Adhesion-attraction amoung molecules of a different substance.
Cohesion-attraction amoung molecules in a substance
Hydrogen Bonding- a bond between an hydrogen atom and a negative atom
Polar- difference of charge across the molecule
Answer:
spring tide
Explanation:
When the sun, moon, and Earth are in alignment (at the time of the new or full moon), the solar tide has an additive effect on the lunar tide, creating extra-high high tides, and very low, low tides — both commonly called spring tide
In the given equations for chemical reaction, The Equation No. 2 represents an endothermic chemical reaction.
<h3>What is an Endothermic Chemical Reaction ?</h3>

The gram formula mass is another term for the mass of one mole of the substance which can be calculated by adding up the masses of the elements comprising the formula unit, molecules, etc.
a. Barium Fluoride (BaF2)
m = mass of Ba + 2(mass of F)
m = 137.327 g + 2(19 g)
m = 175.327 g
b. Strontium Cyanide (Sr(CN)2)
m = mass of Sr + 2(mass of C) + 2(mass of N)
m = 87.62 + 2(12) + 2(14)
m = 139.62 g
c. Sodium hydrogen Carbonate (NaHCO3)
m = mass of Na + mass of H + mass of C + 3(mass of O)
m = 23 + 1 + 12 + 3(16)
m = 84 g
d. Aluminum sulfide (Al2S3)
m = 2(mass of Al) + 3(mass of S)
m = 2(26.98) + 3(32)
m = 149.96 g
