What is the molar mass of sand (SiO2) to the hundredths place in g/mol?
ad-work [718]

Answer:

60.08g/mol

Explanation:

Given parameters:

   Formula of sand  = SiO₂

Find the molar mass of the compound to the hundredths place;

 Molar mass of Si = 28.085g/mol

  Molar mass of O  = 15.999

Molar mass = 28.085 + 2(15.999)  = 60.08g/mol

Troyanec [42]
Charles law gives the relationship between temperature and volume of gases. It  states that the volume of gas is directly proportional to temperature at constant pressure. 
V / T = k 
where V - volume and T - temperature in Kelvin and k - constant 
\frac{V1}{T1} =  \frac{V2}{T2}
where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation 
T1 - 20 °C + 273 = 293 K
substituting these values in the equation 
\frac{40.0 mL}{293 K}  =  \frac{80.0 mL}{T}
T = 586 K
temperature in celsius = 586 K - 273 = 313 °C
new temperature is 313 °C

Question Options:

A) Bituminous, peat, lignite, anthracite.

B) Anthracite, bituminous, lignite, peat.

C) Peat, anthracite, lignite, bituminous.

D) Peat, lignite, bituminous, anthracite.

E) Bituminous, peat, anthracite, lignite.

Answer: Anthracite, bituminous, lignite, peat.

Explanation:

Anthracite is a form of carbonized ancient plants; the hardest and cleanest-burning of all the coals.

Bituminous is a form of coal that is characterized by mineral pitch; a black, tarry substance, burning with a bright flame.

Lignite is a low grade brownish coal.

Peat is a form of coal formed of dead but not fully decayed plants found in bog areas, often burned as fuel.

From the definitions given above, one can categorically say the most heated is in a descending order. And According to the Question, most heated is most valuable.

How is thermal energy apart of weather changing
kirza4 [7]

Answer:

Heat, in the form of thermal energy, naturally moves from warmer substances to colder ones. When the ocean is warmer than the atmosphere, it transfers heat — through conduction and radiation — to make the air warmer. ... This redistributes thermal energy and causes changes in the weather.
