Answer:
704.25 atm
Explanation:
From the ideal gas equation
PV = nRT
P = nRT/V
Molar volume (V/n) = 34.7 cm^3/mol, n/V = 1/34.7 = 0.0288 mol/cm^3
R = 82.057 cm^3.atm/mol.K
T = 25°C = 25+273 = 298 K
P = 0.0288 × 82.057 × 298 = 704.25 atm
Answer:
3
Explanation:
10.0 has 3 significant figures
Answer:
The difference is 293.15 Kelvin.
Explanation:
Given data:
Temperature difference of matter = 20°C
Temperature difference of matter in kelvin = ?
Solution;
Formula:
0°C +273.15
now we will put the values instead of 0.
20°C + 273.15 = 293.15 K
Thus, the temperature difference between two sample is 293.15 K.
Actually when we burn metal salts, we cannot actually
really see distinct lines to appear because in reality, they are not really
visible to the human eye. There is only a certain range of wavelength of light that
our eyes can see.
To state in other way, some metal salts will give off light which has wavelengths that are outside of the visible region of the electromagnetic spectrum.<span> </span>
