Answer: false
Explanation: Reason being A substance cannot be a gas or a mixture, only can a pure substance that occurs in nature may
Answer:
(C) substance B is not involved in the rate-determining step of the mechanism but is involved in subsequent steps.
Explanation:
A. Is incorrect because if the order of the reaction with respect B was one then the rate would increase by the same multiple that B is increased by.
B. If B is reactant then it must be involved in the mechanism of the reaction and in the formation of the product
D. If B was a catalyst then increasing it's amount would affect the rate
E. That is just factually untrue. Effect of reactants on rates can only be found experimentally, not stoichiometrically.
Answer:
0
Explanation:
To calculate, the mass of Carbondioxide is 3.45mg
Then the decomposition of Carbondioxide gives 0 on calculation
Cobalt-59 and Cobalt-60 differ in that they have different mass number which means they have different number of neutrons. Isotopes are atoms of the same element with similar atomic number but different mass number. Cobalt-60, has a number of uses, which includes, being used to irradiate food sources as a method of preserving food, used in industrial radiography to detect structural flaws in metal parts among other uses.
Answer:
4.63 moles of CCl4
Explanation:
C + 2Cl2 = CCl4
The balanced equation tells us that we'll obtain 1 mole of CCl4 for every 1 mole of C, assuming we have 2 or more moles of Cl2 (which we do in this problem).
Therefore, if we start with 4.63 moles of C, we'll produce 4.63 moles of CCl4
