Answer: Two cold air masses surround a warm air mass during a warm front, but a cold air mass moves against a warm air mass during an occluded front.
Answer:
The answer is C. AB is an intermediate; therefore the rate law is determined from the reactants in the previous step.
I just took the test and C. was correct. Please mark me as brainliest!
Answer:
C₆H₈O₇ = 192 g/mol
Explanation:
Molar mass is the sum of the atomic weight of the atoms present in compound.
Formula of citric acid:
C₆H₈O₇
Atomic weight of hydrogen = 1 amu
Atomic weight of carbon = 12 amu
Atomic weight of oxygen = 16 amu
C₆ = 6 × 12 = 72 g/mol
H₈ = 8 × 1 = 8 g/mol
O₇ = 7 × 16 = 112 g/mol
C₆H₈O₇ = 72 g/mol + 8 g/mol + 112 g/mol
C₆H₈O₇ = 192 g/mol
Answer:
The answer to your question is Cm = 2.093 J/kg°C
Explanation:
Data
mass metal = mass of water
Δ water = 5°
Δ metal = 10°
Cm = ?
Cw = 4.186 J/Kg°C
Formula
for metal for water
mCmΔTm = mCwΔTw
Cancel mass of metal
Cm ΔTm = CwΔTw
solve for Cm
Cm = (CwΔTw) / ΔTm
Substitution
Cm = (4.186 x 5) / 10
Simplification
Cm = 20.93 / 10
Result
Cm = 2.093 J/kg°C
