Column1, 1000
How many more neutrons are found in the nucleus of an iron atom with a mass number 55 than in the nucleus of a calcium atom with a mass number 39?
Column 2, 200
An element in column 16 (6A) on the periodic table contains how many valence electrons?
Column 2, 600
Copper forms an ion with a +2 charge. This ion forms when a neutral copper atom does what?
Column 3, 200
Use the following balanced chemical equation to answer the following:
B2Br6 + 6HNO3 → 2B(NO3)3 + 6HBr
How many moles of HBr will be produced with 11 moles of HNO3?
Column 3, 400
Use the following balanced chemical equation to answer the following:
4NH3 + 5O2 → 4NO + 6H2O
How many moles of H2O will be produced with 15 moles of O2?
Column 3, 600
Consider the balanced chemical reaction:
2Fe + 3 H2S04 → Fe2(SO4)3 + 3H2
How many moles of Fe2(SO4)3 will be produced if we begin with 150 grams of iron?
Column 3, 800
Use the following balanced chemical equation to answer the following:
B2Br6 + 6HNO3 → 2B(NO3)3 + 6HBr
How many grams of B(NO3)3 will be produced with 21 moles of HNO3?
Column 3, 1000
Use the following balanced chemical equation to answer the following:
4NH3 + 5O2 → 4NO + 6H2O
How many grams of NH3 are needed to produce 90 grams of water?
Column 4, 1000
In the formula: (NH4)2SO3
The sulfite ion has a charge of (2-), therefore the ammonium
ion has a charge of this.
