the question is~ Where does the heat come from for geothermal energy?​

You come across an article in a scientific journal from 50 different laboratories around the globe that measured the boiling point of water and discovered that it is 100°C everywhere.

Water turns into gas around 212°F (100°C), which is the temperature at which it begins to boil (water vapor). Pressure affects the melting/freezing and boiling points. Water's boiling point changes when air pressure changes. The boiling point decreases with increasing altitude or decreasing pressure.

Water has a freezing point of 32 degrees Fahrenheit and a boiling point of 212 degrees Fahrenheit on the Fahrenheit scale.

Explanation:

Answer:

a. Oxygen

b. 20.39g of Al₂O₃

c. 87%

Explanation:

In order to produce 2moles of Al₂O₃, we need to make react 4 moles of Al, to 3 moles of O₂.

We determine the limiting reactant with the moles of each:

12.98g / 26.98g/mol = 0.481 moles of Al

9.6g / 32g/mol = 0.300 moles of oxygen

4 moles of Al react to 3 moles of O₂

Then, 0.481 mol may react to (0.481 . 3)/4 = 0.361 moles

We only have 0.300 moles of O₂ and we need 0.361. Oxygen is the limiting reactant.

So 3 moles of O₂ can produce 2 moles of Al₂O₃

Our 0.300 moles may produce (0.300 . 2) / 3 = 0.200 mol

Our theoretical yield is: 0.2 mol . 101.96g/ mol = 20.39 g

To determine the percent yield we calculate:

(Produced yield/ Thoeretical yield) . 100 → (17.74 /20.39) . 100 = 87%

Answer: The partial pressure in atm of ammonium telluride is 1.48 atm

Explanation:

According to Raoult's law, the partail pressure of a component at a given temperature is equal to the mole fraction of that component multiplied by the total pressure

[tex]p_A=x\times p_{total}[/tex]  

where, x = mole fraction

[tex]p_A[/tex] = partial pressure of A

[tex]p_{total}[/tex] = total pressure  

[tex]x_{\text {ammonium telluride}}=\frac{\text {moles of ammonium telluride}}{\text {total moles}}[/tex],  

[tex]x_{\text {ammonium telluride}}=\frac{\frac{2.62g}{164g/mol}}{\frac{2.62g}{164g/mol}+\frac{3.83g}{333g/mol}+\frac{1.82g}{673g/mol}}=0.53[/tex]

[tex]p_{\text {ammonium telluride}}=0.53\times 2.795atm=1.481atm[/tex]

Thus the partial pressure in atm of ammonium telluride is 1.48 atm

Per my research, it was said that each of the atoms of the carbon has over 6 protons, six neutrons, and 6 protons. Each atom of nitrogen has 7 protons, 7 electrons, and 7 neutrons. The atomic mass of carbon and nitrogen is 12 and 14 respectively. As the number of electrons in the atoms of the two elements is different they have different chemical properties.

As you may know, I did my research and this is what it gave me. I would suppose it is correct since it explains that the carob has over 6 protons and so on. Correct me if I am incorrect and I hope this helped. Have a good one!

Explanation:

Answer:

It is neither a synthesis reaction nor a decomposition reaction because two reactants form two products.

Explanation:

This reaction would be considered a single replacement reaction.

The chemical reaction involves the products and the reactants. The image is neither synthesis nor decomposition as the two products are formed from two reactants. Thus, option A is correct.

A chemical reaction includes the chemical interaction between the reactants to yield the products. In a synthesis reaction, two reactants interact to produce a different molecule or compound.

In a decomposition reaction, a reactant undergoes splitting to produce products and energy. But in the image two reactants produces two products that neither of the reaction shows.

This type of reaction is seen as the single replacement reaction where the more reactive element displaces the less reactive from the compound to form the new molecule.

Therefore, option a. Maya's picture represents a single replacement reaction but not a synthesis or decomposition reaction.

The change that would cause entropy to decrease is CO2 gas changing to solid:

Entropy refers to the degree of randomness of a substance.

The higher the degree of randomness the higher the entropy value of that substance.

Entropy increases with increase in temperature as particles of substances gain more kinetic energy.

However, lowering temperature decreases entropy values.

The change from gas to liquid or solid involves lowering of temperature.

Therefore, the change that would cause entropy to decrease is CO2 gas changing to solid.

Número de moles de HCl que reaccionan = 7.5g / 36.5 g / mol = 0.21 moles

Dado que;

4 moles de HCl producen 1 mol de MnCl2

0,21 moles de HCl producen 0,21 * 1/4 = 0,0525 moles de MnCl2.

Masa de MnCl2 = 125,844 g / mol * 0,0525 moles = 6.6 g

Answer:

a. The limiting reactant is Ca(OH)₂

b. The theoretical yield of CaCl₂ is approximately 621.488 grams

c. The percentage yield of CaCl₂ is approximately 47.06%

Explanation:

a. The given chemical reaction is presented as follows;

Ca(OH)₂ + 2HCl → CaCl₂ + 2H₂O

Therefore;

One mole of Ca(OH)₂ reacts with two moles of HCl to produce one mole of CaCl₂ and two moles of water H₂O

The mass of HCl in an experiment, m₁ = 229.70 g

The mass of Ca(OH)₂ in an experiment, m₂ = 207.48 g

The molar mass of HCl, MM₁ = 36.458 g/mol

The molar mass of Ca(OH)₂, MM₂ =74.093 g/mol

The number of moles of HCl, present, n₁ = m₁/MM₁

∴ n₁ = m₁/MM₁ = 229.70 g/(36.458 g/mol) ≈ 6.3 moles

The number of moles of Ca(OH)₂, present, n₂ = m₂/MM₂

∴ n₂ = m₂/MM₂ = 207.48 g/(74.093 g/mol) ≈ 2.8 moles

The number of moles of Ca(OH)₂, present, n₂ = 2.8 moles

According the chemical reaction equation the number of moles of HCl the 2.8 moles of Ca(OH)₂ will react with, = 2.8 × 2 moles = 5.6 moles of HCl

Therefore, there is an excess HCl in the reaction and Ca(OH)₂ is the limiting reactant

b. According the chemical reaction equation the number of moles of CaCl₂ produced in he reaction by the 2.8 moles of Ca(OH)₂ = 2.8 × 2 moles = 5.6 moles of CaCl₂

The molar mass of CaCl₂ = 110.98 g/mol

The mass of the 5.6 moles of CaCl₂ = 5.6 moles × 110.98 g/mol ≈ 621.488 grams

The theoretical yield of CaCl₂ ≈ 621.488 grams

c. Given that the actual mass of CaCl₂ produced = 292.5 grams, we have;

The percentage yield of CaCl₂ = The actual yield/(The theoretical yield) × 100

∴ The percentage yield of CaCl₂ = (292.5 g)/(621.488 g) × 100 ≈ 47.0644646397%

The percentage yield of CaCl₂ ≈ 47.06%.
