228 amu
The correct answer is 76 amu. The total mass of the reactant molecules is 76 amu, and since they react to form a single molecule, the mass of the formed molecule remains the same.
A pen-and-pencil drawing of a building using two-point perspective is shown. The building is seen from the front, where the right and left sides meet, before the right and left sides angle back to the edge of the frame.

two vanishing points
only orthogonal lines
only orthogonal lines
imagery in the background larger than in the foreground
imagery in the background larger than in the foreground
imagery in the foreground lighter than in the background
imagery in the foreground lighter than in the background
The correct answer is "two vanishing points". In a two-point perspective drawing, two vanishing points are used to create the illusion of depth and to accurately depict the building's angles and dimensions.

The correct answer is "was able to create the illusion of depth." Value change refers to the variation in darkness or lightness in an image, and by using different values, an artist can create a sense of depth and dimension in the drawing.
