Answer:
8
Explanation:
Here we're dealing with the root mean square velocity of gases. We'll provide the formula in order to calculate the root mean square velocity of a gas:

Here:
is the ideal gas law constant;
is the absolute temperature in K;
is the molar mass of a compound in kg/mol.
We know that the gas from the red container is 4 times faster, as it takes 4 times as long for the yellow container to leak out, this means:

We also know that the temperature of the red container is twice as large:

Write the ratio of the velocities and substitute the variables:

Then:

From here:

Then:

Answer:
Fe
Explanation:
<em>Ferrum</em><em> </em>[Iron] has the most stable nucleus because of <em>binding</em><em> </em><em>energy</em><em> </em><em>per</em><em> </em><em>nucleon</em><em>.</em><em> </em>Although Uranium<em> </em>is<em> </em>another possibility, in this case, it is more radioactive than Iron. It disintegrates very swiftly that all is done so, just to achieve stability.
I hope this helps you out alot, and as always, I am joyous to assist anyone at any time.
Answer:
Well,
Conducting rods are good for detecting oscillating electric fields and conducting loops are good for detecting the presence of radio waves.
Number of electron pairs = \frac{1}{2}[V+N-C+A]
2
1
[V+N−C+A]
V = number of valence electrons present in central atom
N = number of monovalent atoms bonded to central atom
C = charge of cation
A = charge of anion
SbCl_5SbCl
5
:
In the given molecule, antimony is the central atom and there are five chlorine as monovalent atoms.
The number of electron pairs are 5 that means the hybridization will be sp^3dsp
3
B and geometry of the molecule will be trigonal bipyramidal.
There are a total of 4 elements
