An Ionic bond is when you have a metal and a nonmetal element bonded together. In this kind of bonds, the metal atom takes electrons from the nonmetal. on other words, this bond involves the gaining and losing of electrons. The atom that receives the electrons becomes an anion (negatively charged ion) and the one that loses them becomes the cation (positively charged ion)
A covalent bond is a bond created between two nonmetals element. In here, both atoms share the electrons.
Both bonds involve interaction between atoms.
Total weight = 1 + 35.45 + 3 * 16 = 84.45
H = 1 / 84.45 * 100% = 1.18%
Cl = 35.45 / 84.45 * 100% = 41.98%
O = 48 / 84.45 * 100% = 56.84%
The answer for the question above is A. the gravitational pull of the moon on the water near the coast. The sun and and the moon are responsible for the rising and falling of the ocean tides. The gravitational pull of the moon and the sun makes the water in the oceans bulge, causing a continuous change between high and low tide.
Answer:
it identifies reducing sugars (monosaccharide's and some disaccharides), which have free ketone or aldehyde functional group
Explanation:
It turns from turquoise to yellow or orange when it reacts with reducing sugars.
Answer:
Mass = 9.8 g
Explanation:
Given data:
Molarity of solution = 0.2 M
Volume of solution = 500 mL
Number of grams of phosphoric acid = ?
Solution:
First of all we will convert the volume milliliter to litter.
500 mL × 1 L/1000 mL
0.5 L
Molarity = moles of solute / volume in litter
0.2 M = number of moles / volume in litter
Number of moles = 0.2 mol/L × 0.5 L
Number of moles = 0.1 mol
Number of grams:
Number of moles = mass/molar mass
Mass = number of moles × molar mass
Mass = 0.1 mol × 98 g/mol
Mass = 9.8 g
