What is the density of an object with a mass of 180 grams and a volume of 45 cm3? Plz answer fast

4g/cm^3

Explanation:

The formula for density is mass divided by volume. 180g is your mass, 45cm^3 is your volume, divide the two to get your answer.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
