These are the characteristics that apply:

 - In a solution taste sour: which is consequence of the H+ concentration.

- Corrode metals: the H+ ion reacts with the metal producing a salt and water

-Produce hydronium ion in solution: as per the Bronsted - Lowry definition an acid is a substance that donates a proton, H+. This proton will react with H2O to form H3O+ (hydronium), as per this scheme: 

HA + H2O --> A(-) + H3O(+)

2. A loop of wire of area 0.7 m is moving into a 0.9 T magnetic field. If it takes 5
xenn [34]

Answer:

fem = -0.126 V

Explanation:

Faraday's law is

          fem =  - \frac{d \phi}{dt}

where the flow is

          Ф = B . A = B A cos θ

bold letters indicate vectors.

In this case, the normal to the area is parallel to the magnetic field, so the angle is zero and the cos0 = 1

           fem = - A \  \frac{dB}{dt}

in this case they indicate that to carry the loop from outside to inside the field in Δt = 5 s, so we can change them by variations

           fem = - A \frac{\Delta B}{\Delta t}

let's calculate

           fem = - 0.7 (0.9 -0) / 5

           fem = -0.126 V

How to know if a position time graph table is balanced or unbalanced
Goshia [24]

When balanced forces act on an object at rest, the object will not move. If you push against a wall, the wall pushes back with an equal but opposite force. Neither you nor the wall will move. Forces that cause a change in the motion of an object are unbalanced forces.
