Answer
0.496g
Explanation:
All you have to do in this problem is multiply .243 g by 2.04, which is the universal shortcut for these acid problems.
Answer:
Because kinetic energy is proportional to the velocity squared, increases in velocity will have an exponentially greater effect on translation kinetic energy. Doubling the mass of an object will only double its kinetic energy, but doubling the velocity of the object will quadruple its velocity.
Answer:
3.36 × 10^-19 J
Explanation:
From the formula;
E= hc/wavelength
h= 6.6 ×10^-34 Js
c= 3 × 10^8 ms-1
Wavelength= 589 ×10^-9 m
E= hc/ wavelength
E=6.6 ×10^-34 × 3 × 10^-8/ 589 ×10^-9
E= 3.36 × 10^-19 J
This can be solved according to Le C ha.tellors principle
- Any change in concentration, temperature, pressure can shift the equilibrium
So
Here to increase NO_2
We need to increase the temperature or increase the concentrations of reactants
