The density of Ca will be between that of Mg and Sr

Explanation:

Ca, Mg and Sr are group II elements. They are called alkali earth metals. The correct order of the elements in this group are: Be, Mg, Ca, Sr, Ba and Ra.

Density is an intensive property of matter which describes the amount of matter(mass) per volume of a substance.

  • Density varies proportionally with mass. The higher the mass, the higher its density.
  • On the periodic table, atomic mass which the number of protons and neutrons in the nucleus of an atom increases down the group.
  • This implies a progradation in the value of density down the group. Therefore one expects that the value of density of Ca will fall between that of Mg and Sr. It cannot be more than 2.6g/cm³ nor less than 1.74g/cm³.

Some chemical reactions releases energy other store energy what important chemical reaction storage energy?
olganol [36]

Answer:

A chemical reaction that stores energy is called an endothermic reaction. More energy might be released as products form than the energy needed to break the reactants apart. This chemical reaction will release energy. In other words, it will be an exothermic reaction.

The correct statements which are true for the reactions in the Sun are that are fusion reactions and reactions occur because of very high temperatures.

<h3>What is nuclear fusion?</h3>

Nuclear fusion reactions are those reactions in which two species reacts with each other for the formation of new specie.

In the core of the sun, nuclear fusion of hydrogen atoms occur for the formation of helium molecules in the presence of high temperature.

Hence, the correct statements are they are fusion reactions and reactions occur because of very high temperatures.
