Explanation:
Kinetic molecular theory of gasses stated that,
1) Gases consist of large number of smaller particles which are distance apart from each others.
2) The gas molecules collide with each other and also with wall of container and this collision is elastic.
3) Gas molecules are in continuous random motion and posses kinetic energy.
4) The forces of attraction between gas molecules are very small and considered negligible.
5) The temperature of gas is directly proportional to average kinetic energy of gas molecules.
Answer:
B.) +6
Explanation:
To find the oxidation number of sulfur, we can assume the oxidation numbers of the other elements.
What I mean is, oxygen (O) always has an oxidation number of (-2). That being said, if there are 4 oxygen atoms, oxygen is contributing -8 overall. We also know that hydrogen generally has an oxidation number of (+1). Like before, if there are 2 hydrogens, it must be contributing +2.
If the overall molecule is neutral, we have to get these charges to balance out.
In essence, -8 + 2 + ? = 0?
If you combine the charges from oxygen and hydrogen, you are left with -6. Therefore, to make the molecule neutral, sulfur must have an oxidation number of +6.
The rock cycle is the process of converting rock between igneous, sedimentary, and metamorphic forms. ... Molten rock inside the Earth undergoes a phase change as it cools to produce solid igneous rock. The chemical changes which form the rock depend on the type of minerals present and how fast the rock cools.
