It would be Magnesium = 1 atom, Oxygen = 2 atoms, Hydrogen = 2 atoms. It has 5 atoms total. There is 1 magnesium and you multiply each element by the the 2 outside the parenthesis to get 2 oxygen and 2 hydrogen.
Answer:
the answer would be Halogens
Answer:
I'm pretty sure its stimulus
Quantitative is anything that is relating to a number value. Think “quantity”
Example:
1. There are 5 ml of water
2. There are 3 beakers
3. It takes 30 minutes for the reaction
Qualitative is about characteristics that can be described
Example
1. The liquid is green
2. The solution turned into a gas
3. Bubbles were produced
Answer:
1) Hydrogen Peroxide. Hydrogen Peroxide (H2O2) is a colourless liquid that resembles water in many respects. Its physical properties are very similar to those of water, except that it is 40% denser. ... The single bond between the two oxygen atoms is weak, so that H2O2 readily fragments into either H and HO2 or two OHs.
2) Is human activity warming the Earth or do recent signs of climate change signal natural variations? In this feature article, scientists discuss the vexing ambiguities of our planet's complex and unwieldy climate.
a) The Water Cycle. ... The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation.
b) Carbon is an essential element for life on Earth. Every living organism has carbon compounds inside each of its cells, such as fats and proteins. The carbon cycle shows how atoms of carbon can exist within different compounds at different times and be recycled between living organisms and the environment.
