily ,

Wax Paper is translucent and so light is blurred or scattered .

Explanation:

What is Reflection ?

Reflection of light occurs when light hits a smooth surface that does not absorb any of the light but instead bounces it back off the surface.

A mirror is flat, smooth, and polished. When light hits a mirror it is not absorbed but is reflected off at a very predictable angle.

The angle that the light hits the mirror is called the angle of incidence.

The angle of light that bounces off the mirror is called the angle of reflection.

The Law of Reflection states that the angle of incidence is equal to the angle of reflection.

Answer:

Step 1 of 3

To determine pressures in each of the different units, you need the below relations:

(a) To convert pressure in atmospheres to mm Hg, use the relation given by,

We have, initial pressure charged to the system is 4.8 atm. So, the pressure in mm Hg is  So, the pressure in mm Hg is.Freon-12 is used as a refrigerant in central home air conditioners. The rate of effusion of Freon-12 to Freon-11 (molar mass = 137.4 g/mol) is 1.07:1. The formula of Freon-12 is one of the following:

\mathrm { CF } _ { 4 } , \mathrm { CF } _ { 3 } \mathrm { Cl }, \mathrm { CF } _ { 2 } \mathrm { Cl } _ { 2 } , \mathrm { CFCl } _ { 3 } , \text { or } \mathrm { CCl } _ { 4 }. CF  4 ,CF  3Cl,CF  2 Cl  2 ,CFCl  3 , or CCl  4

​

Explanation:

The system is initially charged to a pressure of 4.8 atm.  4.8 atm in mm Hg is 3648 mm Hg, 4.8 atm in torr is 3648 Torr, 4.8 atm in Pa is  486360Pa and 4.8 atm in Psi is 70.56 psi.

The force applied to a unit area of a surface is described by pressure, a fundamental concept in physics and chemistry. It describes how much force is distributed over a certain area.

A. mm Hg (millimeters of mercury):

1 atm = 760 mm Hg

So, 4.8 atm = 4.8 ×760 mm Hg

                   ≈ 3648 mm Hg

B. Torr:

1 atm = 760 Torr

So, 4.8 atm = 4.8 ×760 Torr

                   = 3648 Torr

C. Pa (Pascals):

1 atm = 101325 Pa

So, 4.8 atm = 4.8 × 101325 Pa

                   ≈ 486360Pa

D. psi (pounds per square inch):

Given: 1 atm = 14.7 psi

So, 4.8 atm = 4.8 ×14.7 psi

                  ≈ 70.56 psi

Answer:

NH4OH

Explanation:

NH4OH is a weak base because it partially dissociates into NH + and OH− ions in aqueous solutions and the amount of OH− ions produced is low.

The mass of titanium metal formed is 148g.

The equation of the reaction is;

TiBr4(s) + 2H2(g) ------>Ti(s) + 4HBr(g)

The number of moles of hydrogen gas = 12.5 g/2.00 g/mol = 6.25 moles of hydrogen gas

If 2 moles of hydrogen gas yields 1 mole of titanium metal

6.25 moles of hydrogen gas yields 6.25 moles × 1 mole/2 moles = 3.1 moles of titanium metal

Mass of titanium metal = 3.1 moles of titanium metal × 47.8 g/mol = 148g

Explanation:

The value of heat energy in a bomb calorimeter with  a glucose sample of mass 4.40 g if changes temperature from 15 to 18 degree celsius is 16369.54 kJ.

Calorimeter is a thermal device used to determine the heat evolved or absorbed from a reaction. From this we can also calculate the enthalpy change.

If the enthalpy is negative, then the reaction is endothermic. If enthalpy change is positive, then the reaction is exothermic. The equation for finding the heat energy q from the mass, temperature change and heat capacity of calorimeter is given below:

q = mc ΔT.

It is given that the total mass is 804.40 g and heat capacity of the calorimeter is 550 J/°C g, then the heat energy  q is calculated as follows:

q = 804.40 g × 550 J/°Cg (18.7 °C - 15 °C)

  = 16369540J

  = 16369.54 KJ.

Hence, the value of q for the bomb calorimeter is 16369.54 KJ.

D nuclear fission, the process where the nucleus of an atom is split into two or more smaller nuclei. Nuclear fusion is the reaction of the combination of nuclei.

The hydrolysis of  N,N-diethyl-m-toluamide yields 3-methylbenzoic acid which easily biodegradable.

The insecticide repellent N,N-diethyl-m-toluamide is used to repel rather than kill insects. It functions by interfering with the ability of the insects to detect body heat and skin chemicals. In a nutshell, it confuses the receptors in the insect.

The hydrolysis of N,N-diethyl-m-toluamide  yields 3-methylbenzoic acid and diethylamine as the products. This is important because the 3-methylbenzoic acid is not an environmental concern since it is readily biodegradable and does not accumulate significantly in living organisms. It has also not been found to be mobile in soil and water. Environmental concerns are always a prime consideration in assessing chemicals for use.
