Since the atoms or molecules in a solid do not translate hence, the structures of solids usually described in terms of the positions of the constituent atoms rather than their motion.
<h3>States of matter</h3>
There are three state of matter which are;
In a solid, atoms or molecules retain their positions and do not translate, hence, the structure of atoms or molecules are most important in determining the structure of a solid.
Also, the fact that the atoms or molecules in a solid can only vibrate or rotate explains why the structures of solids usually described in terms of the positions of the constituent atoms rather than their motion.

False
Because " like dissolve like " polar solute dissolve in polar solvent and vice versa
Answer:
749 grams CO₂
Explanation:
To find the amount of carbon dioxide produced, you need to (1) convert grams C₃H₈ to moles C₃H₈ (via molar mass from periodic table), then (2) convert moles C₃H₈ to moles CO₂ (via mole-to-mole ratio via reaction coefficients), and then (3) convert moles CO₂ to grams CO₂ (via molar mass from periodic table). It is important to arrange the ratios/conversions in a way that allows for the cancellation of units. The desired unit should be in the numerator. The final answer should have 3 significant figures because the given value (250. grams) has 3 sig figs.
Molar Mass (C₃H₈): 3(12.01 g/mol) + 8(1.008 g/mol)
Molar Mass (C₃H₈): 44.094 g/mol
1 C₃H₈ + 5 O₂ ---> 3 CO₂ + 4 H₂O
Molar Mass (CO₂): 12.01 g/mol + 2(16.00 g/mol)
Molar Mass (CO₂): 44.01 g/mol
250. g C₃H₈ 1 mole C₃H₈ 3 moles CO₂ 44.01 g
------------------ x ---------------------- x ---------------------- x -------------------- =
44.094 g 1 mole C₃H₈ 1 mole CO₂
= 749 grams CO₂
Answer:
