First,let's assume ideal gas behavior for simplicity. This is a special case because the volumes of the two states are equal. At constant volume, we can use the Gay-Lussac equation:
P₁/T₁ = P₂/T₂
(0.8)/(127+273) = (P₂)/(27+273)
Solving for P₂,
P₂ = 0.6 atm
<em>Thus, the answer is 0.6 atm.</em>
Answer:
The bolts will run out first, so these will limit how much product can be formed.
(option C is correct)
Explanation:
Step 1: Data given
Number of bolts = 5
Number of nuts = 12
ratio N:B = 2:1
Step 2
Since the ratio N:B is 2:1 we have 2 nuts for each bolt
When we have 2 bolts we have 4 nuts
When we have 3 bolts we have 6 nuts
When we have 4 bolts we have 8 nuts
When we have 5 bolts we have 10 nuts
We don't have more bolts, but there are still 2 nuts left. This means the bolts will run out first, so these will limit how much product can be formed.

Explanation:
Atomic radius can be defined as a measure of the size (distance) of the atom of a chemical element such as hydrogen, oxygen, carbon, nitrogen etc, typically from the nucleus to the valence electrons. The atomic radius of a chemical element decreases across the periodic table, typically from alkali metals (group one elements such as hydrogen, lithium and sodium) to noble gases (group eight elements such as argon, helium and neon). Also, the atomic radius of a chemical element increases down each group of the periodic table, typically from top to bottom (column).
Additionally, the unit of measurement of the atomic radius of chemical elements is picometers (1 pm = 10 - 12 m).
1. Li or K: the atomic radius of lithium is 167 pm while that of potassium is 243 pm.
2. Ca or Ni: the atomic radius of calcium is 194 pm while that of nickel is 149 pm.
3. Ga or B: the atomic radius of gallium is 136 pm while that of boron is 87 pm.
4. O or C: the atomic radius of oxygen is 48 pm while that of carbon is 67 pm.
5. Cl or Br: the atomic radius of chlorine is 79 pm while that of bromine is 94 pm.
6. Be or Ba: the atomic radius of berryllium is 112 pm while that of barium is 253 pm.
7. Si or S: the atomic radius of silicon is 111 pm while that of sulphur is 88 pm.
8. Fe or Au: the atomic radius of iron is 156 pm while that of gold is 174 pm.
