Answer:
Density stays the same
Explanation:
The density remains the same because cutting the object in half will divide the mass & volume by the same amount. Also, the density of a substance remains the same no matter what size it is.
If you have an aqueous solution that contains 1.5 moles of HCl, the number of moles of ions in the solution is 3.0 moles.
<h2>Further Explanation
</h2><h3>Strong acids </h3>
- Strong acids are types of acids that undergo complete dissociation to form ions when dissolved in water.
- Examples of such acids are, HCl, H2SO4 and HNO3
- Dissociation of HCl
HCl + H₂O ⇔ H₃O⁺ + OH⁻
<h3>Weak acids </h3>
- Weak acids are types of acids that undergo incomplete dissociation to form ions when dissolved in water.
- Examples of such acids are acetic acids and formic acids.
- Dissociation of acetic acid
H₃COOH ⇔ CH₃COO⁻ + H⁺; CH₃COO⁻ is a conjugate base of acetic acid.
<h3>In this case;</h3>
- HCl which is a strong acid that ionizes completely according to the equation;
HCl + H₂O ⇔ H₃O⁺ + OH⁻
- From the equation, 1 mole of HCl produces 1 mole of H₃O⁺ ions and 1 mole of OH⁻ ions.
Therefore;
1.5 moles of HCl will produce;
= 1.5 moles of H₃O⁺ ions and 1.5 moles of OH⁻ ions.
This gives a total number ions of;
= 1.5 + 1.5
= 3 moles of ions

Answer:
a) 68.9 b/ ft²
b) 57.416
Explanation:
Volume of the cylindrical open container V = 5 gal
= (5)(231)
= 11155 in³
different diagrammatic expression has been shown in the attached file below for clear understanding.
Area A = 120 in²
V = hA
= 
= 9.625 in
Upward acceleration , 
= 68.9 b/ ft²
b) The flowchart for the resultant force is shown in the diagram below:
with that:
Thus, the resultant force that the container exert on the floor of the elevator during this acceleration = 57.416
Answer:
An element is a substance that is made up of the same kind of atoms and
cannot be broken down into simpler substances by any known chemical means
examples of element are iron boron carbon helium calcium hydrogen etc
Well a mixture is less permanent and also it can be easily taken aprt where a compound does the opposite of those things.
Hope I helped :)
