Answer:

You're in my science class wth

Explanation:

For instance farmers are using basic fertilizers to neutralize an acid soil –which is harmful for the plants- while basic solutions are added in the chimneys of factories to neutralize the acid smoke that they produce –avoiding the catastrophic effects of the acid rains. Acid released in the environment from industry creates acid rain which has many ecological effects. Acid rain makes waters acidic, and causes them to absorb the aluminium that makes its way from soil into lakes and streams. This combination makes waters toxic to crayfish, clams, fish, and other aquatic animals.

Calcium and bromine have formed a bond. Leading up to this, calcium gave up electrons. It was a(n)
scZoUnD [109]
Leading up to this, calcium gave up 2 valence electrons and thus was denoted as a cation. These 2 electrons were transferred to bromine, which received an overall negative charge because of the addition of 2 valence electrons in its valence shell, and thus formed a negatively charged ion, an anion.

Both formed an ionic bond, due to the electrostatic charge of attraction between the 2 oppositely charged ions. If many ions of Ca and Br are present and numerous ionic bonds have formed it will undergo an arrangement which is that of an ionic lattice, type of structure.

Please help me with this question
Inessa05 [86]

From the calculation, the concentration in parts per billion is 6 ppb.

<h3>What is ppb?</h3>

The term ppb refers to the concentration of a substance in parts per billion. We obtain the ppb using the formula;

Mass of solute/ Mass of solution * 10^9

Now, 1L = 1000cm^3 = 1000 g

The concertation in ppb = 6 * 10^-6 g/1000 g * 10^9

= 6 ppb
