Answer:
The answer is C3H8 + 5O2 → 3CO2 + 4H2O .
Ranking of the atom from highest to lowest is as follows:
Highest
Arrow = from outer edge to center
2nd Highest
Arrow = second closest ring to the outer edge to center
3rd Highest
Arrow = middle circle to center
Lowest
Arrow = outer edge to middle circle
Answer:
Geosphere
Explanation:
Geosphere sometimes called as lithosphere starts from the surface of the earth and lies till crust. This part of the earth contains rocks and minerals.
This portion of the earth includes sediments,mountains and rock. The natural resources that is available to the human brings lies in geosphere.
Atomic number (19) measures how many protons it has
mass number (39.098) average of all the isotopes for potassium. as well as the number of protons + neutrons
Answer:
The answer to your question is 510.7 kJ
Explanation:
Data
Q = ?
Volume = 2 L
Temperature 1 = T1 = 19°C
Temperature 2 = T2 = 80°C
Specific heat = 4.186 J/kg°C
Density of water = 1 g/ml
Equation
Q = mC(T2 - T1)
Process
1.- Calculate the mass of water
mass = density x volume
mass = 1 x 2000
mass = 2000 g
2.- Substitute values in the Heat formula
Q = (2000)(4.186)(80 - 19)
-Simplification
Q = (2000)(4.186)(61)
-Result
Q = 510692 J or 510.7 kJ
