Answer:
Molecules are made of two or more atoms
Molecules range in size
Molecules are made of atoms of the same element or different elements.
The required temperature of the sample of gas is 823K.
<h3>What is ideal gas equation?</h3>
Ideal gas equation gives idea about the behavior of gas at different condition & represented as:
PV = nRT, where
- P = pressure = 500 torr = 0.657 atm
- V = volume = 5.01 L
- R = universal gas constant = 0.082 L.atm / K.mol
- T = temperature = ?
- n = moles
Moles will be calculated as:
n = W/M, where
- W = given mass
- M = molar mass
Moles of Neon gas = 1g / 20.1g/mol = 0.049 mole
On putting all these values in the above equation, we get
T = (0.657)(5.01) / (0.049)(0.082) = 822.8 = 823 K
Hence required temperature of the sample is 823 K.

#SPJ1
Universal pH paper turns red if it is very strongly acidic, turns orange if it is strongly acidic, turns yellow if it is weakly acidic, green if it is weakly alkali and blue if it is strongly alkali.
Solution A will turn orange as it is strongly acidic
Solution B will turn blue as it is strongly alkali
Solution C will turn yellowish green as it is neutral
Answer:
CaCl2 (aq) + K2CO3(aq) ---------> CaCO3(s) + 2KCl(aq)
Explanation:
We have the reactants as calcium chloride and potassium carbonate. Recall that we are expecting that the reaction will yield a precipitate. We must keep that in mind as we seek to write its balanced chemical reaction equation.
So we now have;
CaCl2 (aq) + K2CO3(aq) ---------> CaCO3(s) + 2KCl(aq)
Recall that the rule of balancing chemical reaction equation states that the number of atoms of each element on the right side of the reaction equation must be the same as the number of atoms of the same element on the left hand side of the reaction equation.
