Calculate the mass of carbon atoms in 1.24 kg of C2H2

Explanation:

H is 1 mole of hydrogen

2H is 2 moles of hydrogen

Answer:

Volume = 3.4 L

Explanation:

In order to calculate the volume of CO₂ produced when 15.2 g of CaCO₃ is heated, we need to first write out the balanced equation of the thermal decomposition of CaCO₃:

CaCO₃ (s) + [Heat] ⇒ CaO (s) + CO₂ (g)

Now, let's calculate the number of moles in 15.2 g CaCO₃:

mole no. = \(\mathrm{\frac{mass}{molar \ mass}}\)

                 = \(\frac{15.2}{40.1 + 12 + (16 \times 3)}\)

                 = 0.1518 moles

From the balanced equation above, we can see that the stoichiometric molar ratios of CaCO₃ and CO₂ are equal. Therefore, the number of moles of CO₂ produced is also 0.1518 moles.

Hence, from the formula for the number of moles of a gas, we can calculate the volume of  CO₂:

mole no. = \(\mathrm{\frac{Volume \ in \ L}{22.4}}\)

⇒ \(0.1518 = \mathrm{\frac{Volume}{22.4}}\)

⇒ Volume = 0.1518 × 22.4

                 = 3.4 L

Therefore, if 15.2 g of CaCO₃ is heated, 3.4 L of CO₂ is produced at STP.

To graph the function g(x) = f(-x), you can start with the graph of f(x) and then reflect it about the y-axis.

To find the graph of the function g(x) = f(-x), we can start with the graph of the function f(x) and then reflect it about the y-axis.

If the graph of f(x) is symmetric with respect to the y-axis, meaning it is unchanged when reflected, then g(x) = f(-x) will have the same graph as f(x).

However, if the graph of f(x) is not symmetric with respect to the y-axis, then g(x) = f(-x) will be a reflection of f(x) about the y-axis.

In either case, the resulting graph of g(x) = f(-x) will be symmetric with respect to the y-axis.

Answer:

El termómetro expuesto directamente al sol medirá la temperatura del aire circundante y la radiación solar, pero no la temperatura del sol en sí.

Answer:

The speed of molecules in a gas is directly proportional to the square root of the temperature and inversely proportional to the square root of the molar mass.

Since both gases are at the same temperature, we only need to compare their molar masses.

The molar mass of carbon dioxide (CO2) is 44 g/mol and the molar mass of hydrogen (H2) is 2 g/mol.

Therefore, the square root of the molar mass of hydrogen is smaller than the square root of the molar mass of carbon dioxide.

This means that the speed of hydrogen molecules is greater than the speed of carbon dioxide molecules at the same temperature.

The statement "Each member of a homologous series differs from its nearest neighbors by 14 amu" is true of members about a homologous series.

In organic chemistry, a homologous series unveils itself as a sequential assembly of compounds exhibiting an identical functional group, boasting akin chemical traits. Within this series, the constituents can either sport a branched or unbranched structure, or deviate through the molecular formula of CH2 and a molecular mass variation of 14u.

Explanation:

It is not important to accurately measure the amount of HCl placed in the eudiometer tube since HCl will be added in excess to react with all the moles of Mg.

In gas stoichiometry, through the method of displacement of a liquid (generally water), the gaseous byproduct is collected inside a long, thin graded glass tube called a eudiometer.

If we consider a reaction between Magnesium and Hydrochloric acid to give a product known as magnesium chloride and hydrogen gas, we can have the chemical equation represented as:

\(\mathbf{Mg_{(s)} + 2 HCl _{(aq)} \to MgCl_{2(aq)} + H_{2(g)}}\)

From the above reaction, for each mole of Magnesium taking place in the reaction, 1 mole of hydrogen gas is also produced.

Thus, we can have a prediction that HCl can always be added in excess in order for us to react to all the moles of solid magnesium, hence, it is not important to measure the moles of HCl since it will be added in excess.

The balanced equation of the precipitation reaction would be \(3Cu(NO_3)_2 + 2K_3PO_4 -- > Cu_3(PO_4)_2 + 6KNO_3\)

Precipitation reactions are reactions involving two aqueous salts leading to the production of, at least, one insoluble salt or a precipitate.

In the reaction given, \(K_3PO_4\) reacts with \(Cu(NO_3)_2\). The two reactants are soluble and will exchange radicals during the reaction to produce \(Cu_3(PO_4)_2\), an insoluble salt or a precipitate, and \(KNO_3\), a soluble salt.

