let the moles of chlorine-35 is n1 and chlorine-37 is n2
now we will use the formula of average atomic mass
here let say
so here since ratio of moles of chlorine 35 and chlorine 37 is more than 1 so chlorine 35 is more in the proportion in this mixture so <em>there is most chlorine atom consist of 18 neutrons</em>
Our sun is AVERAGE in every way among the known stars, including mass, age, size, temperature, etc. It doesn't stand out in any way.
The answer is:
when Bohr's original model stated that electrons were tiny little objects circling the nucleus along fixed orbits, however, this is no longer valid as we now know that rather "circling" the nucleus at confined orbits, electrons can seem to be everywhere at once
.
-So, The correct answer for this question would be QUANTIZATION OF ENERGY. The aspect of Bohr's original model of electron structure that is still included in the currently accepted theory of electron structure is the quantization of energy.
-Bohr suggested circular orbits of electrons around the nucleus of a hydrogen atom, but researches have shown that motion of the electron is not in a single plane., but it takes place in three-dimensional space. Actually, the atomic model is not flat
.
Answer: the atmospheric pressure is generally expressed in terms of the height of the mercury column.at normal temperature and pressure, the barometric height is 760mm at sea level which is taken as one atmosphere. thus atmospheric pressure is also expressed in a unit atmosphere where 1 atm= 0.76m of hg. 9
Answer:
-14.2m/s
Explanation:
Given parameters:
Initial velocity of the ball = 25m/s
Time = 4s
Unknown:
Final velocity of the ball = ?
Solution:
To solve this problem, we use the expression below;
v = u - gt
v is the final velocity
u is the initial velocity
g is the acceleration due to gravity
t is the time
v = 25 - (9.8 x 4) = -14.2m/s
