Why can’t y’all do more points then 5? why can’t it be like 20-10
Answer:
d) additional heat alters the vicosity and the surface tension of the liquid which raises the vapor pressure and increases the boiling point which is why you must continually heat the solution
The inverted cone, hope it helps .
Answer:
second answer
Explanation:
The melting point would occur more quickly but stay the same.
So it is answer 2

Explanation:</h3>
<u>Step 1: Define</u>
[RxN] 4HCl (g) + 6NO (g) → 5N₂ (g) + 6H₂O (g)
[Given] 404.87 g HCl
<u>Step 2: Identify Conversions</u>
[RxN] 4 mol HCl = 5 mol N₂
Molar Mass of H - 1.01 g/mol
Molar Mass of Cl - 35.45 g/mol
Molar Mass of HCl - 1.01 + 35.45 = 36.46 g/mol
Molar Mass of N - 14.01 g/mol
Molar Mass of N₂ - 2(14.01) = 28.02 g/mol
<u>Step 3: Stoichiometry</u>
<u />
= 388.935 g N₂
<u>Step 4: Check</u>
<em>We are given 5 sig figs. Follow sig fig rules and round.</em>
388.935 g N₂ ≈ 388.94 g N₂
