Methane reacts with chlorine in the presence of ultraviolet light
earnstyle [38]

Answer:

When a mixture of methane and chlorine is exposed to ultraviolet light - typically sunlight - a substitution reaction occurs and the organic product is chloromethane. CH 4 + Cl 2 → CH 3 Cl + HCl However, the reaction doesn't stop there, and all the hydrogens in the methane can in turn be replaced by chlorine atoms.

A piper delivers 9.98 g of water at 19 degrees Celsius. What does the pipet deliver
leva [86]

Answer:

the volume = 9.99 ml

Explanation:

in your Q we need to calculate the volume does the pipet deliver so , we are going to use this formula:

the volume = mass / density

here we need to know the density of water at a certain temperature 19 degrees Celsius ,so I used an external source   to get the density of water at 19 degrees Celsius because it is changing with different temperatures

where mass here = 9.98 g

and  the density of water at  temperature 19 degrees Celsius=  0.998405mL

-1

by substitution :

the volume = 9.98 g / 0.998405mL

-1

                   ≅ 9.996 ml = 10 ml

Barium reacts with a polyatomic ion to form a compound with the formula Ba(X). What would be the formula for a salt formed betwe
Luba_88 [7]

Answer:

Na_2(X)

Explanation:

Common ionic charge exhibited by Barium is +2.

Compound formed by Barium and polyatomic ion (X) is Ba(X).

Therefore, ionic charge on polyatomic (X) should be -2 in order to Ba(X) to be neutral.

Common ionic charge exhibited by sodium is +1.

If sodium forms salts with (X), Then, two atoms of sodium will be needed in order to make it neutral. in compounds or salts, no. of atoms are represented as subscripts. Therefore, formula of salts betweem sodium and polyatomic ion should be Na_2X
