Which elements are metalloids? Check all that apply.boron
tungsten
aluminum
bismuth
silicon
tellurium

Answers

Answer 1
Answer:

Answer:

  • Boron
  • Silicon
  • Tellurium

Explanation:

  • Elements in the periodic table are either metals, non-metals or metalloids.
  • Metals are elements that react by losing electron(s) to attain an octet configuration. They occupy groups I, II and III of the periodic table and the transition metals.
  • Non-metals, on the other hand, are elements that react by gaining electron(s) to attain a stable configuration. Examples include halogens and noble gases among others.
  • Metalloids are elements in the periodic table that have the properties of both metals and non-metals.
  • Other examples of metalloids are arsenic, tellurium, germanium and polonium.

What differs between a radioactive isotope and a stable isotope?A. Stable isotopes are shorter
B. Radioactive Isotopes last for less time
C. Radioactive isotopes last longer.
D. There is no difference

Answers

 A radioactive isotope is emitting particles such as a fast moving electron or positron (radiation) and this is changing its structure. Eventually it may reach a stable configuration and will no longer decay. An stable isotope is simply a name for a form of an element which is chemically identical to other atoms of the element but with a different number of neutrons. I hope this helps!

Radioactive isotopes last for less time, is the one among the following choices given in the question that shows the way a radioactive isotope and a stable isotope differs

Isomers have different ______ formulas. molecular structural empirical chemical

Answers

Answer:

Structural

Explanation:

Isomerism is the existence of two or more compounds with the same molecular formula but different molecular structures due to the difference in the arrangement of atoms or spatial orientation of atoms.

Isomers have the same molecular formula but differs in their structural arrangement.

In organic chemistry, Isomerism can orginate from different arrangement of atoms.

It can be carbon chain length known as chain isomerism. Here, the carbon length is changed and arranged in different ways.

We can also have position isomerism which entails the position of the functional group in the structure.

It can also be functional group isomerism which deals with the possible arrangement of the group on the chain.

Final answer:

Isomers have the same molecular formulas but different structural formulas. This different structural arrangement leads to differences in the physical and chemical properties of the isomers.

Explanation:

Isomers are molecules that have the same molecular formula, meaning the same number and type of atoms, but different arrangements of atoms within the molecule. Hence, isomers have different structural formulas, which are used to represent the three-dimensional arrangement of atoms in a molecule. For instance, the compounds butane and isobutane both have the formula C4H10, but in butane, all four carbon atoms are arranged in a row, while in isobutane, three carbon atoms form a branch off a central carbon atom. Therefore, the structural formulas of these compounds differ, even though the molecular formula is the same.

Which process in the light-dependent reactions results in the release of hydrogen ions, electrons, and oxygen? chemiosmosis
photophosphorylation
water splitting
electron transport

Answers

Answer:

Water spit occurs during release of hydrogen ions,electrons and oxygen.

Explanation:

During  photosynthesis,water is required to be occured.The light activated the chlorophyll during light reactions,This activated chlorophyll molecule will results in splitting of water molecules,as a result water splits into hydrogen,oxygen and electrons.This process is known as photolysis.Hence water splitting occurs during light dependent reactions in release of hydrogen ions,electrons and oxygen.

The answer is actually Water Splitting! Hope this works:D

Which is correct about the Brazil Current and the Gulf Stream?(1 point) A. They occur in different oceans.

B. One carries warm water and another carries cold water.

C. One begins at the equator, and another begins near the South Pole.

D. They travel to different hemispheres.

Answers

Answer:

B. one carries warm water and another carries cold water

The correct answer is B. One carries warm water and another carries cold water.

The Brazil Current and the Gulf Stream are both ocean currents that transport water in different parts of the world. The Brazil Current flows along the eastern coast of South America in the South Atlantic Ocean, while the Gulf Stream flows along the eastern coast of North America in the North Atlantic Ocean.

The Brazil Current carries warm water from the tropics towards the higher latitudes, while the Gulf Stream carries warm water from the Gulf of Mexico towards the North Atlantic. In contrast, the Brazil Current carries warm water and the Gulf Stream carries cold water.

Therefore, option B is the correct answer as it accurately describes the difference between the Brazil Current and the Gulf Stream.
