How far will a car travel in 20 min at a speed of 10 m s? How much distance does he travel? speed = distance / time. With speed = 10 m/s and time = 20 x 60 s, the distance travelled = 10 x (20 x 60) m = 12 000 m or 12 […]
What happens when chlorine gas is treated with cold and dilute caustic soda?
What happens when chlorine gas is treated with cold and dilute caustic soda? Solution. When chlorine is passed through cold and dilute caustic soda solution, a mixture of sodium hypochlorite and sodium chloride is formed. How does sodium react with water? When sodium is added to water, the sodium melts to form a ball that […]
How many total oxygen atoms are there in the reactants of photosynthesis?
How many total oxygen atoms are there in the reactants of photosynthesis? six atoms Where do the oxygen atoms go? The single oxygen atoms latch onto O2 molecules to form O3 (the chemical formula for ozone). The stratosphere has higher concentrations of O3 because there is more UV present. The ozone layer filters out UV, […]
Why do electrons transfer from a sweater to a balloon?
Why do electrons transfer from a sweater to a balloon? Since electrons have a negative charge, the balloon now has a negative charge. But the sweater fibers lost some of their electrons, so now the fibers have a positive charge (they have more protons than electrons). Positive and negative attract so if you bring the […]

Why does a metal spoon feel colder than a wooden spoon?
Why does a metal spoon feel colder than a wooden spoon? Even though they are the same temperature, the metal will feel colder than the wood because of the thermal conductivity of the metal, compared to the wood. It is because the metal conducted heat faster that it feels colder than the wood, which conducted […]
Why is my geothermal heat blowing cold air?
What type of solution is seltzer water gas liquid liquid liquid metal liquid?
What type of solution is seltzer water gas liquid liquid liquid metal liquid? Multiphase Mixtures Carbonated water (or carbonated anything) is a multiphase heterogenous mixture, with gaseous carbon dioxide (CO2) bubbling through liquid water (H2O). Is soda in water a suspension? Is soda water a solution suspension or colloid? Soda-water, Milk, Brine, Blood, Ink, Smoke […]
How do I know when my electricity will come?
What will happen if tectonic plates are not moving?
What will happen if tectonic plates are not moving? One big problem with plate tectonics stopping is that plate motion is the mechanism by which Earth is cooling down and getting rid of its internal heat. If the plates stopped moving, the planet would have to find a new and efficient means to blow off […]
