How do you write an email that will get a response? 10 rules for writing emails that always get a reply Don’t waste the subject line. The subject line is your first (and sometimes last) chance to get someone to open your email. Add a sense of urgency (…if it’s urgent) Be casual and use […]
What type of charge transfer occurs when two objects are rub together?
What type of charge transfer occurs when two objects are rub together? When two different materials are rubbed together, there is a transfer of electrons from one material to the other material. This causes one object to become positively charged (the electron loser) and the other object to become negatively charged (the electron gainer). How […]
What is the effect of pressure on state of matter?
What is the effect of pressure on state of matter? Changes in presure have very little effect on the volume of a liquid. Liquids are relatively incompressible because any increase in pressure can only slightly reduce the distance between the closely packed molecules. If the pressure above a liquid is increased sufficiently, the liquid forms […]
Why is sodium chloride not poisonous?
Why is sodium chloride not poisonous? Salt water is full of sodium chloride molecules. are not poisonous and reactive like sodium metal and chlorine gas because they are electrically charged atoms called “ions.” The sodium atoms are missing their outer electron. Why does sodium chloride explode in water? Scientists who’ve also experimented with molten salt […]
Is chalk a precipitate?
Is chalk a precipitate? Composition: Chalk is a form of calcium carbonate, having the same chemical composition as ground calcium carbonate, limestone, marble, and precipitated calcium carbonate (PCC). In fact, all of the calcium carbonates listed in the previous sentence have the same crystal form, calcite. What is the purpose of the chalk lab? Purpose: […]

What is voltage in real life?
What are the 5 principles of the kinetic molecular theory of gases?
What are the 5 principles of the kinetic molecular theory of gases? The five main postulates of the KMT are as follows: (1) the particles in a gas are in constant, random motion, (2) the combined volume of the particles is negligible, (3) the particles exert no forces on one another, (4) any collisions between […]
How do humans withstand pressure?
How do humans withstand pressure? Answer 1: Our bodies are strong enough to resist the forces that compress us. A good analogy is blowing up a balloon. When the balloon is small even though the pressure of air inside the balloon exceeds the surrounding pressure, the strength of the elastic balloon is great enough to […]
What are 2 chemical properties?
What are 2 chemical properties? Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion. Iron, for example, combines with oxygen in the presence of water to form rust; chromium does not oxidize (Figure 2). What is water physical properties? Physical properties Selected physical properties of water melting point 0.00 […]
