Answer:

Solar radiation is radiant energy emitted by the sun from a nuclear fusion reaction that creates electromagnetic energy.  About half of the radiation is in the visible short-wave part of the electromagnetic spectrum. The other half is mostly in the near-infrared part, with some in the ultraviolet part of the spectrum.

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.

Answer:g

Explanation:

The mass of glycerol to that would need to be combusted to heat 500.0g of water from 20.0°C to 100.0°C is; 9.32 grams.

We must establish the fact that energy is neither created nor destroyed.

Therefore, the amount of heat absorbed by water is equal to the amount of heat released by the combustion of glycerol.

Total heat absorbed by water, H(water) is;

Q(water) = m C (T2 - T1)

Q(water) = 500 × 4.184 × (100-20)

Q(water) = 167.36 kJ

Consequently, the quantity of heat evolved by the combustion of glycerol is;

Q(glycerol) = 167,360 J = n × ΔH°comb

where, n = no. of moles of glycerol.

167.36 kJ= n × 1654 kJ/mole

n = 167.36/1654

n = 0.1012 moles of glycerol.

Therefore, mass of glycerol combusted, m is;

m = n × Molar mass

m = 0.1012 × 92.09

m = 9.32 g.

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.

Explanation:

Answer:

Q1) 0,1276 M

Molair mass of NaOCl = 74,44 g/mol

You have 9,5 g/L.

You need to calculate with the molar mass, how many moles 9,5 g are:

9,5 g / 74,44 g/mol = 0,1276 molAR

0,1276 mol / 1 L = 0,1276 M

Q2) 27.78  grams

The  mass    ca(Oh)2  needed  to  produce  1.5 l  of  0.25 solution  is  calculated  as follows

find  moles

=moles   = molarity   x  volume

moles is therefore =   1.5  x 0.25  =  0.375  moles

mass  =  moles  x  molar  mass

0.375mol  x  74.09 g/mol  =  27.78  grams

Which of the following is a possible set of quantum numbers for a 3p orbital?

Since you are dealing with a 3p-orbital, your principal and angular momentum quantum numbers will be n=3 and l=1 .

This question involves the simple concept of percent by volume in a solution.

The volume of ethanol present in the bottle is found to be "48.75 ml".

The percent by volume of a solution means the amount of that substance present in the solution, represented as a fraction of the total volume of the solution. Hence, the volume of ethanol present in the bear can be found by using the following formula:

[tex]Percent\ by\ Volume\ of\ Ethanol = \frac{Volume\ of Ehanol}{Total\ Volume\ of\ Beer}(100\ \%)\\\\6.50\ \% = \frac{V}{750\ mL}(100\ \%)\\\\V = \frac{(6.50\ \%)(750\ mL)}{100\ \%}[/tex]

V = 48.75 mL

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.
