The correct answer will be C. Carbon and Oxygen because these both are non metals and non metals react colvalently (i.e share electrons) while when metals react with a non metals they react ionically (i.e lose and gain electrons)
Answer:
0.75moles of H₄SiO₄
Explanation:
Given parameters:
Number of moles of H₂O = 1.5moles
Unknown:
Number of moles of H₄SiO₄ = ?
Solution:
To solve this problem, we need to write the reaction equation first;
SiO₂ + 2H₂O → H₄SiO₄
From the balanced reaction equation:
2 moles of water will produce 1 mole of H₄SiO₄
So 1.5 moles of water will produce 
= 0.75moles of H₄SiO₄
The right answer is Hydrogen bonds with the polar end of the phospholipid molecule.
A phospholipid contains a phosphoric acid group as mono or di-ester.
The physicochemical properties of phospholipids depend both on the polar molecule of the hydrophilic head and on the aliphatic chains of the hydrophobic tails. In an aqueous medium, such amphiphilic molecules tend to be organized so that only their hydrophilic head is in contact with the water molecules, which typically results in structures in micelle, liposome or lipid bilayer.
Answer:
water can dissolve ionic and polar molecules.
Answer:
Explanation:
The glass rod losses electrons because the silk cloth has a positive charge so it attracts the negative charge of the glass rod.
