2Mg+ O₂= 2MgO
The charge of Mg is+2 and the charge of Oxygen is -2. 2 oxygen atoms will have a charge of -4 so the Mg atoms have to equal +4. A coefficient of 2 for the Mg atoms will balance it out

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

What does a chemist do​
Mama L [17]
A chemist (from Greek chēm (ía) alchemy; replacing chemist from Medieval Latin alchimista[1]) is a scientist trained in the study of chemistry. Chemists study the composition of matter and its properties. Chemists carefully describe the properties they study in terms of quantities, with detail on the level of molecules and their component atoms. Chemists carefully measure substance proportions, reaction rates, and other chemical properties. The word 'chemist' is also used to address Pharmacists in Commonwealth English.

22.5 g of silver nitrate reacts with excess magnesium bromide, determine the mass
Setler [38]

Answer:

9.82 g of Mg(NO₃)₂

Explanation:

Let's determine the reaction:

2AgNO₃  +  MgBr₂  → Mg(NO₃)₂  +  2AgBr

2 moles of nitrate silver reacts with MgBr₂ in order to produce 1 mol of magnesium nitrate and silver bromide.

We determine the moles of AgNO₃

22.5 g . 1mol / 169.87g = 0.132 moles

Ratio is 2:1.

2 moles of silver nitrate can produce 1 mol of magnesium nitrate

Then, our 0.132 moles may produce (0.132 . 1)/ 2 = 0.0662 moles

We convert moles to mass:

0.0662 mol . 148.3 g/ mol = 9.82 g
