Answer:
Chlorine gas.
Explanation:
Hello!
In this case, the undergoing chemical reaction is:
[tex]2Na+Cl_2\rightarrow 2NaCl[/tex]
Thus, given the moles of reacting both sodium and chlorine, we compute the moles of sodium chloride yielded by each reactant by considering the 2:2 and 1:2 mole ratios:
[tex]n_{NaCl}^{by\ Na}=6.70molNa*\frac{2molNaCl}{2molNa}=6.70molNaCl \\\\n_{NaCl}^{by\ Cl_2}=3.20molCl_2*\frac{2molNaCl}{1molCl_2}=6.40molNaCl[/tex]
Thus, since chlorine yields less moles of sodium chloride, we infer it is the limiting reactant.
Best regards!
The the balanced equations to: solutions of lithium sulfate and potassium phosphate are mixed together to make lithium phosphate and potassium sulfate
Answer:
[tex]3Li_2SO_4+2K_3PO_4\rightarrow 2Li_3PO_4+3K_2SO_4[/tex]
Explanation:
Hello!
In this case, when lithium sulfate and potassium phosphate solutions are mixed to yield lithium phosphate and potassium sulfate, the following chemical equation comes up:
[tex]Li_2SO_4+K_3PO_4\rightarrow Li_3PO_4+K_2SO_4[/tex]
However, as atoms are not balanced we apply the inspection method to obtain:
[tex]3Li_2SO_4+2K_3PO_4\rightarrow 2Li_3PO_4+3K_2SO_4[/tex]
Best regards!

Write the following elements in decreasing ionic size. Li+, C4+, F-, O2-
70 POINTS
Answer:
Li+, C4+, O2-, and then F- They're written in decreasing ionic size.
Explanation:
Ionic size means the same thing as ionic radius. Furthermore, Ionic radius is the distance away from the central atom. Ionic radius increases going from top to bottom and decreases across the periodic table.
Lithium is in the 1st family/group with a charge of +1. So it has the biggest ionic radius.
Carbon is in the 4th family/group with a charge of +4. So it has a smaller ionic radius than Lithium.
Oxygen is in the 6th family/group with a charge of -2. So it has a smaller ionic radius than Carbon.
Lastly, Fluorine is in the 7th family/group with a charge of -1. So it has a smaller ionic radius than Oxygen.
what is this element
Answer:
Oxygen
Explanation:
From the question given above, the following data were obtained:
Number of electrons = 8
Number of protons = 8
Number of Neutrons = 8
Name of element =?
Next, we shall determine the atomic number of the element. This can be obtained as follow:
The atomic number of an element is simply defined as the number of protons in the atom of the element. Mathematically, it is expressed as:
Atomic number = proton number
From the question given above,
Number of protons = 8
Therefore,
Atomic number = 8
Comparing the atomic number of the element (i.e 8) with those in the periodic table, we can conclude that the element is oxygen since no two elements have the same atomic number.
