It has been proposed that North America is moving west at about 2 cm per year. How many kilometers would it move in 5,000 years? (Note: 2 cm is a measurement so your final answer should have significant figure rules applied.)

Answers

Answer: 0.1 km

Explanation:

1) Multiply the rate (speed) by the time: 2 cm / year × 5,000 year = 10,000 cm

2) Convert cm to km, using these well know conversion factors:

1 km = 1,000 m

1 m = 100 cm

⇒ 10,000 cm × [1 m / 100 cm] × [1 km / 1,000 m] = 0.1 km
Well it would move 10,000cm so converting that into km would be it would move 0.1km 

Which expression could represent theconcentration of a solution?
(1) 3.5 g
(2) 3.5 M
(3) 3.5 mL
(4) 3.5 mol

Answers

There are a couple of ways in which you can express the concentration of a solution, and here they are: gram per liter (g/L), molarity (M), parts per million (ppm.), and percents (%). 
As you can see, only M appears in your answers, which means that the correct option should be (2) 3.5 M.

The expression for representation of concentration of a solution has been 3.5 M. Thus, option 2 is correct.

Concentration has been defined as the amount of substance present in a volume of solution. The concentration has been given by varying units. The concentration has been given by mass per unit volume.

It can be represented by moles/L or g/L. The expression that has been similar to moles/L has been molarity.

Thus, the expression for representation of concentration of a solution has been 3.5 M. Thus, option 2 is correct.

What is the chemical formula of a trisaccharide made of three bonded glucose molecules?

Answers

 (6 C, 12 H, 6 O) x 3 - (H20) x 2 = 18 carbons, 32 hydrogens, 16 oxygens 

the answer is C18H32O16 
because you use 2 water molecules to form molecule...so you are losing 4 H molecules and 2 O molecules). the first 2 glucose molecule combine losing one water molecule; and the third combines to them, losing another water molecule.

Calculate the number of moles in a 14.5 gram sample of C4H10.

Answers

Moles= mass divided by molar mass
Molar mass= 12.01(4) + 1.01(10)
                 = 58.14g/mol

Moles=14.5g / 58.14g/mol
         =0.249

Therefore there are approx 0.249 moles in a 14.5g sample of C4H10

Molecules in food contain chemical energy that cells use to produce ____________________. (1 point

Answers

Molecules in food contain chemical energy that cells use to produce ATP = adenosine triphosphate. 

Answer:

Molecules in food contain chemical energy that cells use to produce Adenosine triphosphate ATP. Respiration is that the method by that cell get energy within the sort of ATP. Adenosine triphosphate captures energy obtained from the breakdown of food molecules and releases it to fuel alternative cellular processes. ATP, is that the primary carrier of energy in cells. Once energy is required by the cell, it's born-again from storage molecules into ATP.
