It is solid at room temperature.(a) (i) Solid magnesium cannot be compressed.Why?(ii) Solid magnesium cannot flow, but liquid magnesium can flow.Explain why.(iii) Magnesium gas completely fills any container it is put in.Explain why.(b) Magnesium reacts with water. Magnesium hydroxide, ...
As an example, helium is used to inflate a balloon instead of hydrogen gas because hydrogen is much more reactive than helium. Answer and Explanation: The temperature of the hand is 37∘C while the room usually has a temperature of 20...
Most elements of the periodic table are solid at room temperature. Some of them are gases at room temperature. The gas elements are all noble gases plus nitrogen, oxygen, fluorine, chlorine and hydrogen. There are only two elements with the liquid state among all elements....
hr. The reaction iscarefully quenched at room temperature by dropwise addition of 1 : 1 water : acetic acid (ca.20 mL) with stirring until no more gas evolution occurs. The reaction is concentrated at roomtemperature and water pump pressure to a slurry by removal of most of the ...
Hydrogen behaves as a metal 01:43 With the decrease in temperature, the proportion of which allotropic f... 02:59 A sample of water contains sodium chlorde. It is 01:46 Brackish water mostly contains 01:03 pH of neutral water at room temperature is nearly 02:32 Solubility of calcium sul...
H2Ois a liquid while hydrogen sulphide is a gas at room temperature. Give reasons. View Solution Answer the following: WhyH2Ois a liquid whereasH2Sis gas at room temperature? View Solution Give reason: H_2O is a liquid while H_2S is a gas at room temperature. ...
The column temperature was 801C; the carrier gas was 100% hydrogen with a flow rate of 21.5 ml min–1. Samples were directly injected onto the column. For all gas measurements, the system was routi- nely calibrated with certified standards (H2 and CH4: 2, 50, 1000 ppmv; CO2: 500, ...
Phase at room temperature: Solid Melting point: 356.9 degrees Fahrenheit (180.5 degrees Celsius) Boiling point: 2448 degrees Fahrenheit (1342 degrees Celsius) Number of isotopes (atoms of the same element with a different number of neutrons): 10; 2 stable Most common isotopes: Li-7 (92.41 perc...
Room temperature is a standard temperature used in chemistry and is equal to 25 Celsius degrees. It is part of the Standard Ambient Temperature and Pressure (SATP), which refers to fixed temperature and pressure points used in calculations. Another ...
