Oxygen gas can be produced by decomposing potassium chlorate (kclo3) using the reaction below. if 125g of kclo3 is heated, what mass of oxygen gas is produced?

2kclo3(s) --> 2kcl(s) + 3 o2 (g)

The climate of the continental united states is generally 1. tropical 2. temperate 3. arctic 4. highland

Abeaker with 2.00×102 ml of an acetic acid buffer with a ph of 5.000 is sitting on a benchtop. the total molarity of acid and conjugate base in this buffer is 0.100 m. a student adds 4.70 ml of a 0.360 m hcl solution to the beaker. how much will the ph change? the pka of acetic acid is 4.740.

How many oxygen atoms are there in 3.15 moles of hcl manganese (iv) oxide, mno2
