Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.
<span> the equation for helium could be: D + T -> He + n. D is deuterium (H-2), T is tritium (H-3), and n symbolizes a neutron.</span>
HCl + NaOH -> NaCl + H2O
reactants: hydrochloric acid HCl
sodium hydroxide NaOh
products: sodium chloride (table salt) NaCl
dihydrogen monoxide (water)
H2O
<span>When BaCrO4 dissolves, it dissociates like this: BaCrO4 (s) --> Ba2+ + CrO42-
</span>
<span>The expression for Ksp is [Ba2+] x [CrO42-]
</span>
There is a 1:1 molar ratio between the BaCrO4 that dissolves and Ba2+ and CrO42-
that are in solution. This means that, when 1.08×10⁻⁵ moles per liter of BaCrO4 dissolves, it produces 1.08×10⁻⁵ mol/L of Ba2+ and 1.08×10⁻⁵ of <span>CrO42-. So, applying the expression:
</span>
Ksp = (1.08×10⁻⁵ ) x (1.08×10⁻⁵ )
= 1.166 x 10⁻¹⁰
Answer:
.562 mol (with respect to signifigant figures)
Explanation:
to find moles we must use concentration to cancel liters.
2.250 mol/L x .250 L = .5625 mol
Uhm I think 5 sorry if I’m wrong
