Answer:
The answer to your question is a) limiting reactant SO₂
b)mass of SO₃ produced 31.25 g
Explanation:
Data
mass of SO₂ = 25 g
mass of O₂ = 40 g
Balanced Reaction
2SO₂ + O₂ ⇒ 2SO₃
Process
1.- Calculate the molecular mass of the reactants
SO₂ = 32 + (16 x 2) = 32 + 32 = 64
O₂ = 16 x 2 =32
2.- Use proportions to determine the limiting reactant
Theoretical proportion 2(SO₂) / O₂ = 2(64) / 32 = 4
Experimental proportion SO₂ / O₂ = 25 / 40 = 0.625
From these results, we determined that the limiting reactant is SO₂, because the proportion in the experiment is lower.
3.- Amount of SO₃ produced
Mass of SO₃ = 32 + (3 x 16) = 80 g
128 g of SO₂ --------------- 2(80) g of SO₃
25 g of SO₂ --------------- x
x = (25 x 2 x 80) / 128
x = 31.25 g of SO₃
Answer:
(c.) as the force of Earth's gravity on an object increases, the object's mass increases
Explanation:
Based on newton's law of gravitation "every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of the masses of the particles and inversely proportional to the square of the distance between them".
It is mathematically expressed as:
F = 
F is the gravitational force on either particle
m₁ and m₂ are the masses
r is the distance between particles
G is the universal gravitation constant.
From this expression, we see that the force of earth's gravity is directly proportional to mass.
Answer:
C.
Explanation:
Butane (C4H10) has 3 C-C bonds in the carbon chain and 10 C-H bonds
Answer:
according to my reading
use own words
Explanation:
Salts are combinations of acids and bases. The cation comes from a base and the anion from an acid. Therefore, to make KNO3 we react KOH and HNO3. See how that is done? We write K and add OH to make KOH. We take NO3 and add H to make HNO3.
