<span>Firstly, we know that M= m/n, the main formula which shows the relationship
between m, n, and M. The nknown compound contains only carbon, hydrogen, and
oxygen, so we can get n(C)=m/M, from M(C)=
m(C)/n (C), besides the stoechiometric
equality, we have </span>
n( C)= m(C)/M(C ) = m(CO2)/ M(CO2)=11/44, because m(CO2)=11.0,
M(CO2)=44.01
so n(C )= 0.24moles,
Answer:
"The higher the spring constant, the stiffer the spring. The spring constant is not the same value for different elastic objects. For a given spring and other elastic objects, the extension is directly proportional to the force applied. For example, if the force is doubled, the extension doubles."
Explanation:
Answer:
alkaline earth metal
it's because calcium in the periodic table is located in group 2
At Equilibrium, The rate of formation of Products is equal to the rate of degradation of Reactants.
Hope this helps!
Answer:
A. 3
Explanation:
Given
The atomic radius of Hydrogen rH = 53 pm
The atomic radius of Uranium rU = 156 pm
we apply
rU / rH = 156 pm / 53 pm
⇒ rU / rH = 2.943 ≈ 3
then
rU = 3*rH
