Atomic mass Cu = 63.546 a.m.u
63.546 g ---------------- 6.02x10²³ atoms
22 g --------------------- ??
22 x (6.02x10²³ ) / 63.546 => 2.08x10²³ atoms
hope this helps!
Answer:
Benzoic acid
Explanation:
The strength of an acid is principally a measure of its dissociative capabilities in aqueous solutions. While strong acids dissociate completely in solution, weak acids dissociates only partially.
The relative strength of an acid can be obtained from its pKa value. The pKa value is the negative logarithm of the concentration of the Ka value.
Stronger acids have a pKa value usually negative. This is a pointer to the fact that the lower the pKa value, the stronger the strength of the acid in question.
Relatively therefore, Benzoic acid is stronger than acetic acid because it has a lesser value for pKa
Answer:
1520 mmHg
Explanation:
Let's solve this by a factor conversion:
1 atm → 760 mmHg
2 atm . 760 mmHg / 1 atm = 1520 mmHg
Glucose is the starting molecule for glycolysis.
Answer is: It is likely a gas or liquid at room temperature.
Carbon tetrachloride or tetrachloromethane (CCl₄) is an organic compound with nonpolar covalent chemical bonds.
1) Carbon tetrachloride is a colourless liquid, used in fire extinguishers.
2) Because it is nonpolar, it is not soluble in polar water.
3) It can not conduct electricity because it is nonpolar compound.
4) Melting point is low -23°C.
