Answer:
168277.2 J
Explanation:
m = Mass of water = 600 g
c = Specific heat of water = 4.186 J/g°C
= Change in temperature of water = 
We know that the amount of heat lost = amount of heat gained
Heat lost by the iron bar is 168277.2 J.
Answer:
4.33 L
Explanation:
Assuming ideal behaviour and that all 0.300 moles of gas reacted, we can solve this problem using Avogadro's law, which states that at constant temperature and pressure:
Where in this case:
We <u>input the given data</u>:
- 2.16 L * 0.601 mol = V₂ * 0.300 mol
And <u>solve for V₂</u>:

The best answer among the choices is option D. New substances are being formed will best explain that this process is a chemical change. Although, it cannot be seen directly we knew that an acid and base will undergo neutralization reaction forming a salt and water. The heat given off by the reaction can be a parameter however it does not only happens for reactions. It can also happen when dissolving substances.
<h3><u>Answer;</u></h3>
<em><u> = 48,828.125 mi/hr²</u></em>
<h3><u>Explanation and solution</u>;</h3>
- <em><u>Centripetal acceleration is the rate of change of angular velocity. Centripetal acceleration occurs towards the center of the circular path along the radius of the circular path</u></em>.
- Centripetal acceleration is given by; <em>V²/r ; </em>
<em>V = 125 mi/h and r = 0.320 miles </em>
- <em>Thus; centripetal acceleration = 125²/0.320 </em>
=15625/0.320
<em><u> = 48,828.125 mi/hr²</u></em>
