ok im not full sure man but i would say multiple voltaic cells that have spontaneous half reactions
im sorry hope it helps
Temperature is the measure of kinetic energy and when temperature increases so does the particles. heat is the measure of the flow of thermal energy and how to easily understand this is when u feel hot, u adjust the temperature so it’s cooler :)
The rate of effusion of gas B is 728.32 m/s
<u>Explanation:</u>
Given:
Mass of A, m₁ = 46 g/mol
Rate of effusion of A, R₁ = 515 m/s
Mass of B, m₂ = 92 g/mol
Rate of effusion of B, R₂ = ?
We know:
![\frac{R_1}{R_2} = \sqrt{\frac{M_2}{M_1} }](https://tex.z-dn.net/?f=%5Cfrac%7BR_1%7D%7BR_2%7D%20%3D%20%5Csqrt%7B%5Cfrac%7BM_2%7D%7BM_1%7D%20%7D)
Substituting the value we get:
![\frac{515}{R_2} = \sqrt{\frac{92}{46} } \\\\\frac{515}{R_2} = \sqrt{2} \\\\R_2 = \frac{515}{\sqrt{2} } \\\\R_2 = 728.32 m/s](https://tex.z-dn.net/?f=%5Cfrac%7B515%7D%7BR_2%7D%20%3D%20%5Csqrt%7B%5Cfrac%7B92%7D%7B46%7D%20%7D%20%5C%5C%5C%5C%5Cfrac%7B515%7D%7BR_2%7D%20%3D%20%5Csqrt%7B2%7D%20%5C%5C%5C%5CR_2%20%3D%20%5Cfrac%7B515%7D%7B%5Csqrt%7B2%7D%20%7D%20%5C%5C%5C%5CR_2%20%3D%20728.32%20m%2Fs)
Therefore, the rate of effusion of gas B is 728.32 m/s
Formula of isocyanic acid is HNCO. It colourless, volatile compound. It is poisonous inorganic compound. Melamine is synthesized from urea. The reaction involves two steps. In first step, urea gets converted to isocyanic acid which is an intermediate. In the second step, isocyanic acid gives melamine (molecular formula C₃H₆N₆) and carbon dioxide (CO₂). The balanced chemical reaction involved in second step is given below:
6 HNCO → 1 C₃N₃(NH₂)₃ + 3CO₂
The co-efficient of the reaction are: 6, 1, 3
The idea that synthetic items are bad can be correct but not in all situations. Synthetic items have been made to make life easier.
