Answer 1

Answer:

A - Cinder cone

B - Shield

C - Composite

Explanation:

Cinder cone volcanoes are formed when the volcano explodes and all the lava soldifies and falls steeply upon the sides of the mountain and forms cinders.

Shield volcanoes form when a centralized vent produces low-viscosity flows over a long period of time

Composite volcanoes are also called stratovolcanoes. They form when different types of eruptions deposit different materials around the sides of a volcano. Alternating eruptions of volcanic ash and lava cause layers to form. Over time these layers build up.

Answers

A- Decomposition .
B- Single replacement.
C-Decomposition.
D-Synthesis.

The following redox reactions are classify as:

(a) 2H₂O₂ ⟶ 2H₂O + O₂: Disproportionation reaction (redox)

(b) Mg + 2AgNO₃ ⟶ Mg(NO₃)₂ + 2Ag: Single displacement reaction (redox)

(c) NH₄NO₂ ⟶ N₂ + 2H₂O: Decomposition reaction (redox)

(d) H₂ + Br₂ ⟶ 2HBr: Combination reaction (redox)

(a) 2H₂O₂ ⟶ 2H₂O + O₂

This reaction involves hydrogen peroxide (H₂O₂) breaking down into water (H₂O) and oxygen gas (O₂). The oxidation state of oxygen in hydrogen peroxide is -1, and in water, it is -2. Oxygen in oxygen gas has an oxidation state of 0. Therefore, oxygen is being reduced from -1 to 0. The oxidation state of hydrogen remains +1 in H₂O₂ and H₂O. Since one element (oxygen) is reduced and the other (hydrogen) remains unchanged, this is a disproportionation reaction (a type of redox reaction).

(b) Mg + 2AgNO₃ ⟶ Mg(NO₃)₂ + 2Ag

In this reaction, magnesium (Mg) reacts with silver nitrate (AgNO₃) to form magnesium nitrate (Mg(NO₃)₂) and silver (Ag). The oxidation state of magnesium changes from 0 to +2 in Mg(NO₃)₂, while the oxidation state of silver changes from +1 in AgNO₃ to 0 in Ag. This is a single displacement reaction (a type of redox reaction) because one element (magnesium) displaces another (silver) in the compound.

(c) NH₄NO₂ ⟶ N₂ + 2H₂O

This reaction involves ammonium nitrite (NH₄NO₂) decomposing into nitrogen gas (N₂) and water (H₂O). The oxidation state of nitrogen in NH₄NO₂ is +3, and in nitrogen gas (N₂), it is 0. The oxidation state of hydrogen changes from +1 in NH₄NO₂ to +1 in H₂O. Since nitrogen is being reduced from +3 to 0, and hydrogen remains unchanged, this is a decomposition redox reaction.

(d) H₂ + Br₂ ⟶ 2HBr

In this reaction, hydrogen gas (H₂) reacts with bromine gas (Br₂) to form hydrogen bromide (HBr). The oxidation state of hydrogen changes from 0 in H₂ to +1 in HBr, while the oxidation state of bromine changes from 0 in Br₂ to -1 in HBr. This is a combination reaction (a type of redox reaction) because two elements (hydrogen and bromine) combine to form a compound (hydrogen bromide), and their oxidation states change during the reaction.

Listed below are the step equations for the reaction in which sulfur dioxide (SO2) and hydrogen disulfide (H2S) react to produce sulfur and water. Write the balanced target equation and use Hess’s law to calculate the ΔH of this reaction.

SO2 (g) → S (s) + O2 (g) ΔH = +300.1 kJ
H2 (g) + S (s) → H2S (g) ΔH = –19.5 kJ
H2 (g) + O2 (g) → H2O (g) ΔH = –290.1 kJ

Answers

Based on Hess law, the enthalpy change, ΔH of the reaction is +48.9 kJ.

What is the equation of the reaction?

The equation of the reaction of sulfur dioxide (SO2) and hydrogen disulfide (H2S) to produce sulfur and water is given below:

[tex]SO_2 + 2H_2S \rightarrow 3S + 2H_2O[/tex]

The ΔH of the reaction is calculated from the summation of the ΔH of the intermediate reactions according to Hess law.

