Answer:

3. depth of 50 - 200 miles.

Explanation:

  • The foci is the focus spot down below the epicenter where the earthquake occurs in the crust and upper mantle. The presence of a subduction zone where the plate collides with one another.
  • The earthquake range from 0-800 mile of depth the deep foci earthquakes are of range 50 to 300 miles as the stress regimes are deeper downwards like a dip down.
  • This zone is also called as the dipping seismic or the wadis Benioff zone. As the san Andreas fault has a shallow depth of about 20 m depth which is considered the deepest.

Give all possible ml values for orbitals that have each of the following:<br> (a) l = 3;
Angelina_Jolie [31]

At l = 3, ml =+3,+2,+1,0,-1,-2,-3

What are quantum numbers?

  • Quantum numbers are used to describe where around a nucleus a particular electron can be found.
  • In any given atom, each electron can be described by four quantum numbers.
  • These are n,l,m1,ms
  • The values that each number can be are based on a set of rules.

What is a magnetic quantum number ?

  • It describes the orientation of the orbitals.
  • It is represented as ml.
  • The value of this quantum number ranges from (-l to +l).
  • When l = 2, the value of  will be -2, -1, 0, +1, +2.

The statement "electrons have a negative charge" is true. Select the correct evidence scientist have that proves this statement
Kryger [21]

The question is incomplete but i will try to offer as much help as i can.

Answer:

See explanation

Explanation:

The electron was discovered by J.J Thompson. His model of the atom was called the plum-pudding model of the atom.

He discovered that cathode rays being negatively charged particles were deflected by a magnet in just the same way as moving, negative electrically charged particles.

Similarly, in an electric field, they are deflected towards the positive plate of the electrostatic field which shows that they are negatively charged.

One disadvantage of burning propane (C3H8) is that carbon dioxide is one of the products. The released CO2 increases the growing
Hoochie [10]

Answer:

80 MOLES OF WATER ARE PRODUCED WHEN 20 MOLES OF PROPANE ARE BURNED IN EXCESS OXYGEN ON A GAS GRILL.

Explanation:

Equation for the reaction:

C3H8 + 5 O2 --------->  4 H2O + 3 CO2 + Heat

The above equation is in the presence of excess oxygen.

In this reaction,

1 mole of propane forms 4 moles of H2O

If 20 moles of propane were to be used, how many moles of water will be produced?

1 mole of propane = 4 moles of water

20 moles of propane = ( 4 * 20 ) moles of water

= 80 moles of water.

So, if 20 moles of propane were burned in excess oxygen, 80 moles of water will be formed. Propane is heavier than air and when properly combusted produces a large amount of heat. It is also non toxic.
