What are 4 major pollutants? The common air pollutants are: Particulate matter (PM10 and PM2. Ozone (O3) Nitrogen dioxide (NO2) Carbon monoxide (CO) Sulphur dioxide (SO2) What are major air pollutants their causes and effects on human body? Air pollution is also considered as the major environmental risk factor for some respiratory diseases such as […]
What is electronegativity How does it vary in group and period?
What is electronegativity How does it vary in group and period? The tendency of an atom to attract the shared pair of electrons towards itself is known as electronegativity. Electronegativity increases across a period while it decreases down a group. Atomic radius increases down the group due to addition of new shell. How does electronegativity […]
How is air pressure usually measured?
How is air pressure usually measured? A barometer is a scientific instrument used to measure atmospheric pressure, also called barometric pressure. The atmosphere is the layers of air wrapped around the Earth. That air has a weight and presses against everything it touches as gravity pulls it to Earth. Barometers measure this pressure. What time […]
What type of reaction is shown here C6H12O6 12o2 → 6CO2 +6H2O?
What type of reaction is shown here C6H12O6 12o2 → 6CO2 +6H2O? C6H12O6 +1202→ 6CO2 +6H20. Double replacement. Decomposition. What type of reaction is C6H12O6 6O2 6CO2 6H2O? We perform the reverse reaction, the oxidation of glucose, to harness the stored energy. C6H12O6 + 6O2 → 6CO2 + 6H2O + energy We store this energy […]
What is the primary role of frontal lobe?
What is the primary role of frontal lobe? As a whole, the frontal lobe is responsible for higher cognitive functions such as memory, emotions, impulse control, problem solving, social interaction, and motor function. Damage to the neurons or tissue of the frontal lobe can lead to personality changes, difficulty concentrating or planning, and impulsivity. Which […]
Is there a planet partially made of diamonds?
Is there a planet partially made of diamonds? In October 2012, it was announced that 55 Cancri e showed evidence for being a carbon planet. It has eight times the mass of Earth, and twice the radius. Research indicates that the 2,150 °C (3,900 °F) planet is “covered in graphite and diamond rather than water […]
Are mass and force directly proportional?
Are mass and force directly proportional? Newton’s second law of motion (also known as the force law ) states that… net force is directly proportional to mass when acceleration is constant. … Does heat absorption depend on mass? The amount of heat absorbed depends on the mass of the body. The heat energy absorbed is […]
Where does the resistor go on a LED?
Where does the resistor go on a LED? Since this resistor is only being used to limit current through the circuit, it can actually be located on either side of the LED. Placing the resistor on the positive (anode) side of the resistor will have no differing effects from placing the resistor on the negative […]
What makes a DC motor more powerful?
What makes a DC motor more powerful? Yes, since the power of your motor is related to the voltage and the current, a higher wattage at the same voltage will result in higher torque. Q2: The voltage itself will only affect the speed, the current needs to be increased in order to increase the torque. […]
Does antiviral kill virus?
Does antiviral kill virus? Most antivirals target specific viruses, while a broad-spectrum antiviral is effective against a wide range of viruses. Unlike most antibiotics, antiviral drugs do not destroy their target pathogen; instead they inhibit its development. Do antivirals weaken immune system? Whereas AZT, ribavirin, or ganciclovir were antiproliferative, ddI or acyclovir had little, if […]
