Answer:
Two moles of KClO3 decompose to form 5 moles of product.
Answer:
Measure the volume of water poured into a graduated cylinder, then place the object in the water and remeasure the volume. The difference between the two volume measurements is the volume of the object. Now simply divide the mass by the volume to calculate the density of the object.
Answer:
Explanation:
Given that:
The energy of the photon = 2.3 eV
Energy in eV can be converted to energy in J as:
1 eV = 1.60 × 10⁻¹⁹ J
So, Energy = 
Considering
Where,
h is Plank's constant having value 
c is the speed of light having value 
is the wavelength of the light being bombarded
Thus,
Also,
1 m = 10⁻⁹ nm
So,
Answer:
Yes
Explanation:
As the number of animals that eat plants increase, the number of plants decrease. This is because the animals are eating a larger and larger number of plants and reducing the population.
When the number of plants gets too low, the animals will not be able to survive, and they will start to decrease in numbers. In turn, the plants will increase again. Eventually, they will reach an equilibrium.
