Answer
Climate, because this describes what the weather is like over a long period of time.
Answer:
The balanced equation for the dissociation of KI is
KI → K⁺ + I⁻
Explanation:
KI is the potassium iodide.
K⁺ comes from the KOH, a strong base, so the cation is the conjugate weak acid and in water it does not react.
I⁻ comes from HI, a strong acid, so the anion is the conjugate weak base and in water it does not react.
K⁻ + H₂O ← KOH + H⁺
I⁻ + H₂O ← HI + OH⁻
That's why the arrow in the reaction is in the opposite direction.
Water, Sun/Heat, and Carbon Dioxicide/Air

Answer:
1.3g/L is the density of the air
Explanation:
The room is full of air, the space that the air occupy is:
500 cm x 400 cm x 250 cm = 5.00x10⁷ cm³
The density of a substance is defined as the ratio between the mass of the substance and the space that occupy. We can express the density of air in g/L:
<em>Grams air:</em>
65 kg * (1000g / 1kg) = 65000g
<em>Liters:</em>
5.00x10⁷ cm³ * (1L / 1000cm³) = 50000L
<em>Density:</em>
65000g / 50000L =
<h3>1.3g/L is the density of the air </h3>
