AgCINaNO3
Ag + Cl + Na + NO3
AgCINa + NO3
AgCl + NaNO3

Answers

Answer 1
Answer:

Answer:

AgCl + NaNO₃

Explanation:

  • The reaction between silver nitrate and sodium chloride is an example of a double displacement reaction.
  • In a double displacement reaction compounds or salts reacts and exchange cations or anions to form new compounds or salts.
  • In this case, silver nitrate and sodium chloride exchange anions and cations to form silver chloride and sodium nitrate.
  • Therefore, the complete reaction is given by;

AgNO3 + NaCl → AgCl + NaNO₃

  • But since silver chloride is a precipitate, the reaction may also be an example of a precipitation reaction.

A shopper pushes a 7.32 kg grocery cartwith a 14.7 N force directed at
-32.7° below the horizontal.
What is the normal force on the cart?​

Answers

Answer:

The "normal force" on the "cart" 63.893 N.

Explanation:

To find normal force on the cart, use the equation

Normal force  = mg + F sinx,  

“m” being the object's mass,  

“g” being the acceleration of gravity,

“x” being the angle of the cart

Given values

M = 7.33 kg

F = 14.7 N

x=-32.7^(\circ)

\mathrm{g}=9.8 \mathrm{m} / \mathrm{s}^(2) \text { (g is referred to as the acceleration of gravity. Its value is } 9.8 \mathrm{m} / \mathrm{s}^(2) \text { on Earth }

Substitute the values in above equation

Normal force = (7.33 × 9.8) + 14.7 sin(-32.7°)

Normal force = 71.834 + 14.7 × (-0.5402)

Normal force = 71.834 - 7.94094

Normal force = 63.893 N

The "normal force" on "the cart" 63.893 N.

The normal force on the cart is 79.7 N

Explanation:

In order to find the normal force, we have to analyze the forces acting on the cart on the vertical direction.

In the vertical direction, we have the following forces:

The weight of the cart, downward, of magnitude , where m is the mass of the cart and g is the acceleration of gravity

The normal force on the cart, upward, we indicate it with N

The component of the pushing force acting in the vertical direction, downward, of magnitude , where F is the magnitude of the force and is the angle of the force with the horizontal

Therefore, the equation of the forces on the cart in the vertical direction is:

where the net force is zero since the cart is balanced in the vertical direction. We have:

We take the angle as positive since we are already considering the downward direction in the equation.

Substituting and solving for N, we find the normal force:

Describe how the resistance of the filament lamp changes as the current through it increases.

Answers

This heats up when an electric current passes through it, and produces light as a result. The resistance of a lamp increases as the temperature of its filament increases. The current flowing through a filament lamp is not directly proportional to the voltage across it.

Explain why the phrase "by ordinary means" was added to the Law of Conservation of Energy

Answers

The phrase "by ordinary means" was added to the Law of Conservation of Energy because kind to be expected in the normal order of events.

What is mean byLaw of Conservation of Energy and who proposed it?

  • Law of Conservation of Energy law, first proposed and tested by Émilie du Châtelet, means that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another. For instance, chemical energy is converted to kinetic energy when a stick of dynamite explodes
  • The conservation of energy formula goes Ki+Ui=Kf+Uf. U is potential energy and K is kinetic energy..
  • The laws of conservation of energy, momentum, and angular momentum are all derived from classical mechanics.
