The answer is N2 + 3H2 yields 2NH3. The oxidation-reduction reaction means that there is electrons transfer during the reaction which means that the valence changed.
<span>Scientists ignore the forces of attraction between particles in a gas under ordinary conditions</span><span> because the particles in a gas are apart and moving fast, rather than clustered and moving slow, therefore the forces of attraction are too weak to have a visible effect.</span>
<span>The cell would swell and burst, because the 20% salt solution is hypotonic with respect to the cell, causing a net movement of water into the cell. Example, water moves from the blood filtrate that will form urine. The same will do while pure water moved to seawater.</span>
Answer:
Sugar
Explanation:
Mixtures are substances that made of two or more elements or other substances that are joined together by physical methods and when mixed can be also be separated by physical method into the original individual elements.
Air is a mixture of gases such as oxygen, nitrogen, carbon dioxide and rare gases. When an amount of air is collected, its constituents can be collected separately.
Likewise 7 up and sea water
Sugar is a compound made of carbon, hydrogen and oxygen, when sugar is decomposed, it's original constituents are not recovered but sugar is decomposed into carbon dioxide and water
Answer:
25 g/hr
Explanation:
Remember that the rate of reaction refers to the rate at which reactants are used up or or the rate at which products appear.
Hence;
Rate of reaction = mass of reactant used up/time taken
Mass of reactant used up= 2g
Time taken = 5 minutes or 0.08 hours
Rate of reaction = 2g/0.08 hours = 25 g/hr
