Answer:
"True"
Explanation:
Breathing released by humans is naturally acidic. When humans inhale, there are also dangerous toxic substances such as carbon dioxide in the lungs inside the human body, which are neutralized with the help of HCl hydrochloric acid, but due to hydrochloric acid, the breath that man leaves becomes acidic.
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:
Characteristics of Group
Explanation:
The elements of a group show similar chemical properties but there is a gradual variation in the physical properties of the elements in a group.
In general, SOLUBILITY<span> is an ability of a substance to dissolve. In the process of dissolving, the substance which is being dissolved is called a </span>solute<span> and the substance in which the solute is dissolved is called a </span>solvent.<span> A mixture of solute and solvent is called a </span><span>solution.</span>
Answer:
4
Explanation:
your chosen answer is right as unsaturated mean contains double bond and 1st and 3rd is Wrong as Carbon only can have 4 bonds and 2nd is Wrong as it is saturated.
hope this helps :)
