H2O (water) is a compound molecule.

Ca, Na, Mg are elemental metals.

NB

When writing elemental symbols;-

  1. Single letter symbols are always a CAPITAL letter e.g. 'O' oxygen.

  2. Double letter symbols are always written as , first letter is a capital letter and the second letter is lower/small case. e.g. 'Ca'( Calcium). Na(Sodium) , & Mg (Magnesium).

NOT as given with all capital letters.

What is most similar to calcium K Sc Mg Na?

Among the options listed, magnesium (Mg) is most similar to calcium (Ca) in terms of properties and roles in biological systems. Both are alkaline earth metals found in group 2 of the periodic table and play essential roles in maintaining proper function of muscles, nerves, and bones. Potassium (K), sodium (Na), and scandium (Sc) belong to different groups of the periodic table and have distinct properties compared to calcium.


What are the three main types of magma and what factor determines these classifications?

The three main types of magma are basaltic magma, andesitic magma, and rhyolitic magma. They are classified according to their mineral composition. Basaltic magma is composed of SiO2 45-55 wt%, high in Fe, Mg, Ca, low in K, Na. Andesitic magma is composed of SiO2 55-65 wt%, intermediate. in Fe, Mg, Ca, Na, K. Rhyolitic magma is composed of SiO2 65-75%, low in Fe, Mg, Ca, high in K, Na.


S na cl mg witch one is largest?

Magnesium (Mg) is the largest atom among sulfur (S), sodium (Na), chlorine (Cl), and magnesium (Mg). This is because the size of an atom increases as you move down a group in the periodic table. Magnesium is located below the other elements in the periodic table, making it the largest atom among these options.

What is the equation for the reaction of magnesium ions and sodium stearate?

The reaction between magnesium ions and sodium stearate would involve the magnesium ion (Mg^2+) displacing sodium (Na^+) in sodium stearate to form magnesium stearate and sodium ions. The equation can be represented as Mg^2+ + 2(C_17H_35COO^−) → Mg(C_17H_35COO)_2 + 2Na^+.
