Mass O2 = = 16.832 g
<h3>Further explanation</h3>
Given
43 grams of potassium chlorate
Required
Mass of O2
Solution
Reaction
2KClO3 ⇒3O2 + 2KCl
Mol KClO3 :
= mass : MW
= 43 g : 122,55 g/mol
= 0.3509
From the equation, mol O2 :
= 3/2 x moles KClO3
= 3/2 x 0.3509
= 0.526
Mass O2 :
= 0.526 x 32 g/mol
= 16.832 g
<span>1. False. Intrusive rock has coarser crystal formation.
2. True. They are typically extrusive if formed by lava, intrusive through magma.
3. False. The process of lithification in sediments produces sedimentary rock.
4. True. This process compacts and cements the grains together, often squeezing out water in the process.
6. Metamorphic rock. Often rock near an igneous inclusion will metamorphose if the heat is not enough to cause melting.
7. False. All rocks in the rock cycle can become the other type with the right processes.
8. False. The rock cycle is continuous with rocks constantly shifting from one stage to another.
9. False. Foliation only occurs in metamorphic rock, with gneiss serving as a prime example.</span>
Answer: B
Explanation: because it just makes sense
Answer:
How does the equilibrium change with the removal of hydrogen (H2) gas from this equation? 2H2S ⇌ 2H2(g) + S2(g) A. ... Equilibrium shifts left to produce less reactant.
Explanation:
option A is the correct answer
Equilibrium shifts right to produce more product.
I hope it will help you.
Explanation:
[H+]=10^-pH
[H+]=10^-9.2
[H+]=6.031x10^-10
[OH-]=1x10^-14÷[H+]
[OH-]=1x10^-14÷[6.031x10^-10]
[OH-]= 1.66x10^-5
im pretty sure this is right
