The answer would be 3.55 x 10^3 j/mol
Answer:
1-b
2-weaker(option is incorrect)
3-a
Explanation:
1-b because iodine is more electronegative because of this negative on iodine will be more stable as negative charge on more electronegative element is more stable.
2-weaker as size of Te (Tellurium) is greater than S (sulphur) so bond length of H-Te is larger than H-S and therefore bond energy will be lesser and can easily give hydrogen in case of H-Te. as bond energy is inversly proportional to bond length.
3-a hydrogen has more negative electron affinity so hydrogen will have -1 charge and it will behave as a electron donar atom that is basic not acidic hence NaH is not acidic.
Any kind of pull or push is a force. In order to illustrate a force, one must be familiar with two things. One must be familiar with the direction of the force and the size of the force. The forces, which are equivalent in size but in opposite direction are known as the balanced forces.
The balanced forces do not result in a change in motion. When the balanced forces function on an object at rest, the object will not move. The forces, which results in a change in the motion of an object are known as the unbalanced forces. The unbalanced forces are not opposite and equal.
Answer:
liquid bolling
Explanation:
because it just using heat.
During all chemical reactions, the mass of the products is never equal to the mass of the reactants.
- FALSE
Mass is sometimes lost in chemical reactions.
- FALSE
The Law of Conservation of Mass states that mass is not conserved.
- FALSE
