Scientific notation is always expressed as a number between 1 and 10 not including 10 followed by 10 to a power.

1 ≤ x < 10

7.6 * 10^2 is the correct answer. You used one of the powers to get to a number between 1 and 10

0.76 * 10 = 7.6 That leaves you with 2 tens.

1. Explain Hydrogen peroxide, H 2 O 2 properties and decomposition reaction.
Len [333]

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.

Answer: HOPE IT HELPS! PLS MARK AS BRAINLIEST

Explanation: The respiratory pigment, haemoglobin in red blood cells have a very high affinity of oxygen. It combines with oxygen to form oxyhaemoglobin and thus oxygen is carried from lungs to various body parts. Carbondioxide is highly soluble in water so it is mostly transported  in dissolved form in our blood plasma.
