What makes a light wave different from all mechanical waves?
Answer:
Light is a transverse wave.
Explanation:
Light waves are not considered mechanical waves because they don't involve the motion of matter. Most of the mathematics and properties of mechanical waves apply to light waves. Light waves are different from mechanical waves, however, because they can travel through a vacuum.

Explanation:
If 86.4dm^3 of carbon dioxide gas contains N × 10^23 molecules at room temperature and pressure, find the value of N.
At T 25 ° C (298 K) and P 1 atm are stated by RTP ⇒ Vm = 24.4 liters / mol
86.4 dm³ = 86.4 L = 86.4/24.4 = 3.54 mol
1 mole = 6.02.10²³ molecules
3.54 x 6.02.10²³ = 21.31 x 10²³ molecules
N = 21.31
what volume of N2 is required to convert 5.0L of hydrogen gas to ammonia? assume that all gases are at the same temperature and pressure and that the reaction is complete
Answer:
Approximately [tex]1.7\; {\rm L}[/tex].
Explanation:
Nitrogen [tex]{\rm N_{2}}\, (g)[/tex] reacts with hydrogen [tex]{\rm H_{2}}\, (g)[/tex] at a [tex]1:3[/tex] ratio to produce ammonia [tex]{\rm NH_3}\, (g)[/tex]:
[tex]{\rm N_{2}}\, (g) + 3\; {\rm H_{2}}\, (g) \to 2\; {\rm NH_{3}}\, (g)[/tex].
The ratio between the coefficient of [tex]{\rm N_{2}}\, (g)[/tex] and the coefficient of [tex]{\rm H_{2}}\, (g)[/tex] is:
[tex]\begin{aligned}\frac{n({\rm N_{2}})}{n({\rm H_{2}})} = \frac{1}{3}\end{aligned}[/tex].
Under the ideal gas assumptions, the same ratio would apply to the volume of [tex]{\rm N_{2}}\, (g)[/tex] and [tex]{\rm H_{2}}\, (g)[/tex] in this reaction:
[tex]\begin{aligned}\frac{V({\rm N_{2}})}{V({\rm H_{2}})} = \frac{n({\rm N_{2}})}{n({\rm H_{2}})} = \frac{1}{3}\end{aligned}[/tex].
[tex]\begin{aligned}V({\rm N_{2}})= \frac{1}{3}\, V({\rm H_{2}})\end{aligned}[/tex].
Given that [tex]V({\rm H_{2}}) = 5.0\; {\rm L}[/tex]:
[tex]\begin{aligned}V({\rm N_{2}}) &= \frac{1}{3}\, V({\rm H_{2}}) \\ &= \frac{1}{3}\times 5.0\; {\rm L} \\ &\approx 1.7\; {\rm L}\end{aligned}[/tex].
(Rounded to [tex]2[/tex] significant figures.)

Barium nitrate Ba (NO3)2 is used to produce a green colour in fireworks. It is the product of Barium Hydroxide with HNO3. Propose its balanced chemical equation
The balanced chemical equation for the reaction between barium hydroxide, Ba(OH)₂ and HNO₃ to produce barium nitrate, Ba(NO₃)₂ is
Ba(OH)₂ + 2HNO₃ —> Ba(NO₃)₂ + 2H₂O
What is a chemical equation?Chemical equations are representations of chemical reactions using symbols and formula of the reactants and products.
The reactants are located on the left side while the products are located on the right side.
Reactants —> Products
The balancing of chemical equations follows the law of conservation of matter which states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another.
How to write the balanced equationBa(OH)₂ + HNO₃ —> Ba(NO₃)₂ + H₂O
There are 2 atoms of N on the right side and 1 atom on the left side. It can be balanced by writing 2 before HNO₃ as shown below:
Ba(OH)₂ + 2HNO₃ —> Ba(NO₃)₂ + H₂O
There are 4 atoms of H on the left side and 2 atoms on the right side. It can be balanced by writing 2 before H₂O as shown below
Ba(OH)₂ + 2HNO₃ —> Ba(NO₃)₂ + 2H₂O
Now, the equation is balanced

If 25.0 g NO are produced, how many grams of nitrogen gas are used?
A: 5.84 g
B: 11.7 g
C: 23.3 g
D: 33.6 g
Based on the assumption that the reaction involves N and O to produce NO, if 25.0 g of NO are produced, the amount of N gas used would be 11.66 grams
Stoichiometric calculationFrom the equation of the reaction:
N + O ---------> NO
Mole ratio of N to NO is 1:1
Mole of 25.0 g of NO = 25/30.01 = 0.833 moles
Equivalent mole of N = 0.833 moles
Mass of 0.833 moles N = 0.833 x 14 = 11.66 grams

