Answer:
We can compare the both sample by taking into account the kinetic energy.
By increasing the temperature kinetic energy of gas molecules increased.
Explanation:
It is known that kinetic energy of molecules is increased by increasing the temperature.
We are given with two sample of hydrogen one is at 10°C and other is at 350 K.
Hydrogen sample at 10°C = 273.15 + 10 = 283.15 k
Thus one sample is at 283.15 K and other is at 350 K. So, the sample at higher temperature i.e 350 K will have more kinetic energy of molecules.
While the sample at 283.15 K will have less speed of molecule and kinetic energy.
solid : the molecules are tightly packed
liquid : the molecules have some space in them
gas : molecules can freely move around
Answer:
242.4 g
Explanation:
RAM of KNO3=39+14+(16×3)=101
Mass=morality×RAM
101*2.4=242.4
Answer:
hold on this will take me awhile
Explanation:
Solution :
From the balanced chemical equation, we can say that 1 moles of KBr will produce 1 moles of KCl .
Moles of KBr in 102 g of potassium bromide.
n = 102/119.002
n = 0.86 mole.
So, number of miles of KCl produced are also 0.86 mole.
Mass of KCl produced :
Hence, this is the required solution.
