Answer:
The appropriate option will be Option A (unequal sharing of electrons in a covalent bond).
Explanation:
- A polar bond seems to be a covalent bond amongst two or even more atoms where there is an uneven distribution of the electrons surrounding the connection.
- This induces a small electrical magnetic dipole in the molecules whereby the end becomes generally favorable and another is mildly controversial.
The other choices aren't relevant to the situation presented. The answer above would be appropriate.
The vertical component of velocity is zero
We want to solve Q = mcΔT for the liquid water; its change in temperature will tell us the amount of thermal energy that flowed out of the reaction. The specific heat, c, of water is 4.184 J/g °C.
Q = (72.0 g)(4.184 J/g °C)(100 °C - 25 °C) = 22593.6 J
Q ≈ 2.26 × 10⁴ J or 22.6 kJ (three significant figures).
The smallest unit of an element that retains the chemical and physical properties of an element is an Atom.
Q is the heat added to the system.
