Answer:
O, N, C, H
Explanation:
Electronegativity of an element is the property that combines the ability of its atom to lose or gain electrons. It measures the relative tendency with which the atoms of the element attracts valence electrons in a chemical bond.
On the periodic table, Electronegativity increases across the period but decreases down a group.
To solve the given problem, let us use thE Pauling's table of electronegativities to compare the electronegativities of the elements.
On the table:
C = 2.5
H = 2.1
O = 3.5
N = 3.0
In terms of decreasing electronegativities, the atoms are arranged as:
O N C H
Answer:
Digital scales /weight scales (the stuff you weigh yourself to see how much lbs you are)
Explanation:
The answer is:
the molarity = 50 moles/liters
The explanation:
when the molarity is = the number of moles / volume per liters.
and when the number of moles =2.5 moles
and the volume per liters = 0.05 L
so by substitution:
the molarity = 2.5moles/0.05L
= 50 moles /L
Answer:
Second option
Explanation:
We started using fossil fuels which are the main cause of climate change
Answer:
B. Add more chloride ions
Explanation:
Because we know based on lechatlier that any disturbance to equilibrium will make the shift act accordingly. If something is removed it wants to shift to side where it is removed to compensate for the change, if something is added it wants to move away from it to minimize the change.
Therefore, if you add chloride ions, the equilibrium shifts to left to make more solid lead chloride.
