Answer:

A. We still feel gravity because of inertia, which occurs all around us. Gravity is not felt as much because although it feels small, gravity is the attraction that keeps objects on Earth.

B. This is due to a field and a law, which states that opposites attract and like repel.

Ammonia (NH3) can be produced by the reaction of hydrogen gas with nitrogen gas:
VARVARA [1.3K]

Answer:

Percent yield = 61.5%

Explanation:

Given data:

Moles of hydrogen = 2.00 mol

Actual yield of ammonia= 0.80 mol

Percent yield = ?

Solution:

Chemical equation:

3H₂ + N₂ → 2NH₃

Now we will compare the moles of ammonia with hydrogen from balance chemical equation:

                     H₂       :       NH₃

                      3        :         2

                      2        :       2/3×2 = 1.3 mol

Percent yield:

Percent yield = Actual yield / theoretical yield × 100

Percent yield = 0.80 mol /1.3 mol × 100

Percent yield = 0.615 × 100

Percent yield = 61.5%

A student placed 19.0 g of glucose (c6h12o6) in a volumetric flask, added enough water to dissolve the glucose by swirling, then
EleoNora [17]
  <span>moles glucose = 19 g / 180 g/mol= 0.105 
M = 0.105 / 0.100 L = 1.05 

moles in 20.0 mL = 1.05 M x 0.0200 L = 0.0216 

New concentration = 0.0216 /0.500 L = 0.0432 M 
moles in 100 mL = 0.100 L x 0.0432 = 0.00432 

mass = 0.00432 x 180 g/mol= 0.778 g</span>

Which represents the ionization of a strong electrolyte?
olga55 [171]
The answer is K3PO4(s) → 3K+(aq) + PO43–(aq) since water-soluble ionic tripotassium phosphate dissociates completely into K+ and PO43– ions when dissolved, that is, no K3PO4 remains in the solution. Carbonic acid H2CO3 and acetic acid CH3COOH are weak electrolytes since they are weak acids that do not completely ionize, while nonelectrolyte CH3OH do not dissociate into ions.
