Answer:

2Mg + O2 → 2MgO

Explanation:

Step 1: Data given

Magnesium = Mg

Oxygen = O2

magnesiumoxide = MgO

Step 2: The unbalanced equation

Mg + O2 → MgO

Step 3: Balancing the equation

On the left we have 2x O so on there right, we should mulitply MgO by 2 so we have on each side 2x O

Mg + O2 → 2MgO

On hte right side we have 2x Mg, so we have to multiply on the left side Mg by 2 to have the same amount of Mg on both sides

2Mg + O2 → 2MgO

Now the equation is balanced

why do you think you can find silver and gold on their own in rocks but calcium and magnesium are combined with other elements t
katrin [286]

Explanation:

Silver and Gold belong to a special group of metals known as the native metals. They are found naturally on their own and not in combined form in rocks.

  • These metals are found uncombined because they are unreactive.
  • They prefer to alloy with themselves.
  • Calcium and magnesium on the other hand are reactive metals.
  • The unreactivity of these metals makes them uncombined in nature.

When 4.41g of phosphoric acid (H3PO4) react with 9.25g of barium hydroxide, water and insoluble barium phosphate form. [T/I-7] a
AnnZ [28]

Answer:

2 H₃PO₄(aq) + 3 Ba(OH)₂(aq) ⇒ Ba₃(PO₄)₂(s) + 6 H₂O(l)

Explanation:

Let's consider the unbalanced equation that occurs when phosphoric acid reacts with barium hydroxide to form water and barium phosphate. This is a neutralization reaction.

H₃PO₄(aq) + Ba(OH)₂(aq) ⇒ Ba₃(PO₄)₂(s) + H₂O(l)

We will balance it using the trial and error method.

First, we will balance Ba atoms by multiplying Ba(OH)₂ by 3 and P atoms by multiplying H₃PO₄ by 2.

2 H₃PO₄(aq) + 3 Ba(OH)₂(aq) ⇒ Ba₃(PO₄)₂(s) + H₂O(l)

Finally, we will get the balanced equation by multiplying H₂O by 6.

2 H₃PO₄(aq) + 3 Ba(OH)₂(aq) ⇒ Ba₃(PO₄)₂(s) + 6 H₂O(l)
