Answer:

<u>D. Wheat</u>

Explanation:

  • As prairies grassland cover about 40% of the United States they are recently developed systems of North America. These grasslands stretch from the rocky mountain to east of Mississippi River and south of texas.
  • The grassland is a  biome, including, purple needlegrass, wild oats, foxtail, ryegrass, and buffalo grass. Thus prairies are also known as the wheat bowl of North America and Texas is known as the <u>wheat belt.</u>  
  • As being a winter crop it gets most of its required nutrients from the fertile soil and nearly 50% of the production is exported from the state.

An isotope of carbon has 8 neutrons. What is the correct hyphenated symbol for this isotope?
Rom4ik [11]

Answer:

Carbon-14 or C-14

Explanation:

Since the isotope is a carbon isotope, it means the the atomic number of the isotope is 6.

The atomic number of an element is the proton number.

Therefore, the isotope has a proton number of 6

Now we need to obtain the mass number of isotope in order to write the symbol of the isotope. This is illustrated below:

Mass number = Proton +Neutron

Proton = 6

Neutron = 8

Mass number = 6 + 8

Mass number = 14

Therefore, the symbol of the isotope is carbon-14 or C-14

1. For HF and HBr, the partial positive charge on H atom is 0.29 and 0.09, respectively. Use electronegativities (EN) to explain
Assoli18 [71]

Answer:

Electro negativity decreases down the group

Explanation:

One of the known periodic trends is that electro negativity decreases down the group but increases across the period. The electro negativity of fluorine is 3.98 on the Pauling's scale while that of bromine is 2.96. Hence the magnitude of charge separation and degree of partial positive charge on hydrogen in HF must be much greater than that of HBr to a large extent due to the significant difference in electronegativity in HF compared to HBr.
