Answer:
14.None would shine if bulb 1 broke
Explanation:
Bulb one connects all the other bulbs to the switch. If bulb 2 broke instead only 1 and 3 will shine because bulb 2 is not connected to bulb 3. all the bulbs should light when the switch is on.
I dont think I actually got this right pls dont take my answer for fact.
Answer:
Percent yield = 7.1%
Explanation:
The general reaction of the problem is:
Ca(OH)₂ + CO₂ → H₂O + CaCO₃
To solve this question we need to find theoretical yield using the amount of carbon dioxide added because:
Percent yield = Actual yield (3.22g) / Theoretical yield * 100
Theoretical yield is the maximum amount of product that could be obtained. To find it we need to convert the mass of CO₂ to moles. The moles of CO₂ = Moles of CaCO₃:
<em>Moles CO₂ -Molar mass: 44.01g/mol):</em>
20.0g * (1mol / 44.01g) = 0.454 moles CO₂ = Moles of CaCO₃ produced
<em>Mass CaCO₃ = Theoretical yield -Molar mass: 100.09g/mol-:</em>
0.454 moles * (100.09g / mol) = 45.5g of CaCO₃ = Theoretical yield.
Replacing:
Percent yield = 3.22g / 45.5g * 100
<h3>Percent yield = 7.1%</h3>
Answer:
The C14 would be found in Glyceraldehyde-3-Phosphate, and the O18 would also be found in the same molecule
Explanation:
Isotopic labeling is a common method for deducing reaction mechanism in chemistry.
In photosynthesis, the oxygen in the found in Glyceraldehyde-3-Phosphate comes from the carbon dioxide, This is also finally found in the glucose produced at the end of the cycle.
The oxygen in water is released into the atmosphere as the oxygen molecule.
Therefore, the C14 would be found in Glyceraldehyde-3-Phosphate, and the O18 would also be found in the same molecule.
As you move down a group, first ionization energy decreases. Electrons are further from the nucleus and thus easier to remove the outermost one
Answer:
<em><u>Mass (kg) × Acceleration (m/s²) = Force (N)</u></em>
