Oduvanchick [21]
If you add a surfactant in water-oil mixture, surfactant molecules would form micelles wherein the hydrophobic end of the surfactant faces inside the micelle while the hydrophilic end faces the water molecules. Inside these micelles oil particles are attached.

Vedmedyk [2.9K]

Answer:

317.7778 g

Explanation:

Given data:

Flour required for 18 cup cakes = 260 g

Flour required for 22 cup cakes = ?

Solution:

We will calculate the flour required for 1 cup cake.

260 g /18   = 14.4444 g

Fluor required for 22 cupcakes,

22× 14.4444 g = 317.7778 g

In short,

22 cupcake/18 cup cake×260 g = 317.7778 g

Read the false statement. Atoms of elements with one valence electron form anions in order to meet the octet rule. Which answer
Zepler [3.9K]

Answer:

C. Atoms of elements with five to seven valence electrons form anions in order to meet the octet rule.

Explanation:

  • Atoms of elements gain or lose electron(s) to obey the octet rule by forming cations or anions.
  • Atoms with 1 to 3 valence electrons lose electrons to form cations in order to attain a stable configuration.
  • Atoms with 5 to 7 valence electrons gain electron(s) to form anions in order to attain stable configuration.
  • However, atoms with 8 valence electrons do not require to gain or lose electrons since they an octet configuration.
  • Atoms of metallic elements such as those in group 1 and 2 lose electron(s) to form cations while atoms of non-metallic elements such as halogens require to gain electron(s) to form anions so as to obey the octet rule.
