Answer:
292.4 g
Explanation:
- 2Al + 3H₂SO₄ → 3H₂ + Al₂(SO₄)₃
First we <u>convert 53.7 g of Al into moles</u>, using its<em> molar mass</em>:
- 53.7 g ÷ 27 g/mol = 1.99 mol Al
Then we <u>convert Al moles into H₂SO₄ moles</u>, using the <em>stoichiometric coefficients</em>:
- 1.99 mol Al * = 2.98 mol H₂SO₄
Finally we <u>convert 2.98 moles of sulfuric acid into gram</u>s, using its <em>molar mass:</em>
- 2.98 mol H₂SO₄ * 98 g/mol = 292.4 g
Answer:
Option A
Explanation:
Emma creates a pressure difference allowing the fluid to flow
0.00000513467 would be the answer in standard form
So let’s say someone asks you what what element has an atomic mass of 190.23 in period 6 so it would be Osmium and the metals are Alkali Alkaline Earth Other metals transition metals inner transition metals lanthanoids actinides rare earth elements metalloids semimetals nonmetals halogens noble gases newly recognized elements those are how the elements are sorted the atomic number is how high or low something is like 43 61 84 through 118 is radioactive and atomic symbols like Pb stands for lead or Cr stands for Chromium so you should know how to use some parts of the periodic table this is all I know if you already knew this then I’m sorry
