Mr. Rutherford's chemistry class was collecting data in a neutralization study. Each group had 24 test tubes to check each day f

or one week. Students had to check to see whether the solution in each test tube was acidic, basic, or neutral. What would be the MOST efficient method for collecting this data and recording it for later analysis? A) pH paper and a notebook B) pH probe linked to a graphing calculator C) photometer linked to a graphing calculator D) phenolphthalein solution and a computer spreadsheet

How many moles of CuO are needed to react with 5.9 moles of CO2
Likurg_2 [28]

Answer:

If 5.9 moles of CO₂ react, 5.9 moles of CuO will also react.

Explanation:

The balanced reaction is:

CuO + CO₂ → CuCO₃

By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:

  • CuO: 1 mole
  • CO₂: 1 mole
  • CuCO₃: 1 mole

You can see that the stoichiometric relationship between CuO and CO₂ is 1: 1. In other words, for each mole of CuO that reacts, one mole of CO₂ will also react.

So <u><em>if 5.9 moles of CO₂ react, 5.9 moles of CuO will also react.</em></u>

2.0 grams of ZnSO4 reacts completely with Li2CO3; how many grams of Li2SO4 would be produced?
grin007 [14]
Moles of ZnSO4 = Mass/Mr
= 2/(65.4 + 32.1 + (16 x 4))
= 0.012383.... mol

Since there is no chemical equation provided, I will assume that the ratio of ZnSO4:Li2CO3 is 1:1

Therefore there are 0.012383 mil of Li2SO4 as well
So the mass would be Moles x Mr = 0.012383.... x ((6.9 x 2) +32.1 + (4x16))
= 1.360 g of Li2SO4 produced
