Answer:

The flat sheet will completely rust before the iron cube. Since they both have the same volume, the flat sheet has more surface area than the small cube. This means more particles are exposed on the flat sheet that can react in a chemical reaction.

The flat sheet will completely rust before the iron cube. Since they both have the same volume, the flat sheet has more surface area than the small cube. This means more particles are exposed on the flat sheet that can react in a chemical reaction.

[16]. A 3.0 L container holds a sample of hydrogen gas at 150 kPa. If the pressure increases to 2 atm and the temperature remain
boyakko [2]
First, let's convert atm to kPa: 
2atm x 101.33kPa = 202.66kPa

Now, to find the pressure, you would have to use Boyle's Law: (P1V1)=(P2V2)
(150kPa x 3.0L) =  (202.66kPa x V2)
V2= <span>(150kPa x 3.0L)/202.66kPa
V2=2.2L, B is your answer. This makes because volume and pressure have an inverse relationship, so since pressure increased volume should decrease.

Write an equation that shows the formation of a strontium ion from a neutral strontium atom
Pepsi [2]

Answer:

See explanation

Explanation:

Sr(s) + 2HCl(aq) -----> SrCl2(aq) + H2(g)

Ionically;

Sr(s) + 2Cl^-(aq) ----> SrCl2(aq)

If we look at the reaction above, strontium atom was dissolved in hydrochloric acid. The strontium atom is now oxidized by the acid to give Sr^2+ ion according to the equation shown above.

27. Scott travels north 5 miles and then goes west 3 miles before coming straight back south 2 miles. What is his distance? *
belka [17]

Scott traveled 10 miles in his journey.

<u>Explanation</u>:

Scott first travels 5 miles in north direction, then he turns to west and covers 3 miles distance finally he turns to south and travels 2 miles. We need to find the total distance covered by the Scott. To find the distance we should sum up all the distances he covered in three directions 5 miles north + 3 miles west + 2 miles south = 10 miles.

Therefore we can conclude that the total distance traveled by the Scott is 10 miles.

Acetaminophen (pictured) is a popular nonaspirin, "over-the-counter" pain reliever. what is the mass % (calculate to 4 significa
77julia77 [94]

Acetaminophen as a chemical formula of C8H9NO2. The molar masses are:

C8H9NO2 = 151.163 g/mol

C = 12 g/mol

H = 1 g/mol

N = 14 g/mol

O = 16 g/mol

 

<span>TO get the mass percent, simply multiply the molar mass of each elements  with the number of the element divide by the molar mass of acetaminophen, that is:</span>

%C = [(12 * 8) / 151.163] * 100% = 63.50%

%H = [(1 * 9) / 151.163] * 100% = 5.954%

%N = [(14 * 1) / 151.163] * 100% = 9.262%

<span>%O = [(16 * 2) / 151.163] * 100% = 21.17% </span>

The boiling point of another member of this homologous series was found to be 309 KK. What is the likely molecular formula for t
Ganezh [65]

Answer: Pentane C5H12

Explanation:

The boiling point of a substance is simply defined as the temperature whereby a liquid's vapor pressure is equal to the pressure that is surrounding the liquid and hence, the liquid will changes into vapor.

The likely molecular formula for this compound is Pentane i.e C5H12 due to the fact that its boiling point is between Butane with formula C4H10 and Hexane with formula C6H14 boiling points.
