Which Of The Following Atoms Will Have Themost Similar Properties To The Atom Shownbelow?

Answers

Answer 1
Answer:  Atom IV

Explanation:

Atoms that have the same number of valence electrons (belong to the same group of the periodic table) have similar properties. Hydrogen and Helium are exceptions.  The first shell is filled with 2 electrons which makes Helium a Noble Gas and Hydrogen is a gas thus not a Group 1 metal.

The given atom has 2 valence electrons (a group 2 element).

∴ the atoms with similar properties to that of the given atom would also have 2 valence electrons:

I - filled 1st shell thus noble gas ❌

II - 3 valence electrons ❌

III - 4 valence electrons ❌

IV - 2 valence electrons ✅

∴ atom IV has similar properties to the given atom.

Checking my answer:

If we check the periodic table, the atom given is Be (Alkali Earth Metal)

I is He  (Noble Gas)

II is Bo (Group 13)

III is C (Group 14)

IV is Magnesium (Alkali Earth Metal)

QUICK!! 2NaN3 —> 2Na + 3N2

this equation is balanced, but why does the N in the reactant have a subscript of 3, and the N in the product has a subscript of 2.

why did the subscript change? from what i learnt, when you balance an equation, you can only use coefficients to balance the equation.

Answers

Answer:

-Before balancing the equation, you need to determine the index of the components in the substances correctly to balance

Is diphenylmenthane a solid or liquid at room temperature

Answers

Answer:

diphenylmethane is liquid at room temperature.

Explanation:

It is a solid below room temperature and its melting point is at 22 degree celsius to 24 Celsius degree celsius.

Diphenylmethane is a solid at room temperature. Diphenylmethane is a non-polar compound.

Diphenylmethane is a colorless, crystalline solid with a melting point of 53 °C. It is a member of the diphenylmethanes, which are a class of organic compounds that contain two benzene rings joined by a single carbon-carbon bond.

Diphenylmethane is a non-polar compound, which means that it does not have any permanent dipole moments. This makes it difficult for the molecules of diphenylmethane to interact with each other, which is why it is a solid at room temperature.

If diphenylmethane were a polar compound, the molecules would be able to interact with each other through dipole-dipole interactions. This would make the compound more likely to be a liquid at room temperature.

give reason : Inert gas shows least reactivity
pls help

Answers

Answer:

Noble gases also known as inert gases are the least reactive of all known elements because with eight valence electrons, their outer energy levels are full. As a result, noble gases cannot become more stable by reacting with other elements and gaining or losing valence electrons. Therefore, noble gases are rarely involved in chemical reactions and almost never form compounds with other elements.

Explanation:

The only exception is helium, which has just two electrons. But helium also has a full outer energy level, because its only energy level (energy level 1) can hold a maximum of two electrons. A full outer energy level is the most stable arrangement of electrons.

Monterey Bay, on the California coast, contains a diverse and complex ecological community. A variety of seaweeds and single-celled algae make up the base of the food web. Many animals, such as sea urchins, abalone, snails, and crabs, graze on these photosynthetic organisms. Otters and small fish eat all of these primary consumers and in turn are eaten by orcas and sharks. Orcas eat many other smaller organisms, including dolphins, sea lions, harbor seals, and many kinds of fish. Sea stars prey on sea urchins, abalone, and snails, whereas octopus eat crabs, fish, and sea stars. Sea lions and harbor seals eat predominantly fish. Sea cucumbers eat dead organic matter that falls to the sea floor. Place each of the organisms in the trophic pyramid based on where it gets its energy. Each organism will be used only once even if some of the organisms consume organisms from several trophic levels. Place organisms that eat from several trophic levels at the highest possible trophic level.
