If 20 grams of sulfur reacts with 30 grams of oxygen, predict the mass of sulfur trioxide produced. Why would you expect this
Scilla [17]
20/32=0.625 moles of sulfur
30/16 = 1.875 moles of oxygen
The formula requires 1 mole of sulfur for 3 moles of oxygen which means that their is no limiting reactant as that is the ratio found thus it will react to completion forming 50 grams of product or sulfur trioxide

How are waves reflected, absorbed, and transmitted through various materials<br>​
EastWind [94]

Answer:

Electromagnetic Radiation

Explanation:

When light shines on an object, it is reflected, absorbed, or transmitted through the object, depending on the object's material and the frequency (color) of the light. However, because light can travel through space, it cannot be a matter wave, like sound or water waves.

Describe the silica tetrahedron
Travka [436]

Answer:

This fundamental structural unit consists of a silicon cation surrounded by four oxygen anions giving it four negative charges. It is found in all silicate minerals (ie. amphibole, olivine, pyroxene, quartz, feldspar, etc.). The silica tetrahedra may be arranged in chains (ex: pyroxenes), double chains (ex. amphiboles), sheets (ex: micas), and frameworks (ex: quartz, feldspars), forming the basic structure of the planet.

2. HOW MUCH HEAT IS REQUIRED TO BE RELEASED WHEN
jarptica [38.1K]

Answer: -112200J

Explanation:

The amount of heat (Q) released from an heated substance depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)

Thus, Q = MCΦ

Since,

Q = ?

Mass of water vapour = 30.0g

C = 187 J/ G°C

Φ = (Final temperature - Initial temperature)

= 100°C - 120°C = -20°C

Then apply the formula, Q = MCΦ

Q = 30.0g x 187 J/ G°C x -20°C

Q = -112200J (The negative sign does indicates that heat was released to the surroundings)

Thus, -112200 joules of heat is released when cooling the superheated vapour.
