How will the temperature of the surface change?
kogti [31]

Answer:

o Surface Type- Because the atmosphere is heated by the Earth's surface, the surface type plays an important role in the surface air temperature. o Elevation and Aspect- Higher altitude generally has colder temps b/c the air is less dense and there are fewer molecules to absorb incoming solar radiation.

The Earth's surface is actually what heats the air above it.  

Explanation:

The energy from the sun is "short-wave", and as such air is transparent to it. The sunlight goes right through the air without heating it at all. This "short-wave" radiation is absorbed by the Earth which then heats up. The heated Earth then emits it's own radiation but it is in the infrared part of the spectrum or "long-wave" radiation. This heat is what warms the atmosphere.

Predict the products of hydrobromic acid, H B r , reacting with magnesium hydroxide, M g ( O H ) 2 . Select one or more:
Aliun [14]

Answer:

Magnesium bromide, MgBr2, and water, H2O.

Explanation:

Hello!

In this case, since HBr is an acid and Mg(OH)2 is a base, an acid-base reaction is undergone, by which a salt and water are produced as neutralization products:

HBr+Mg(OH)_2\rightarrow MgBr_2+H_2O

However, it need to be balanced since two bromine atoms are produced, therefore we write:

2HBr+Mg(OH)_2\rightarrow MgBr_2+2H_2O

Thus, the products are magnesium bromide, MgBr2, and water, H2O.

Best regards!

Answer:

The heat of reaction is the energy that is released or absorbed when chemicals are transformed in a chemical reaction. It describes the change of the energy content when reactants are converted into products.

Explanation:

Yeah, that would confuse me a bit but then you read it and then you will get that answer above! Have a great rest of your day!
