The more electronegative an atom is, the more strength it has to pull electrons closer to itself. If one atom is highly electronegative and the other is barely electronegative then an ionic bond will form. If one is highly electronegative and the other is slightly electronegative, then a polar covalent bond will form. If they are both the same electronegativity then a nonpolar covalent bond will form.

Answer:
Gold is an element even when it is in a solution
Answer:
237.80mL
Explanation:
Molarity of a solution can be calculated using the formula;
Molarity = number of moles (n) ÷ volume (V)
However, we first need to calculate the number of moles of Cu(NO3)2 by using the formula:
moles = mass/molar mass
Molar mass of Cu(NO3)2 = 187.56 g/mol
moles = 146.59 ÷ 187.56
moles = 0.782moles
Molarity = n/V
3.28 = 0.78/V
V = 0.78/3.28
V = 0.2378L
In milliliters (mL), 0.24 litres = 0.24 × 1000
= 237.80mL
The distance traveled by light : 1.86 x 10⁵ miles
Explanation:
Given
speed of light=v=1.86 x 10⁵ miles/s
time=1 s
Required
distance of light travel
Solution
The motion of light can be considered as motion that has a constant velocity so that it can be classified as a straight, regular motion that has no acceleration
Can be formulated
![\tt \boxed{\bold{d=v\times t}}}](https://tex.z-dn.net/?f=%5Ctt%20%5Cboxed%7B%5Cbold%7Bd%3Dv%5Ctimes%20t%7D%7D%7D)
For the distance traveled by light in the above problem becomes:
![\tt d=1.86\times 10^5~miles/s\times 1~s\\\\d=\boxed{\bold{1.86\times 10^5~miles}}}](https://tex.z-dn.net/?f=%5Ctt%20d%3D1.86%5Ctimes%2010%5E5~miles%2Fs%5Ctimes%201~s%5C%5C%5C%5Cd%3D%5Cboxed%7B%5Cbold%7B1.86%5Ctimes%2010%5E5~miles%7D%7D%7D)
