Answer:

\large \boxed{10^{-8}\text{ mol/L}}

Explanation:

pH = -log[H⁺]

\text{[H$^{+}$]}= 10^{-\text{pH}} \text{ mol/L} = \mathbf{10^{-8}}\textbf{ mol/L}\\\text{The hydrogen ion concentration is $\large \boxed{\mathbf{10^{-8}}\textbf{ mol/L}}$}

Answer:

10−8 M.

Explanation:

In this problem we are given pH and asked to solve for the hydrogen ion concentration. Using the equation, pH = − log [H+] , we can solve for [H+] as,

− pH = log [H+] ,

[H+] = 10−pH,

by exponentiating both sides with base 10 to "undo" the common logarithm. The hydrogen ion concentration of blood with pH 7.4 is,

[H+] = 10−7.4 ≈ 0.0000040 = 4.0 × In this problem we are given pH and asked to solve for the hydrogen ion concentration. Using the equation, pH = − log [H+] , we can solve for [H+] as,

An unsaturated solution is formed when 80 grams of a salt is dissolved in 100 grams of water at 40. This salt could be ?
LekaFEV [45]
A simple way to go about this is that we look at the solubility curve, on the x axis we first look at the temperature and then the corresponding value of solute/100g H2O on the y axis, from the 4 curves above only NaNO3 has a curve that can accommodate  80g of salt at 40 without being Saturated since at 40 degrees it can accommodate 105g of salt to become completely Saturated.

A substance that does not allow x-rays to pass through is described as being
horsena [70]

A substance that is impenetrable by x-rays is described as being radiopaque.

Radiopaque substances will not allow x-rays and or other forms of radiations to pass through them.

Instead, they absorb or block the rays and when used in radiology, they appear white or light gray on photographic films.

Radiopaque materials are applied in generating ultrasound images and other forms of clinical procedures.

More on radiopaque materials can be found here: brainly.com/question/10583205?referrer=searchResults