In order to balance the equation, it must be made to obey the law of conservation of atoms. According to the law, atoms of elements that participate in chemical reactions may change forms but are always conserved in terms of number.

In other words, the number of atoms of each element in the reactants must be equal to their respective numbers in the products.

Thus, the equation that shows that the precipitation reaction obeys the law of conservation of atoms is \(3Cu(NO_3)_2 + 2K_3PO_4 -- > Cu_3(PO_4)_2 + 6KNO_3\)

The mass of the carbon dioxide is  49.72 g from the calculation done.

The phrase "mole fraction," which is often referred to as "molar fraction" or "amount fraction," is used to describe the proportions of a mixture's components. It is an intangible quantity that expresses the proportion between the moles of a given component and the total moles in the combination.

We know that;

Number of moles of ethanol = 9.2/46 g/mol

= 0.2 moles

Now;

Number of moles of water = 216.0 g/18 g/mol

= 12 moles

Mole fraction of water = Number of water/ Total number of moles

0.9 = 12/12 + 0.2 + x

0.9(12.2 + x) = 12

10.98 + 0.9x = 12

Explanation:

The amount of hydrogen left over is 9.683 g.

The balanced chemical equation for the reaction between molecular hydrogen (H₂) and oxygen (O₂) to form water (H₂O) is:

2H₂ + O₂ -> 2H₂O

The equation shows that two moles of hydrogen react with one mole of oxygen to produce two moles of water.

To determine which reactant is left over, we need to calculate how much of each reactant is required for the reaction and compare it with the actual amount provided.

The reactant that is not completely consumed will be left over.

First, we need to convert the masses of hydrogen and oxygen to moles using their respective molar masses:

Molar mass of hydrogen (H2) = 2.016 g/mol

Molar mass of oxygen (O2) = 31.9988 g/mol

Number of moles of hydrogen = 10.0 g / 2.016 g/mol = 4.96 mol

Number of moles of oxygen = 10.00 g / 31.9988 g/mol = 0.3125 mol

From the balanced equation, we can see that 2 moles of hydrogen react with 1 mole of oxygen.

Therefore, the number of moles of oxygen required to react with 4.96 moles of hydrogen is:

0.5 x 4.96 = 2.48 mol

Since we only have 0.3125 mol of oxygen, it is the limiting reactant, and hydrogen is in excess.

To find out how much hydrogen is left over, we need to calculate how much hydrogen was used in the reaction:

Number of moles of water produced = Number of moles of oxygen used = 0.3125 mol

Number of moles of hydrogen used = 0.5 x 0.3125 = 0.15625 mol

The total number of moles of hydrogen we started with was 4.96 mol, and 0.15625 mol of hydrogen was used in the reaction.

Therefore, the amount of hydrogen left over is:

4.96 mol - 0.15625 mol = 4.80375 mol

Finally, we can convert this back to a mass:

Mass of hydrogen left over = 4.80375 mol x 2.016 g/mol = 9.683 g

The name of the salt tells us that:

a) there is just one other element combined with the metal by looking at the suffix of the salt's name.

b) the presence of oxygen in a salt can be indicated by the name of the salt.

a) The name of a salt can tell us that there is just one other element combined with the metal by looking at the suffix of the salt's name. If the salt name ends in "-ide," it indicates that the salt is composed of a metal and a single non-metal element.
For example, sodium chloride (NaCl) and potassium bromide (KBr) are salts where the metal (sodium and potassium) is combined with a single non-metal element (chlorine and bromine, respectively). The "-ide" suffix suggests the presence of only one other element in the salt.

b) The presence of oxygen in a salt can be indicated by the name of the salt. If the salt name includes the element oxygen, it suggests that oxygen is present in the salt compound.
For example, sodium carbonate (Na₂CO₃) and calcium sulfate (CaSO₄) contain the element oxygen in their chemical formulas. The presence of oxygen in the salt is implied by the name and the combination of elements in the compound.

Therefore, the name of salt tells us that there is just one other element combined with the metal and there is oxygen present in the salt

Isotopes are atoms with the same number of protons or atomic umber, but differing numbers of neutrons. They differ in mass, which affects their physical characteristics even if they have nearly identical chemical properties.

There is no elemental decay in stable isotopes. In contrast, unstable radioactive isotopes, like 14C, will decay into other elements.
