A 3.0 L balloon is 2.5 times as big as a 1.2L balloon, and 3 times .060 equals .18, so if you multiply .18 by 2.5 you get .45 moles of air i’m pretty sure
P₄0₆
+ 20₂
⇒ P₄0₁₀![_{s}](https://tex.z-dn.net/?f=_%7Bs%7D)
Explanation:
The overall equation for the reaction that produces P₄0₁₀ is :
P₄0₆
+ 20₂
⇒ P₄0₁₀![_{s}](https://tex.z-dn.net/?f=_%7Bs%7D)
Now let us derive this equation:
Given equations:
P₄
+ 30₂
⇒ P₄0₆
equation 1;
P₄
+ 50₂
⇒ P₄0₁₀
equation 2;
To get the overall combined equation, the equation 1 must be reversed and added to equation 2:
P₄0₆
⇒ P₄
+ 30₂
equation 3
+
equation 2:
P₄
+ 50₂
+ P₄0₆
⇒ P₄0₁₀
+ P₄
+ 30₂
cancelling specie that appears on both sides and removing excess oxygen gas on the reactant side gives;
P₄0₆
+ 20₂
⇒ P₄0₁₀![_{s}](https://tex.z-dn.net/?f=_%7Bs%7D)

Only the first word in an organism's complete scientific name has its first letter capitalized.
When writing out the organism's scientific name, it goes Genus and then species. The Genus is always capitalized and species is always lowercase. Also when writing the name, usually you either write it in italics or underline the scientific name.
Answer:
Nichrome
Answer: Hot water system coils are commonly made up of metal alloys which are a combination of two or more elements. The most commonly used metal alloy is “Nichrome”. Nichrome is an alloy of nickel (80%) and chromium (20%).
The grams of aluminium extracted from 5000g of alumina is 2647 grams
<h3>Chemical formula of alumina:</h3>
Let's calculate the molecular mass of Al₂O₃
Al₂O₃ = 27 × 2 + 16 × 3 = 54 + 48 = 102 g/mol
Therefore,
102 g of Al₂O₃ = 54 g of aluminium
5000g of Al₂O₃ = ?
mass of aluminium produced = 5000 × 54 / 102
mass of aluminium produced = 270000 / 102
mass of aluminium produced = 2647.05882353
mass of aluminium produced = 2647 grams
