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

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.

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

Explanation:

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.

Answer:

Your answer is ATOM

Explanation:

Atoms consist of a nucleus made of protons and neutrons orbited by electrons. Atoms are the basic units of matter and the defining structure of elements.

Based on the data provided,  the rate of the given reactions are:

a. reaction rate =  0.0132 M/sec

b. rate of change of [H⁺] = 8.8 * 10⁻³ M/sec

Reaction rate = change in concentration of reactant or product/ time taken

Change in concentration of I⁻ = 1.000 M - 0.868 M= 0.132

time taken = 10 s

reaction rate = 0.132/10

Rate of reaction = 0.0132 M/sec

From the equation of the reaction 3 moles of I⁻ are used up for every 2 moles of H⁺

Hence, the rate of change of [H⁺] = 0.0132 M/sec * 2/3

rate of change of [H⁺] = 8.8 * 10⁻³ M/sec

Therefore, the rate of the given reactions are:

a. reaction rate =  0.0132 M/sec

b. rate of change of [H⁺] = 8.8 * 10⁻³ M/sec

In the research scenario, Dora's father uses engine oil to shield engine pumps from friction and injury. Friction is a force among contact objects that slip or threaten to slide over each other.

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

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.

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

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:

Lithium = 8%

Bromine = 92%

Explanation:

To calculate percent composition, you must:

- Calculate the molar mass.

- Divide the subtotal for each element's mass by the molar mass.

- Convert to a percentage

With that being said, given LiBr (Lithium Bromide), calculate the molar mass:

Lithium has an atomic weight of 7, and there is one Lithium atoms in LiBr. Bromine has an atomic weight of 80, and there is one Bromine atom in LiBr:

[tex]1(7)\\1(80)[/tex]

Add the two products:

[tex]80+7[/tex]

[tex]=87[/tex]

The molar mass of LiBr is about 87 grams.

With that information, divide the subtotal of Lithium by the molar mass, and then multiply by 100 to convert to a percentage:

[tex]\frac{7}{87}[/tex] × [tex]100=[/tex]

8.0459%

(Round to nearest percentage):

8%

Therefore, the percent composition of Lithium in the compound Lithium Bromide is about 8%.

Now, divide the subtotal of Bromine by the molar mass, and then multiply by 100 to convert to a percentage:

[tex]\frac{80}{87}[/tex] × [tex]100=[/tex]

91.9540

(Round):

92%

Therefore, the percent composition of Bromine in the compound Lithium Bromide is about 92%.

atomic mass

In 1869, Mendeleev published the first periodic table of the elements. In his periodic table, Mendeleev arranged elements in rows by increasing atomic mass. Within a row, elements with lower atomic masses were on the left. Mendeleev started a new row every time the chemical properties of the elements repeated.
