Answer:
AlCl₃ + 3NaOH → 3NaCl + Al(OH)₃
Explanation:
Problem is to balance the given chemical equation:
Equation:
AlCl₃ + NaOH → NaClO₂ + Al(OH)₃
Balancing a chemical equation involves the conservation of atoms on both sides of the equation.
We can use a very simple mathematical method to balance the above equation;
aAlCl₃ + bNaOH → cNaCl + dAl(OH)₃
a, b, c and d are coefficients that will balance the equation:
Conserving Al: a = d
Cl: 3a = c
Na: b = c
O: b = 3d
H: b = 3d
Assume that a = 1;
c = 3
b = 3
d = 1
AlCl₃ + 3NaOH → 3NaCl + Al(OH)₃
O₂ in from of the NaClO₂ flouts the rule of chemical combination
Answer:
thermal energy: the part of total internal energy that can be transferred (a portion of the kinetic energy)
heat is the thermal energy that flows from one substance to another due to a temperature difference.
Thermal energy is measured in temperature change.
Thermal energy transfer stops when thermal equilibrium is achieved (Both substances at the same temperature).
conduction: Transfer of thermal energy through a solid object like heat transferring up a metal spoon from a hot cup of coffee.
convection: the transfer of thermal energy due to the movement of a liquid or gas caused by differences in temperature. Only in a fluid (liquid or gas). Breezes, ocean currents.
radiation: Transfer energy with or without matter. Warming from the Sun, microwave oven.
Answer:
yes it is a chemical reaction
Explanation:
because the substances combined and made something new
