Answer:

Nuclear Energy is the answer

Answer:

Following are the solution to this question:

Explanation:

Mendeleev has been the chemist that designed a periodic table for component identification based on the increasing number of elements. Thus, the is traditionally called a table parent and this periodic table had some drawbacks.

Consequently, Mosley rebuilt Mendeleev's periodic table to once again overcome this disadvantage. Which atoms were arranged as per the increasing order of atomic number instead of mass number. The traditional table, therefore, comprises seven horizontal lines regarded as cycles. But 18 control limits were named group lines.

The whole Periodical Tables is classified as a,p,d, and f block

S block, groups have 1 and 2.

P block, group has 13-18  

D block, group has 3 to 12

F block, – Two lines far below the periodic table.

Answer:

Mass = 16.4 g

Explanation:

Given data:

Mass of K = 8.50 g

Mass of KCl produced = ?

Solution:

Chemical equation:

2K + Cl₂     →    2KCl

Number of moles of K:

Number of moles = mass/ molar mass

Number of moles = 8.50 g/ 39 g/mol

Number of moles = 0.22 mol

Now we will compare the moles of potassium and potassium chloride.

                  K         :        KCl

                  2         :          2

                0.22      :        0.22

Mass  of KCl:

Mass = number of moles × molar mass

Mass = 0.22 mol × 74.55 g/mol

Mass = 16.4 g

Answer: It is B) Elements from the bottom left and the top right of the periodic table.

Explanation: Elements from bottom left and top right will create the most polar bonds. electronegativity generally increased from bottom left to top right of the periodic table

Answer:

Energy of photon is 34.45 ×10⁻¹⁹ J.

Explanation:

Given data:

Frequency of photon = 5.2×10¹⁵ s⁻¹

Plancks constant = 6.626×10⁻³⁴ Js

Energy of photon = ?

Solution:

Formula:

E = h.f

by putting values,

E =  6.626×10⁻³⁴ Js × 5.2×10¹⁵ s⁻¹

E = 34.45 ×10⁻¹⁹ J

Thus, energy of photon is 34.45 ×10⁻¹⁹ J.

Explanation:

Answer:

Number of Protons

Explanation:

The number of Protons is always equivalent to the amount of electrons that are on the outside of the atom

Answer:

Explanation:

Atoms are held together by covalent bonds when they share electrons between themselves.

Covalent bonds are bonds that are formed between non-metals usually with a low electronegative difference between them. In this bond type, two non-metals donate electrons which are shared between the combining atoms and this makes them both like the corresponding noble gases. The shared electrons is what forms the covalent bonds.

An example of covalent bond is HCl, H₂S, SO₂, CO₂, O₂ etc

Mass of NaCl L 13.75 g

Given

The solution of 5.5% by mass

mass of commercial bleach solution : 250 g

Required

mass of NaCl

Solution

Percent mass (% w/w) = percent mass of solute in 100 g mass of solution

Solution = solute + solvent

Solute = NaCl

Solution = Commercial bleach

Can be formulated :

[tex]\tt \%mass(w/w)=\dfrac{mass~solute}{mass~solution}\times 100\%[/tex]

Input given values in formula :

[tex]\tt \%mass=\dfrac{mass~NaCl}{mass~commercial~bleach}\times 100\%\\\\5.5\%=\dfrac{mass~NaCl}{250}\times 100\%\\\\mass~NaCl=\boxed{\bold{13.75~g}}[/tex]

Answer:

The epicenter is the same distance from both recording stations

Explanation:

ΔT is the time between anomaly occurrence and the origin time of the earthquake.

Now, we are told both stations had the same value for ΔT.

This means that their points on the earth's surface which vertically above the focus of the earthquake is the same and thus we can conclude that the epicenter is the same distance from both stations.

Explanation:

In the extreme winters , the water inside pipes freeze, on freezing it's(water molecule)  density decreases and volume increases and therefore, the ice then expands and pushes the water towards the faucet, causing high pressure buildup in the pipe and after a limit the pipe burst. This is what happened to the family in Ottawa, where winters are chilly.

Answer:

Since their family turned off the heat, it should be cold, the pipes must be freezing, and there is water in the pipes which means the water in the pipes is freezing causing it to burst.

Explanation:

I am 16 years old.

Answer:

The glucose concentration is measured in mM, the abbreviation for "milliMolar". The molar (M) concentration of a solution is a measure of how much solute (the component of a solution present in lesser amount, often a solid) there is in a given volume of solution. After swirling the flask to dissolve the solid, water is added carefully until the bottom of the meniscus coincides with the calibration mark on the neck of the flash.

Answer:

sugar molecules......

Answer:

B) 3.34

Explanation:

V1/T1 = V2/T2

So V2= (T2xV1)/T1

Side note Temp for using gas law is always kelvin (Celsius +273.15)

Volume is always in Liters

So V2 = (372.6Kx2.65L)/295.55L

Which results in 3.34L

Answer:

Fossil fuels and biomass combustion.

Explanation:

The mass combustion of fossil fuels and biomass results in the vast release of Black Carbon (BC) and Brown Carbon (BrC) and dust. These Black Carbon, light absorbing organic Brown Carbon and dust cause the discolouring and yellowing of the surface of Taj Mahal building.

Answer:

Acid rain causes discoloring Taj Mahal

Answer:

Mass = 312 g

Explanation:

Given data:

Number of molecules of H₂ = 9.4 × 10²⁵

Mass in gram = ?

Solution:

First of all we will calculate the number of moles of H₂.

1 mole of H₂ contain 6.022× 10²³ molecules

9.4 × 10²⁵ molecules  × 1 mol / 6.022× 10²³ molecules

1.56× 10² mol

156 moles of H₂:

Mass in gram:

Mass = number of mole × molar mass

Mass = 156 mol × 2 g/mol

Mass = 312 g

Answer:

(d) Iron (II) sulfide (FeS) is precipitated most likely and is an renowned ore of iron. (e) Potassium sulfate (K₂SO₄) is like to remain mostly in its ionic form and has less tend to precipitate. Thus FeS will be more likely to be precipitated.

Explanation:

Answer:

Going through a phase. Adding or removing energy from matter causes a physical change as matter moves from one state to another. For example, adding thermal energy (heat) to liquid water causes it to become steam or vapor (a gas). Physical changes can also be caused by motion and pressure.
