Answer:
the products are more stable than the reactants
Explanation:
Covalent Bonding
Ionic bonds are characterized by a transfer of electrons between elements to form a stable compound. These bonds typically form in compounds consisting of a metal and a nonmetal, which are positively and negatively charged respectively.
Covalent bonds are characterized by a sharing of electrons between the elements in the compound. Covalent bonds are formed between nonmetals and in many inorganic compounds as well.
Metallic bonding, as the name suggests, is formed between metals.
Since phosphorus pentoxide consists of 4 phosphorus atoms and 10 oxygen atoms, and both of which are categorized as nonmetals, phosphorus pentoxide is therefore, bonded covalently.
Answer:
1.36moles
Explanation:
Given parameters:
Pressure of gas = 1.2atm
Volume of gas = 21liters
Temperature of gas = 145°C, in Kelvin gives 273 + 145 = 418K
Unknown:
Number of moles of the gas = ?
Solution:
To solve this problem, we are going to use the ideal gas equation which combines the three gas laws; Boyle's law, Charles's law and Avogadro's law.
Mathematically, it is given as;
PV = nRT
where;
P is the pressure of gas
V is the volume of gas
n is the number of moles
R is the gas constant = 0.082
T is the temperature
Substitute the values and solve for n;
1.2 x 21 = n x 0.082 x 418
solving for n;
n = 1.36moles
Answer:
C
Explanation:
an impure substance made through chemical process
First find the molar mass of C6H12O6 to convert from grams to moles. Divide grams by the molar mass to get moles.
molar mass = 6(12.01) + 12(1.008) + 6(16) = 180.156 g/mol
0.017 g / 180.156 g/mol = 0.000094 mol C6H12O6
Molarity = mol/L
You’re solving for Liters of solvent.
L = mol/Molarity
mol = 0.000094
Molarity = 2.00
L = 0.000094/2.00 = 0.000047 L = 0.047 mL
