Hi,
The answer should be ‘soap is a base because it’s pH is above 7’
K₂SO₄ + CaI₂ → CaSO₄ + KI
K: 2 K: 1
S: 1 S: 1
O: 4 O: 4
Ca: 1 Ca: 1
I: 2 I: 1
↓
K₂SO₄ + CaI₂ → CaSO₄ + 2KI
K: 2 K: 2
S: 1 S: 1
O: 4 O: 4
Ca: 1 Ca: 1
I: 2 I: 2
Not A because
2-Pentyne, an organic compound, is an internal alkyne. It is an isomer of 1-pentyne, a terminal alkyne
Is B because
DescriptionPentenes are alkenes with chemical formula C ₅H ₁₀. Each contains one double bond within its molecular structure.
What does the lab say because then i can help :)
Thank you for posting your question here. I hope my answer will help. below are the choices that can be found elsewhere:
a. 300 mi/hr2
<span>b. 61 mi/hr2 </span>
<span>c. 8,201 mi/hr2 </span>
<span>d. 40,500 mi/hr
</span>
Below is the solution:
<span>135 * 135 / 0.450 = 40,500 mi/hr2 </span>
