<span>The amount of dissolved salt in the liquid sample is measured and reported as salinity. The salinity is usually measured in parts per thousand (ppt). The salinity of ocean averages 35 ppt while that of the river averages 0.5 ppt or less. In other terms, the word salinity is the saltiness. </span>

<span>The correct answer is C. The measure of the amount of dissolved salt in a liquid sample is called sallinity. It defiens how much salty is a solution or how much amount of salt is present in the solution. It is measured in thousand part per gram of the sea water.</span>

Calculate the hydroxide ion concentration [oh-] for human urine (ph = 6.2). notice this is about hydroxide.

igomit [66]

[OH⁻] = 1.6 × 10⁻⁸ mol / dm³

<h3>Explanation</h3>

By definition, $[\text{H}^{+}] = 10^{-\text{pH}}$ , where $[\text{H}^{+}]$ is the concentration of proton in the solution.

pH = 6.2 for this solution. As a result, $[\text{H}^{+} = 10^{-6.2} = 6.31 \times 10^{-7} \; \text{mol} \cdot \text{dm}^{-3}$ .

$[\text{H}^{+}] \cdot [\text{OH}^{-}] = \text{K}_w$ , where $[\text{OH}^{-}]$ the concentration of hydroxide ions and $\text{K}_w$ is the dissociation constant of water.

$\text{K}_w = 10^{-14} \; \text{mol}\cdot \text{dm}^{-3}$ at 0.10 MPa and 25 °C. As a result, $[\text{OH}^{-}] = \text{K}_w / [\text{H}^{+}] = 10^{14} / (6.31 \times 10^{-7}) = 1.6 \times 10^{-8} \; \text{mol}\cdot \text{dm}^{-3}$ .

What information can a mineralogist learn from testing the mass and volume of a mineral?

Vesna [10]

Minerals can be identified by their physical characteristics. The physical properties of minerals are related to their chemical composition and bonding. Some characteristics, such as a mineral’s hardness, are more useful for mineral identification. Color is readily observable and certainly obvious, but it is usually less reliable than other physical properties.

Heats of reaction calculated from bond energies and from heats of formation are often, but not always, close to each other.a. In

postnew [5]

Answer:

45.7kj

Explanation:

To calculates the heats of reaction from heats of formation:

∆Hr=£∆Hp -£∆Hr

= £∆Hch3ChOH - £∆HCh2h2+h20

=(-235.1kj)-(+52.47kj/kg + (-241.8kj/kg)

∆H = 45.71kj/kg
