Answer: to keep airway clear of mucus and dirt allowing us to breathe easy

Explanation:

Explanation:

The question requires us to identify the two elements present in the molecular formula C10H12O6N5P which present similar chemical and physical properties.

First, we need to identify all elements present in the molecule C10H12O6N5P:

- carbon (C)

- hydrogen (H)

- oxygen (O)

- nitrogen (N)

- phosporus (P)

Next, we can analyze the position of these elements in the periodic table:

Note that H is on the left side of the table, while the other elements (C, N, O and P) are closer together on the right side of the table.

We can see that although there are some elements close on the table, only N and P are part of the same group of the periodic table. Based on this, we can say that N and P should present similar properties because they are part of the same group.

Final answer: N and P should present similar chemical and physical properties (letter D).

Answer:0.0922 Fahrenheit per minute

Explanation: Temperature change in degree Fahrenheit from Celsius is given by multiplying the change in temperature in celsius by 1.8 and adding 32 to it. Now the temperature you added is in Fahrenheit. But the temperature change is for a day. To convert change in temperature per day to per minute divide the obtained answer in Fahrenheit by 24*60.

Thus,

change in temperature in Fahrenheit: (56*1.8)+32= 132.8 degree Fahrenheit

change in temperature per minute: (132.8)/(24*60)= 0.0922 degree Fahrenheit per minute

In order to find the result we will have to do some stoichiometry in this question, first we need to set up the reaction:

3 NO2 + H2O -> 2 HNO3 + NO, the reaction is already properly balanced, but there could be some stoichiometry questions in which you need to balance it first

Now, we have 60 grams of NO2, and we want to know how many grams of NO will be produced, let's check the molar ratio between the two compounds

If we have 3 moles of NO2 we will end up with 1 mol of NO, therefore the molar ratio is 3:1

Answer:Good question!! I’ll try to help you the best I can!

First off, you have to know that acetone has a density of 0.7857 g/cm^2

You also need to know that 1mL = 1cm^3

Once you know that, the rest is pretty easy you’ll see! The next step is a cross product to find out how many cm^2 are in 6.72g :

0.7857 g → 1 cm^3

6.72 g  cm^3

(1 * 6.72) ÷ 0.7857 = x

6.72 ÷ 0.7857 =x

8.55

Which means that for 6.72g of acetone, you have a volume of about 8.55cm^3.

Finally, since we’ve established in the beginning that 1cm³ = 1mL, it’s easy to answer your question!

The volume, in millilitres, of 6.72g of acetone is about : 8.55mL

There you go, I really hope this helped, if there’s anything just let me know!

Explanation:

a) The balanced chemical equation for the reaction is: 2H₂ + O₂ → 2H₂O

b) the number of moles of O₂ required is approximately 1.004 moles.

c)  approximately 45 liters of H₂ and 22.5 liters of O₂ are needed to obtain 45 liters of H₂O.

a) Balancing the chemical equation:

The balanced chemical equation for the reaction is: 2H₂ + O₂ → 2H₂O

b) Calculating the number of moles of the reactants needed to obtain 45 liters of H₂O:

From the balanced equation, we can see that for every 2 moles of H₂O produced, we need 2 moles of H₂ and 1 mole of O₂. Since the stoichiometry is based on moles, we need to convert the given volume of H2O into moles.

To convert volume to moles, we need to use the ideal gas law, PV = nRT. At standard temperature and pressure (STP), the molar volume of an ideal gas is 22.4 liters.

Given that we have 45 liters of H2O, we can calculate the number of moles as follows:

moles of H₂O = (volume of H₂O) / (molar volume at STP)

            = 45 liters / 22.4 liters/mol

            ≈ 2.008 moles of H₂O

Since the stoichiometry of the reaction is 2 moles of H₂O for every 2 moles of H₂, we need an equal number of moles of H₂. Therefore, the number of moles of H₂ required is also approximately 2.008 moles.

