C) medium.
The medium of a wave is any substance that carries the wave, or through which the wave travels.Ocean waves are carried by water, sound waves are carried by air, and. the seismic waves of an earthquake are carried by rock and soil.
1.04gK*1molK/39.01g K= 0.0267 mol K
0.70gCr*1mol/52.0g Cr = <span>0.0135 mol Cr
0.86 gO* 1 mol/16.0 g O = 0.0538 mol O
</span>0.0267 mol K/0.0135 = 2 mol K
0.0135 mol Cr /0.0135= 1 mol Cr
0.0538 mol O/0.035= 4 mol Cr
K2CrO4
Answer:
(e) CO2 is formed twice as fast as ethane is consumed.
Explanation:
Since we have the equation of the reaction as;
2C2H6(g) + 7O2(g) 4CO2(g) + 6H2O(l)
The rate of consumption of ethene = -1/2 d[C2H6]/dt
Rate of production of CO2= 1/4 d[CO2]/dt
Hence, CO2 is formed twice as fast as ethane is consumed.
Both the atoms are of the same element but one of them is electrically neutral and the other has a stable electronic configuration.
<h3>What is the meaning of a neutral atom?</h3>
An atom is said to be neutral because it has an equal number of electrons and protons in it.
If two different atoms have nine protons each and the same mass but one is neutral while the other has a negative charge.
This implies both the atoms have the same nucleus but different charges so it can be concluded that they are both the atoms of the same element but one of them is electrically neutral and the other has gain electron from other element and have stable electronic configuration.
