The conversions are:
Electrical to electromagnetic and mechanical (when we turn on the microwave).
Electromagnetic to thermal (as the microwave heats up the cup of water).
What energy conversions occur?
We will describe the process in which you already have a cup of water inside the microwave.
First, you turn on the microwave. Here you are giving the microwave electrical energy so it can work.
The microwave rotates the cup of water, so there is a transformation of electric energy into mechanical energy.
The microwave also creates electromagnetic radiation which affects the cup, so there is a change from electric energy to electromagnetic energy.
This electromagnetic energy interacts with the water by increasing the temperature, so finally we have a change from electromagnetic energy to thermal energy.

Calculate the number of moles contained in 550. ml of carbon dioxide at stp.
Considering the definition of STP conditions, 0.02455 moles are contained in 550 mL of carbon dioxide at STP.
Definition of STP conditionThe STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.
Amount of moles contained in 550 mLIn this case, you can apply the following rule of three: if by definition of STP conditions 22.4 liters are occupied by 1 mole of helium, 0.550 L (0.550 L= 550 mL, being 1 L= 1000 mL) are occupied by how many moles?
[tex]amount of moles=\frac{0.550 Lx 1 mole}{22.4 L}[/tex]
amount of moles= 0.02455 moles
Finally, 0.02455 moles are contained in 550 mL of carbon dioxide at STP.

A 20.0-ml sample of a 0.200 mhbr solution is titrated with a 0.200 mnaoh solution. calculate the ph of the solution after the following volumes of base have been added.
The calculated pH of the solutions are given below:
The pH of the solution after 14.0 ml of base is added to it is calculated as 1.45. The pH of the solution after 19.8 ml of base is added to it is calculated as 3.0The pH of the solution after 20.0 ml of base is added to it is calculated as 7. What is pH?This is the level of acidity or alkalinity of an aqueous solution. The pH of a substances tells if its an acid, base or neutral.
HBr and NaOH while in water would dissociate and they would become H+ and OH- respectively.
Mol of HBr = Mol * Vol
= 0.200 * 20mL
= 4 mmol
A. Moles of NaOH added
= 0.2 X 14
= 2.8 mmol
Moles of H+ that did not react
= 4 - 2.8
= 1.2 mmol
1.2/1000 = 0.0012 moles
Total volume = 20 + 14
= 34 mL to litres
= 0.034 L
Molarity of H+ = 0.0012 / 0.034L
= 0.035 M
-log[0.035] = 1.45
The pH of the solution is 1.45
B. NaOH added = 19.8 * 0.2 =
3.96 mmoles
The unreacted solution
= 4.0 - 3.96
= 0.04 mmol
0.04/1000 = 0.00004 moles
Total volume = 20 + 19.8
= 39.8mL
Converted to litres = 0.0398L
Molarity = 0.00004 / 0.0398L
= 0.001
-log(0.001) = 3.0
The ph Is therefore 3.0
C. Moles of NaOH added = 0.2*20mL = 4mmol
All the H+ are going to be consumed here. This would result into a neutral solution pH = 7

Explanation:
The molecule cyanazine, once used as an herbicide, has now been phased out by the epa because of its significant human toxicity. add lone pairs, as needed, to the structure of cyanazine.
For the molecule cyanazine, the hybridization of atom 1 would be a sp³ hybridization when lone pairs are added.
What is hybridization?Hybridization is a phenomenon in chemistry which involves the linear combination of two (2) or more atomic orbitals of a molecule or chemical compound, in order to form the same number of hybrid orbitals, with each of the orbital having equal amount of energy and the same shape.
Since nitrogen (N) in cyanazine is bonded with three (3) single bonds, two carbon (C) and one hydrogen (H) bond, we can deduce that the hybridization of atom 1 would have a sp³ hybridization.

How many molecules of no2 can be formed using 2 molecules of no
The number of molecules of NO₂ that can be obtained when 2 molecules of NO react is 2 molecules
Balanced equationWe'll begin by writing the balanced equation for the reaction. This is given below:
NO + O₂ —> NO₂
There are 3 atoms of O on the left side and 2 atoms on the right side. It can be balanced by writing 2 before NO and NO₂ as shown below
2NO + O₂ —> 2NO₂
Now, the equation is balanced
From the balanced equation above,
We can see that 2 molecules of NO will react to produce 2 molecules of NO₂.
Thus, we can conclude that 2 molecules of NO₂ will be obtained from the reaction.
