How does a ionic bond form?
How does a ionic bond form? An ionic bond is formed by the complete transfer of some electrons from one atom to another. The atom losing one or more electrons becomes a cation—a positively charged ion. The atom gaining one or more electron becomes an anion—a negatively charged ion. What must occur for an ionic […]

How did Dmitri Mendeleev impact the world?
How did Dmitri Mendeleev impact the world? Lived 1834 – 1907. Mendeleev’s wish led to his discovery of the periodic law and his creation of the periodic table – one of the most iconic symbols in science: almost everyone recognizes it instantly: science has few other creations as well-known as the periodic table. Can you […]
Why different objects kept on a table at room temperature do not exchange heat with table?
Why different objects kept on a table at room temperature do not exchange heat with table? Answer. Answer: The sense of touch allows us to recognise temperature differences of objects in the same room which we could easily assume should all be at that same room temperature. The temperature of an object is dependant on […]
What is the melting point of acetic acid?
What makes the ball keeps on rolling?
What makes the ball keeps on rolling? When a rigid ball rolls on a plane with no other forces, it is known that no friction applies and the ball keeps rolling. Static friction applies in the opposite direction of the tangential part of the external force, with equal magnitude. What do you call the force […]
What is the function of pupil of eye?
What is the function of pupil of eye? The function of the pupil is clearly that of controlling the amount of light entering the eye, and hence the light reflex. Can an eye repair itself? Minor superficial scratches on the cornea will usually heal by themselves within two to three days. In the meantime, some […]
How do you kill Bacillus anthracis endospores?
How do you kill Bacillus anthracis endospores? anthracis are killed by UV radiation, dry heat, wet heat and desiccation. Methods and results: Hydrated B. anthracis spores were HTGE treated at c. 220°C for 50 ms, and the treated spores were tested for germination, mutagenesis, rupture and loss of dipicolinic acid. Why does Bacillus anthracis form […]
