grigory [225]

Answer:

Explanation:

_Andesitic__ magma is a mix between basaltic and rhyolitic magma. The eruption that would most likely result from this magma is a _strombolian____ eruption.

Andesitic magma straddles between basaltic and rhyolitic magma. They produce rocks that shows both basaltic and rhyolitic affinity. Examples of rocks that results from this type of magma is andesite.

Strombolian eruptions results from this type of magma. They are charactised by moderate to low bursts of magma. Their explosivity is between 2 and 3.

Determine the mass of each sample 1.55 kmol sulfur trioxide
xxMikexx [17]

Explanation:

Given parameters:

Number of moles of the sulfur trioxide = 1.55kmol = 1.55 x 10³mole

Unknown:

Mass of the sulfur trioxide = ?

Solution:

To solve for the mass of the sample of sulfur trioxide:

  •  Find the molar mass of the compound i.e SO₃

          atomic mass of S = 32g

                                    O = 16g

              molar mass = 32 + 3(16) = 80g/mol

  • Use the formula below:

           mass of SO₃ = number of moles x molar mass

           mass of SO₃ =  1.55 x 10³ x 80 = 124000g or 124kg

The white tern is a seabird that catches fish by plunging into the water. What physical features of the bird likely make this fe
V125BC [204]

White tern catches fish including crustaceans, flying fish, squid, and others. Prior of plunging into water, it hovers initially over the water surface and then either dives or dips in the surface, without getting entirely submerged into water, and catches its target.  

The food or fish is captivated in its small, however, sharp black beak that is specific as it bent upwards and tapers to a sharp point. It also possesses a long slender body with tapering, long wings, all of which encourage its diving or dipping activity into the surface of the water.
