f the original mass of wo3 is 37.0 g, how many grams of co2 must be collected from the reaction in order to infer that the solid that remains is pure tungsten

The compound that contains an ion with a +3 charge is FejPz. So option D is correct.

FejPz is an Iron(III) Phosphide, and the Iron ion in it has a +3 charge. Iron can have multiple oxidation states and the +3 oxidation state is one of them.

NOa is Nitrite, Nitrite is a neutral compound and doesn't contain any ion with a +3 charge

Mn_Oa is Manganese (IV) oxide, and Manganese in it has a +4 charge.

Molarity is a unit of concentration that expresses the number of moles of solute per liter of solution. To calculate the molarity of a solution made by diluting a concentrated solution, you can use the following formula:

Molarity = moles of solute / liters of solution

First, you have to calculate the number of moles of solute in the original solution, you can use the formula:

moles of solute = molarity x liters of solution

moles of solute = 18.0 M x 0.3 L = 5.4 moles

Then, you can use this value to calculate the molarity of the dilute solution:

Molarity of dilute solution = moles of solute / liters of solution

Molarity of dilute solution = 5.4 moles / 3.5 L = 1.54 M

So, the dilute solution has a molarity of 1.54 M.

To find the percent composition of Carbon in a substance, you need to calculate the percent of the total mass that is made up of Carbon.

The first step is to add up the masses of all the elements in the substance to get the total mass:

2.59 g Carbon + 39.56 g Sulfur + 43.03 g Oxygen = 85.18 g

Next, divide the mass of Carbon by the total mass and multiply by 100 to get the percent of the total mass that is Carbon:

(2.59 g Carbon / 85.18 g) * 100 = 3.03% Carbon

So, the percent composition of Carbon in the substance is 3.03%.

The lowest energy sublevel is always the 1s sublevel, which consists of one orbital

Because it is less effectively insulated, a 2s electron has a larger effective nuclear charge and is retained closer to the nucleus than a 2p electron, resulting in a lower energy for the 2s orbital.

The 1s sublevel, which consists of one orbital, is always the lowest energy sublevel. When the hydrogen atom is in its ground state, its solitary electron will occupy the 1s orbital.

An s-type subshell will have the lowest energy and an f-type subshell will have the greatest energy for the same main quantum number value, thus four electrons with the same principal quantum number. The energy of the electron increases as the secondary quantum number increases.

Metals are bright, opaque materials that efficiently conduct electricity and heat. Most metals are malleable and ductile, and they frequently have a higher density than other elements. When newly treated, polished, or broken, a material takes on a bright look and conducts heat and electricity reasonably well. Generally speaking, metals are malleable and ductile.

Electrons, neutrons, and protons are the building blocks of metals. The number of protons in an atom allows scientists to distinguish between atoms of different elements. The earth's crust contains around 25% metals.

The following formula is used to determine the heat(Q).

Q = m(s)(ΔT)

Here, m denotes the mass of the body, s denotes its specific heat, and T is the temperature change.

As a result, the heat lost by titanium metal equals the heat received by the water in the calorimeter.

Part B: The direction of an electric field that will balance the weight of a proton is upward.

Part C: The strength of an electric field that will balance the weight of a electron is approximately 9.8 x 10^16 N/C.

Part A: The weight of a proton is given by the equation F=mg, where F is force, m is the mass of proton and g is the acceleration due to gravity. The mass of proton is 1.67 x 10^-27 kg. So F = 1.67 x 10^-27 kg x 9.8 m/s^2 = 1.63 x 10^-26 N. The strength of an electric field required to balance the weight of a proton is the force acting on the proton divided by the charge of proton, which is approximately 9.8 x 10^9 N/C.

Part B: The weight of a proton is an upward force and the electric field that will balance this force will also be upward.

Part C: Similarly, the weight of an electron is given by the equation F=mg, where F is force, m is the mass of electron and g is the acceleration due to gravity. The mass of an electron is 9.11 x 10^-31 kg. So F = 9.11 x 10^-31 kg x 9.8 m/s^2 = 8.89 x 10^-31 N.

It would be more difficult for a ball bearing to fall through a beaker of hot honey than cold honey. This is because hot liquids are more viscous (thicker) than cold liquids, so the hot honey would provide more resistance to the ball bearing as it falls through.

Viscosity is a measure of a fluid's resistance to flow. Honey is a viscous liquid, which means it is thick and flows slowly. The viscosity of honey can be affected by temperature. As the temperature of honey increases, its viscosity decreases, which means it becomes thinner and flows more easily. Conversely, as the temperature of honey decreases, its viscosity increases, which means it becomes thicker and flows more slowly. So, hot honey is less viscous than cold honey.

The pH of hydroxide ion be if the hydrogen ion concentration was 1 x 10-6 m is 8.

You need to know the hydronium ion concentration in moles per litre to determine the pH of an aqueous solution molarity. The equation pH = - log [H3O+] is then used to determine the pH. Seven is the neutral pH. An increase in pH above 7 indicates an increase in alkalinity, whereas a fall in pH below 7 indicates an increase in acidity (hydrogen ions) (hydroxyl ions). Each pH unit corresponds to a concentration change of 10 times.

Total H+ is 1x 10–6M;

pH = -log[H+] =6; pOH = 14–6 = 8

(OH-)=3.2 x 10-8 M

So, pOH=-log(OH-)

Empirical formula is the most straightforward formula for a compound and provides the ratio of various atoms found in each compound molecule.

The empirical formula for the two compounds is CH₂. To determine the molecular formula, we need to know the molar mass of the compounds.

If the molar mass of compound A is 60.05 g/mol, and the empirical formula is CH₂, we can calculate the molecular formula by dividing the molar mass by the molar mass of the empirical formula.

60.05 g/mol / (12.01 g/mol + 2 x 1.01 g/mol) = 2.5

Therefore, the molecular formula for compound A is C₂H₅

Similarly, if the molar mass of compound B is 180.16 g/mol, and the empirical formula is CH₂, we can calculate the molecular formula by dividing the molar mass by the molar mass of the empirical formula.

Seven out of the twenty amino acids contain readily ionizable side chain groups. That means that at specific pH values, each side chain can participate in an acid-base reaction in which it can exchange a hydrogen atom with some other biomolecule. Since these side chains can form ions, that implies that they can also participate in forming ionic bonds. On top of these seven amino acids with ionizable side chains, all of the amino acids contain an ionizable alpha amino group and an alpha carboxyl group. The pKa value of each side chain group determines the pH value at which there will be equal concentrations of the acid and its conjugate base. The pKa value of the alpha amino group is 3.1 while the pKa value of the alpha amino group is 8.0.
