Answer:Because the amount of water vapor in the air increases

Explanation:In humid climates, thunderstorms often cause heavier rain than general wintertime rainfall since moisture content in the air typically is higher in the spring and summer, and since air usually rises at a much more rapid rate within developing thunderstorms than in general winter systems.During very heavy rainfall, where all of the water in the atmosphere is often rained out, the water vapour content governs the amount of rainfall. The higher the humidity the greater the water vapour, and the more rain we're likely to see. HOPE THIS HELPS ^w^

How many grams of zinc metal will react completely with 5.4 liters of 2.8 M HCl? Show all of the work needed to solve this probl

Assoli18 [71]

The reaction is
Zn (s) + 2 HCl (aq) ----> ZnCl2 (aq) + H2 (g)
which is already balanced
5.4 L of 2.8 M HCl contains
5.4 L (2.8 M) = 15.12 moles HCl
The amount of Zinc that will react completely with the acid is
15.12 mol HCl (1 mol Zn / 2 mol HCl) (65 g Zn/1 mol Zn) = 491.4 g Zn

A chemist must prepare 800.0mL of sodium hydroxide solution with a pH of 12.10 at 25°C. She will do this in three steps: Fill a

AnnZ [28]

Answer:

0.42 g

Explanation:

We have:

pH = 12.10 (25 °C)

V = 800.0 mL = 0.800 L

To find the mass of sodium hydroxide (NaOH) we can use the pH:

$14 = pH + pOH$

$pOH = 14 - pH = 14 - 12.10 = 1.90$

$pOH = -log ([OH^{-}])$

$[OH]^{-} = 10^{-pOH} = 10^{-1.90} = 0.013 M$

Now, we can find the number of moles (η) of OH:

$\eta = ([OH]^{-})*V = 0.013 mol/L * 0.800 L = 1.04 \cdot 10^{-2} moles$

Since we have 1 mol of OH in 1 mol of NaOH, the number of moles of NaOH is equal to 1.04x10⁻² moles.

Finally, with the number of moles we can find the mass of NaOH:

$m = \eta * M$

Where M is the molar mass of NaOH = 39.9 g/mol

$m = 1.04 \cdot 10^{-2} moles * 39.9 g/mol = 0.42 g$

Therefore, the mass of sodium hydroxide that the chemist must weigh out in the second step is 0.42 g.

I hope it helps you!

Scientists believe the Earth’s core is around 6,000 degrees Celsius. Where does this heat come from?

Nataliya [291]

The heat in the core of the Earth has several sources including:
1- The heat produced from the decaying of radioactive elements
2- The heat that was originally produced during the formation and accretion of the planet itself (This heat has not yet faded)
3- The heat produced during friction when denser material and elements sink into the planet's center.

What characteristics of the Baobab tree allow it to live in a dry enviroment?

sergejj [24]

It produces leaves during the wet season and when they grow they're in tiny clusters which helps the limiting of water loss during the dry season.
