Sergeu [11.5K]3 years ago

The principle of conservation of energy states that energy can neither be created nor destroyed, but can be changed from one form to another. The law of inertia on the other hand states that a body remains at a state of rest or motion on a straight line unless compelled by an external force. So i think that the answer is B, which is FALSE because the question is more related to the law of inertia(Newtons first law) than to the law of conservation of energy. Hope i helped.

explain how you can determine if a chemical reaction a single replacement reaction or a double replacement reaction
Kobotan [32]
However, there is one type of double-replacement reaction that we can predict: the precipitation reaction. A precipitation reaction occurs when two ionic compounds are dissolved in water and form a new ionic compound that does not dissolve; this new compound falls out of solution as a solid precipitate.

The atomic mass of an atom do not contain electrons because
Dimas [21]

Answer:

Electrons are so small that it does not affect the mass of atom .

Explanation:

Electrons are much smaller in mass than protons, weighing only 9.11 × 10^-28 grams, or about 1/1800 of an atomic mass unit. Therefore, they do not contribute much to an element's overall atomic mass.

A 10-gram aluminum cube absorbs 677 joules when its temperature is increased from 50°c to 125°
kotegsom [21]

Answer : The specific heat of aluminum is, 0.90J/g^oC

Solution : Given,

Heat absorbs  = 677 J

Mass of the substance = 10 g

Final temperature = 125^oC

Initial temperature = 50^oC

Formula used :

Q= m\times c\times \Delta T

or,

Q= m\times c\times (T_{final}-T_{initial})

Q = heat absorbs

m = mass of the substance

c = heat capacity of aluminium

T_{final} = final temperature

 T_{initial} = initial temperature

Now put all the given values in the above formula, we get the specific heat of aluminium.

677g= (10g)\times c\times (125-50)^oC

c=0.9026J/g^oC=0.90J/g^oC

Therefore, the specific heat of aluminum is, 0.90J/g^oC
