Answer: SnO2 + 2 H2 = Sn + 2 H2O
Explanation: I used a balance equation website. It's called WebQC if you want to check it out for future help.
Notice the subscript went from 83 to 84 and the 214 stayed the same that means it was beta decay.
True
It’s true because models are based on real world problems to help grasp a understanding of the problem
The statement that describes what makes a base weak is that the base will be unable to dissociate completely in water.
<h3>What is a base?</h3>
A base is any of a class of generally water-soluble compounds, having bitter taste, that turn red litmus blue, and react with acids to form salts.
Bases usually dissociate into hydroxide ions (OH-) when in an aqueous solution.
However, a base is termed weak or strong depending on it's ability to dissociate completely. A weak base does not dissociate completely into hydroxide ions when in an aqueous solution.

It allows a scientist to understand the history of metamorphic rock by estimating the temperature, depth, and pressure at which a rock undergoes metamorphism.
Hope that helped!
