How many moles of oxygen are in 2 moles of CO2? A mole of CO2 molecules (we usually just say “a mole of CO2”) has one mole of carbon atoms and two moles of oxygen atoms. How many oxygen atoms are there in 5 moles of CO2? Hence, number of moles of Oxygen in 5 […]
Which equation should be used for a bomb calorimeter?
Which equation should be used for a bomb calorimeter? Constant-Pressure Calorimetry In contrast, a bomb calorimeter ‘s volume is constant, so there is no pressure-volume work and the heat measured relates to the change in internal energy (ΔU=qV Δ U = q V ). Does a bomb calorimeter measure delta H directly? The combustible gas […]
How many tidal bulges are there in a day?
How many tidal bulges are there in a day? two tidal What causes tidal forces? Gravity is one major force that creates tides. In 1687, Sir Isaac Newton explained that ocean tides result from the gravitational attraction of the sun and moon on the oceans of the earth (Sumich, J.L., 1996). Why do tidal forces […]
What is the principle of calorimetry?
What is the principle of calorimetry? The principle of calorimetry indicates the law of conservation energy, i.e. the total heat lost by the hot body is equal to the total heat gained by the cold body. What is the calorimetry method? Calorimetry method Measure a volume of an acid and place into a polystyrene cup […]
What would happen if there was no moon?
What would happen if there was no moon? The moon affects the angle of the Earth’s tilt. The moon influences life as we know it on Earth. It influences our oceans, weather, and the hours in our days. Without the moon, tides would fall, nights would be darker, seasons would change, and the length of […]

Is air lighter than water?
Is air lighter than water? 5 Answers. Air is lighter because there are fewer molecules per unit volume compared with a unit volume of liquid water. A mole of water is 18 grams, so a liter of water contains about 55 moles (1000 grams). A mole of air at standard temperature and pressure, however, occupies […]
When sugar is dissolved in water the resulting solution is classified as a?
How do you balance charges?
How 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. What is redox reaction explain with an example? Every chemical reaction in which the oxidation number of a […]
