Answer:
The SAE curriculum includes practical farming tasks conducted outside the scheduled classroom and laboratory period by students. SAEs offer a method for students in agricultural education to gain real-world work opportunities that they are most interested in in the field of agriculture. Supervised agricultural experience is an essential component of agricultural education, and all Agriculture, Food and Natural Resources (AFNR) courses are a necessary component.

Answer:
Weak bonds require less energy to form than strong bonds
Explanation:
According to Coulomb's law, the force between two species is inversely proportional to the distance between them. That said, the bigger the atoms are, the greater the bond length should be to form a molecule.
As a result, for a greater bond length, the attraction force is lower than for a shorter bond length. This implies that large atoms would form weak bonds and small atoms would form strong bonds.
Bond energy is defined as the amount of energy required to break the bond. If a bond is weak, it would require a low amount of energy to break it. This is also true for energy of formation, as it's the same process taking place in the opposite direction.

Answer:
X5Y2
Explanation:
% composition of X = 52.2%
% composition of Y = (100 - 52.2) = 47.8%
This means that there are 52.2g of X and 47.8g of Y in the compound
To calculate the empirical formula of the compound, we first convert the gram value to mole value by dividing by their molar masses.
X = 52.2g/42.3g/mol = 1.234mol
Y = 47.8g/96.7g/mol = 0.494mol
Next, we divide each mole value by the smallest value (0.494mol)
X = 1.234mol ÷ 0.494mol = 2.49
Y = 0.494mol ÷ 0.494mol = 1
We multiply each value by 2
X = 2.49 × 2 = 4.98
Y = 1 × 2 = 2
The simple ratio of X:Y is 5:2, hence, their empirical formula is X5Y2.
