A pH of 1 there are a lot of ______ in a solution. 2.A pH of 14 there are a lot of ______ in a solution.

Answers

Answer:

Hydrogen or hydroxonium ions in the solution

Hydroxyl ions in the solution

Explanation:

A pH of 1 shows there is a lot of hydroxonium ions in the solution and a pH of 14 shows there is a lot of hydroxyl ions in the solution.

The pH scale ranges from 1 to 14 As the values tends towards 1, the acidity increases due to concentration of hydroxonium ions in the solution. As the pH tends towards 14, the basicity increases due to the concentration of hydrogen ions in the solution.

What’s the difference between a learned behavior in an inherited behavior? Give one example of each

Answers

Answer:

short answers:

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.

What is learned behaviour?

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:

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

Reaction stoichiometry

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:

Cl₂: 1 mole KBr: 2 molesKCI: 2 molesBr₂: 1 mole

The molar mass of the compounds is:

Cl₂: 70.9 g/moleKBr: 119 g/moleKCI: 74.55 g/moleBr₂: 159.8 g/mole

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

Cl₂: 1 mole ×70.9 g/mole= 70.9 gramsKBr: 2 moles ×119 g/mole= 238 gramsKCI: 2 moles ×74.55 g/mole= 149.1 gramsBr₂: 1 mole ×159.8 g/mole= 159.8 grams

Moles of potassium chloride produced

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.

What is the charge of phosphate in AlPO4?

Answers

The charge of phosphate : 3-

Further explanation

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

Explain why, in a balanced chemical equation C + O2 CO2, we know that 1 gram of C will not react exactly with 1 gram of O2.

Answers

Answer:

See the answer below

Explanation:

From the equation, 1 mole of C requires 1 mole of O2 for a balanced reaction.

1 g of C will not exactly react with 1 g of O2 because the 1 g of each of the reactants contain different amounts of the substance.

The amount (in moles) of a substance is the mass of that substance divided by the molar mass.

Hence, 1 g of C will contain 1/12 moles of the substance while 1 g of O2 will contain 1/32 moles of the substance.

calculate the percentage of iron in iron (III) sulphate

Answers

Answer:

28.01 percent

Explanation:

Iron (III) sulphate, [tex]Fe_2(SO_4)_3[/tex], has 2 atoms of Fe.

One atom of Fe has a molar weight of 56. Hence, 2 atoms of Fe would have a total molar weight of 56 x 2 = 112 g/mol

Molar weight of  [tex]Fe_2(SO_4)_3[/tex] = 399.88 g/mol

Percentage Fe in [tex]Fe_2(SO_4)_3[/tex] = 112/399.88 x 100%

                       = 28.01%

The percentage of iron is iron (III) sulphate is, therefore, 28.01 percent.

If a 200 kg person stands next to a 100 kg person. Which person would have a larger gravitational attraction?

Answers

Answer:

200 kg

Explanation:

the 200 kg person is heavier due to gravity's force the 100 kg person has less force than the other person

Answer:

massive one that is 200kg

Explanation:

Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.
