Hello there,
The moment the tablet<span> starts </span>dissolving<span> a chemical reaction occurs that </span>Some<span> factors can change how quickly the carbon dioxide gas is produced. Stir the ice cubes in the jar for about a </span>minute<span> so that the temperature evens out.
</span>
he tablets<span> effervesce, or fizz, when </span>dropped into water. Some<span> factors that influence the speed of a chemical reaction are: (1) Pour the </span>water<span> into 3 separate </span>glass<span> beakers.
</span>
When the solid<span> material has </span>completely<span> disappeared and the bubbles have vaneished. Stir for a </span>minute<span> or two so that it mixes in.
</span>
Hope this helped
Answer: The reaction produces 2.93 g H₂.
M_r: 133.34 2.016
2Al + 6HCl → 2AlCl₃ + 3H₂
Moles of AlCl₃ = 129 g AlCl₃ × (1 mol AlCl₃/133.34 g AlCl₃) = 0.9675 mol AlCl₃
Moles of H₂ = 0.9675 mol AlCl₃ × (3 mol H₂/2 mol AlCl₃) = 1.451 mol H₂
Mass of H₂ = 1.451 mol H₂ × (2.016 g H₂/1 mol H₂) = 2.93 g H₂
Explanation:
I think the answer is C. C and D
