Question

Identify the compound. Which of these is a compound?

Answer 1

Mercury is an element, white wine is a homogeneous mixture, ranch-style salad dressing is a heterogeneous mixture, and table sugar (sucrose) is a compound.

Step-by-step explanation:

When classifying a substance, we determine if it's an element, a compound, a heterogeneous mixture, or a homogeneous mixture (solution). Here's the classification of each listed substance:

• White wine is a homogeneous mixture because it is a blend of various substances that are evenly mixed, such as water, alcohol, and other components, but it does not have a fixed composition.
• Mercury is an element because it is a pure chemical substance consisting of one type of atom, represented on the periodic table by the symbol Hg.
• Ranch-style salad dressing is a heterogeneous mixture because it contains different ingredients that are not uniformly mixed and can often be seen as separate substances.
• Table sugar (sucrose) is a compound because it is a substance composed of two elements, carbon and oxygen, chemically bonded in a fixed ratio.

To summarize, mercury is an element, white wine and ranch-style salad dressing are mixtures, and table sugar is a compound.

Answer 2

Answer: Image 3 is a compound.

Explanation: A compound is something that consists of two or more different elements bonded chemically.

A molecule is formed when two or more elements combine chemically.

An element is described as something which cannot be broken down by any chemical means.

We are given 4 images.

Image 1 is an element as it is showing the shell structure of Oxygen (O) element.

Image 2 is an element as only 1 element is known that is Magnesium (Mg).

Image 3 is a compound as in the structure 2 elements are shown which is bonded together. Elements present in this are Carbon (C) and Oxygen (O).

Image 4 is a molecule as in the structure 2 H-atoms combine chemically, but it cannot be considered as compound as the two elements are not different.
