Tell me why in Louisiana it always gotta freaking have a hurricane
Gala2k [10]
Why do so many storms target the state? The easterly winds typically blowing across Jacksonville in the summer flow out of the Azores/Bermuda high-pressure system which also steers many hurricanes into the Gulf. In June and October, storms are more likely to move up the Gulf from the south and southwest.

100 ml is drawn from 0.1 M solution of KCl and added to 900 ml of water. What is the
grandymaker [24]

Answer:

The new concentration will be 0.01 M.

Explanation:

To determine the new concentration we use the following formula.

concentration (1) × volume (1) = concentration (2) × volume (2)

concentration (1) = 0.1 M

volume (1) = 100 mL

concentration (2) = unknown

volume (2) = 100 mL + 900 mL = 1000 mL

concentration (2) = [concentration (1) × volume (1)] / volume (2)

concentration (2) = (0.1 × 100) / 1000 = 0.01 M

How many of the following postulates of Dalton's atomic theory are still scientifically accepted? I. All atoms of the same eleme
Neko [114]
<h2>The required "options are (II), (III), and (IV)".</h2>

Explanation:

Postulates of Dalton's atomic theory which are scientifically accepted are:

  • Atoms are indestructible.
  • Compounds are combinations of different atoms.
  • A chemical reaction changes the way atoms are grouped together.

Postulates of Dalton's atomic theory which are not accepted scientifically are:

  • All atoms of the same elements are identical.

            The theory states that the atoms of the same element are identical in every aspect but it is now scientifically proved that the same element should differ in their mass which is known as isotopes.
