<span>Figure out the density. every metal has it's own. just fill a glass up to the top with water, and then carefully put the metal in. measure how much water is displaced (either by collecting the water or by measuring the glass afterwards),
then you will have the substance's density, because you have volume and it's measurement. </span>
Answer:
Exothermic, it obeys the law of conservation of energy
Explanation:
The reaction is an exothermic change. In this kind of change, heat is liberated to the surrounding. So the surrounding becomes hotter at the end of the heat change.
In chemical reactions that involves the loss of energy as heat, they obey the law of conservation of energy.
The law of conservation of energy states that energy is neither created nor destroyed but transformed from one form to another. In such reactions as this, chemical energy is transformed into heat energy.
Convection/Conduction effects out daily lives because we use microwaves, ovens, stoves basically things we use to cook and like the temperature of your house even ice because the coldness makes your drink colder
<span>measurement in Ci/Bq
the amount of radioactive materials released into the environment.
number of disintegrations of radioactive atoms in a radioactive material over a period of time</span>
Answer:
2.12atm
Explanation:
Boyle's Law: P1V1 = P2V2
Manipulate to solve for unknown: P2 = P1V1/V2
Substitute values: P2=(1.2atm)(4.6L)/2.6L
P2 = 2.1230769atm
Round to 3 sig figs to get 2.12atm
