10. is C or gas and 11. is B liquid.
Answer:
4.46
Explanation:
Applying,
pH = -log(H⁺)....................... Equation 1
Where H⁺ = Hydrogen ion concentration of HCl solution
From the question,
Given: H⁺ = 3.5×10⁻⁵ M
Substitute these values into equation 1
pH = -log(3.5×10⁻⁵)
pH = 4.46
Hence the pH of HCl solution is 4.46
Answer:
Each element within a group has similar physical or chemical properties because of its atom's outermost electron shell (most chemical properties are dominated by the orbital location of the outermost electron).
Explanation:
A polar molecule is when the arrangement of the atoms in molecules are unequal where one end of the molecule has a positive charge while the other end has a negative charge. Examples of a polar molecule are water, ammonia, hydrogen sulfide and sulfur dioxide. The opposite is called a nonpolar molecule.
