Is a fruit salad heterogeneous mixture?

Yes, a fruit salad is a heterogeneous mixture.

A heterogeneous mixture is a mixture in which the components are not uniformly distributed throughout the mixture. This means that different parts of the mixture have different compositions. In the case of a fruit salad, the different fruits are not evenly distributed throughout the salad. Some parts of the salad may have more grapes, while other parts may have more strawberries. This uneven distribution of the components is what makes a fruit salad a heterogeneous mixture.
