Answer:

\boxed {\boxed {\sf 32 \ kilometers}}

Explanation:

Distance is the product of speed and time.

d=s*t

The speed is 8 kilometers per hour and the time is 4 hours.

s= 8 \ km/hr \\t= 4 \ hr

Substitute the values into the formula and multiply. Note that the hours will cancel when multiplied.

d= 8 \ km/hr * 4 \ hr

d= 32 \ km

Mr. Evans traveled <u>32 kilometers.</u>

Answer:

32 km.

Explanation:

Distance = speed × time

We know that Mr. Evans is riding his bicycle at an average of 8km/hr, or 8 kilometers per hour. He is riding his bike for 4 hours, so we will need to multiply according to the formula.

8 × 4 = 32

The answer to the question is 32 kilometers.

A sample of ideal gas is in a sealed container. The pressure of the gas is 485 torr , and the temperature is 40 ∘C . If the temp
Fantom [35]

Answer:

537.68 torr.

Explanation:

  • We can use the general law of ideal gas:<em> PV = nRT.</em>

where, P is the pressure of the gas in atm.

V is the volume of the gas in L.

n is the no. of moles of the gas in mol.

R is the general gas constant,

T is the temperature of the gas in K.

  • If n and V are constant, and have different values of P and T:

<em>(P₁T₂) = (P₂T₁).</em>

P₁ = 485 torr, T₁ = 40°C + 273 = 313 K,

P₂ = ??? torr, ​T₂ = 74°C + 273 = 347 K.

∴ P₂ = (P₁T₂)/(P₁) = (485 torr)(347 K)/(313 K) = 537.68 torr.

A compound is found to contain 38.65 % carbon, 16.25 % hydrogen, and 45.09 % nitrogen by mass. what is the empirical formula for
iren [92.7K]

The molar mass of carbon is 12, hydrogen is 1, and nitrogen is 14, hence the ratio are:

 

C = 38.65 / 12 = 3.22

H = 16.25 / 1 = 16.25

N = 45.09 / 14 = 3.22

 

Divide the three by the lowest ratio which is 3.22:

 

C = 3.22 / 3.22 = 1

H = 16.25 / 3.22 = 5

N = 3.22 / 3.22 = 1

 

So the empirical formula is:

CHN

PAP Physical Studies<br><br> How can you remember the periodic table?
siniylev [52]
Break down the table into smaller sections. Memories period by period or if you like by group (like halogens or noble gases).
Just say the elements in order everyday 1-10 then when you get those 11-20 and continued.
