What is the rate constant at 500K?
What is the rate constant at 500K? The rate constants of a reaction at 500K and 700K are 0.02s−1and 0.07s−1respectively. What is the value of the equilibrium constant KC at 700 K? At 700 K the equilibrium constant KC for the reaction between NO(g) and O2(g) forming NO2(g) is 8.7 × 106. The rate constant […]
What triggered big bang?
What triggered big bang? Over billions of years, stars “cook” hydrogen and helium atoms in their hot cores to make heavier elements like carbon and oxygen. Large stars explode over time, blasting these elements into space. This matter then condenses into the stars, planets, and satellites that make up solar systems like our own. Is […]
What is the opposite of scientific theory?
What is the opposite of scientific theory? A theory is a proposed explanation of something. But when people say that something is “just a theory,” they mean that it hasn’t been proven. This is because one sense of “theory” is “speculation.” However, in scientific writing, it means the complete opposite of this. What is theory […]
How many drops are in the ocean?
How many drops are in the ocean? There is an estimated 1.332 billion cubic kilometers of sea on Earth and 0.05 ml of water in a drop, so the ocean is equivalent to 2.664 × 10^25 drops or 26,640,000,000,000,000,000,000,000.

Which process could cause ice to form? Adding heat can cause ice (a solid) to melt to form water (a liquid). Removing heat causes water (a liquid) to freeze to form ice (a solid). Which example best illustrates adhesion? The water drop is composed of water molecules that like to stick together, an example of […]

What happens if new information is found to challenge an existing theory?
What happens if new information is found to challenge an existing theory? In science, a tested explanation of why things happen that is accepted to be true is called a scientific theory. Erroneous theories are wrong, although the scientists might not realize it at the time. The discovery of new evidence will cause them to […]
