Answer:
Vanderwaals forces
Explanation:
CBr4 is a nonpolar molecule, nonpolar molecules usually possess vanderwaals forces between their molecules as their main attractive force.
CBr4 is nonpolar because the tetrahedral arrangement of the C-Br bonds cancel out the individual dipole moments of each C-Br bond thereby making the compound nonpolar, hence the answer above.
Answer:
The vertical columns (group) of the periodic table are arranged such that all it's elements have the same number of valence electrons. All elements within a certain group thus group share similar properties.
Answer:
The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body's tissues.

Answer:
b) Baking soda
Explanation:
Baking soda is sodium hydrogen carbonate, NaHCO₃.
It reacts with water according to the equation
NaHCO₃ + H₂O ⇌ H₂CO₃ + NaOH
Thus, baking soda is a base because it increases the concentration of hydroxide ions in water.
<em>Water</em> is <em>neutral</em>.
<em>Lemon juice</em> is an <em>acid</em> because it contains citric acid.
An <em>insulator </em>is a substance that does not conduct electricity. Insulators are <em>neither acidic nor basic</em>.
Ok, so the circulatory system in plants and animals is like a method of transport. Both plants and animals use this to transport waste and nutrition.
