The answer is D. Europa Clipper
<u>Answer:</u>
He should have put the glass in a broken glass bin
<u>Explanation:</u>
Putting broken glasses in the trash can or the dust bin can be hazardous to the workers working at local recycling center as the pieces might hurt them. Instead, he should have thrown the broken beaker in a separate glass bin or should have wrapped properly in paper so that it won't hurt anyone.
Also, glasses have a high melting point and therefore it is not recyclable. Hence, it should be trashed separately.
Answer:
P = 995.6 atm
Explanation:
assuming ideal gas:
∴ Tst = 25°C ≅ 298 K
∴ V = 35.00 mL = 0.035 L
∴ molar mass CO2 = 44.01 g/mol
∴ mass CO2(g) = 62.76 g
⇒ mol CO2(g) = (62.76 g)*(mol/44.01 g) = 1.426 mol
∴ R = 0.082 atm.L/K.mol
⇒ P = RTn/V
⇒ P = ((0.082 atm.L/K.mol)*(298 K)*(1.426 mol)) / (0.035 L)
⇒ P = 995.6 atm
I'm pretty sure it would be -87,036
A solution prepared by dissolving 0.0084 moles of HCl in 1500 mL of solution has a Molarity of HCl of 5.6 × 10⁻³ M, a Molarity of H₃O⁺ of 5.6 × 10⁻³ M and a pH of 2.3.
<h3>What is Molarity ?</h3>
- Molarity (M) is the amount of a substance in a certain volume of solution.
- Molarity is defined as the moles of a solute per liters of a solution.
- Molarity is also known as the molar concentration of a solution
A solution is prepared by dissolving 0.0084 moles of HCl in 1500 mL of solution. The molarity of HCl is:
[HCl] = 0.0084 moles / 1.5 L
= 5.6 × 10⁻³ M
HCl is a strong acid according to the following equation.
HCl(aq) + H₂O(l) ⇒ Cl⁻(aq) + H₃O⁺(aq)
Thus, the concentration of H₃O⁺ will be equal to the initial concentration of HCl, 5.6 × 10⁻³ M.
Now, we will calculate the pH of the solution using its Formula ;
pH = - log[H₃O⁺]
= - log [5.6 × 10⁻³]
= 2.3
Hence, A solution prepared by dissolving 0.0084 moles of HCl in 1500 mL of solution has a Molarity of HCl of 5.6 × 10⁻³ M, a Molarity of H₃O⁺ of 5.6 × 10⁻³ M and a pH of 2.3.
