Two mechanical shafts are joined together at their ends. Together their total is 18 and 2/9 ft. if one shaft is 13 and 4/7 ft long , how long must the other shaft be?

**Chemistry**

You were right the answer was -20600.

**Chemistry**

q=mass*Specific heat of liquid*change in temp q=42*4.18*35=6144.6 q=mass* specific heat of ice*change in temp q=42*2.03*5=426.3 q=heat of fusion of ice*moles q=6010*2.3=14023 Then add all three together and get 20593.9 Joules

**Chemistry**

Calculate the heat released when 42.0 g of water at 35.0 degrees Celsius is converted to ice at -5.0 degrees Celsius. The specific heat of ice is 2.03 J/(g C), the molar heat of fusion of ice is 6010 J/mol, and the specific heat of water is 4.18 J/(g C) (Hint: Be sure to ...

Under certain conditions, nitrogen gas reacts with oxygen gas to form nitrogen monoxide gas. How many total electrons are transferred for each molecule of nitrogen or oxygen?

**Chemistry**

Thank You!!

**Chemistry**

Is this answer correct? I looked up in the computer and it said the answer is supposed to be 270.84g of CO2 but I thought I did this problem right.

**Chemistry**

If 116g of butane burns in presence of 320g of oxygen, how much carbon dioxide will be produced? What is limiting reagent? So This is how I worked it out: 116gC4H10*1/58.12(molar mass of C4H10)*8 moles CO2/2 moles C4H10*44/1(molar mass of CO2)=351.27g of CO2

**Chemistry**

Mothballs are composed of a chemical called naphthalene which has a formula of C10H8 a) what is the mass of a single naphthalene molecule in amu? b) what is the molar mass of naphthalene? c) what is the mass of a single naphthalene molecule in grams? I think I got b: 128.16 g/...

**Chemistry**

Well, If Fe atomic mass is 55.85 and O is 16, then multipy 55.85 by two and 16 by 3 and get 159.7 g/mol. Then divide 17g by 159.7 g/mol and get .106 moles.

**Chemistry**

How many moles of compound are present in 17g of Fe2O3? I think I know how to do this, so if someone can show me so I can check my work against it. My answer was .106 moles of Fe2O3.

**Chemistry**

It wasn't a typo. It is (PO3)2 So you are saying it should be a) 11 moles of atoms b) 1 mole of PO3^3- ions c) 2 ions of PO3^3- ions (because of the subscript 2 that follows (PO3)2)

**Chemistry**

a) how many moles of atoms are in 1 mole of Ca3(PO3)2 b)If I have 1 mole of Ca3(PO3)2, how many moles of PO3^3- ions do I have? c)How many individual PO3^3- ions do I have?
