277.79 atm is the calculated gas pressure.
The ideal gas is a fictitious concept used to study how real gases behave by comparing them to their deviations. The pressure-temperature rules are followed by an ideal gas.
177 atm is the initial pressure. The starting temperature is 298 K (25 °C = 25 + 273 °C).
195°C = 195+273
= 468K is the final temperature.
The pressure temperature relation illustrated below can be used to get the final pressure.
P1/T1 = P2/T1
= P1T2/T1
= 177 atm 468 K /298 K
= 277.97 atm
The final pressure is therefore 277.97 atm.

Molar mass of Cu(NO3)2 = 187.56 g/mol
Mass = 122 g
number of moles:
n = m / mm
n = 122 / 187.56
n = 0.650 moles
n * 6.02x10²³ =
0.650 * 6.02x10²³ = 3.913 x 10²³ molecules
hope this helps!.
I would say B(make the ramp longer). That way they will have to exert less force in order for it to the desired height. If you think about it, it is harder to go up a really steep hill vs. a hill with a gradual incline, because you have to exert less force at any one given time.
Answer:
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
Order of the reaction is defined as the sum of the concentration of terms on which the rate of the reaction actually depends. It is the sum of the exponents of the molar concentration in the rate law expression.
For reactions which takes place in multiple steps are complex reactions and the order is given by the slowest step which is the rate limiting step.
For the given reaction, the rate limiting step is
Rate law will be ,
