What is a polar bond

Chemistry
1 answer:
mariarad [96]3 years ago
3 0

Answer: A polar bond is a covalent bond between two atoms where the electrons forming the bond are unequally distributed.

Example: A water molecule, abbreviated as H2O, is an example of a polar covalent bond. The electrons are unequally shared, with the oxygen atom spending more time with electrons than the hydrogen atoms.

What is the equation if the product is CaOH+(aq)?
zavuch27 [327]
The product is called carbon monohydroxide (CaOH+) ion. This is the only product if the solution is alkaline. The reactants are calcium (Ca2+) and hydroxide (OH-) ions. If the solution is acidic, hydrogen (H+) ion is also included in the product side of the equation.

Ca2+(aq) + OH-(aq) -> CaOH+(aq)

If f(x)=x^2 and g(x)=2x+3, what is f(g(x))
IgorC [24]

Answer:

\huge\boxed{f(g(x)) = 4x^2 + 12x + 9}

Explanation:

In its raw form, function notation essentially represents an equation with only one unknown variable, expressed in terms of another.  Thus, f(x) = x² + 7x can be expressed as

g(x) = 2x + 3

f(g(x)) = (2x + 3)²

f(g(x)) = 4x² + 12x + 9

Hope it helps :) and let me know if you want me to elaborate.

Mg(OH)2 is a sparingly soluble compound, in this case a base, with a solubility product, Ksp, of 5.61×10−11. It is used to contr
VLD [36.1K]

Answer:

1.27 x 10⁻⁴M

Explanation:

For a 2 to 1 ionization ratio, solubility in pure water can be calculated using the formula S = ∛(Ksp/27) = ∛(5.61 x 10⁻¹¹/27 = 1.27 x 10⁻⁴M.

Mg(OH)₂ ⇄ Mg⁺² + 2OH⁻ => Ksp = [Mg⁺²][OH⁻]² = (x)(2x)² = 4x³

Solve for 'x' => x = Solubility = ∛Ksp/4
