Answer:
First, both ingredients are excellent at dissolving tough grime. However, vinegar alone will simply run off of most surfaces, while dish soap is too thick to use as a spray. But when you mix them together, you get an effective, sprayable cleaner that sticks to any surface!
Answer:the medication would not last as long
Explanation:
Because of the desolving of the tablet so quickly it would
Answer:
Explanation:
To convert from moles to mass, the molar mass must be used.
First, write the chemical formula for carbon monoxide. Since the carbon (C) comes first without a prefix, there is 1 carbon atom. The prefix mono- before oxide means 1, so there is also 1 oxygen (O) atom. The formula is CO.
Next, look up their molar masses on the Periodic Table.
- C: 12.011 g/mol
- O: 15.999 g/mol
Since there is 1 atom of each, the molar masses can be added.
- CO: 12.011 g/mol + 15.999 g/mol = 28.01 g/mol
Use this molar mass as a ratio.
Multiply by the given number of moles:5.55
The moles of carbon monoxide cancel.
Multiply.
The original measurement of moles has 3 significant figures, so our answer must have the same. For the number we calculated, it is the ones place. The 4 in the tenths place tells us to leave the 5.
5.55 moles of carbon monoxide is about 155 grams.
Each mole of nitrogen produces 2 moles of ammonia.
One mole of gas occues 22.4 liters under STP.
Moles of ammonia = 100/22.4
= 4.46 moles
Moles of nitrogen required = 4.64/2
= 2.32 moles
Mass = moles x Mr
Mass of nitrogen = 2.32 x 28
= 64.96 grams
I would say the answer is C.
C. transition, as they show variable oxidation states.
