Answer:
solo I
Explanation:
Según esta teoría para que se produzca una reacción deben cumplirse tres condiciones: Las moléculas de los reactivos tienen que chocar entre sí. Estos choques deben de producirse con energía suficiente de forma que se puedan romper y formar enlaces químicos.
Answer:
Pangaea
Explanation:
About 300 Million Years Ago, Earth Didn't Have Seven Continents But Instead Earth Had One Massive Super continent Called Pangaea.
Answer: Option A
Explanation:
Increase in temperature will increase the yield of the product and cause a shift to the right.
<h2>
What is an Endothermic reaction?</h2>
This is the type of reaction in which reactants absorb heat energy from the surroundings to form products.
This depicts that an increase in temperature will increase the yield of products thereby making option A the most appropriate choice.
Answer:
Mass of methane required in gram = 226.35 gram (Approx.)
Explanation:
Given:
Heat energy used = 12,567 kJ
Missing data;
Δcombustion = 891 kJ/mol
Find:
Mass of methane required in gram
Computation:
Number of mol methane burned = Heat energy used / Δcombustion
Number of mol methane burned = 12,571 / 891
Number of mol methane burned = 14.1088 mol
1 mol of methane in gram = 16.043 grams
So,
Mass of methane required in gram = Number of mol methane burned x 1 mol of methane in gram
Mass of methane required in gram = 14.1088 x 16.043
Mass of methane required in gram = 226.3474
Mass of methane required in gram = 226.35 gram (Approx.)
Flourine
Explanation:
The element F has a high negative (ΔeqHө) but not so high IE1 . Therefore, it is the least reactive non-metal.
