Answer:
64.15 mL.
Explanation:
- We can use the general law of ideal gas: <em>PV = nRT.</em>
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
- If n and P are constant, and have two different values of V and T:
<em>V₁T₂ = V₂T₁</em>
<em></em>
V₁ = 65.0 mL, T₁ = 92.4°C + 273 = 365.4 K.
V₂ = ??? mL, T₂ = 87.6°C + 273 = 360.6 K.
<em>∴ V₂ = V₁T₂/T₁</em> = (65.0 mL)(360.6 K)/(365.4 K) = <em>64.15 mL.</em>
Answer is: Rutherford demonstrate that <span>J.J Thompson's Plum Pudding model was not accurate.
</span><span>Rutherford theorized
that atoms have their charge concentrated in a very small nucleus.
</span>This was famous
Rutherford's Gold Foil Experiment: he bombarded thin foil of gold
with positive alpha particles (helium atom particles, consist of two protons and two neutrons).
Rutherford observed the
deflection of alpha particles on the photographic film and notice that most of alpha particles passed straight through foil.
That is different from Plum Pudding model<span>, because it shows that most of the atom is empty space.</span><span>

It is Titanium (II) Phosphate.
The zinc ion +1 can exist but it is very rare and not likely to show up on school work but in your case it did how odd
Answer:
d. the conjugate base.
Explanation:
The general reaction of a weak acid, HA, with a strong base YOH, is:
HA + YOH → A⁻ + H₂O + Y⁻
<em>Where A⁻ is the conjugate base of the weak acid and Y⁻ usually is a strong electrolyte.</em>
<em />
That means after he complete reaction you don't have weak acid nor strong base, just conjugate base that will be in equilibrium with water, thus (Strong electrolyte doesn't change pH:
A⁻ + H₂O ⇄ HA + OH⁻
As the equilibrium is producing OH⁻, the pH of the solution is being affected for the conjugate base
Right option:
<h3>d. the conjugate base.
