Empirical formula is the simplest way the molecular formula can be wrote so here 7 goes into all of these so it would be CH2O
Answer:
because it is type of tht a solid
Compounds are made up of elements that exist in a fixed proportion. These elements are composed of atoms. Now, the atom has subatomic particles (proton, neutron and electrons), however, these particles lack the ability to take part in chemical reactions by themselves; the smallest unit of a compound that can take part in a chemical reaction, therefore, is an ATOM.
Thus, an AT<span>OM is the smallest unit of a compound that retains the unique properties of the compound</span>
Explanation:
measuring the change of temperature when 2 liquids are mixed
The temperature of the gas sample is 813 K.
<u>Explanation:</u>
We have to use the ideal gas equation to find the temperature of the gas sample.
The ideal gas equation is PV = nRT
Pressure, P = 429 mm Hg = 0.56 atm
Volume, V = 560 mL = 0.56 L
R = gas constant = 0.08205 L atm mol⁻¹K⁻¹
Mass = 0.211 g
Molar mass of carbon di oxide = 44.01 g / mol
Moles, n = 
= 0.0047 mol
Now, we have to plugin the above values in the above equation, we will get the temperature as,

T = 
= 813 K
So the temperature of the gas sample is 813 K.
