The answer is : B. age of material
thermal Energy is an energy that come from heat, which caused by the movement of the particles in that substance. The faster it moves, the more energy it produced, which is affected by the change of temperature, its composition, and its size
To determine the quantity of pure CaCl2 from the given amount of CaCl2.9H2O, we use the ratio of CaCl2 to CaCl2.9H2O. From the formula the ratio would 1 is to 1 We calculate as follows:
7.5 g CaCl2.9H2O (1 mol / 273.1215 g) ( 1 mol CaCl2 / 1 mol CaCl2.9H2O ) ( <span>110.98 g / 1 mol ) = 3.05 g CaCl2
Hope this answers the question. Have a nice day. Feel free to ask more questions.</span>
Answer:
Mass, m = 37900 grams
Explanation:
Given that,
The density of a brand of gasoline is 0.737 g/mL at 25°C
We need to find mass of gasoline would fill a 13.6 gal tank.
Density is defined as mass per unit volume.
We know that, 1US gal=3.78L
So,
1US gal = 3785.41 mL
13.6 US gal = 51481.6 mL
So,
or
m = 37900 g (in three significant figures)
So, the mass of the gasoline is 37900 grams.
The answer you are looking for would be a colliod. Hope this helps have a great day!!
