What is the difference between rate constant and rate of reaction? A rate constant, k, is a proportionality constant for a given reaction….Differences between the rate of reaction and constant: Rate of Reaction Rate Constant It depends upon the concentration of the reactant It is independent of the concentration of the reactant. What is relation […]

What is the difference between the chemical name and chemical formula? Chemical symbols refer to chemical elements only. They do not necessarily refer to atoms of that element, but also to ions. Chemical formulas refer to compounds and, specifically, the ratios in which it is made up by different chemical elements. What is the chemical […]

How do you convert a smaller unit to a larger unit? To convert a smaller unit to a larger unit (eg to ), divide it by the number of smaller units which are needed to make. To convert from a larger unit to a smaller one, multiply. To convert from a smaller unit to a […]

What is the Joule equal to? One joule equals the work done (or energy expended) by a force of one newton (N) acting over a distance of one meter (m). One newton equals a force that produces an acceleration of one meter per second (s) per second on a one kilogram (kg) mass. Therefore, one […]

Can a bulb added in a circuit with twisted wires light up? Answer. Answer: Yes,because it is still a complete circuit. What must be true for a circuit to light a bulb? Based on what you have seen, what must be true for a circuit to light a bulb? There has to be a lightbulb […]

Will a microwave explode? The water in their body heats up due to molecular resonance with the microwaves. Their eyeballs may explode from the pressure build-up as the water in them turns to steam with nowhere to escape. After a few minutes the heat will have penetrated deep into their bodies, causing their internal organs […]

What is the lowest temperature that a substance can reach? Absolute zero, technically known as zero kelvins, equals −273.15 degrees Celsius, or -459.67 Fahrenheit, and marks the spot on the thermometer where a system reaches its lowest possible energy, or thermal motion. There’s a catch, though: absolute zero is impossible to reach. What is 70 […]

Where are graphs used? Graphs are a common method to visually illustrate relationships in the data. The purpose of a graph is to present data that are too numerous or complicated to be described adequately in the text and in less space. How are bar graphs useful in real life? Bar graphs are an extremely […]
