Answer: C (Sugar's tendency to dissolve in water)
Answer:
a. KCl, c. BaCl2 and e. LiF.
Explanation:
Hello,
In this case, we can identify the ionic compounds by verifying the difference in the electronegativity between the bonding compounds when it is 1.7 or more (otherwise it is covalent) as shown below:
a. KCl: 3.0-0.9=2.1 -> Ionic.
b. C2H4: 2.5-2.1=0.4 -> Covalent.
c. BaCl2: 3.0-0.8=2.2 -> Ionic.
d. SiCl4: 3.0-1.8=1.2 -> Covalent.
e. LiF: 4.0-1.0=3.0 -> Ionic.
Therefore, ionic compounds are a. KCl, c. BaCl2 and e. LiF.
Regards.
Answer: A) inherited traits
Explanation: theses are all traits that plants can inherit from its parents
Answer:
129,66 g
Explanation:
Desde,
Número de moles = concentración * volumen
concentración = 2 M
volumen = 875 ml
Número de lunares = 2 * 875/1000
Número de lunares = 1,75 moles
Número de moles = masa / masa molar
masa molar de hidróxido de calcio = 74.093 g / mol
1,75 moles = masa / 74,093 g / mol
masa = 1,75 moles * 74,093 g / mol
masa = 129,66 g
