Answer:
2PBr₃ + 3Cl₂ → 2PCl₃ + 3Br₂
2Na + MgCl₂ → 2NaCl + Mg
Explanation:
A balanced chemical equation is a chemical equation that have an equal number of elements of each type on both sides of the equation
Among the given chemical reactions, we have;
2PBr₃ + 3Cl₂ → 2PCl₃ + 3Br₂
In the above reaction;
The number of phosphorus, P, on either side of the equation = 2
The number of bromine atoms, Br, on either side of the equation = 6
The number of chlorine atoms, Cl, on either side of the equation = 6
Therefore, the number of elements in the reactant side and products side of the reaction are equal and the reaction is balanced
The second balanced chemical reaction is 2Na + MgCl₂ → 2NaCl + Mg
In the above reaction, there are two sodium atoms, Na, one magnesium atom and two chlorine atoms on both sides of the reaction, therefore, the reaction is balanced
The statement is an opinion because it expresses a preference of an individual than an actual fact.
If the first thing that the goslings saw was a dog, they would have followed the dog as a mother.
Imprinting refers to the process of training an animal to bond with anything it sees after birth even if it is not its real mother. Lorenz first achieved imprinting in 1935 using geese which followed him as their mother shortly after they were born.
If the geese were exposed to a dog, they could also have seen the dog as their mother and followed it accordingly shortly after birth.

Answer:18678.24pa or 0.184atm
Explanation: P= density *height *acceleration due to gravity
Density =13600kg/m^3
gravity =9.81m/s^2
H=0.140m
Pressure =13600*9.81*0.140
Pressure =18678.24pa or 0.184atm
