What do the rows mean on a periodic table? Each row represents one period; the period number of an element indicates how many of its energy levels house electrons. Sodium, for instance, sits in the third period, which means a sodium atom typically has electrons in the first three energy levels. How do you identify […]
What is the difference between average acceleration and instantaneous acceleration?
What is the difference between average acceleration and instantaneous acceleration? Average acceleration is the change of velocity over a period of time. Instantaneous acceleration is the change of velocity over an instance of time. What’s the definition of instantaneous speed? Definition: When the speed of an object is constantly changing, the instantaneous speed is the […]
What charge do humans have?
What charge do humans have? Resting cells are negatively charged on the inside, while the outside environment is more positively charged. This is due to a slight imbalance between positive and negative ions inside and outside the cell. Cells can achieve this charge separation by allowing charged ions to flow in and out through the […]
Is PCl3 covalent or ionic?
Is PCl3 covalent or ionic? PCl3 has distorted structure due to the presence of lone pairs of electrons. (A) PCl3 Is contains three covalent bond which are formed by equal sharing of electron in between phosphorus atom and chlorine atom, hence it’s a covalent molecule. Does PCl3 contain ionic bonds? Phosphorus trichloride. Covalent bonding. Strong […]

Why is the Cenozoic Era important?
Why is the Cenozoic Era important? Cenozoic Era, third of the major eras of Earth’s history, beginning about 66 million years ago and extending to the present. It was the interval of time during which the continents assumed their modern configuration and geographic positions and during which Earth’s flora and fauna evolved toward those of […]
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?
