Balanced chemical reaction of hydrochloric acid and barium sulfite:
2HCl(aq) + BaSO₃(s) → BaCl₂(aq) + H₂O(l) + SO₂(g).
Balanced ionic reaction:
2H⁺(aq) + 2Cl⁻(aq) + BaSO₄(s) → Ba²⁺(aq) + 2Cl⁻(aq) + H₂O(l) + SO₂(g).
Net ionic reaction:
2H⁺(aq) + BaSO₄(s) → Ba²⁺(aq) + H₂O(l) + SO₂(g).
Answer:
False
Explanation:
The Strong Nuclear Force is defined as an attractive force between neutrons and protons which is responsible to hold the nucleus together.
Electrostatic force is the repulsive or attractive force between two electrically charged objects.
Strong nuclear force is always greater than electrostatic force but changes with the distance. Strong nuclear attraction keeps the nucleus of an atom together in a small space as well which is stronger than their electrostatic repulsion.
it is said that, the strong nuclear force is the strongest force in the universe.
Hence, the given statement is false.
Answer:
The correct answer is option C) "equilibrium price of peanut butter definitely falls".
Explanation:
The equilibrium price of a product is the market price established at a point where the quantity of products is equal to the quantity demanded by the consumers. In this case, the market of peanut butter is facing the decrease in the price of two substitutes of peanut butter: deli turkey slices and peanut brittle. As a result, the equilibrium price of peanut butter definitely falls since the quantity demanded by the consumers will certainly fall.
Answer:
Gravitational to Mechanical to electrical
Explanation:
In a hydropower dam, the gravitational potential energy is converted to mechanical energy which in turn produces electrical energy.
- The gravitational potential energy is due to the water overhead and the position of water inside the dam.
- The height and quantity of water determines the magnitude of the gravitational potential energy.
- Then, this energy is released when it falls on turbines and it drives them.
- As the turbine moves, mechanical energy is produced.
- The turbine is connected through a dynamo which produces a electric current by the turning action.
I could lift 3.06 x 10⁵ m high
<h3>Further explanation
</h3>
Energy is the ability to do work. Energy can change from one energy to another
Potential energy is the energy that an object has because of its position
The potential energy can be formulated:
Ep = m. g. h
E = potential energy of an object, joule
m = object mass, kg
g = gravity acceleration, m / s²
h = height of an object, m
energy of coal = 3.10⁶ J
mass = 1 kg
g = 9.8 m/s²
