<span>Harry Hess’s explained how oceanic crust is produced and destroyed in his theory of </span>D. Sea floor spreading
Answer:
1. Feature
2. Trait
Explanation:
I don't know how to explain why it's a feature, but number 2 is a trait because it makes you "you" (like blue eyes are different)
Answer:
200 grams of sodium hydroxide produce 595 grams of sodium sulfate if we have an excess of sulphuric acid
Explanation:
2 NaOH + H2SO4 → 2 H20 + Na S04
From the above chemical equation we can state that
2 moles of sodium hydroxide reacts with 1 mole of sulfuric acid to produce 1 mole of sodium sulfate.
Now if we start with 200 grams of sodium hydroxide and you have an excess of sulfuric acid then the amount in grams of sodium sulfate will be formed
2 moles of sodium hydroxide produce 1 mole of sodium sulfate.
In term of mass, we can say that
40 grams of sodium hydroxide produce 119grams of sodium sulfate
1 grams of sodium hydroxide produce (119/40) grams of sodium sulfate
then 200 grams of sodium hydroxide produce ((119*200)/40) grams of sodium sulfate
or 200 grams of sodium hydroxide produce 595 grams of sodium sulfate
Answer: The 1st Option. ( 159.7g) On EDG.
Explanation:
Answer: second option: mole ratio.
Explanation:
The coefficients of the chemical equation, when balanced, indicate the number ratio in which compounds combine with each other.
In the given equation, <span>Mg+2HCl -->MgCl₂+H₂
1 mole of Mg combines with 2 moles of HCl and produce 1 mole of MgCl₂ and 1 mol of H2.
So, the mole ratio is
1 mol Mg : 2 mol HCl : 1 mol MgCl₂ : 1 mol H₂.
In general, in a balanced equation of the kind aA + bB → cC + dD
The mole ratio is:
a mol of A : b mol of B : c mol of C : d mol D.
