An unstable nucleus loses the most mass if the nucleus emits(1) an alpha particle (3) a positron
(2) a beta particle (4) a gamma ray

Answers

Answer 1

Answer: The correct answer is option 1. An unstable nucleus loses the most mass if the nucleus emits an alpha particle. This type of electromagnetic radiation has the largest mass among the radioactive particles. When this particle is emitted from a nucleus, it loses two protons and two neutrons therefore large amount of mass is lost.

Describe the difference between polar covalent bonds and nonpolar covalent bonds using these two molecules - H2 and HCl. Which molecule contains a polar covalent bond and which molecule contains a nonpolar covalent bond? Explain your reasoning alongside describing the differences between the types of bonds.

Answers

Polar covalent bonds are between atoms with different electronegativities, whereas nonpolar covalent bonds are between atoms with the same electronegativity.

This means that HCl is a polar covalent bond, whereas H2 is a nonpolar covalent bond.

You discover a new type of gland associated with the skin. chemical analysis of the product shows a secretion has a ph of 4, consists of 99% water, and contains traces of normal electrolytes including urea, vitamin c, and dermicidin. there are no traces of fats or proteins. how would you classify this new gland?

Answers

This new gland would most likely be an eccrine gland, meaning it would be a sweat gland. They are found all over the body and can also be called merocrine glands.

This new gland would most likely be an eccrine gland, meaning it would be a sweat gland.
They are found all over the body and can also be called merocrine glands.

Explanation:
The 2 main forms of sweat glands are eccrine sweat glands and apocrine sweat glands.

Eccrine sweat glands are smaller sweat glands. they're volute cannular glands that discharge their secretions onto the surface of the skin sweat gland.
any of the rather tiny secreter that manufactures a fluid secretion while not removing protoplasm from the secreting cells which are restricted to the human skin is called eccrine sweat gland.

Which makes the phosphorus cycle different from the carbon cycles

Answers

The phosphorus cycle is different compared to the water,carbon, and nitrogen cycle because it can not be found in the gas state. Phosphorus is only found in land, water, and sediment. The phosphorus cycle is a bio-geochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere. The other cycles is the process by which it is converted between its various chemical form. Phosphorus has small particles that only sometime go up into the atmosphere and contribute to acid rain but other than that phosphorus stays in and on land, sea, and sediment.(:
