Answer:
Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst are the four main factors that affect reaction rate.

Answer:
Here's what I find
Explanation:
Heisenberg observed that if we want to locate a moving electron, we must bounce photons off it.
However, this makes it recoil. By the time the photon returns to our eye, the electron will no longer be in the same place.
He concluded that there is a limit to the precision with which we can simultaneously measure the position and speed (momentum) of a particle.
The more precisely we know the electron's speed, the less precisely we know its position and vice versa.
The uncertainty in the product of the two values cannot be less than a fixed small number.
Answer:
v = 37.9 ml
Explanation:
Given data:
Mass of compound = 1.56 kg
Density = 41.2 g/ml
Volume of compound = ?
Solution:
First of all we will convert the mass into g.
1.56 ×1000 = 1560 g
Formula:
D=m/v
D= density
m=mass
V=volume
v = m/d
v = 1560 g / 41.2 g/ml
v = 37.9 ml
