Q1. Give reasons:- 1. As we move from lithium to potassium, atomic size increases down the group. 2. Ionic compounds have high melting and boiling point. 3. Elements of group1,2,3 generally form cations. |
|
Answer» :1) As we move from lithium to potassium or simply moving down in a group size increses, it is because of addition of shells. 2) Ionic compounds have high melting and boiling point because there bonds are TIGHTLY packed. and we've to do more work to break bonds between them. So, GENERALLY ionic compounds have high melting as well as high boiling point. 3) Elements of group 1,2,3 are generally cations because they have additional electrons in their outermost SHELL. So, they donate electrons to electronegative atoms therefore a charge is DEVELOPED on them. This is reason why they are cations. |

in a compound carbon and oxygen react in ratio of 3 is to 8 by mass to form carbon dioxide what mass of oxygen is required to react completely with 9 gram of carbon |
|
Answer» tion:Carbon and oxygen combine together to FORM co2 The ratio of their COMBINATION is 3:8 Now, Let the MASS be x So, The ratio of the combination will be 3x: 8x Now, Mass of oxygen is given as 32 GRAMS So, 8x = 32 Or, x = 32/8 = 4 grams So, The mass of carbon to react with 32 grams of oxygen is 3x So, 3x = 3*4 Or, 3x = 12 grams Therefore, 12 grams of carbon will react completely with 32 grams of oxygen. |
