PH = -log[H₃O⁺]
= -log(<span>3.5×10</span>⁻⁴)
= 3.46
Hence the pH of the given agricultural product is 3.46 which means the product is acidic.
If the pH > 7, then the solution is basic.
If the pH < 7, then the solution is acidic.
If the pH = 7, then solution is neutral.
The volume of copper : 3.24 ml
<h3>Further explanation

Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
With the same mass, the volume of objects that have a high density will be smaller than objects with a smaller type of mass
The unit of density can be expressed in g/cm³ or kg/m³
Density formula:
ρ = density
, g/cm³ or kg/m³
m = mass
, g or kg
v = volume
, cm³ or m³
A common example is the water density of 1 gr / cm³
The density of copper : 8.96 gr/ml
mass of copper : 29 g
then the volume :

Answer:
Nitric acid reacts with sodium carbonateto form sodium nitrate, carbon dioxide and water. 2HNO3+Na2CO3→2NaNO3+CO2+H2O.
Answer:
C.It remains at rest or moves at constant speed in the same direction.
Explanation:
First, remember the Newton's 1st law of motion which states that the object at rest will remain at rest and that in motion will stay in motion with the same speed and same direction unless acted by unbalance forces.
Balanced forces on an object occur when two forces at act on an object are equal in size and act in opposite direction. In this case, a stationary object will stay at rest while an object moving will continue to move at the same speed and same direction.
An object acted by balanced forces is said to be at equilibrium, thus the state of motion will be maintained.The object will not accelerate. A good example of an object acted by balanced forces is an object at rest or in constant motion such as a car that stopped at red-light signal or a car travelling at a constant speed.
