Luego de utilizar la fórmula del volumen de un líquido encontramos que si el acohol tiene 450 gramos entonces su volumen es de
La fórmula del volumen de la densidad de un líquido es la siguiente:
Densidad= Masa / Volumen
Volumen =Masa / Densidad
Es conocido que la densidad del alcohol es 789 kg/m³, y como sabemos por dato que tiene 450gr el siguiente paso es la sustitución:
Volumen=0.45/ 789
Volumen = 0,00057 m³
Answer:
Please find the answer in the explanation.
Explanation:
Given that 16 g CH4 + 64 g 02 - 44 g CO2 + 36g H2O
To explain the law of conservation of mass and describe how the equation represents the law of conservation of mass, let me first start from law.
The law state that: mass can neither be created nor destroyed.
The mass of each element at the reaction side must be equal or the Same with the magnitude of mass at the product
The equation represents the law of conservation of mass because the mass of molecules at the right hand side is equal to or balance with the molecules at the left hand side. For example, the number of Oxygen, and othe elements are the at both side.
Some are fuel,chemicals,plastics,asphalt,and road oil.
15x 9.8 x .3 = 44.1
15 x 9.8 x 1 = 147
147 - 44.1 = 102.9J
102.9 J
Answer:
Explanation:
change in the volume of the gas = 5.55 - 1.22
= 4.33 X 10⁻³ m³
external pressure ( constant ) P = 1 x 10⁵ Pa
work done on the gas
=external pressure x change in volume
= 10⁵ x 4.33 X 10⁻³
=4.33 x 10²
433 J
Using the formula
Q = ΔE + W , Q is heat added , ΔE is change in internal energy , W is work done by the gas
Given
Q = - 124 J ( heat is released so negative )
W = - 433 J . ( work done by gas is negative, because it is done on gas )
- 124 = ΔE - 433
ΔE = 433 - 124
= 309 J
There is increase of 309 J in the internal energy of the gas.
