Answer:
Alkaline earth metals
Explanation:
Group 2 has 2 valence electrons that they lose when being ionized, thus making their charge 2+.
Answer:
The coefficients are 1, 3, 1, 3
Explanation:
The equation;
AlCl3 + NaOH → Al(OH)3 + NaCl
can be balanced by using the coefficients 1, 3, 1, 3, such that the balanced equation will be;
AlCl3 + 3NaOH → Al(OH)3 + 3NaCl
Chemical equations needs to be balanced so as to follow the law of conservation of mass. This occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side.
Answer:
The main purpose of the expedition was to conduct a hydrographic survey of the coasts of the southern part of South America.
Answer:
Thanks! :) Have a great day!
Explanation:
As the period number increases on the periodic table, moving from top to bottom, the atomic radius of the elements increases as well.
