Answer:
5.97 mol
Explanation:
To find the number of moles when given the mass of a substance, we divide the mass of the sample by its molar mass.
so, we get,
nN203 = 454 g / 76.01 g /mol
= 5.97 mol
The overall order of a reaction is directly
related to the reaction mechanism of the reaction. The reaction mechanism is
defined by the reaction rate equation. In this case, we are given by the
equation, Rate=k. The order of this reaction is zero since the rate is
not dependent on the concentration of reactants or products.
Answer:
3) neutrons and protons
Explanation:
I just completed Grade 11 Chemistry with a 97% and I'm still under the impression that all atoms have only neutrons and protons in their nuclui.
I apologize if this is a question above my current education.
The compound may or may not be poisonous, depending on the chemical properties of the new substance.
Answer:
(A)explaining how Marx believed the goals of communism would fix the problems of capitalism.
Explanation:
In the section, "The Necessary Resources", after listing the four resources needed for an economic system to thrive, the author explained the practice of capitalism in the mid-1800s, where people owned private property and how Karl Marx and Friedrich Engels came up with the notion that capitalism did not allow for the fair distribution of resources.
In the section, "Karl Marx and Communism", further explanation was provided as to how Marx felt that capitalism caused a gap between the rich and the poor, how that system was unfair to poorly paid workers and how communism will soon replace capitalism.
