Answer:
It is based on testable and replicable evidence.
Answer: The rate constant for the reaction is
Explanation:
Expression for rate law for first order kinetics is given by:
where,
k = rate constant
t = age of sample = 559 min
a = let initial amount of the reactant =
a - x = amount left after decay process =
The rate constant for the reaction is
Answer: 631.8 g
Explanation:
It can be seen from the balanced chemical equation, 2 moles of ethane reacts with 7 moles of Oxygen gas to produce 4 moles of carbon dioxide and 6 moles of water.
Ethane is the limiting reagent as it limits the formation of product.
Thus, if 2 moles of ethane produce 6 moles of water.
11.7 moles moles of ethane produce=of water.
Mass of water= no of moles Molar mass
Mass of water= 35.1 18g/mol= 631.8 g
Metals are shiny because of their electrons. These electrons produce light when they come in contact with light. I hope this helps.
