The oxide formed by the chemical reaction of hydrogen and oxygen is acidic in nature write the correct statements |
|
Answer» Oxides are chemical compounds with one or more oxygen atoms combined with another ELEMENT (e.g. LI2O). Oxides are binary compounds of oxygen with another element, e.g., CO2, SO2, CAO, CO, ZnO, BaO2, H2O, etc. These are termed as oxides because here, oxygen is in combination with only one element. Based on their acid-base characteristics oxides are classified as acidic, basic, amphoteric or neutral:An oxide that combines with water to give an acid is termed as an acidic oxide.The oxide that gives a base in water is known as a basic oxide.An amphoteric solution is a substance that can chemically react as either acid or base.However, it is also possible for an oxide to be neither acidic nor basic, but is a neutral oxide.There are different properties which help distinguish between the three types of oxides. The TERM anhydride ("without water") refers to compounds that assimilate H2O to form either an acid or a base UPON the addition of water. |

C. The volume of water tank is 5m×4m×2m.if the tank is completely filled with water, calculate the pressure exerted at the bottom of the tank. |
|
Answer» tion:The volume of the water TANK = 5 * 3 * 2 = 30m^3.At 4°C = 39.2°F water has its greatest density ( p ) of 1. Its weight = 30,000kg.The Width and Length dimensions are not made clear in the specification.It is therefore IMPOSSIBLE to calculate the area upon which the weight RESTS and consequently determine the pressure = weight/area (N/m^2).There are three possible answers based upon the height of the tank water.Using: P = m * g * hP(h = 5) = 30,000 * 9.8 * 5 = 147MN/m^2.P(h = 3) = 30,000 * 9.8 * 3 = 882kN/m^2.P(h = 2) = 30,000 * 9.8 * 2 = 588kN/m^2.182 viewssubstitute the VALUE in the followingmark has brainliest |
