Write the balanced COMPLETE ionic equation for the reaction when
Vera_Pavlovna [14]

Answer:

Ba²⁺(aq) + 2 NO₃⁻(aq) + 2 Rb⁺(aq) + 2 OH⁻(aq) = Ba(OH)₂(s) + 2 Rb⁺(aq) + 2NO₃⁻(aq)

Explanation:

Let's consider the molecular equation between barium nitrate and rubidium hydroxide to produce barium hydroxide and rubidium nitrate.

Ba(NO₃)₂(aq) + 2 RbOH(aq) = Ba(OH)₂(s) + 2 RbNO₃(aq)

The complete ionic equation includes all the ions and the molecular species.

Ba²⁺(aq) + 2 NO₃⁻(aq) + 2 Rb⁺(aq) + 2 OH⁻(aq) = Ba(OH)₂(s) + 2 Rb⁺(aq) + 2NO₃⁻(aq)

Why do we experience the changing of the seasons on earth
iren2701 [21]

<u>Answer:</u>

Earth's axis and position around the sun.

<u>Explanation:</u>

Earth's tilted axis causes the seasons to change. Throughout the year, different parts of Earth acquire the Sun's most direct rays(Or heat) because of the orbital rotation of Earth. So, when the North Pole tilts toward the Sun, it's summer inside the Northern Hemisphere. And whilst the South Pole tilts towards the Sun, it is winter within the Northern Hemisphere and vise versa.

Write a rap about fossils please
givi [52]

Answer:

CHORUS 1:

Fossil rocks are in the ground tonight

They’ve been down there for a really long time

They contain the history of life

They’ve been down there for a really long time

Fossil rocks are in the ground tonight

They’ve been down there for a really long time (They’re the schist*)

They are literally on the grind

Take your hammer out and... break that

VERSE 1:

Look at the ground. Partly rock

Plus plants and animals stuck in their spot. Huh

Each new layer stackin’ up

So the oldest on the bottom and the newest on top

“So how old is your fossil, bro?”

Well it was pretty far down so it’s pretty darn old

And I dated this one, so I gots to know

It’s from 3.5 billion years ago

Yo. I got that lava flow, Volcano

Air full of particles & smoke

There goes life as they know

Now that’s a blast! But most rocks ain’t movin’ that fast

The sediment’s evidence. Like a present tellin’ us of the past

CHORUS 2:

Take your chisel out and… flake that

BREAK:

Everyday I’m Shovelin’…

Brushin’ ‘em, Brushin’ ‘em

VERSE 2:

Brush it off and hear the story of life as told through rock

The story of the earth as told through life. Now stop... do the trilobite

Continental plates (are driftin’)

Mountains in the states (upliftin’)

Tend to isolate (species)

By affecting who you mate with (believe me)

Slow moves. Long time. Push up mountains to the sky

Slow moves. Long time. Open up a great divide

Slow moves. Long time. Fossils found on either side

Fossils found they tell us why... tell the history of life....

Slow moves. Long time. Slow moves. Long time

Slow moves. Long time. Slow moves. Long time

Plates are driftin’ at ya boy. Plates are driftin’ at ya boy

Plates are driftin’ at ya boy. Now boom. There’s an asteroid
