The naming binary covalent compounds, the element listed first will be the one that is more metallic.

Binary covalent compound are composed of two different elements (which is usually nonmetals). For example: ClF3 It contains 1 atom of chlorine and 3 atoms of fluorine. Binary compounds follow some rules: First element in the formula is given first, using the full name of the element’s and the second element is named as if it were an anion. Prefixes are used to denote the numbers of atoms which is present. When first element exists as a single atom, the prefix mono- is omitted. For example, CO is known as carbon monoxide rather than monocarbon monoxide.

Answer:

1 mole = 6.02 x 1023 atoms = 6,158.46 atoms

1 mole = 12 g

1Oz = 28.3495 g

Answer:Our formula for percent composition is:

Molar mass of element

----------------------------------- x 100

Molar mass of compound

So, lets find the molar mass of the compound as a whole before we begin. We do this by adding atomic masses from the periodic table.

Ca: 40.078

S: 32.065

O4: 63.996 (15.999 x 4)

To find our total mass, all we need to do is add those numbers together! Our molar mass of CaSO4 is 136.139 g/mol.

Now, lets use those individual masses and our total mass in the equation to find the percent composition of each element.

Ca: 40.078

      ----------        equals .294, and when we multiply that by 100 we get 29.44%

       136.139

The percent composition of calcium in CaSO4 is 29.44%.

S: 32.065

    -------------  equals .235, and when we multiply that by 100 we get 23.55%

     136.139

The percent composition of S in CaSO4 is 23.55%.

O4: 63.996

      -------------  equals .470, and when we multiply that by 100 we get 47.0%

       136.139

The percent composition of O4 in CaSO4 is 47%.

The number of moles present in 25.5g of Lead 2 Sulphide,PBS is 0.0839 moles.

Moles are small, burrowing mammals that have dark fur and small eyes. They are most active during the night, and spend most of their time digging and foraging for food. Moles have powerful front feet and claws that help them to move soil and dig tunnels. They feed mostly on small insects, worms, and grubs that live in the ground. Moles can be found throughout the world, and their populations vary according to the availability of food. They are important for aerating soil, and their tunnels can provide pathways for water to travel.

Molar mass of Lead 2 Sulphide,PBS = 303.82 g/mol
Number of moles = 25.5 g/ 303.82 g/mol
= 0.0839 moles.
Therefore, the number of moles present in 25.5g of Lead 2 Sulphide,PBS is 0.0839 moles.

The element Rhodium (Rh) has the electron configuration [Kr]4d⁶[K r] ⁴d⁶ and, as a result, forms a 3⁺ ion with that exact same name.

Rhodium, which has the chemical symbol Rh and atomic number 45, is an element. It is an extremely uncommon transition metal that is white in color, exceedingly hard, and resistant to corrosion. The platinum group metals include this precious metal. Naturally occurring 103Rh is the only isotope of this element.

Rarely does rhodium occur as a chemical compound in minerals like bowieite and rhodplumsite, but it does so frequently as a free metal or an alloy with other metals. It is extremely rare and therefore extremely expensive.

Similar to the other platinum group metals, rhodium can be mined from platinum or nickel ores. William Hyde Wollaston found it in 1803 in one of these ores and gave it the name "rose" after one of its chlorine derivatives, which is a deep pink.

At the very top of the nitrogen atom there are three dots, representing the three valence electrons of the nitrogen atom.

Valence electrons are the electrons that are present in the outermost shell of an atom. They are responsible for the chemical properties of the atom and determine how the atom will interact with other atoms in a chemical reaction. Valence electrons are important because they provide the atom with a certain degree of stability and determine its reactivity. Valence electrons are located in the outermost electron shell, so they are the most easily accessible to other atoms.

This feature explains why the molecule is polar because the three electrons create an uneven distribution of charge, giving the molecule a positive and negative end, making it polar.

A) Yes, it is possible for the temperature of a substance to rise without heat flowing into it. This can occur by a process called adiabatic heating.

B) No, the temperature of a substance does not necessarily have to change because heat flows into or out of it.

An adiabatic process can be described as a process in which no heat transfer takes place. This does not imply that the temperature is unchanging. This rather says that no heat is transferred through from the system.

Under adiabatic processes, when the volume of the gas decreases, the temperature increases. This results in the driving of temperature change cby work done on the gas and thus increases the internal energy of the gas.

The equilibrium constant, Kp, for a reaction can be determined by using the equilibrium concentrations (or partial pressures) of the reactants and products.

The equation for the equilibrium constant, Kp, for the reaction is:

Kp = [tex](PNH3)^2 * PCO2 / (PH2NCO2)^2[/tex]

In this case, the pressure of the solid ammonium carbamate is zero since it sublimes, and the total pressure is given as 0.116 atm.

So the total pressure of the gases, NH3 and CO2, at equilibrium is 0.116 atm.

Since we don't know the individual pressures of each gas we can assume that the pressure of NH3 is x and the pressure of CO2 is (0.116-x) atm.

Therefore, the equilibrium constant, Kp, is equal to  [tex](x)^2 * (0.116-x) / (0)^2 = x^2 * (0.116-x)[/tex]  

Note that in order to calculate the exact value of Kp, the concentrations or partial pressures of each gas at equilibrium need to be known.

The molarity of the solution of 0.065 grams of NaCl in enough ethanol [tex](CH_3CH_2OH)[/tex] to give 100 ml of solution is 0.11 M.

The molarity of a solution is defined as the number of moles of solute per liter of solution. To calculate the molarity, we need to know the number of moles of solute present in the solution and the volume of the solution.

First, we need to find the number of moles of solute. We can do this by using the formula:

moles of solute = mass of solute / molar mass of solute

The molar mass of NaCl is 58.44 g/mol, so we can use this to calculate the number of moles of NaCl in 0.065 g of NaCl:

moles of NaCl = 0.065 g / 58.44 g/mol = 0.0011 mol

Next, we need to find the volume of the solution. We know that the solution has a volume of 100 ml. We will assume that the density of ethanol is close to the density of water which is 1g/ml, so we can assume that the volume of the solution is equal to the mass of the solution.

Finally, we can calculate the molarity of the solution:

molarity = moles of solute/liters of solution

molarity = 0.0011 mol / 0.1 L = 0.11 M

So the molarity of the solution is 0.11 M.

The mass of KCl produced is equal to 0.020 mol of KCl multiplied by the molar mass of KCl (74.55 g/mol), which is 1.491 g.

Molar mass is the mass of one mole of a substance, and it is expressed in grams per mole (g/mol). It is calculated by summing the relative atomic masses of all the atoms in a molecule. The molar mass of a compound can be used to calculate the amount of a substance in moles, using the formula: moles = mass (g) / molar mass (g/mol). Knowing the molar mass of a substance can be useful in many areas of chemistry, such as stoichiometry calculations and determining the mass percent composition of a compound.

When heated, 2.5 g of KClO3 completely decomposes to KCl and O2.
Since the molar mass of KClO3 is 122.55 g/mol, 2.5 g of KClO3 is equal to 0.020 mol.
Since the reaction is 2KClO3 --> 2KCl + 3O2, 0.020 mol of KClO3 produces 0.030 mol of O2.
The mass of O2 produced is therefore equal to 0.030 mol of O2 multiplied by the molar mass of O2 (32.00 g/mol), which is 0.960 g.
