Answer:
2:1
Explanation:
2 hydrogen to 1 mole oxygen
It’s called neutralization. The alkali has neutralized the acid by taking away the H+ ions and then turning them into water.
Answer:
253.85 L
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
C₃H₈ + 5O₂ —> 3CO₂ + 4H₂O
From the balanced equation above, 4 moles of water vapor were produced.
Finally, we shall determine the volume of the water vapor produced as follow:
Mole water vapor (n) = 4 moles
Pressure (P) = 1 atm
Temperature (T) = 500 °C = 500 °C + 273 = 773 K
Gas constant (R) = 0.821 atm.L/Kmol
Volume (V) =?
PV = nRT
1 × V = 4 ×0.0821 × 773
V = 253.85 L
Thus, the volume of water vapor obtained is 253.85 L
Answer:
there is no sound is space or because there in no gravity
Explanation:
44 neutrons and 35 protons. The number of neutrons you have is equal to the atomic mass minus the atomic number.
