After 7.9 grams of sodium are dropped into a bathtub full of water how many grams of hydrogen gas are released
Nataliya [291]

Answer:

<em>The grams of hydrogen gas that are released is 0.343 gram</em>

Explanation:

<em>Given that:</em>

<em>2 Na + 2h₂0 ⇒ 2Na0H +N₂</em>

<em>Molecules of Na = 7.9/2.3 = 0.343 mol Na</em>

<em>Now,</em>

<em>2 molecules  of Na produces one mole h₂</em>

<em>0.343 mol of Na produce  0.343/2 = 0.1717 mol h₂</em>

<em>h2 = molecules * mw (molecular weight)  =0.1717 * 2 =0.343 grams</em>

<em>Therefore the grams of hydrogen gas released is = 0.343 grams</em>

2. What are the characteristics of an acid (at least 3)?
arlik [135]

Answer:Acids taste sour, react with metals, react with carbonates, and turn blue litmus paper red. Bases taste bitter, feel slippery, do not react with carbonates and turn red litmus paper blue.

Explanation:

  • Sour taste (though you should never use this characteristic to identify an acid in the lab)
  • Reacts with a metal to form hydrogen gas.
  • Increases the H+ concentration in water.

Identify R and R' in Equation 1 when the ester, aspirin, is made from salicylic acid and acetic acid. (Equation 1) Calculate the
Flauer [41]

Answer:

in theoretical yield are obtained  2.61 g of aspirin from 2.0 g of salicylic acid and 5 mL of acetic anhydride

Explanation:

Aspirin (C9H8O4)

∴ mm C9H8O4 = 180 g/mol

salicylic acid (C7H6O3)

∴ mm C7H6O3 = 138 g/mol

acetic anhydride (C4H6O3)

∴ mm C4H6O3 = 102 g/mol

acetic acid (C2H4O2)

∴ mm C2H4O2 = 60 g/mol

reaction:

  • C7H6O3 + C4H6O3 → C9H8O4 + C2H4O2

∴ g C7H6O3 = 2.0 g

∴ g C4H6O3 = (5.0 mL)(1.08 g/mL) = 5.4 g

limit reagent (L.R):

∴ n C7H6O3 = (2 g)(mol/138 g) = 0.0145 mol C7H6O3 (L.R)

∴ n C4H6O3 = (5.4 g)(mol/102 g) = 0.053 mol C4H6O3 (E.R)

theoretical yield:

Amount of product predicted by balanced equation when all limit reagent reacts

⇒ n C9H8O4 = (0.0145 mol C7H6O3)(mol C9H8O4/mol C7H6O3) = 0.0145 mol C9H8O4

⇒ g C9H8O4 = (0.0145 mol)(180 g/mol) = 2.61 g C9H8O4
