35.0 grams of nitrogen gas reacts with 60.0 grams of hydrogen gas: N2 + 3H2--> 2NH3
Misha Larkins [42]

Explanation:

Moles of N2 = 35.0g / (28g/mol) = 1.25mol

Moles of H2 = 60.0g / (2g/mol) = 30.0mol

Since 1.25mol * 3 < 30.0mol, nitrogen is limiting.

Moles of NH3 = 1.25mol * 2 = 2.50mol.

Mass of NH3 = 2.50mol * (17g/mol) = 42.5g.

30.0mol - 1.25mol * 3 = 26.25mol.

Excess mass of H2

= 26.25mol * (2g/mol) = 52.5g.

marshall27 [118]

38 ATP molecules are present in one molecule of glucose.

<u>Explanation:</u>

Cellular respiration can be separated into 5 stages, and every one of them - with the exception of the first - happen inside mitochondria. Changes  1 molecule of glucose into 2 particles of pyruate.

Biology textbooks often state that 38 ATP molecules can be made per oxidized glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).

Classify these compounds by whether they behave as strong acids, weak acids, strong bases, or weak bases in aqueous solution.
zaharov [31]

Answer:

HI& HNO3= strong acid

H2CO3 &HF= weak acid

LiOH & Ba(OH)2= strong base

CH3NH2= weak base

NH4Cl = weak acid solution

Na3PO4 = weak base solution

Explanation:

HI& HNO3= strong acid because they can dissociate completely producing free Oxonium ions

H2CO3 &HF= weak acid because there dissociate partly in Solution

LiOH & Ba(OH)2= strong base because LiOH is a group one alkali which dissociate completely and Ba(OH)2 a group 2 alkali which dissociate completely as well

CH3NH2= weak base because in solution it dissociates partly forming NH4+ ion

NH4Cl = weak acid solution because it is a salt of strong acid and weak base

Na3PO4 = weak base solution

Because it's a salt of strong base and weak acid
