Explanation:

Answer:

Explanation:

Answer:

C3H8 + 502+3CO2 + 4H20

Explanation:

In order to get this answer you would have to would balance out the carbons on the products side by multiplying CO2 by 3. The new equation will be 

C3H8 + 02 ----> 3CO2 + H20

Now, that the carbons are balanced, we will look at the hydrogens. We can multiply the number of waters on the product side by 4, to make 4 H20 molecules. This gives both sides of the equation 8 hydrogens. Next we can check our oxygens. There will be 10 oxygens on the products side and 2 on the reactants so to balance these out, we multiply the 02 on the reactants side by 5.

The temperature changes for the water and the metal can be calculated by subtracting their initial temperatures from the final temperature.

AT (water) = √°C - °℃

AT (metal) = √°C - °℃

The above equations give the temperature changes for the water and the metal, respectively. The specific values of the temperatures and the final temperature are not provided, so the actual temperature changes cannot be determined without knowing these values.

In general, the temperature change of a substance is given by the difference between the final and initial temperatures. When a warmer object comes into contact with a cooler one, heat energy is transferred from the warmer object to the cooler one until they reach thermal equilibrium, where their temperatures become equal.

The magnitude of the temperature change depends on factors such as the specific heat capacity of the substances involved and the amount of heat exchanged between them.

To accurately calculate the temperature changes, the specific heat capacities of water and the metal would be needed. Additionally, the masses or quantities of the substances would be necessary to determine the amount of heat exchanged. Without these specific values, it is not possible to provide a precise numerical answer.

Potential energy diagram for a combustion reaction:. CLICK ON IMAGE.

In a typical combustion reaction, the reactants (e.g. a fuel and an oxidizer) are initially at a relatively high potential energy. As the reaction proceeds, the potential energy of the system decreases, and the products (e.g. carbon dioxide and water vapor) are at a lower potential energy than the reactants. The difference in potential energy between the reactants and products corresponds to the heat released during the reaction.

The diagram shows the initial energy level of the reactants, the activation energy required to initiate the reaction, and the final energy level of the products. The activation energy is the minimum amount of energy required for the reaction to occur.

Once the reactants have absorbed enough energy to reach the activation energy threshold, the reaction proceeds spontaneously and releases energy as it progresses to the lower-energy products.

Note that the shape of the potential energy diagram can vary depending on the specific reaction and the reaction conditions. For example, some reactions may have more complex energy profiles with multiple intermediate steps or energy barriers.

Answer:

Your question is complex, because I think you wrote it wrong.

Although in front of this what I can help you is that the carbons are associated between a single, double or triple union.

This depends on whether they are attached to more or less carbons or hydrogens, the carbons have the possibility of joining 4 radicals, both other carbons and hydrogens.

Simple junctions talks about compound organisms called ALKANS.

The double unions, in organic these compounds are called as ALQUENOS.

And as for the tertiary unions, the organic chemistry names them as ALQUINOS.

These compounds that we write, a simple union, the less energy, the less this union, that is why the triple bond is the one that contains the most energy when breaking or destroying it in a reaction.

Explanation:

In a chemical compound the change of these unions if we modified them we would generate changes even in the classifications naming them as well as different compounds and not only that until they change their properties

Answer:

40.3 grams

Explanation:

The balanced chemical equation for the reaction between aluminum (Al) and oxygen (O2) to form aluminum oxide (Al2O3) is:

4Al + 3O2 → 2Al2O3

To determine the amount of aluminum oxide produced, we need to first identify the limiting reactant, which is the reactant that gets completely used up in the reaction.

Using the given masses of Al and O2, we can calculate the number of moles of each:

moles of Al = 10.0 g / 26.98 g/mol = 0.371 mol

moles of O2 = 19.0 g / 32.00 g/mol = 0.594 mol

To determine the limiting reactant, we need to compare the number of moles of each reactant to their stoichiometric coefficients in the balanced equation. The stoichiometric coefficient of Al is 4, while the coefficient of O2 is 3. Therefore, O2 is the limiting reactant because it produces fewer moles of Al2O3 than the amount of Al available.

The moles of Al2O3 produced can be calculated using the mole ratio between O2 and Al2O3 from the balanced equation:

moles of Al2O3 = (0.594 mol O2) x (2 mol Al2O3 / 3 mol O2) = 0.396 mol Al2O3

Finally, we can convert the moles of Al2O3 produced to grams using its molar mass:

mass of Al2O3 = 0.396 mol x 101.96 g/mol = 40.3 g

Therefore, 40.3 grams of aluminum oxide are produced in the reaction.

If you add 25 g of CaCl2 to 1000. mL of water, what concentration of the solution would be 0. 225 grams/liter

Molarity or molar concentration(M) is defined as the  amount of a substance in a given volume of solution.

It is also known as the moles of a solute in a liter of  the solution.

Formula:

Concentration or molarity = number of moles ÷ volume

The number of moles is derived thus;

Number of moles = mass ÷ molar mass

mass of CaCl2 = 25g and molar mass = 110. 98 g/mol

Number of moles = 25 ÷ 110. 98 = 0. 225 mol

Given the volume = 1000 ml = 1 liter

Concentration = 0.225 ÷ 1 = 0. 225 grams/liter

Therefore, If you add 25 g of CaCl2 to 1000. mL of water, the concentration of the solution would be 0. 225 grams/liter

An electron has a negative charge.

The charge of an electron is a fundamental property of the particle, and it is denoted by the symbol "e." The magnitude of the charge of an electron is approximately 1.602 × 10^-19 coulombs (C). This value is considered the elementary charge and is used as a reference for other charges. The charge of an electron plays a significant role in determining the behavior and interactions of atoms and molecules. It is opposite in sign to the charge of a proton, which is positive. The electron's charge allows it to interact with other charged particles, such as protons and ions, through electrostatic forces. Electrons are subatomic particles that orbit the nucleus of an atom in specific energy levels or orbitals. They contribute to the overall stability and chemical properties of atoms and participate in chemical bonding and reactions. The movement of electrons between atoms is what enables the formation of chemical bonds and the sharing or transfer of electrons to create ions. In summary, the charge of an electron is negative, and it plays a fundamental role in the structure and behavior of atoms and molecules.
