Answer:Air in high pressure systems moves in an anticlockwise direction (in the southern hemisphere), while air in low pressure systems moves in a clockwise direction due to the rotation of the Earth. At the surface of the Earth air flows from high pressure systems into low pressure systems.

Explanation:

Warm air rises, creating a low pressure zone; cool air sinks, creating a high pressure zone. Air that moves horizontally between high and low pressure zones makes wind.Smaller pressure systems create localized winds that affect the weather and climate of a local area.

In the Eqn: [3 Fe + 2 O2 → Fe3O4], How many grams of Fe will be needed to react with 6.85 mol O2 ?

Answers

Answer:

575g

Explanation:

Mole ratio Fe : O2 = 3:2

so moles of Fe = 1.5 x 6.85 = 10.275 moles

mass=moles x Ar

Ar Fe= 56

mass = 10.275 x 56=575g

If 186.0 liters of gaseous O_{2} at 1.09 atm and 577.0 ºC are required for the model rocket to climb 1000 feet, how many grams of solid KClO_{3} must be in the rocket engine?

Answers

Answer:

The right answer is "236.53 g".

Explanation:

The given values are:

P = 1.09 atm

V = 186 liters

The reaction will be:

⇒  [tex]KClO_3 (s)\rightarrow 2Kcl(s)+3O_2(g)[/tex]

The moles of O₂ will be:

=  [tex]\frac{PV}{RT}[/tex]

On substituting the values, we get

=  [tex]\frac{1.09\times 186}{0.0821\times 850}[/tex]

=  [tex]\frac{202.47}{69.785}[/tex]

=  [tex]2.90 \ moles[/tex]

Now,

1 mole O₂ is produced from

= [tex]\frac{2}{3} \ mol \ KClO_3[/tex]

then,

2.90 mole O₂ is produced from 2 mol KClO₃

= [tex]\frac{2}{3}\times 2.90[/tex]

= [tex]1.93 \ mol \ KClO_3[/tex]

hence,

The number of grans of solid in the engine will be:

= [tex]1.93\times 122.55[/tex]

= [tex]236.53 \ g[/tex]

Answer:

Fe₂(SO₄)₃ + 6KOH —> 3K₂SO₄ + 2Fe(OH)₃

The coefficients are: 1, 6, 3, 2

Explanation:

__Fe₂(SO₄)₃ + __KOH —> __K₂SO₄ + __Fe(OH)₃

To determine the correct coefficients, we shall balance the equation. This can be obtained as follow:

Fe₂(SO₄)₃ + KOH —> K₂SO₄ + Fe(OH)₃

There are 2 atoms of Fe on the left side and 1 atom on the right side. It can be balance by writing 2 before Fe(OH)₃ as shown below:

Fe₂(SO₄)₃ + KOH —> K₂SO₄ + 2Fe(OH)₃

There are 6 atoms of OH on the right side and 1 atom on the left side. It can be balance by writing 6 before KOH as shown below:

Fe₂(SO₄)₃ + 6KOH —> K₂SO₄ + 2Fe(OH)₃

There are 6 atoms of K on the left side and 2 atoms on the right side. It can be balance by writing 3 before K₂SO₄ as shown below:

Fe₂(SO₄)₃ + 6KOH —> 3K₂SO₄ + 2Fe(OH)₃

Now, the equation is balanced.

Therefore, the coefficients are: 1, 6, 3, 2

The different types of mining are underground, surface, placer, and in-situ. Underground mining uses various materials to excavate resources from beneath the surface of the Earth. Surface mining is a category of mining that in which soil and rock overlying the mineral deposit are removed. Placer mining is the mining of stream bed deposits for minerals. In-situ mining is a mining process used to recover minerals such as copper and uranium through boreholes drilled into a deposit.

Why is there a bond between the ions in potassium chloride

Answers

Answer:

Explanation:

When the two atoms are in contact, potassium transfers its outer electron to chlorine which readily accepts it, resulting in both atoms achieving a state of eight outermost electrons. With this electron transfer, the ionic bond in KCl is formed.

Hope this helped!!!

Potassium has just one valence electron and Chlorine has 7 electrons, Chlorine needs just one atom to complete its octet which is provided by Potassium atom for formation of Potassium Chloride (KCl).

What is Chemical Bonding?

Chemical bonding is the formation of chemical bonds present between two or more atoms or molecules which give rise to new compound. Bond is formed from electrostatic force present between oppositely charged ions like in ionic bonds or by sharing of electrons like in covalent bonds.

There are two types of Chemical Bonding:

1. Ionic Bonding

It is formed between opposite charged particles like Anion (negatively charged) and Cation (Positively charged) by the strong force of attraction.

For example, KCl formed by the ionic bond formation present between Potassium and Chlorine

2.Chemical Bonding

It is formed between two atoms for completing its octet by sharing of electrons.

For example, [tex]H_2[/tex] formed by sharing the electrons to complete its electronic configuration.

Thus, Potassium has just one valence electron and Chlorine has 7 electrons, Chlorine needs just one atom to complete its octet which is provided by Potassium atom for formation of Potassium Chloride (KCl).

7. A certain hydrocarbon, CxHy, is burned (reacts with O2 gas) and produces 1.955 g of CO2 for every
1.000 g of H20. What is the empirical formula of this hydrocarbon?
CxHy + (X + y/4) O2 -> xCO2 + y/2 H2O

Answers

Answer:

The empirical formula of the hydrocarbon is C₂H₅

Explanation:

The formula for the hydrocarbon is [tex]C_xH_y[/tex]

The mass of CO₂ produced per 1,000 g of H₂O = 1,955 g

The equation for the chemical reaction is given as follows;

[tex]C_xH_y[/tex] + (x + y/4) O₂ → XCO₂ + y/2H₂O

From the given chemical equation, counting the number of atoms on both sides of the equation, we have;

The molar mass of CO₂ = 44.01 g/mol

The molar mass of H₂O = 18.01528 g/mol

The number of moles of H₂O in 1,000 g of H₂O = 1,000 g/(18.01528 g/mol) = 55.5084351 moles

The number of moles of CO₂ in 1,955 g of H₂O = 1,955 g/(44.01 g/mol) = 44.4217223 moles

Therefore, given that X moles of CO₂ is produced alongside Y/2 moles of H₂O. we have;

X = 44.4217223, Y/2 = 55.5084351

∴ Y = 2 × 55.5084351 = 111.0168702

The ratio of X to Y = X/Y = 44.4217223/111.0168702 = 0.40013488238

∴ The ratio of X to Y = X/Y ≈ 0.4 = 4/10

X/Y ≈ 4/10

The empirical formula is the representation of molecular formula in the smallest whole number ratio of the elements of the molecules

Therefore, when X = 4, Y = 10, from which we have the smallest ratio as;

When X = 2, Y = 5

The empirical formula of the hydrocarbon is therefore, [tex]C_xH_y[/tex] = C₂H₅

The given chemical equation becomes;

C₂H₅ + (2 + 5/4) O₂ → 2CO₂ + 5/2H₂O

C₂H₅ + 3.25 O₂ → 2CO₂ + 2.5 H₂O

We then have;

4C₂H₅ + 13 O₂ → 8CO₂ + 10 H₂O

The empirical formula of the hydrocarbon, [tex]C_xH_y[/tex] = C₂H₅.
