Question 10
Alex_Xolod [135]

Answer:

56.8 g

Explanation:

Your first conversion factor is the molar mass of H2O to convert from grams of water to moles. Your second conversion factor is the mole ratio of 2 mol C2H10 for every 10 mol H2O. Your last conversion factor is the molar mass of C2H10 to convert from moles back to grams.

150. g H2O • (1 mol H2O / 18.02 g H2O) • (2 mol C2H10 / 10 mol H2O) • (34.1 g C2H10 / 1 mol C2H10) = 56.8 g C2H10

At 500 K, the reaction is at equilibrium with the following concentrations. [PCI5]= 0.0095 M [PCI3] = 0.020 [CI2] = 0.020 M What
Ad libitum [116K]
Although it is omitted, the reaction equation for the decomposition of phosphorus pentachloride is:
PCl₅ → PCl₃ + Cl₂

The equilibrium constant's equation then becomes:
Kc = [PCl₃]*[Cl₂] / [PCl₅]
Kc = (0.02 * 0.02) / 0.0095
Kc = 0.042

The equilibrium constant is 0.042.

All compounds of carbon are made by _____.
Andrew [12]

Answer:

Covalent bonding

Explanation:

Covalent bonding is the bond that holds all compound that are formed by carbon.

It is a very strong intermolecular bond that holds the structure of carbon compounds in place.

Principally, covalent compounds are formed by sharing of electrons between contributing atoms.

Covalent bonds are the strongest bond types. A reason for this conclusion can be see in case of diamond. Here, there is a covalent linkage between the atoms present and the strength of these bonds is responsible for how strong the diamond crystal is
