Answer:

You're going to have to convert the grams to moles, and then multiply that with the ratio of heat produced to the ratio of CH4

Answer:

2 KCl(s)

Explanation:

just took the exam

Taking into account the reaction stoichiometry, 9717.75 grams of oxygen gas  are  produced  when 2.43×10⁴ grams of KClO₃  are  completely  reacted.

The balanced reaction is:

2 KClO₃ →  2 KCl + 3 O₂

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:

The molar mass of each compound is:

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

Then you can apply the following rule of three: if by reaction stoichiometry 245.1 grams of KClO₃ form 96 grams of O₂, 2.43×10⁴ grams of KClO₃ form how much mass of O₂?

[tex]mass of O_{2} =\frac{2.43x10^{4} grams of KClO_{3} x 96 grams of O_{2}}{245.1grams of KClO_{3} }[/tex]

mass of O₂= 9517.75 grams

In summary, 9717.75 grams of oxygen gas  are  produced  when 2.43×10⁴ grams of KClO₃  are  completely  reacted.

By definition of atomic number, the correct answers are:

You have to know that atoms are made up of a nucleus made up of protons and neutrons, and a shell made up of electrons. Protons are positively charged, while neutrons are electrically neutral (that is, they have zero charge). Therefore the atomic nucleus always has a positive charge. On the other hand, electrons are negatively charged.

The atomic number is the total number of protons that make up the atomic nucleus of a given chemical element and is represented by the letter Z.

An atom is naturally neutral and has the same number of electrons and protons.

The atomic number is used to classify the elements within the periodic table of elements, going from the smallest to the largest number of protons in the nucleus as you progress through the rows and columns of the table. That is, as you travel a period (row) from left to right and as you travel a group (column) from top to bottom, the atomic number increases.

In summary, the correct answers are:

Answer:

The answer is "The number of protons is given by the atomic number, which increases by one moving from left to right across each row of the periodic table."

Explanation:

If you look at the periodic table, the elements atomic numbers increase from left to right by one. Therefore, the protons also increase by one from left to right because the number of protons in an element is the same as the atomic number.

Answer: D. Scientific investigation aims to design and implement an experiment to learn new information, whereas technological development aims to design a product to solve a problem.

Explanation:

The concentration of all solute species in the solution are:

[tex][Mg^{2+} ] = 0.631 M \\ [Pb] = 1.0 \times 10^{-5} M \\[Cl^{-} ] = 1.26 M[/tex]

MgCl₂ (0.631 M) is a strong electrolyte that dissociates according to the following equation.

MgCl₂(aq) ⇒ Mg²⁺(aq) + 2 Cl⁻(aq)

Considering the molar ratios, the initial concentrations of Mg²⁺ and Cl⁻ are:

[tex]\frac{0.631 mol MgCl_2}{L} \times \frac{1molMg^{2+} }{1molMgCl_2} = \frac{0.631molMg^{2+}}{L} \\\frac{0.631 mol MgCl_2}{L} \times \frac{2molCl^{-} }{1molMgCl_2} = \frac{1.26molCl^{-}}{L}[/tex]

Cl⁻ is a common ion between MgCl₂ and PbCl₂. To consider the solution equilibrium for PbCl₂ (a sparingly soluble salt), we will make an ICE chart.

        PbCl₂(s) ⇄ Pb²⁺(aq) + 2 Cl⁻(aq)

I                            0               1.26

C                          +x              +2x

E                            x             1.26+x

The solubility product constant, Ksp, is:

[tex]Ksp = 1.6 \times 10^{-5} = [Pb^{2+} ][Cl^{-} ]^{2} = (x) (1.26+x)^{2}[/tex]

Since 1.26 >>> x, 1.26 + x ≈ 1.26.

[tex]Ksp = 1.6 \times 10^{-5} = (x) (1.26)^{2}\\x = 1.0 \times 10^{-5}[/tex]

The concentration of all solute species in the solution are:

[tex][Mg^{2+} ] = 0.631 M\\ [Pb] = x = 1.0 \times 10^{-5} M\\[Cl^{-} ] = 1.26+x = 1.26 M[/tex]

Answer:

Carbon-14

Explanation:

It is because it have 6 protons and 8 neutrons which are added together to form an atomic mass of 14.

The mass number of an isotope is the sum of the number of protons and number of neutrons hence the correct answer is carbon-14.

Isotopes are atoms of the same element that has the same number of protons but different number of neutrons.

The atomic number is the same as the number of protons in the atom. Since there are six protons in the atom, the element must be carbon.

There are eight neutrons meaning that the mass  number is 8 + 6 = 14

Therefore, the isotope is carbon-14.

Answer:

Explanation:

its upside down but I'm 99% sure

The correct answer is; "The frozen metal was discovered through biased research practices."

Scientific research is based on standard practices and not on personal bias hence they should not have taken a decision based on the frozen metals. Bias prevents a researcher from taking an objective look at experimental observations before arriving at a conclusion.

The greatest pitfall that must be avoided when conducting a scientific study is bias.

A bias is introduced when there is a disparity between observation and interpretation of data in a scientific study.

In the case of this question, the researchers already wanted to establish the possibility of obtaining a carbonless fuel. Their minds were so clouded with this bias that they forgot to thoroughly investigate the pieces of frozen metal thereby arriving at a lobe-sided, unscientific conclusion. This makes their work, "bad" science.

Answer:

it would be A The conditions of the experiment are not replicate able or repeatable.

Explanation:

A team of researchers is working on a project to make a new kind of carbonless fuel. During their experiment, there is an explosion that destroys the lab. While they are cleaning the debris, they discover three pieces of frozen metal. The researchers were excited to report that they had discovered a fuel that burns so clean it becomes cold. Other scientists attempt to make the carbonless fuel but are unsuccessful. Which statement best explains why this scenario represents "bad" science?

The conditions of the experiment are not replicable or repeatable.

The process of making clean fuel is known due to the explosion.

The frozen metal was discovered through biased research practices.

The result of clean fuel production, the frozen metal, is not observable.

Answer:

why are people s opinions and prejudices her greatest obstacles

The chemical formula of water is H2O, and the chemical formula of carbon dioxide is CO2. This means that water has 2 atoms of hydrogen and 1 atom of oxygen, which carbon dioxide has 1 atom of carbon and 2 atoms of oxygen. The only similar atom that the two molecules have in common is oxygen. CO2 has one more atom of oxygen than H2O. Hope this helps!

H2O is water. CO2 is CD.

To convert from mass concentration to molar concentration we use the formula;

Mass concentration = molar concentration * molar mass

Molar concentration of Na2SO4 = 0.700 M

Molar mass of Na2SO4  = 2(23) + 32 + 4(16) = 142 gmol-1

Hence;

Mass concentration = 0.700 M * 142 gmol-1

Mass concentration = 99.4 g/mol

A transition occurs when an electron absorbs energy and moves from one energy level to another.

Let us recall the formula;

E = hc/λ

h= planks constant = 6.6 * 10^-34 Js

c = speed of light = 3 * 10^8 ms-1

λ = wavelength =

We can see from the question that the exponent in the value for the wavelength was not properly rendered hence we can not be able to substitute values and obtain a numerical answer for the energy of the infrared radiation.

However, if all the values are properly substituted, then the energy of the infrared radiation can conveniently be obtained.
