How do you calculate H+ concentration? Key Concepts The hydrogen ion concentration in a solution, [H+], in mol L-1, can be calculated if the pH of the solution is known. pH is defined as the negative logarithm (to base 10) of the hydrogen ion concentration in mol L-1 pH = -log10[H+] [H+] in mol L-1 […]
Why do humans behave the way they do psychology?
Why do humans behave the way they do psychology? The answer is deceptively simple and very powerful. People behave the way they do because… Their behavior gets them what they want. And, as a consequence, they won’t change their behavior until it stops getting them what they want. What are the two disciplines of psychology? […]
How do you check a buck converter?
How do you check a buck converter? Step-loads with rise/fall times of 200 ~ 500nsec will be sufficient to test the stability of most buck converters. Figure 2 shows a simple tool to generate fast load steps to a converter : A MOSFET driven by a pulse generator switches a load resistor on and off […]
What makes hydrogen peroxide and water different?
What makes hydrogen peroxide and water different? Its physical properties are very similar to those of water, except that it is 40% denser. The main difference between hydrogen peroxide and water, however, is in its chemical behaviour. The single bond between the two oxygen atoms is weak, so that H2O2 readily fragments into either H […]
Can Magnesium be broken down by chemical means?
Can Magnesium be broken down by chemical means? Reason: when it said a substance, think of the matter chart. Substances can be broken down to a compounds or elements. Beryllium, Boron, and Magnesium are elements and Methanol is a compound which can be chemically change. Can arsenic be broken down by a chemical change? Arsenic […]
Is it OK to mix rubbing alcohol and hydrogen peroxide?
Is it OK to mix rubbing alcohol and hydrogen peroxide? From a chemical perspective, mixing hydrogen peroxide solution and isopropyl alcohol is safe. They won’t react together without the right catalyst. To minimise the possibility of a reaction, it would be best to mix them together just before use. Does bleach and ammonia make mustard […]
What is an example of sound energy?
What is an example of sound energy? Sound energy is produced when an object vibrates. The sound vibrations cause waves of pressure that travel through a medium, such as air, water, wood or metal. What is heat energy in simple words? Heat energy is the result of the movement of tiny particles called atoms, molecules […]
How the resistance of a wire depends on its length?
How the resistance of a wire depends on its length? The relationship between resistance and wire length is proportional . The resistance of a thin wire is greater than the resistance of a thick wire because a thin wire has fewer electrons to carry the current. The relationship between resistance and the area of the […]
How was the Hubble constant discovered?
How was the Hubble constant discovered? How the Hubble constant was discovered. The Hubble constant was first calculated in the 1920s, by American astronomer Edwin Hubble. By knowing how bright a Cepheid truly is and how dim its light appeared when seen from Earth, Hubble was able to derive the Cepheid’s distance. Which Hubble plot […]
Which best describes why a diamond ring will sometimes?
Which best describes why a diamond ring will sometimes? Answer Expert Verified. The correct answer should be refraction. Similar things occur with water vapor that gets hit by sun rays after rain. Are alpha waves good? Since alpha waves are linked with relaxed mental states, many experts believe increasing alpha activity may help reduce stress […]
