Question

here are four sketches of substances. each sketch is drawn as if a sample of the substance were under a microscope so powerful that individual atoms could be seen. decide whether each sketch shows a sample of an element, a compound, or a mixture. substance x: element compound mixture substance y: element compound mixture substance t: element compound mixture substance z: element compound mixture

Explanation:

Step1: Analyze Substance Z

It has molecules with two - different colored atoms (red and another color), indicating different elements bonded together, so it's a compound.

Step2: Analyze Substance X

All the molecules are identical and consist of two different - colored atoms (blue and red), meaning different elements are bonded, so it's a compound.

Step3: Analyze Substance T

There are two types of molecules present (one with blue - red combination and another with red - red combination), so it is a mixture of different substances.

Step4: Analyze Substance Y

All the particles are identical blue - colored molecules, representing the same element, so it is an element.

Answer:

Substance Z: compound
Substance X: compound
Substance T: mixture
Substance Y: element
