Answer: Heterogenous
Explanation:
A heterogenous mixture is one where the composition of matter is not uniform throughout.
Some examples of heterogenous mixtures include: chocolate chip cookies, salad dressing, strawberry yogurt
15.0 moles of ammonium sulfate are formed by the reaction of 30.0 moles of ammonia with sulfuric acid.
Let's consider the reaction between ammonia and sulfuric acid to produce ammonium sulfate.
2 NH₃ + H₂SO₄ ⇒ (NH₄)₂SO₄
The molar ratio of NH₃ to (NH₄)₂SO₄ is 2:1. The moles of (NH₄)₂SO₄ produced from 30.0 moles of NH₃ are:

Explanation:
1. q=mcat
q = (20)(4.184)( 30-20)
q = 836.8
a. True
b. False
Answer:
The correct option is B) false.
Explanation:
Absolute zero is the point where it is not feasible to cool further.
The lowest possible temperature is 0 kelvin which is also known as absolute zero. In degrees its corresponds to –273.15 degrees Celsius.
it is not possible to reach or cool a substance to absolute zero although nearby temperatures can be reached.
Consider the provided statement.
Researchers have now been able to cool substances to absolute zero is a false statement.
The correct option is B) false.
B.a rock maintaining its solid shape
C.a koala using claws to hold onto a tree
A rock maintaining its solid shape is one that required intermolecular forces. Thus, option (B) is correct.
Intermolecular forces are those forces that maintain chemical interactions between molecules of a substance and other types of particles present in the substance.
Rocks are constructed of different particles held together by various types of intermolecular forces depending on the kinds of particles present in the rock. Intermolecular forces can occur among molecules and other particles in a solid compound.
Intermolecular forces can either be attractive forces or repulsive forces. The molecules of opposite charges such as positive and negative charges can have attraction between them. While repulsion occurs between particles with similar charges such as between positive and positive charges.
The Intermolecular forces maintain the integrity of the structure of that compound. Intermolecular forces in compounds exist such as electrovalent bonds, covalent bonds, Vander Waals forces, hydrogen bonds, etc.
