What has disrupted the carbon cycle in the last 150 years? Since the industrial revolution in the 19th century, carbon dioxide in the atmosphere has risen by 30%. Scientists have shown that this increase in carbon dioxide is a result of human activities that have occurred over the last 150 years, including the burning of […]
What are the examples of prefixes?
What are the examples of prefixes? A prefix is a group of letters placed before the root of a word. For example, the word “unhappy” consists of the prefix “un-” [which means “not”] combined with the root (or stem) word “happy”; the word “unhappy” means “not happy.” What are common prefixes? 12 Common Prefixes and […]
What does the 84 in krypton 84 mean?
When balancing equations do you balance charges?
When balancing equations do you balance charges? Balance charge. Add e- (electrons) to one side of each half-reaction to balance charge. You may need to multiply the electrons by the two half-reactions to get the charge to balance out. It’s fine to change coefficients as long as you change them on both sides of the […]

What is process water?
What is process water? Process water is broadly defined as water used in industry, manufacturing processes, power generation and similar applications. . Is process water pure? Distilled water is produced by a process of distillation. Distillation involves boiling the water and then condensing the vapor into a clean container, leaving solid contaminants behind. Distillation produces […]
What are 5 ways to conserve energy?
Can machine change the direction of force?
Can machine change the direction of force? Machines make work easier by increasing the amount of force that is applied, increasing the distance over which the force is applied, or changing the direction in which the force is applied. That’s because a machine doesn’t change the amount of work and work equals force times distance. […]
How entropy is a measure of disorder?
How entropy is a measure of disorder? Because work is obtained from ordered molecular motion, the amount of entropy is also a measure of the molecular disorder, or randomness, of a system. The concept of entropy provides deep insight into the direction of spontaneous change for many everyday phenomena. Does entropy mean disorder? Entropy is […]
