They have the same number of electrons in their outer shells. Elements in the same group often share similar chemical properties because the outer electrons generally determine a lot of their properties
Answer: Ammonia (NH3) and sodium carbonate (Na2CO3), because they accept hydrogen ions but lack hydroxide ions.

i took the test and got it correct :) hope this helps
Volume of CO₂ obtained : 13 L
<h3>Further explanation</h3>
Reaction
C₂H₅OH + 3 O₂ ⇒ 2 CO₂ + 3 H₂0 + 8842 Joules
moles of ethanol=0.28
From equation, mol ratio ethanol : CO₂ = 1 : 2, so mol CO₂ :
Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.
Then volume of CO₂ :

<span>Titanium is the first element in the fourth column of the periodic table. It is classified as a transition metal. Titanium atoms have 22 electrons and 22 protons. Titanium is fairly inactive and is very resistant to corrosion from other elements and substances like acids and oxygen. It has a relatively low electrical and thermal conductivity. Titanium is used to alloy with different metals such as iron, aluminum, and manganese where it helps to produce strong and lightweight alloys for use in spacecraft, naval ships, missiles, and as armor plating.</span>
