What are three properties of acids? Acids Aqueous solutions of acids are electrolytes, meaning that they conduct electrical current. Acids have a sour taste. Acids change the color of certain acid-base indicates. Acids react with active metals to yield hydrogen gas. Acids react with bases to produce a salt compound and water. How many types […]

Why is there a difference between the core and the outer core? The temperature of the inner core is far above the melting point of iron. However, unlike the outer core, the inner core is not liquid or even molten. The liquid outer core separates the inner core from the rest of the Earth, and […]

How do I find my 14 pin IC? Pin numbers The pins are numbered anti-clockwise around the IC (chip) starting near the notch or dot. The diagrams show the numbering for 8-pin and 14-pin ICs, but the principle is the same for all sizes. How do I know my IC type? Read the serial number […]

Does high spin damage clothes? Myth: Higher spin speeds will ruin your clothes! Busted: No! Higher spin speeds will not ruin your clothes when you use the appropriate settings. High spin speeds are ideal for cottons, bulky items such as towels and bedding and denim. How long should you spin your clothes? A normal drying […]

Is Yahweh mentioned in the Bible? In Genesis 4:26 (in the J story), it is said, “At that time people began to call on the name of yhwh.” In E, on the other hand, the name yhwh is never used until Exodus 3:14-15 when God gives Moses the name by which he is to announce […]

Basically the process of control involves three steps i.e.- (i) setting up standards (ii) performance appraisal and (iii) corrective measures. What are the 3 types of control? Three basic types […]

How does covalent bonding affect melting point? Covalent compounds have bonds where electrons are shared between atoms. Due to the sharing of electrons, they exhibit characteristic physical properties that include lower melting points and electrical conductivity compared to ionic compounds. What type of bonding has the lowest melting point? Covalent Molecules Which bond is strongest […]
