Answer:
In solids, the atoms are tightly packed together. In gases, atoms are spread out.
Explanation:
Hey there!
Consider 100 g of solution:
Mass of NaCl = 3.50% of mass of seawater
( 3.50 / 100 ) * 100 => 3.50 g
Number of moles as shown below:
Molar mass NaCl = 58.44 g/mol
n = Mass / molar mass
n = 3.50 / 58.44 => 0.059 moles of NaCl
Mass of sweater:
Mass of solution - Mass of NaCl
100 - 3.50 = 96.5 g
96.5 g in Kg :
96.5 / 1000 => 0.0965 Kg
Therefore ,calculate molality by using the following formula:
molality = number of moles of solute / mass of solution
molality = 0.059 / 0.0965
molality = 0.61 m
Hope That helps!
The products : Zn₃(PO₄)₂ (s) + KClO₃ (aq)
<h3>Further explanation</h3>
Given
reaction: Zn(ClO₃)₂ (aq) + K₃PO₄ (aq)
Required
The products
Solution
Double-Replacement reactions : an ion exchange between two ion compounds in the reactant to form two new ion compounds in the product
General formula :
AB + CD ⇒ AD + CB
One of the characteristics of the double replacement reaction is the presence of precipitated compounds
Zn(ClO₃)₂ (aq) + K₃PO₄ (aq) ⇒ Zn₃(PO₄)₂ (s) + KClO₃ (aq)
Zn₃(PO₄)₂ (s)⇒ precipitated compounds, so that this reaction can occur
The answer would be C.) clay The wax can turn really hard and can be unbreakable when present in colder materials due to the lipids present in it. Clay however can become a mold because of its low melting point.
Answer:
I disagree, because earth rotation on its axis causes day and night, on the other hand the its revolution on the orbit around the sun causes seasons. One Rotation would means one day has completed, and one revolution would mean that one year has completed. Therefore, it's obvious that Earth's revolution takes longer than the rotation.
I hope that helps...
