What does the group number of element 114 have to do with its stability?

Chemistry
1 answer:
zhenek [66]3 years ago
8 0

Answer:

Super-heavy elements like 114 usually only exist for fractions of a second. ... The physicists called these magic numbers the “island of stability”, because the elements with the numbers cluster together on the periodic table, flanked on all sides by ephemeral elements that dissipate in nanoseconds.

Hydrazine, N2H4, may react with oxygen to form nitrogen gas and water.
Sindrei [870]

Answer:

The percent yield of the reaction is 35 %

Explanation:

In the reaction, 1 mol of hydrazine reacts with 1 mol O₂ to produce 1 mol of nitrogen and 2 moles of water.

Let's verify the moles that were used in the reaction.

2.05 g . 1mol/ 32 g = 0.0640 mol

In the 100% yield, 1 mol of hydrazine produce 1 mol of N₂ so If I used 0.0640 moles of reactant, I made 0.0640 moles of products.

Let's use the Ideal Gases Law equation to find out the real moles of nitrogen, I made (real yield).

1atm . 0.550L = n . 0.082 . 295K

(1atm . 0.550L) / 0.082 . 295K = n → 0.0225 moles

Percent yield of reaction = (Real yield / Theoretical yield) . 100

(0.0225 / 0.0640) . 100 = 35%

How do scientists believe that chloroplasts got into photosynthetic cells? ​
Lera25 [3.4K]

The development of chloroplast is thought to occur through endosymbiosis.

According to the endosymbiosis, some of the organelles found in modern eukaryotic cells, such as mitochondria and chloroplasts, were previously prokaryotic microorganisms. A non-photosynthetic creature acquired one photosynthetic cell, and the chloroplast was subsequently created.

An organelle known as a chloroplast is crucial to the process of photosynthesis in plants. It contains pigments like chlorophyll and other  pigments that are in charge of capturing sunlight. Since each chloroplast has two membranes, other organelles such as mitochondria are referred to as double-membrane organelles. It is believed that cyanobacterial endosymbiosis played a role in the genesis of the chloroplast. Prokaryotic organisms like cyanobacteria have the capacity to prepare their food through the process of photosynthesis.
