All solids have an orderly internal structure with repeating bonding patterns between atoms, ions, or molecules. They are called crystal lattices. They are a 3-dimensional arrangement of atoms inside a crystal. The volume of this crystal is:
<span>
Volume = 2.44 × 10^–2 m x 1.4 × 10^–3 m x 8.4 × 10^–3 m = </span>2.87 x 10^-7 m^3
Answer:
A safety guide lines are rules and regulations that are made to make sure place is safe and conducive for everyone.
I’m sorry but could you type the questions out? I can’t really see the question
Answer:
I would guess B, because trees make oxygen, not carbon dioxcide, and coal is actually a very harmful source of energy.

Explanation:
Answer:
nNaOH = 0,2 mol
Trong hỗn hợp các chất đề bài cho chỉ có phenol tác dụng với NaOH
C6H5OH + NaOH → C6H5ONa + H2O
0,2 ← 0,2 (mol)
⟹ mphenol = 0,2.94 = 18,8 gam
⟹
%mC6H5OH=18,8/28,9 x100%= 65,05%
