Element on the right side of the periodic table differ from the elements on the left side in that elements on the <em>right side are non metallic and tends to be gases at room temperature.</em>
<em> </em><u>Explanation</u>
In the periodic table there element in the right side , left side and those which are in between.
- Example of element in the right side is fluorine chlorine, neon, Argon among others.
- This element have higher effective nuclear charges and stabilize electrons more effectively.
- there electrostatic intermolecular forces are generally weak therefore they exist in liquid or gaseous state.
Answer:
A unit for measuring work is called the foot-pound
Answer:
It will exert the pressure at a temperature of <em><u>153.44 K</u></em>
Explanation:
To answer this question, we shall be using the ideal gas equation;
PV = nRT
Since we are calculating the temperature, it can be made the subject of the formula.
Thus, this can be T = PV/nR
where P is the pressure = 900 torr
V is the volume = 0.75 L
n is the number of moles = 0.0705 mol
R is the molar gas constant = 62.4 L.Torr.
.
Plugging these values into the equation, we have;
T = (900 × 0.75)/(0.0705 × 62.4)
T = 153.44 K
Answer:
va/c = v a/b + v b/c
Explanation:
This is the correct formula for relative velocity
