Answer:
C.
Explanation:
Since they're changing from a gas to a liquid, the particles are getting squished together more if that makes sense. They're not vibrating that fast anymore when they're in liquid form.
Models help us to understand the properties of molecules and help us to predict the kind of reactions they undergo.
A molecular model is a three dimensional representation of a molecule. Usually, molecular models could either be;
- Ball and stick models or
- Space filling models.
In either case, the model gives us a vivid representation of the molecule and enables us to predict its properties and reactivity based on the the inter-connectivity of atoms in the structure as shown in the model. The model of H2SO4 as shown gives us an idea of its properties and its reactivity.

Answer: B (Items with densities lower than water will sink due to surface tension)
Explanation:
Surface tension is an intermolecular force exerted on the surface of water making it like a stretch elastic skin. Surface tension enables items with lesser densities than water, to float and slide on a water surface. Examples insects, leaves, paper etc
According to Archimedes principle an object denser than the fluid will sink. While objects less dense than the fluid will float.
Answer is (B) is false because items with densities higher then water will sink due to surface tension
