What are the six properties of metals? Metals Lustrous (shiny) Good conductors of heat and electricity. High melting point. High density (heavy for their size) Malleable (can be hammered) Ductile […]

What was the Beatles last hit song? The Long And Winding Road How do I know if my Abbey Road is original? Best way to tell if a record is genuine, firstly is by the Matrix number. Its engraved very small near to the label. It should be printed as if its done by hand […]

Which orbitals Cannot form a pi bond? dx2−y2+py sideways overlapping does not form π-bond as the two orbitals do not have proper orientation for the overlap. Was this answer helpful? Can pi bonds be formed in absence of sigma bonds? Yes, there exists pi bonds without coexisting sigma bonds. Here both the bonds of the […]

What does it mean when a force is balanced? Balanced forces are equal in size and opposite in direction. When forces are balanced, there is no change in motion. In one of your situations in the last section, you pushed or pulled on an object from opposite directions but with the same force. What is […]

Where is productive efficiency? In long-run equilibrium for perfectly competitive markets, productive efficiency occurs at the base of the average total cost curve — i.e. where marginal cost equals average total cost — for each good. What is meant by productive efficiency? Production efficiency is an economic term describing a level in which an economy […]

What is hydrogen bonding explain with example? : an electrostatic attraction between a hydrogen atom in one polar molecule (as of water) and a small electronegative atom (as of oxygen, nitrogen, or fluorine) in usually another molecule of the same or a different polar substance. Other Words from hydrogen bond Example Sentences Learn More about […]

Why does the solution conduct electricity when the crystals dissolved in water? When a crystal of an ionic compound dissolves in water, the ions separate. Again, the ions are free to move – so a solution of an ionic compound in water also conducts electricity. Which compound has the most ionic character? The greatest the […]

What is the SI unit of current? ampere How do you measure current in a DC circuit? It is measured in the unit of the Ampere, simply called “Amp,” (A). The most common way to measure current in a circuit is to break the circuit open and insert an “ammeter” in series (in-line) with the […]

Is pollution really a problem? One of the greatest problems that the world is facing today is that of environmental pollution, which is causing grave and irreparable damage to the natural world and human society with about 40% of deaths worldwide being caused by water, air and soil pollution and coupled with human overpopulation has […]

What are the natural variables of Helmholtz free energy? The natural variables are temperature, T, and volume, V . If the temperature and volume are held constant, the system will reach the equilibrium state (pressure, P, and entropy, S) with the minimum Helmholtz free energy. What are the four thermodynamic functions? Four important and useful […]
