Answer:
P = 22000 kg. m/s
Explanation:
Given data;
Mass of elephant = 2000 Kg
Velocity = 11 m/s
Momentum = ?
Solution:
Momentum is the product of mass and velocity of an object.
It can be calculated from given formula:
P = mv
P = momentum
m = mass
v = velocity
Now we will put the values in formula.
P = 2000 Kg × 11 m/s
P = 22000 kg. m/s
Hello!
A substance that could be found in air, water or soil that is harmful to humans or animals is a Pollutant.
The other substances cannot be found in air, water or soil. Fossil fuels can only be found in soil, smog can only be found in the air, and carbon dioxide can be found in the water or air.
Pollutants are substances that have harmful effects and damage the environment. Some examples of pollutants are Carbon Monoxide (air), Lead (soil) and Insecticides (water).
Have a nice day!
The answer is 6. proton substance with only one type of atom.
Answer:
2 K(s) + Cl₂ (g) --> 2 KCl(s)
Explanation:
Potassium will just be K
Chlorine gas is part of BrIClHOF, which are diatomic gasses. So Cl₂
Looking at the periodic table potassium K has an ion charge of +1 and chlorine Cl has an ion charge of -1, so in a balanced compound they will be written as KCl
Balancing the amounts of each will lead to 2 K(s) + Cl₂ (g) --> 2 KCl(s)