For O₂, since the stoichiometry is 1 mole of O₂ for every 2 moles of H₂O, we need half the number of moles of H₂O. Thus, the number of moles of O₂required is approximately 1.004 moles.

c)  the volume of the reactants:

Since the stoichiometry of the balanced equation is 2 moles of H₂for every 1 mole of O₂ and 2 moles of H₂O, we can deduce the volume of the reactants based on their molar volumes at STP.

For 2.008 moles of H₂, the volume can be calculated as follows:

volume of H₂= (moles of H₂) * (molar volume at STP)

            = 2.008 moles * 22.4 liters/mol

            ≈ 45 liters of H₂

For 1.004 moles of O₂, the volume can be calculated similarly:

volume of O₂= (moles of O₂) * (molar volume at STP)

            = 1.004 moles * 22.4 liters/mol

            ≈ 22.5 liters of O₂

Therefore, approximately 45 liters of H₂and 22.5 liters of O₂ are needed to obtain 45 liters of H₂O

The half reaction with a more positive standard reduction potential will proceed spontaneously in a redox reaction

The half reaction with a more positive standard reduction potential will undergo reduction when compared to the half reaction with a more negative standard reduction potential.

Oxidation-reduction reactions, often known as redox reactions, are a set of chemical reactions that involve electron transfer between reactants. In a redox reaction, one reactant is oxidized, losing electrons, while the other reactant is reduced, gaining electrons.

The oxidation half-reaction is the process of losing electrons and increasing the oxidation number, whereas the reduction half-reaction is the process of gaining electrons and decreasing the oxidation number. The total reaction is referred to as the redox reaction.

Half-reaction:Half-reaction refers to the two parts of an oxidation-reduction reaction that happen separately. A half-reaction must always be either an oxidation reaction or a reduction reaction. It also describes the movement of electrons and hydrogen ions in an equation.

The final value for the enthalpy change of the formation of CO2 and 2H2O from their elements (C, H2, and O2) would be -1410 kJ per mole of CO2 and 2 moles of H2O formed.

The enthalpy change (ΔH) for the reaction CO2 + 2H2O → H2CO3 can be calculated by multiplying the stoichiometric coefficients of the balanced equation by the enthalpy values of the corresponding compounds involved in the reaction.

In the given reaction, the enthalpy change is -1410 kJ. However, it's important to note that this enthalpy change corresponds to a specific reaction and may not directly apply to the formation of CO2 and 2H2O from another reaction or process.

If we assume that the reaction is the formation of one mole of CO2 and two moles of H2O, we can say that the enthalpy change for this specific formation reaction is -1410 kJ.

Therefore, the final value for the enthalpy change of the formation of CO2 and 2H2O from their elements (C, H2, and O2) would be -1410 kJ per mole of CO2 and 2 moles of H2O formed.

It's worth mentioning that the enthalpy change can vary depending on the specific conditions (temperature, pressure, etc.) and the reactants involved in the reaction. Therefore, it's crucial to specify the conditions and reaction context when referring to enthalpy values.

For a chemical reaction C₂H₆ + 137 kJ → C₂H₄ + H₂, the chemical energy of the reactant and the chemical energy of the products are equal. Option D is correct.

In an exothermic reaction, energy is released as the reactants are converted to products. The negative sign on the enthalpy change (ΔH) indicates that the reaction is exothermic, meaning that energy is released by the system to the surroundings. This energy comes from the chemical energy of the reactants, and in this case, 137 kJ of energy are released.

The chemical energy of a substance is the energy stored in the bonds between its atoms. In this reaction, C₂H₆ (ethane) is converted to C₂H₄ (ethylene) and H₂ (hydrogen gas), which means that some of the bonds in the reactant molecule are broken and new bonds are formed in the product molecules.

The total amount of energy stored in the bonds of the reactants is equal to the total amount of energy stored in the bonds of the products, since energy cannot be created or destroyed, only converted from one form to another. Therefore, the chemical energy of the reactant and the chemical energy of the products are equal.

Hence, D. is the correct option.
