By definition, when you divide a full rotation into 360 parts, a degree is the angle spanned by one of those parts. In contrast, on the temperature scale, a “degree” is the temperature “step” you get when you divide the temperature difference between the freezing and boiling points of water into 100 equal parts.
Answer:
See below.
Explanation:
I'll do the second row for you the other 2 are done in exactly te same way.
B. Area of 1 side of cube = 2*2 = 4.
Surface area = 4*6 = 24
Volume = 2*2*2 = 8.
Surface area / volume = 24/8 = 3.
Ratio of Suface Area to Volume = 24 : 8 = 3 : 1. (divide both by 8)
Answer:
8
Explanation:
the number before the abbrviation for calcium (Ca) shows how many calcium there is.
The number of mole of the gas present in the sample which occupies a volume of 350 mL at 25 °C and 1 atm is 0.0143 mole
From the question given above, the following data were obtained:
Volume (V) = 350 mL = 350 / 1000 = 0.35 L
Temperature (T) = 25 °C = 25 + 273 = 298 K
Pressure (P) = 1 atm
Gas constant (R) = 0.0821 atm.L/Kmol
<h3>Number of mole (n) =? </h3>
With the application of the ideal gas equation, the number of mole of the gas present in the sample can be obtained as follow:
<h3>PV = nRT </h3>
1 × 0.35 = n × 0.0821 × 298
0.35 = n × 24.4658
Divide both side by 24.4658
n = 0.35 / 24.4658
<h3>n = 0.0143 mole </h3>
Therefore, the number of mole of the gas present in the sample is 0.0143 mole
