False. Pure substances cannot be separated by physical means. They are chemically uniform and do not contain any impurities that can be separated through physical methods like filtration or distillation.
True. In the environment, matter is often found in the form of mixtures, where two or more substances are physically combined but retain their individual properties. This can include mixtures of solids, liquids, or gases in various combinations.
Yes,Heterogenious mixtures are mixtures in wich different mixtures and you can filter it. Homogenious is the oposite
All mixtures are a combination of two or more substances that are physically combined, not chemically bonded. Mixtures can be separated by physical means such as filtration or distillation. The properties of the components in a mixture remain unchanged.
True. Compounds and mixtures can be either synthetic or natural. Synthetic compounds are created by humans in a laboratory while natural compounds are found in nature. Similarly, mixtures can also be either synthetic or natural based on their origin.
FALSE It is true the above answer is wrong
True. Mixtures can often be separated by simple chemical means such as filtration, distillation, chromatography, or evaporation. These methods rely on differences in properties such as solubility, boiling point, or size to separate the components of the mixture.
false all solutions are mixtures but not all mixtures are solutions
No, it is not true.
False, the parts of mixtures are not chemically bound.
False. Pure substances cannot be separated by physical means. They are chemically uniform and do not contain any impurities that can be separated through physical methods like filtration or distillation.
Very True!
True
True
In the logical sense, sentences must be either true or false and not both. "This sentence is false" cannot be true because that would mean that it is false, and it cannot be both. It also cannot be false because that would mean that it is true, and it cannot be both. Therefore, if it is true or false, then it is both true and false. Therefore it is either neither true nor false or both true and false; therefore, in the logical sense, it is not a sentence. However, it says it is a sentence; therefore, it is lying; therefore, it is false.
