(no 'A')
Answers
The answer option which is an incorrect orbital notation is: C. 2d.
A sublevel refers to an energy level that is typically associated with the valence electrons found outside an atomic nucleus.
In Chemistry, there are four (4) main types of sublevel and these includes:
s orbital (sublevel): 3sp orbital (sublevel): 2pd orbital (sublevel): 3df orbital (sublevel): 4fHowever, it is impossible for any atom of a chemical element to have a 2d orbital because electrons are generally located in the s and p orbitals (sublevels) in the second energy level.

A. Calculating the molar mass of the ending compound.If 20 hits equal 1 web 1 futz equal 2 geese 10 webs equal to 1 futz How many gits are equal to 5gews?
Answers
Answer:
500 hits
Explanation:
If 20 hits equal 1 web 1 futz equal 2 geese 10 webs equal to 1 futz How many hits are equal to 5 geese?
Solution:
Given that:
20 hits = 1 web, 1 futz = 2 geese; 10 webs = 1 futz
10 webs = 1 futz; hence:
1 web = 1 web * 1 futz / 10 webs = 0.1 futz
1 web = 0.1 futz
1 futz = 2 geese; hence:
0.1 futz = 0.1 futz * 2 geese / 1 futz
0.1 futz = 0.2 geese
Therefore, 1 web = 0.1 futz = 0.2 geese
1 web = 0.2 geese
This means that 20 hits = 1 web = 0.2 geese
20 hits = 0.2 geese
5 geese = 5 geese * 20 hits / 0.2 geese
5 geese = 500 hits

Balance the chemical equation. Based on the equation, how many grams of bromine are produced by the complete reaction of 11 grams of potassium bromide? Use the periodic table to get the weights of the elements. Carry out your calcuation in the same way as you did in parts A, B, and C. That is, begin by converting grams of KBr to moles of KBr, then use the mole ratio of KBr to Br2.
Answers
Answer:
Explanation:
The balanced chemical equation is Cl2 + 2KBr → 2KCl + Br2. The amount of bromine is calculated as follows:
11.0 g KBr (1mol KBr/119.002g KBr * 1mol Br2/2mol KBr * 159.808g Br2/1mol Br2= 7.39 g Br2.)
The balanced chemical equation is Cl₂ + 2 KBr → 2 KCl + Br₂.7.39 g of bromine are produced by the complete reaction of 11 grams of potassium bromide.
What is chemical equation?The Chemical equation is a symbolic representation of a chemical reaction is written in form of symbols and chemical formulas.The reactants are present on the left hand side while the products are written on the right hand side of the chemical equation.
A plus sign is written between reactants and products if they are more than one reactants or products in any case and an arrow is present which points towards the product side which indicates the direction of the reaction in which it is proceeding.There are coefficients present next to the chemical symbols and formulas .
The balanced chemical equation is Cl2 + 2KBr → 2KCl + Br2. The amount of bromine is calculated as follows:
11.0 g KBr which is 1 mole of KBr/119.002 g KBr × 1 mole of Br₂/2 mole KBr × 159.808 g Br₂/1 mole of Br₂= 7.39 g Br₂.

is mending a broken bone chemical change and why(short answer pls)
Answers
Answer:
In a physical change, the substances involved retain their original properties. A new substance is not formed. A physical change can be reversed. Chemical changes happen on a molecular level when two or more substances chemically bond together.
Mending a broken bone is a chemical change as to heal the bone enzymes are released which are chemicals.
What is a chemical change?Chemical changes are defined as changes which occur when a substance combines with another substance to form a new substance.Alternatively, when a substance breaks down or decomposes to give new substances it is also considered to be a chemical change.
There are several characteristics of chemical changes like change in color, change in state , change in odor and change in composition . During chemical change there is also formation of precipitate an insoluble mass of substance or even evolution of gases.
There are three types of chemical changes:
1) inorganic changes
2)organic changes
3) biochemical changes
During chemical changes atoms are rearranged and changes are accompanied by an energy change as new substances are formed.
