Chemist John Dalton described atoms as small spheres that could not be divided into anything smaller.
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.
Answer:
Explanation:
The formula for the heat released is
q = mCΔT
Data:
m = 395 g
C = 4.184 J·°C⁻¹g⁻¹
ΔT = 55 °C
Calculations:
q = 395 × 4.184 × 55 = 91 000 J = 91 kJ
The water will absorb 
of energy.
Since cells are hard to see the microscope helped them see. scientist were able to actually see cells in tissues placed under the microscope.
Answer:
We can solve this by the method of which i solved your one question earlier
so again here molar mass of C12H25NaSO4 is 288.372 and number of moles for 11900 gm of C12H25NaSO4 will be = 11900/288.372
which is almost = 41.26 moles
so to get one mole of C12H25NaSO4 we need one mole of C12H26O
so for 41.26 moles of C12H25NaSO4 it will require 41 26 moles of C12H26O
so the mass of C12H26O = 41.26× its molar mass
C12H26O = 41.26×186.34
= 7688.38 gm!!
so the conclusion is If you need 11900 g of C12H25NaSO4 (Sodium Lauryl Sulfate) you need C12H26O 7688.38 gm !!
Again i d k wether it's right or wrong but i tried my best hope it helped you!!
