The correct answer is compound.  

The compounds comprise two or more elements, which are bonded together chemically, and can be dissociated, that is, distinguished by reforming and breaking the chemical bonds, by the decomposition reactions, like thermal decomposition or electrolysis. The process of decomposition generate simpler compounds or individual elements.

What is the net ionic equation of the reaction of mgso4 with sr(no3)2?
Bad White [126]

Balanced chemical reaction:  

MgSO₄(aq) + Sr(NO₃)₂(aq) → Mg(NO₃)₂(aq) + SrSO₄(s).

Ionic reaction:  

Mg²⁺(aq) + SO₄²⁻(aq) + Sr²⁺(aq) + 2NO₃⁻(aq) → Mg²⁺(aq) + 2NO₃⁻(aq) + SrSO₄(s).

Net ionic reaction:

Sr²⁺(aq) + SO₄²⁻(aq) → SrSO₄(s).

Magnesium sulfate (MgSO₄), strontium nitrate (Sr(NO₃)₂ and magnesium nitrate (Mg(NO₃)₂) are soluble in water. Strontium sulfate (SrSO₄) is not soluble in water.

This chemical reaction is double displacement reaction - cations and anions of the two reactants switch places and form two new compounds.

Can someone please help with this I need the answers for the three boxes
denis23 [38]

Answer:

Type: M

Name: Dixytrogen Pentasulfide

Molar Mass:

X*2 = Number * 2 = Number

S*5=32.066*5=160.33

Number + 160.33 = Molar Mass (g/mol).

(The mass for Xytrogen is not present).

Explanation:

Assuming Xytrogen is a non-metal and bonding it with sulfur, another non-metal would make it covalent or molecular.  

The name is from the amount of Xs (being two [Di]) and the amount of Ss (being five [Penta]).

The molar mass is explained above.  You need to multiply the mass of each element by the number of elements present in the compound.  The mass for Xytrogen is not present (as it is a made up element) so I left instructions how to do it once given the mass instruction.

Hope this helps.
