Answer:
Noble gases
Explanation:
Noble gases are nonreactive, nonmetallic elements in group 18 of the periodic table. As you can see in the periodic table in the figure below, noble gases include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).18 Jun 2021
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.
Answer:
A skateboarder coming down the ramp.
When something is going up against ( up or <u><em>down</em></u> ) something it causes friction.
Hope this helps!
Because the easier a metal donates an electron (Low Ionization Energy), the more readily a non-metal with high electromagnetically will accept it.
Thus they match well, - one readily donates, the other readily accepts. This is how ionic bonding occurs.
Hope this helps.
Answer:
The Kc of this reaction is 311.97
Explanation:
Step 1: Data given
Kp = 0.174
Temperature = 243 °C
Step 2: The balanced equation
N2(g) + 3H2(g) ⇌ 2NH3(g)
Step 3: Calculate Kc
Kp = Kc *(RT)^Δn
⇒ with Kp = 0.174
⇒ with Kc = TO BE DETERMINED
⇒ with R = the gas constant = 0.08206 Latm/Kmol
⇒ with T = the temperature = 243 °C = 516 K
⇒ with Δn = number of moles products - moles reactants 2 – (1 + 3) = -2
0.174 = Kc (0.08206*516)^-2
Kc = 311.97
The Kc of this reaction is 311.97
