Explanation:
MOLECULAR REACTION EQUATION;
Al(NO3)3(aq) + 3NaOH(aq) --->Al(OH)3(s) +3NaNO3(aq)
complete ionic equation:
Al^3+(aq) + 3NO3^-(aq) + 3Na^+(aq) + 3OH^-(aq) ---->Al(OH)3(s) + 3Na^+(aq) + 3NO3^-(aq)
Net ionic reaction equation;
Al^3+(aq) + 3OH^-(aq) ------> Al(OH)3(s)
Thermal energy will flow from an object high temperature to an object of low one. In this case, the thermal energy will flow from object B to object A.
Photoelectric effect, phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation.
mark me brainliestt :))
The sum of angels of a quadrilateral is equal to 360°.
∠A = 360 - (60 + 45 + 100) = 155
