Answer:
backward, opposite, retrograde
Explanation:
why, i just got it right when i put that.
Answer:
metal atom
Explanation:
metallic solid has layers makes it soft and it also has electron that can carry charge and conduct electricity.
The equation is L = m/M
First, covert 10. grams of AgNO3 to moles which is 0.059 moles.
Divide 0.059 moles by 0.25M which is 0.24 liters.
Answer:
The answer to the question is;
The equilibrium constant for the reaction is 0.278
Reversibility.
Explanation:
Initial concentration = 0.500 M N₂ and 0.800 M H₂
N₂ (g) + 3·H₂ (g) ⇔ 2·NH₃ (g)
One mole of nitrogen combines with three moles of hydrogen form 2 moles of ammonia
That is 1 mole of ammonia requires 3/2 moles of H₂ and 1/2 moles of N₂
0.150 M of ammonia requires 3/2×0.150 moles of H₂ and 1/2×0.150 moles of N₂
That is 0.150 M of ammonia requires 0.225 moles of H₂ and 0.075 moles of N₂
Therefore at equilibrium we have
Number of moles of Nitrogen = 0.500 M - 0.075 M = 0.425 M
Number of moles of Hydrogen = 0.800 M - 0.225 M = 0.575 M
Number of moles of Ammonia = 0.150 M
K
=
= 0.278
The kind of reaction is a reversible one as the equilibrium constant is greater than 0.01 which as general guide, all components in a reaction with an equilibrium constant between the ranges of 0.01 and 100 will be present when equilibrium is reached and the chemical reaction will be reversible.
Answer:
The answer to your question is 1.013 Kg
Explanation:
TiCl₄ + 2Mg ⇒ 2MgCl₂ + Ti
mass of Mg = ?
mass of Ti = 1 kg
Process
1.- Calculate the molar mass of Magnesium and titanium (IV)
Mg = 24.3 g x 2 = 48.6 g
Ti = 48 g
2.- Write a proportion (rule of three)
48.6 g of Mg ------------- 48 g of Ti
x ------------- 1000 g of Ti
x = (1000 x 48.6) / 48
3.- Result
mass of Magnesium = 1012.5g
= 1.013 kg
