Answer:
Rate law is: Rate = k[NO2]^2 = 10 x [NO2]^2
When [NO2] = 0.200 M:
Rate = 10 x 0.200^2 = 0.400 M/s
When [NO2] = 0.100 M:
Rate = 10 x 0.100^2 = 0.100 M/s
When [NO2] = 0.050 M:
Rate = 10 x 0.050^2 = 0.0250 M/s
Explanation:
If you used the method of initial rates to obtain the order for no2, predict what reaction rates you would measure in the beginning of the reaction for initial concentrations of 0.200 m, 0.100 m, & 0.050 m no2.
Rate law is: Rate = k[NO2]^2 = 10 x [NO2]^2
When [NO2] = 0.200 M:
Rate = 10 x 0.200^2 = 0.400 M/s
When [NO2] = 0.100 M:
Rate = 10 x 0.100^2 = 0.100 M/s
When [NO2] = 0.050 M:
Rate = 10 x 0.050^2 = 0.0250 M/s
Under acidic conditions, the solution is red, and under alkaline conditions, the solution is blue. Chemical reactions other than acid-base can also cause a color change to litmus paper. For instance, chlorine gas turns blue litmus paper white – the litmus dye is bleached, because of presence of hypochlorite ions.
Answer:
with the molecular formula C3H5(ONO2)3, has a high nitrogen content (18.5 percent) and contains sufficient oxygen atoms to oxidize the carbon and hydrogen atoms while nitrogen is being liberated, so that it is one of the most powerful explosives known.
Explanation:
NTG reduces preload via venous dilation, and achieves modest afterload reduction via arterial dilation. These effects result in decreased myocardial oxygen demand. In addition, NTG induces coronary vasodilation, thereby increasing oxygen delivery.
A) Double replacement
Because the reactants switch when they become products
The best and most correct answer among the choices provided by the question is the second choice.
Carbon can easily bond with other atoms because it is an organic element.
I hope my answer has come to your help. God bless and have a nice day ahead!
