Answer:
Wood
Explanation:
Matter is anything that has mass. Nor sound, fire or electricity have mass which leaves wood as the final answer.
Answer:
Answer is in the explanation.
Explanation:
For the reaction:
Ba₃(PO₄)₂(aq) + 3Na₂SO₄(aq) → 3BaSO₄(s) + 2Na₃PO₄(aq)
As Na₂SO₄(aq) is in excess, limiting reactant is Ba₃(PO₄)₂(aq). As the molarity of the solution is 0,25M and you knew the volume of the solution, you can obtain the moles of Ba₃(PO₄)₂ doing 0,25M×volume.
As 1 mol of Ba₃(PO₄)₂(aq) react with 3 moles of BaSO₄ the moles of BaSO₄ are three times moles of Ba₃(PO₄)₂.
As BaSO₄ molar mass is 233,38g/mol. The mass of BaSO₄ is given by moles of BaSO₄ × 233,38g/mol
I hope it helps!
Here is the three observation about copper.
<h3>What is copper?</h3>
copper (Cu), chemical element, a reddish, extremely ductile metal of the Group 11 (Ib) of the periodic table that is an unusually by its good conductor of to the electricity and heat. Copper of to the found in the free metallic state in nature. This is native copper was first by the used .
The reaction between to the copper carbonate and it is sulphuric acid will be a great neutralization reaction. Copper carbonate will acts like as a base, however, sulphuric acid is an acid. This reaction can also be the viewed as a double line displacement reaction too. By it's understand the nature of this reaction and what will be the final to product of this reaction.

Two substances that are tasteless are water and oxygen or air.
Answer:
Lewis structure of 
has been given below and formal charge of S is +2
Explanation:
- Lewis structure is drawn by placing least electronegative atom (except H) as central atom. Here S is least electronegative atom. Hence S is the central atom.
- Total valence electrons are calculated by adding valence electrons of all the constituting atoms. These electrons are used to make Lewis structure by fulfilling octet of all atoms and duet of hydrogen atoms.
- Total valence electron in is 24. Octet of S and two oxygen atoms should be fulfilled by using 18 electrons to draw Lewis structure.
- Formal charge on an atom = (no. of valence electrons)-(no. of covalent bonds)-(no. of electrons in lone pair/2)
- Lewis structure is given below