What is the temperature when the volume is 4L? The original temperature is 200K and the
original volume is 5L.
Answer:
160
Explanation:
p*v/t = constant
or
p1*v1/t1 = p2*v2/t2
pressure is not stated in question so we get rid of it on both sides
v1/t1 = v2/t2
we are finding temperature so we flip the entire equation
t1/v1 = t2/v2
200/5 = t2/4
4(200/5) = t2
=160
Answer:
Yes it is 160K as the first person said

Solar energy and wind energy can both easily be integrated into existing power grid systems.
What is Levelized Cost of Energy?The Levelized Cost of Energy is a measure of the average net present cost of electricity generation for a generating plant over its lifetime.
The Levelized Cost of Energy of the solar energy product is calculated as follows:
Total cost over 25 years = 995,000, + $175,000 × 25 = $5,370,000
Total energy production over 25 years = 89,500,000 kWh
Levelized Cost of Energy = $5,370,000/89,500,000 kWh
Levelized Cost of Energy = $0.60 per kWh

Using the notation just described, represent a cell based on the following reaction:
ClO3−(aq)+3Cu(s)+6H+(aq)→Cl−(aq)+3Cu2+(aq)+3H2O(l)
Pt is used as an inert electrode in contact with the ClO3− and Cl− .
Drag the appropriate labels to their respective targets. For neutral species, leave the pink target blank.
The cell notation of the redox reaction between Cu and ClO₃⁻ is:
Cu/Cu²⁺//ClO₃⁻//Cl⁻/PtWhat is a voltaic cell?A voltaic cell or electrochemical cell is a device which produces electricity from chemical reactions occuring within the cell.
The reactions occuring in a voltaic cell are redox reactions.
Oxidation occurs at the anode while reduction occurs at the cathode.
In the given reaction between Cu and ClO₃⁻ as shown below:
ClO₃⁻ (aq) + 3 Cu (s) + 6H⁺ (aq) → Cl⁻ (aq) + 3 Cu²⁺ (aq) + 3 H₂O (l)Cu is oxidized as follows: 3 Cu (s) → 3 Cu²⁺
ClO₃⁻ is reduced as follows: ClO₃⁻ (aq) → Cl⁻ (aq)
The voltaic cell notation is as follows where Pt is used as an inert electrode in contact with the ClO₃⁻ and Cl⁻:
Cu/Cu²⁺//ClO₃⁻//Cl⁻/PtTherefore, the cell notation of the redox reaction between Cu and ClO₃⁻ shows that Cu is oxidized while ClO₃⁻ is reduced.

How are elements organized on the modern periodic table?.
Answer:
They are organized from least to greatest by their atomic number.
Explanation:
Hope that helps!
Answer:
Explanation:
Elements are listed in numerical order by atomic number. The atomic number is the number of protons in an atom of that element. So element number 1 (hydrogen) is the first element. Every atom of hydrogen has 1 proton. Until a new element is discovered, the last element on the table is element number 118. Every atom of element 118 has 118 protons. This is the biggest difference between today's periodic table and Mendeleev's periodic table. The original table organized the elements by increasing atomic weight.
Each horizontal row on the periodic table is called a period. There are seven periods on the periodic table. Elements in the same period all have the same electron ground state energy level. As you move from left to right across a period, elements transition from displaying metal characteristics toward nonmetallic properties.
Each vertical column on the periodic table is called a group. Elements belonging to one of the 18 groups will share similar properties. Atoms of each element within a group have the same number of electrons in their outermost electron shell. For example, elements of the halogen group all have a valence of -1 and are highly reactive.
There are two rows of elements found below the main body of the periodic table. They are placed there because there wasn't room to put them where they should go. These rows of elements, the lanthanides and actinides, are special transition metals. The top row goes with period 6, while the bottom row goes with period 7.
Each element has its tile or cell in the periodic table. The exact information given for the element varies, but there is always the atomic number, the symbol for the element, and the atomic weight. The element symbol is a shorthand notation that is either one capital letter or a capital letter and a lowercase letter. The exception is the elements at the very end of the periodic table, which have placeholder names (until they are officially discovered and named) and three-letter symbols.
The two main types of elements are metals and nonmetals. There are also elements with properties intermediate between metals and nonmetals. These elements are called metalloids or semimetals. Examples of groups of elements that are metals include alkali metals, alkaline earths, basic metals, and transition metals. Examples of groups of elements that are nonmetals are the nonmetals (of course), the halogens, and the noble gases.
