Answer:

The wind is starting to blow stronger, and when you’re riding in a basket under a hot air

balloon, just 400 feet above ground, that’s not necessarily a good thing. Keith Rodriguez looks

to the horizon and squints. He had planned to take off from Scioto Downs, a horse racetrack

south of Columbus, Ohio, fly a few miles north, and land his balloon in a barren cornfield next

to his pickup truck.  

Then the wind changed. Instead of a light breeze from the south, now Rodriguez’s bright red

balloon is getting hit by stronger, colder winds from the west. He has plenty of propane fuel in

his tank—he probably could ride the wind halfway to Pennsylvania. But that would be

dangerous. Rodriguez’s choice of landing sites just became very limited. As the balloon

switches direction and floats east, everything below becomes a wide carpet of suburban

sprawl—big‐box stores, major highways, strip malls. Beyond the stores lie forests.

Why don't metals form covalent compounds?
Firdavs [7]
Metals don't form covalent bonds because of the low ionization energes of the metal atoms. It is easier for them to release electrons rather than sharing it. But this is not always the case, there are some metals that can form covalent bonds.

Calculate the mass percentage of Na2SO4 in a solution containing 10.9 g Na2SO4 in 482 g water.
boyakko [2]

Answer:

The answer to your question is 2.21 %

Explanation:

Data

mass of Na₂SO₄ = 10.9 g

mass of H₂O       = 482 g

Formula

Percent by mass = \frac{mass of solute}{total mass} x 100

Substitution

Percent by mass = \frac{10.9}{10.9 + 482} x 100

Simplification and result

Percent by mass = \frac{10.9}{492.9} x 100

       Percent by mass = 0.022 x 100

       Percent by mass = 2.21

PLEASEEE HELPPP I SUCK AT CHEM :(
Luda [366]

Answer:

a) H2SO4 + 2KOH -> 2H2O + K2SO4

b) 9.809 ml

Explanation:

Number of Moles = Mass/ Molar Mass

Therefore: Mass = Number of moles * Molar Mass

--------------------------------------------

Molar mass of H2SO4:

H2= 2.02

S= 32.07

O4= 64

--------------------------------------------

H2SO4 has the molar mass of 98.09

--------------------------------------------

the Moles of H2SO4 is given to be 0.100M

Therefore:

Mass= 98.09*0.1

          = 9.809g

---------------------------------------------------

Assuming that 1 g= 1 ml, the volume of sulfuric acid is 9.809 ml.
