This is the number of protons and neutrons i the nucleus of any atom

icang [17]

Answer:

The mass number is defined as the total number of protons and neutrons in an atom. Consider Table below which shows data from the first six elements of the periodic table. Consider the element helium. Its atomic number is 2, so it has two protons in its nucleus.

When the following molecular equation is balanced using the smallest possible integer coefficients, the values of these coeffici

maxonik [38]

Answer:

1. Al2O3 + 3H2SO4 —> Al2(SO4)3 + 3H2O

The coefficients are: 1, 3, 1, 3

2. Yes, reaction occurs when ammonium carbonate and chromium(III) nitrate are combined.

The balanced equation for the reaction is given below:

3(NH4)2CO3 + 2Cr(NO3)3 —> 6NH4NO3 + Cr2(CO3)3

The coefficients are: 3, 2, 6, 1

Explanation:

1. The word equation is given below:

aluminum oxide(s) + sulfuric acid(aq) -> aluminum sulfate(aq) + water (l)

The above can be written as:

Al2O3 + H2SO4 —> Al2(SO4)3 + H2O

Now we can balance the equation as follow:

There are 3 atoms of SO4 on the right side and 1 atom on the left. It can be balance by putting 3 in front of H2SO4 as shown below:

Al2O3 + 3H2SO4 —> Al2(SO4)3 + H2O

There are 6 atoms of H on the left side and 2 atoms on the right. It can be balance by putting 3 in front of H2O as shown below:

Al2O3 + 3H2SO4 —> Al2(SO4)3 + 3H2O

Now the equation is balanced

The coefficients are: 1, 3, 1, 3

2. Yes, reaction occurs when ammonium carbonate and chromium(III) nitrate are combined.

The equation for the reaction is given below:

(NH4)2CO3 + Cr(NO3)3 —> NH4NO3 + Cr2(CO3)3

We can balance the equation above as follow:

There are 2 atoms of Cr on the right side and 1 atom on the left. It can be balance by putting 2 in front of Cr(NO3)3 as shown below:

(NH4)2CO3 + 2Cr(NO3)3 —> NH4NO3 + Cr2(CO3)3

Now, there are 6 atoms of NO3 on the left side and 1 on the right side. It can be balance by putting 6 in front of NH4NO3 as shown below:

(NH4)2CO3 + 2Cr(NO3)3 —> 6NH4NO3 + Cr2(CO3)3

Now, there are 2 atoms of NH4 on the left side and 6 atoms on the right. It can be balance by putting 3 in front of (NH4)2CO3 as shown below:

3(NH4)2CO3 + 2Cr(NO3)3 —> 6NH4NO3 + Cr2(CO3)3

Now the equation is balanced.

The coefficients are: 3, 2, 6, 1

What are all the possible masses of cl2 molecules that are made when two chlorine atoms bond together?

Pavel [41]

The masses of the 2 most common isotopes of Cl are 35 and 37. Therefore we can formulate 3 possible masses of Cl2:

35 + 35 = 70
35 + 37 = 72
37 + 37 = 74

However, Cl 35 is the most common isotope of chlorine of the two therefore it is the most probable that two Cl 35 atoms will combine, so 70 is the most common among all.

Lists how many valence electrons are shared, gained, or lost by each atom of the 6 compounds?

Blababa [14]

The number of electrons in an atom's outermost valence shell governs its bonding behavior.

In N₂, three electrons are being shared by each nitrogen atom, making a total of 6 shared electrons.

In CCl₄, 4 electrons are being shared by each carbon atom and 1 electron is being shared by each chlorine atom

In SiO₂, 4 electrons are being shared by each silicon atom and 2 electrons are being shared by each oxygen atom.

In AlCl₃, 3 electrons are being shared by each aluminum atom and 1 electron is being shared by each Cl atom

In CaCl₂, 2 electrons are lost by the calcium atom and 1 electron is gained by each chlorine atom

In LiBr, 1 electron is lost by the lithium atom and 1 electron is gained by the bromine atom
