Answer:
1.64 L
Explanation:
P₁V₁ = P₂V₂
P₁ = 2.25 atm
V₁ = 0.75 L
P₂ = 1.03 atm
V₂ = ?
(2.25 atm)(0.75 L) = (1.03 atm)V₂
[(2.25 atm)(0.75 L)]/(1.03 atm) = V₂
V₂ = 1.64 L
Answer:
Na+
Explanation:
The equation would be:
HCl (aq) + NaOH (aq) --> HOH (l) + NaCl (aq)
The equation is already balanced and the NaCl will disassociate in Na+ and Cl- and HCl will disassociate into H+ and Cl- and NaOH will disassociate into Na+ and OH-. Na+ is on both sides of the equation and stays the same, so Na+ will be the spectator ion.

<h2>Answer:</h2>
The three examples of convection are
- The stack effect
- Oceanic circulation
- Hot air balloon
<h2>Explanation:</h2>
The stack effect is also referred to as the chimney effect which is the movement of air inside and outside of buildings, flues or any other objects because of buoyancy principle. In oceanic circulation warm water around the equator circulates towards the poles and the cooler water at the poles moves towards the equator. In hot air balloon, a heater inside the balloon heats the air and so the air moves upward.
