Balanced chemical reaction:
2HNO₃<span>(aq) + Sr(OH)</span>₂(aq) → 2H₂O(l) + Sr(NO₃)₂<span>(aq).
Balanced ionic reaction:
2H</span>⁺(aq) + 2NO₃⁻(aq) + Sr²⁺(aq) + 2OH⁻(aq) → 2H₂O(l) + Sr²⁺(aq) + 2NO₃⁻(aq).
Net ionic reaction:
2H⁺(aq) + 2OH⁻(aq) → 2H₂O(l).
(aq) means that substances are dissociated on cations and anions in water.
Answer:
Matter cannot be created destroyed
Explanation
Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.
0.01068g
Explanation:
Given parameters :
Number of atoms = 5.34 x 10²⁰ atoms
Molar mass of carbon = 12g
Unknown:
Mass of carbon = ?
Solution:
A mole of a substance is unit that contains the Avogadro's number of particles.
1 mole = 6.02 x 10²³ atoms ;
In 5.34 x 10²⁰ ;
Number of moles =
= 8.9 x 10⁻⁴moles
Mass = number of moles x molar mass = 8.9 x 10⁻⁴ x 12 = 0.01068g

Answer:
SN1 = a stepwise loss of a leaving group to form a carbocation followed by nucleophilic attack
Explanation:
Since 2-methyl-2-butanol is tertiary alcohol, the first step will be loss of leaving group to form a 3° carbocation which is very stable and favours SN1, followed by attack of nucleophile
