<span>A mineral phase change involves the action of a mineral changing physical form. This can involve changing from a solid to a liquid, changing in to a gas form, etc. This phenomenon may sometimes be referred to as metamorphism.</span>
Answer:
x = 11.
This checks out since 11 + 10 = 21.
Explanation:
Answer:
The new volume is 7,606.96 Liter.
Explanation:
The combined gas equation is,

where,
= initial pressure of gas in the balloon = 0.918 atm
= final pressure of gas in the balloon = 0.0012 atm
= initial volume of gas in the balloon = 
= final volume of gas in the balloon = ?
= initial temperature of gas in the balloon = 
= final temperature of gas in the balloon = 
Now put all the given values in the above equation, we get:



The new volume is 7,606.96 Liter.
FALSE there are many ways to conduct scientific investigations
Answer:
The correct answer is C)H2PO4-(aq) + H2O(l)--> H3O+(aq) + HPO42-(aq)
Explanation:
The acid dissociation equilibrium involves the loss of a proton of the acid to give the conjugated acid. In this case, the acid is H₂PO₄⁻ and it losses a proton (H⁺) to give the conjugated acid HPO₄²⁻ (without a proton and with 1 more negative charge). In the aqueous equilibrium, the proton is taken by H₂O molecule to give the hydronium ion H₃O⁺.
H₂PO₄⁻(aq) + H₂O(l)--> H₃O⁺(aq) + HPO₄²⁻(aq)
