60% c 8% H and the 300g and molecular formula = 68% and 300g
Answer:
- The condensation reaction that forms nucleic acid polymers occurs between a <u><em>Phosphate</em></u> group on one nucleotide and a <u><em>hydroxyl group of sugar</em></u> on a second nucleotide.
Explanation:
- When nucleotides polymerize to form nucleic acids, the hydroxyl group attached to the 3′ carbon of a sugar of one nucleotide forms an ester bond to the phosphate of another nucleotide, eliminating a molecule of water.
Summary:
So the phosphate group of one nucleotide form bond with the hydroxyl group of an other nucleotide with the elimination of water molecules.
The correct answer is Gallium.
The largest temperature range for the liquid state of an element is Gallium
What Is Gallium?
A chemical element called gallium has an atomic mass of 69.72 g.mol^-1. Gallium has an atomic number of 31. In general, gallium is thought to be a soft metal under normal pressure and temperature. Ga stands for gallium.
Properties of Gallium
- A soft metal with an extremely glossy surface is gallium. The color of pure gallium is somewhat silver-blue. Gallium does not exist in its elemental or natural form in the natural world. It must be removed through smelting or some other process. It is incredibly distinct and doesn't resemble metal at all. It is pliable and a knife can be used to cut it.
- It has a relatively low melting point of roughly 29 degrees Celsius. As a result, if your body temperature is higher than 30 degrees Celsius, a portion of it may likely melt in your hands. It is one of the four non-radioactive chemical elements that are liquid at ambient temperature, along with mercury, rubidium, and cesium. Gallium readily adheres to porcelain or glass.

Answer:
It is valid because his experiment had clear variables.
Explanation:
He had clear variables and did everyhting the same for both plants, even though he had calcium in one and not in the other, which gives him a true and good result.
