Answer: m/s^2 (metre per second square)
Explanation:
Acceleration is the rate of change in velocity per unit time. The standard unit of measurement for acceleration is m/s^2 (metre per second square).
It can be derived from:
Acceleration = velocity / Time
Acceleration = (metre per second / second)
Acceleration = metre per second square.
In short form, it is written as m/s^2
Structural isomers, as the structure of the molecule is different
After ion exchange with zeolite in water filter to remove calcium by substitute natrium ion with calcium ion, the weight of zeolite become 1.9578 kg.
ion exchange calculation can be done by using basic stoichiometry if we know how the reaction of the ion exchange. In this case where zeolite with natrium ion will be exchanged with calcium. The reaction of exchange will be like this:
⇒ 
Calculate the molecule weight of both zeolite
Atomic weight data:
Na = 23 gram/mole
Si = 28 gram/mole
Al = 27 gram/mole
O = 16 gram/mole
Ca = 40 gram/mole
Molecule weight
= 142 gram/mole
= 278 gram/mole
Calculate mole from 2kg of zeolite with natrium :
2000 gram/ 142 = 14.0845 mole
Based on the stoichiometry, we got the mole of zeolite with calcium:
14.0845 mole x 1/2 = 7.0423 mole
Weight of zeolite after the ion exchanged with calcium:
7.0423 mole x 278 = 1957.8 gram = 1.9578 kg

Answer:
Density =1.27g/cm
Explanation:
Density is the mass per volume of a substance.
That is
Density = mass/volume
Given that mass = 14g
Volume = 11cm³
Therefore
Density = 14/11 g/cm³
Density =1.27g/cm³

The human activity creating water pollution and depletion are uses of fertilizers, detergents and chloro flouro carbon many other things.
<h3>What is water pollution?</h3>
Water pollution is defined as the contamination of water bodies, usually as a result of human activity, in such a way that their lawful uses are harmed.
The activities of human that creating water pollution are:
- Uses of fertilizers
- Harmful chemical in agriculture
- Detergents for washing clothes
- Wastes from industries
And depletion in the ozone layer are due to halogen source gases, which contain chlorine and bromine atoms, are produced by human activities. These emissions into the atmosphere eventually contribute to ozone depletion in the stratosphere.
Hence human activities are uses of fertilizers, detergents and many other things.
