Explanation: You're welcome and can you pls give me the brainiest
Answer:
I cant answer B, but I can answer A, and I don't think it is a scientifically reasonable plan.
Explanation:
The bag of sand weighs less than the gold statue, and yes the bag of sand seems like it would keep the trap from activating, but you would scientifically have to put something that was the same weight as the gold statue on the pedestal that the statue is on.
The balanced equation:
2 H₂ + O₂ → 2 H₂O
moles of Hydrogen = mass of hydrogen ÷ molar mass of hydrogen
= 45.7 g ÷ 2 g/mol
= 22.85 mol
Now, the mole ratio of O₂ : H₂ is 1 : 2
which means that there are two times as much moles of H₂ as O₂ taking
part in the reaction
Thus since moles of H₂ = 22.85 mol
then moles of O₂ = 22.85 ÷ 2 = 11.425 mol
Mass of O₂ = moles of O₂ × molar mass of O₂
= 11.425 mol × 32 g/mol
= 365.6 g
∴ <span>grams of oxygen are needed to react with 45.7 grams of hydrogen is 365.6g</span>
<h2><u>Answer:</u></h2>
It wasn't an adjustment in the condition of issue on the grounds that the vitality in the can did not change. Additionally, since this was a physical change, the atoms in the can are as yet similar particles. No synthetic bonds were made or broken. You added enough vitality to make a stage change from strong to fluid.
The main changes recorded which don't include framing or breaking substance bonds would bubble and liquefying. Bubbling and liquefying are physical changes as opposed to synthetic changes, so no new items are shaped.
Salt is a mixture,salt is composed of sodium and chlorine,NaCI.Its a compound of two distinct elements that can not be broken down further without changing the properties of the substance.(I hoped that helped)
