Im not sure if I got this one correct? Which pair of compounds that will make a buffer solution when combined. Place an ✖️ in front.
✖️H2CO3 & CO3
NH4+ & NH3
H2CO3 & C2H4O

Q2. Write the chemical formula of the conjugate base of each of the following compounds:
a.
CHO,
I
b.
H. PO ,

that's what i got you can count the number of atoms

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
