Answer:
652.6 g of H₃PO₄ are formed
Explanation:
Reaction is:
P₄O₁₀(s) + 6H₂O(l) → 4H₃PO₄(aq)
As P₄O₁₀ is the reactant in excess, the limiting is water.
Ratio is 6:4. We make a rule of three:
6 moles of water produce 4 moles of phosphoric acid
Therefore, 10 moles of water may prodyce (10 .4) / 6 = 6.66 moles of H₃PO₄
We convert the moles to mass:
6.66 moles . 97.9 g / 1mol = 652.6 g
Answer:
The general formula for an acid is HnX where H stands for hydrogen, n stands for the number of hydrogen ions, and X stands for the monatomic or polyatomic ions ( since those are negative charged ions, they are called anions).
Explanation:
The general formula for an acid is HnX) where H stands for hydrogen, n stands for the number of hydrogen ions, and X stands for the monatomic or polyatomic ions ( since those are negative charged ions, they are called anions).
An example is H2SO4, also called sulfuric acid
It shows that H2SO4 has 2 hydrogen atoms, so in the formula HnX n=2
X fro H2SO4 is SO42-, it's a polyatomic ion. Since it has a negative charge of 2- it needs 2 hydrogen atoms to bind and form H2SO4
That’s wrong it is a physical change. And that is because only the states are being changed. No bonds are broken or made during this inside the actual compound.
Answer: <em>True</em>
Explanation:
<em>Venus is the hottest planet in the solar system. Mercury is still hot but half of it is also cold due to the sun not directly pointing at it.</em>

Mineral water is a type of mixture called a homogeneous solution. This is because there are very small amounts of dissolved minerals in mineral water, such as zinc, iron, copper, magnesium and many others. However, to the eye, mineral water just looks like distilled water.
