1. All the individuals of one type of clownfish ( e. species) living in a reef compose which level of organization?

(b) What is the pOH of 1.35x10⁻³ M HCl? Is the solution neutral, acidic, or basic?

nika2105 [10]

The pOH scale is similar to the pH scale in that a pOH of 7 is indicative of a neutral solution. A basic solution has a pOH less than 7, while an acidic solution has a pOH of greater than 7

<h3>What is pOH scale?</h3>

Based on the relative concentration of hydrogen and hydroxyl ions, the pH and pOH scales are used primarily in chemistry, biology, and soil science to describe and measure the acidity and basicity of neutral, acidic, and basic solutions in water.

The terms pH and pOH scale are frequently used and crucial for determining the chemical, biological, and soil health by converting the values of hydrogen or hydroxyl ion concentrations or by utilizing pH paper and meters.

The pH scale or chart, which measures the concentration of hydrogen and hydroxyl ions in acidic and alkaline solutions, was initially developed by Sorensen.

How many grams of aluminum sulfate: Al2(SO4)3 , would be formed if 250 g of H2SO4 react with aluminum? The reaction is: 2Al + 3H

NikAS [45]

Answer:

290.8 grams of aluminium sulfate (Al2(SO4)3) will be produced.

Explanation:

Step 1: Data given

Mass of H2SO4 = 250 grams

Molar mass H2SO4 = 98.08 g/mol

Step 2: The balanced equation

2Al + 3H2SO4 → Al2(SO4)3 + 3H2

Step 3: Calculate moles H2SO4

Moles H2SO4 = mass H2SO4 / molar mass H2SO4

Moles H2SO4 = 250 grams / 98.08 g/mol

Moles H2SO5 = 2.55 moles

Step 4: Calculate moles Al2(SO4)3

For 2 moles Al we need 3 moles H2SO4 to produce 1 mol Al2(SO4)3 and 3 moles H2

For 2.55 moles H2SO4 we'll have 2.55/3 = 0.85 moles Al2(SO4)3

Step 5: Calculate mass Al2(SO4)3

Mass Al2(SO4)3 = moles Al2(SO4)3 * molar mass

Mass Al2(SO4)3 = 0.85 moles * 342.15 g/mol

Mass Al2(SO4)3 = 290.8 grams

290.8 grams of aluminium sulfate (Al2(SO4)3) will be produced.

whats the name of the group 13 of the periodic table? 14 is cristalogens and 15 pnictogens and 16 chalcogens and 17 halogens and

qaws [65]

Answer:

Boron family.

Explanation:

Group 13 is called boron family.

It consist of five members boron, aluminum, gallium, indium and thallium.

Boron is semi metal while other members are metals.

Boron hydrates are used to make organic compounds.

Al is soft metal and aluminum oxides are widely used as thermal insulator.

Aluminum sulfate is also very important commercial compound used in sizing paper.

Gallium is also very important element of this group. It form gallium arsenide which is used to convert the light into electricity.

Indium is malleable soft metal which is used in optical instruments.

Thallium is highly toxic and for the long period of time it as used as insect killing poison.
