4 0

Explanation:

Given;

  Number of moles of the elements = 3.8moles

Molar mass of Gold  = 196.966g/mol

Molar mass of Magnesium  = 24.3g/mol

Molar mass of Tin  = 118.710g/mol

Molar mass of Bromine  = 79.904g/mol

   Mass  = number of moles x molar mass

Mass of Gold = 3.8 x 196.966  = 748.5g

 Mass of Magnesium  = 3.8 x 24.3  = 92.3g

Mass of Tin  = 3.8 x 118.710  = 451.1g

Mass of Bromine  = 3.8 x 79.904  = 303.6g

consider an atom having four distinct neergy levels. if an electron is able to make transitions between, any two levels, how man
ludmilkaskok [199]

Answer:

6 different frequencies

Explanation:

From energy level 1 to 2 is one frequency, from energy level 1 to 3 is one frequency and From energy level 1 to 4 is one frequency. So, we have a total of 3 frequencies for transition from energy level 1.

From energy level 2 to 3 is one frequency and from energy level 2 to 4 is one frequency. So, we have a total of 2 frequencies for transition from energy level 2.

From energy level 3 to 4 is one frequency.

So we have a total of 3 + 2 + 1 different frequencies = 6 different frequencies.

Note that the reverse process for each step produces the same frequency as the step in consideration.

Predict the products and write the balanced chemical equation for this reaction. Include the physical state of the product(s).
sukhopar [10]

Answer:

Al(C2H3O2)3 (aq) + 3AgNO3 (aq) ------>Al(NO3)3(aq) + 3Ag(C2H3O2)(s)

Explanation:

A chemical reaction refers to an interaction between two or more chemical species that leads to the formation of other new chemical species.

There are many types of chemical reactions. The type shown above is called a double replacement reaction. In this type of reaction, ions exchange partners in the product.

A chemical reaction is said to be balanced when the number of atoms of each element on the left hand and right hand sides of the reaction equation are exactly the same.
