The first student treats the starting material which is the 3-oxobutanoic acid with sodium methoxide which is followed by methyl iodide and form compound A. Analysis 1HNMR it shows that this is not the desired material.
Compound A has same 2-methyl-3- oxobutanoate acid as molecular formula.
Explanation:
the answer is letter A. mitosis
Answer:
Invasive species, runoff pollution, and climate change.
Explanation:
Invasive species, such as Burmese pythons, threaten the Florida Everglades because they are not native to the natural habitat. Pythons eat the native animals, but they don't have any predators.
Pollution from nearby farms and roads enters the water and damages the ecosystem of the Everglades and Louisiana wetlands. Toxic chemicals lead to detrimental effects for both humans and wildlife.
Humans have drained swampy areas to allow for development. However, this has led to the Everglades drying up and even burning in recent years.
The events that occur is based on the type of hormone being released. Like puberty. It's an event coming from different types of hormones being sent to a tissue
The molarity of a Sodium carbonate solution : 0.373 M
<h3>Further explanation</h3>
Given
32.52 g Na₂CO₃
822 ml of solution = 0.822 L
Required
The molarity
Solution
Molarity shows the number of moles of solute in every 1 liter of solution.
mol of solute = mol of Na₂CO₃ :
= mass : MW Na₂CO₃
= 32.52 g : 106 g/mol
= 0.307
Molarity :
= n : V
= 0.307 mol : 0.822 L
= 0.373 M
