In the reaction between a crushed antacid tablet and vinegar what gas is emitted

Pachacha [2.7K]

The answer is: emitted gas is carbon dioxide (CO₂).

Neutralization is is reaction in which an acid (in this example vinegar or acetic acid CH₃COOH) and a base (in this example soda)

Balanced chemical reaction of vinegar and antacid:

CH₃COOH(aq) + NaHCO₃(aq) → CH₃COONa(aq) + H₂O(l) + CO₂(g).

Sodium acetate (CH₃COONa) is a salt.

Sodium bicarbonate (NaHCO₃) is an antacid. Sodium bicarbonate is the active ingredient in baking soda.

Answer:

13. c) Net

14. a) Gravity

15. d) Watt

16. b) the speed will suddenly decrease.

Explanation:

13. The net force is combination of all individual forces.

14. When we sit on the chair , then gravitational force acts on our body due to our mass.

F = mg

here, F = force due to gravity , g = acceleration due to gravity and m= mass of the body

15.Power : It is the force acting per unit area .It is discovered by James Watt

$Power =\frac{force}{area}$

$Power =\frac{N}{m^{2}}$

Its unit is $Nm^{-2}$ .In honor of the Scientist , its unit is Watt.

Watt = $Nm^{-2}$

16. When the parachute first opens , the speed of the skydiver suddenly decreases because of the resistance offered by the air particles.(For more details look at the figure attached)

17. Transfer of momentum from one object to other is the law of conservation of momentum (NOT ENERGY).So the answer is False

 Law of Conservation of Momentum :  Total momentum of a system is conserved if no external force attack on it. Momentum can neither be created nor destroyed but transferred from one form to other.
