How can a montain range cause a large dessert?
Simora [160]

Explanation:

An extensive mountain range can cause a large desert area.

Mountains are usually geologic features that have heights that are greater than 600m.

  • Due to towering heights of mountains, they have serious effect on the weather and climatic pattern in an area.
  • Air masses that are warm are usually moisture laden.
  • As they try to cross the steep slopy side of one mountain, their pressure reduces and they drop the vapor in them causing rainfall.
  • The cold wind moves to the other side.
  • This side is called the leeward side.
  • Cold air is dry and lacks moisture.
  • This can lead to the formation of a desert.

When hcl(aq) and naoh(aq) are mixed in a beaker, the beaker feels warm to the touch. what is known about the enthalpy of this re
Nady [450]

The balanced chemical equation representing the neutralization reaction of hydrochloric acid (HCl) and sodium hydroxide (NaOH),

HCl (aq) + NaOH(aq) ---> NaCl(aq) + H_{2}O(l) + Heat

This reaction is exothermic that is it proceeds by the release of heat energy. This heat energy is lost to the surroundings. This is the reason for the warming up of the beaker where the reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH) takes place. The enthalpy of such reaction will be negative as the reaction is exothermic.

How can u detect the which d-orbital is used in making bond ??
zavuch27 [327]
This is much more simple than it sounds... 

s has 1 orbital; p = 3 orbitals; d= 5 orbitals; f= 7 orbitals. (you just need to memorize this) 
A maximum of 2 electrons can occupy each orbital. 

<span>The number of orbitals that each atom has is based on the number of electrons it has and by consequence it's position on the periodic table. </span>

The orbitals occur in sequence. Whereby electrons fill first from the lowest energy level (1s) outwards to the highest. 
3p = the following sequence. 
1s, 2s, 2p, 3s, 3p: these 'sets' can hold the following electrons respectively (2+2+6+2+6) 18 which corresponds with argon on the periodic table. REMEMBER p has 3 orbitals, d has 5 orbitals. So, here there are 9 orbitals. 

The sequence through n=4 is: 

<span>1s, 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, 4f 
</span>

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Can someone tell me a summary of volcanoes and plate tectonics? (Please quickly!)
slamgirl [31]
TECTONIC PLATES

a theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates which move slowly over the underlying mantle.
VALCONES AND TECTONIC

Most volcanoes form at the boundaries of Earth's tectonic plates. These plates are huge slabs of the Earth's crust and upper mantle, which fit together like pieces of a puzzle. These plates are not fixed, but are constantly moving at a very slow rate. They move only a few centimeters per year.
