what is the chemical equation for this?

The charge of phosphate : 3-

Oxidation is an increase in oxidation number, while reduction is a reduction in oxidation number.

The formula for determining Oxidation Numbers in general:

1. Single element atomic oxidation number = 0.

Group IA (Li, Na, K, Rb, Cs, and Fr): +1

Group IIA (Be, Mg, Ca, Sr and Ba): +2

Group IIIA(Al, B) : +3

H in compound = +1, except metal hydride compounds (Hydrogen which binds to groups IA or IIA) oxidation number H = -1, for example, LiH, MgH₂, etc.

2. Oxidation number O in compound = -2, except OF2 = + 2 and in peroxide (Na₂O₂, BaO₂) = -1 and superoxide, for example KO₂ = -1/2.

3 The oxidation number in an uncharged compound = 0,

Total oxidation number in ion = ion charge, Example NO₃⁻ = -1

Compound AlPO₄ :

The oxidation number in an uncharged compound = 0

Since the charge of Al as group 3A (or group 13) is +3, while the AlPO₄ compound is a polyatomic compound (consisting of polyatomic ions PO₄ and Al), the PO₄ charge:

charge Al + charge PO₄ = 0

+ 3 + charge PO₄ = 0

charge PO₄ = -3

Answer:

Ephemerals

Explanation:

The first plants to move into the new bare ground after a wildfire are wildflowers or “weeds.” These fast-germinating, leafy herbaceous plants are also known as “forbs” or “ephemerals.” They quickly germinate, grow and produce a new crop of seeds.

A learned behavior is a behavior that develops during an animal’s lifetime.

Examples of learned behaviors include tying one’s shoes or solving a math problem.

An inherited behavior is a behavior that an animal is born with.

An example of an inherited behavior is a bird building a nest.

Explanation:

Learned behaviors are those which are gradually developing in us through learning at different ages and it takes time. Inherited behaviour is innate to us which are incorporated with us by birth.

An organism develops a learned behavior as a result of experience. In contrast to learned actions, inherent behaviors are genetically preprogrammed and can be carried out without any prior knowledge or instruction.  

Certain behaviors have features that are both acquired and innate. Zebra finches, for instance, have a genetic predisposition to learn a song, but the song they sing is influenced by what they hear from their dads.

Inherited behaviors are inherited from parents to their offsprings. Such as  similar nature in sound, angriness, some diseases etc. They are not gathered from any experience and are accompanied by birth.

Explanation: i just got the question right

In scientific notation, often known as power-of-10 notation, extremely big and small numbers are written. Scientists write very large numbers by express the numbers using scientific notation.

Numbers that are either too large or too little to be readily stated in decimal form can be expressed using scientific notation. It is also known as standard form in the UK and scientific form, standard index form, and standard form.

The main goal of scientific notation is to simplify computations using numbers that are abnormally big or tiny. The following examples demonstrate how all the digits in a number in scientific notation are relevant, since zeros are no longer utilized to set the decimal point.

When working with very big or very small numbers, scientists, mathematicians, and engineers employ scientific notation. Large and tiny numbers can be represented in a form that is simpler to read using exponential notation.

Thus, option D is correct.

Taking into account the reaction stoichiometry, 1 mol of KCl is formed from 119 grams of KBr.

In first place, the balanced reaction is:

Cl₂ + 2 KBr → 2 KCI + Br₂

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

The molar mass of the compounds is:

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

The following rule of three can be applied: if by reaction stoichiometry 238 grams of KBr form 2 moles of KCl, 119 grams of KBr form how many moles of KCl?

[tex]moles of KCl=\frac{119 grams of KBrx2 moles of KCl}{238 grams of KBr}[/tex]

moles of KCl= 1 mole

Then, 1 mol of KCl is formed from 119 grams of KBr.