SO2 (g) → S (s) + O2 (g) ΔH1 = +300.1 kJ

H2 (g) + S (s) → H2S (g) ΔH2 = –19.5 kJ

2H2 (g) + O2 (g) → 2H2O (g) ΔH3 = –290.1 kJ

ΔH of the reaction = ΔH1 + 2(-ΔH2) + ΔH3

ΔH of the reaction = 300 + 2 × -(-19.5) + (-290.1)

ΔH of the reaction = +48.9 kJ

Therefore, the ΔH of the reaction is +48.9 kJ.

what would be the mass of 4.640 x 10^21 particles of aluminum

Answers

One mole of aluminum  contains 6.02 × 10²³ Al  particles. One mole of Al weighs 27 g. Hence 4.60 × 10²¹ Al particles or 0.007 moles weighs 0.208 g.  

What is one mole ?

One mole of a substance is its amount containing 6.02 × 10²³  atoms or molecules. This number is called Avogadro number. One mole of every elements contains Avogadro number of atoms.

Similarly one mole of every compound contains 6.02 × 10²³ molecules. The mass of one mole of compound is called its molar mass. Similarly mass of one mole of an element is called its atomic mass.

Al is 13th element in periodic table. Al is a metal.  One mole of Al contains 6.02 × 10²³ Al  atoms . Hence number of moles of   4.60 × 10²¹ Al particles is:

4.60 × 10²¹/ 6.02 × 10²³  = 0.0077 .

atomic mass of Al = 27 g/mol.

Then mass of 0.0077 moles =  0.0077 × 27 = 0.208 g

Therefore, the mass of  4.60 × 10²¹ Al particles is 0.208 g.

From the total pressure of the gaseous mixture, the partial pressure of xenon is 119.5 kPa

What is partial pressure of a gas?

The partial pressure of a gas is the pressure that gas exerts when it is part of a mixture of gases which did not chemically react together.

The sum of the partial pressure of each gas in the mixture gives the total pressure.

In the gaseous mixtures above:

Total pressure = 248.8 kPa

Partial pressure of xenon = Total pressure - (Sum of partial pressure of the other gases)

Partial pressure of xenon = 248.8 - (77.3 + 52.0)

Partial pressure of xenon = 119.5

Therefore, the partial pressure of xenon is 119.5 kPa.

A solution contains an unknown amount of dissolved magnesium. Addition of
0.0877 mol of Na2CO3 causes complete precipitation of all of the magnesium.
What mass of magnesium was dissolved in the solution?

Answers

Taking into account the reaction stoichiometry, 2.13 grams of magnesium was dissolved in the solution.

Reaction stoichiometry

In first place, the balanced reaction is:

Mg²⁺(aq) + Na₂CO₃(aq) → MgCO₃(s) + 2 Na⁺(aq)

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

Mg²⁺: 1 mole Na₂CO₃: 1  moleMgCO₃: 1 moleNa⁺: 2 moles

The molar mass of the compounds is:

Mg²⁺: 24.3 g/moleNa₂CO₃: 106 g/moleMgCO₃: 84.3 g/moleNa⁺: 23 g/mole

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

Mg²⁺: 1 mole ×24.3 g/mole= 24.3 gramsNa₂CO₃: 1 mole ×106 g/mole= 106 gramsMgCO₃: 1 mole ×84.3 g/mole=84.3 gramsNa⁺: 2 moles ×23 g/mole= 46 grams

Mass of magnesium dissolved

The following rule of three can be applied: If by reaction stoichiometry 1 mole of Na₂CO₃ react with 24.3 grams of magnesium, 0.0877 moles of Na₂CO₃ react with how much mass of magnesium?

[tex]mass of magnesium=\frac{0.0877 moles of Na_{2}C O_{3}x24.3 grams of magnesium }{1 mole of Na_{2}C O_{3}}[/tex]

mass of magnesium= 2.13 grams

Finally, 2.13 grams of magnesium was dissolved in the solution.
