When comparing single bonds between atoms of comparable types, the stronger the bond is, the bigger the atom, the weaker it is.
The length of the X-H bond lengthens while the strength of the bond shortens with increasing halogen size (F-H strongest, I-H weakest). When comparing single bonds between atoms of similar sorts, the larger the atom, the weaker the bond. It can be explained by the fact that less energy is required to break the bond the bigger the atom's atomic size. The force of attraction from the nucleus to the outermost orbit will be less for iodine since it has a larger atom than the other elements in the group.

an ionized gas consisting of positive ions and free electrons in proportions resulting in more or less no overall electric charge, typically at low pressures (as in the upper atmosphere and in fluorescent lamps) or at very high temperatures (as in stars and nuclear fusion reactors).

Answer:
True
Explanation:
The complete question is:
<u><em>"A reaction contains two reactants, A and B. If A is doubled, there will be a greater number of effective collisions between reactants. TRUE FALSE"</em></u>
Collision Theory indicates that chemical reactions take place because molecules, atoms or ions collide with each other.
Furthermore, the molecules must collide effectively, that is, not all reagent collisions lead to product formation. Effective shock means that the reagent molecules have enough kinetic energy at the time of the shock for their bonds to break and product bonds to form. In addition, the molecules of the reagents must be properly oriented for the reaction to take place.
As the concentration increases, the number of shocks increases. In other words, by increasing the concentration of the reactants, the probability of collision between their molecules increases, and therefore the number of effective collisions.So the statement is true-
Answer:
An exothermic combination reaction
Explanation:
There are two aspects to consider regarding this reaction, as it doesn't only provide the reaction but it also includes the enthalpy change for the reaction.
In terms of this reaction, magnesium atom combines with oxygen molecule to produce one product, magnesium oxide. This may be classified as a combination reaction.
Now, we also see that we released a total of 1199.66 kJ of heat as our product. There are two types of reactions in terms of the enthalpy change: exothermic reactions (those that release heat) and endothermic reactions (those that consume heat).
The enthalpy change for exothermic reactions is negative and it's positive for endothermic reactions.
However, here we're actually given heat as a product. If we have it as a product, this means heat was released into the surrounding by this reaction and we have an exothermic reaction.
