Sodium and chlorine react to form sodium chloride. 2 na (s) + cl2 (g) → 2 nacl (s) what is the theoretical yield of sodium chlor
frosja888 [35]

Convert the given masses to moles.

• (55.0 g Na) (1/22.989 mol/g) ≈ 2.39 mol Na

• (67.2 g Cl₂) (1/70.9 mol/g) ≈ 0.948 mol Cl₂

The reaction consumes a ratio of 2 mol Na to 1 mol Cl₂, which means 0.948 mol Cl₂ reacts with 2 × 0.948 ≈ 1.90 mol Na, leaving an excess of about 0.494 mol Na.

The amount of NaCl produced is the same as the amount of Na consumed, so we end up with about 1.90 mol NaCl, which has a mass of about

(1.90 mol NaCl) (58.44 g/mol) ≈ 111 g NaCl

I need an essay about this
WARRIOR [948]

Answer:

The Interstate Highway System was launched when President Dwight D. Eisenhower signed the Federal-Aid Highway Act of 1956. Its purpose was to provide high-speed, high-capacity system of highways without stoplights and with exits spaced, whenever possible, at least a mile apart.

The interstate highway system has had a profound effect upon the American economy and contributed significantly to improved economic efficiency and productivity. By increasing speed and expanding access, freight costs have been reduced substantially.

They were intended to serve several purposes: eliminate traffic congestion; replace what one highway advocate called “undesirable slum areas” with pristine ribbons of concrete; make coast-to-coast transportation more efficient; and make it easy to get out of big cities in case of an atomic attack.May 27, 2010
