An object with a mass of 3.5 g raises the level of water in a graduated cylinder from 25.1 mL to 31.7 mL. What is the density of
vodomira [7]

density of the object = 0.53 g/mL

Explanation:

First we need to find the volume of the object which is equal to the rise of the water in the graduated cylinder:

volume = 31.7 - 25.1 = 6.6 mL

Now we calculate the density of the object using the following formula:

density = mass / volume

density = 3.5 g / 6.6 mL

density = 0.53 g/mL

Energy is stored in chemical bonds during photosynthesis.

During photosynthesis, the radiant energy from the sun is converted to chemical energy in carbohydrates.

Inorganic materials in the form of carbon dioxide and oxygen combine to form carbohydrates in the presence of radiant energy according to the equation below:

6CO_2 + 6H_2O ---> C_6H_1_2O_6 + 6O_2

The energy is thus, stored in chemical bonds in the carbohydrate and this is what is oxidized during respiration to release the locked energy.

A gas is contained in a thick-walled balloon. When the pressure changes from 45.0 bar to 96.0 bar, the volume changes from 1.20
notsponge [240]

P1 * V1 ÷ T1 = P2 * V2 ÷ T2  

45 * 1.20 ÷ 314 = 96 * V2 ÷ 420  

30,144 * V2 = 22,680  

V2 = 22,680 ÷ 30,144  

The new volume is approximately 0.75 liter.

I hope I helped
