Answer:
a. 916.95K is final temperature of the gas
b. 3667.8K
Explanation:
a. We can solve the temperature of a gas when the volume is expanded three times using Gay-Lussac's law:
P₁T₂ = P₂T₁
<em>Where P is pressure,</em>
<em>And T is absolute temperature of 1, initial states and 2, final states of the gas.</em>
<em />
Initial pressure is 6.60 atm, initial absolute temperature is 32.5°C + 273.15K = 305.65K. Final pressure is three times initial pressure = 6.60atm*3 = 19.8atm.
Solving for final temperature:
P₁T₂ = P₂T₁
6.60atm*T₂ = 19.8atm*305.65K
T₂ =
916.95K is final temperature of the gas

b. Charle's law is the gas law that relates changes in volume and temperature of a gas:
V₁T₂ = V₂*T₁
If the volume is quadrupled: V₂/V₁ = 4:
T₂ = 4*916.95K
T₂ = 3667.8K
<span>When an ionic bond is formed between sodium (na) and chlorine (cl), the resulting molecule is called halite (salt). Ionic bonds involve the transfer of valence electrons. When this occurs between metals and non-metals, the metal loses an electron (becoming a cation) and the non-metal gains an electron (becoming an anion).</span>
Answer:
The formulas that will be used are:
Situation one:
The moon will be experiencing gravitational force in the form of centripetal force, so we equate the two formulas.
Gravitational force = GMm /r²
Centripetal force = mv²/r
Equating,
GMm/r² = mv²/r
v² = GM/r
The first scenario will use the formula v² = GM/r
Situation 2:
The second situation will use the simple distance over time formula for velocity, where the distance will be the circumference and the time will be in seconds.
v = 2rπ/t
Explanation:
The chemical formula tells us the mole ratio. CO2 = 1 CO2 molecule : 1 C atom : 2 O atoms. 1 C12H22O11 molecule: 12 O2 molecules : 12 CO2 molecules : 11 H2O molecules.
