Answer:
I think that:
The tendency of an object to resist changes in motion: inertia
Attractive force:gravity
And everything else is right
Explanation:
I am not a physicist
But I passed physics with an A
I believe the answer is A. <span>make a softer sound because the shark will not hear the softer signal.
</span><span>
I say this becasue "</span><span>Some of the sounds dolphins make are outside the range of human hearing." So that means the the dolphins speak at a higher wavelength then us humans and we can't hear it so they could use that to their advantage and speak at a height wavelength to each other when sharks are near.
I could be wrong, but I think the answer is A. </span>
Because all the compounds are at the same concentration, the one that can produce more particles in solution will be the one that will raise the boiling point the most.
<span>A. 2.0 M (NH4)3PO4 will produce 4 particles per molecule formula</span>
0.72 mole of oxygen would produce 320.4 kJ of heat.
<u>Explanation:</u>
CH₄ (g) + 2O₂ (g) → CO₂ (g) + 2H₂O (ℓ) + 890kJ
According to the equation,
2 moles of O₂ produces 890 kJ of heat
So, 0.72 moles of O₂ will produce:
Therefore, 0.72 mole of oxygen would produce 320.4 kJ of heat.
Answer:
Endothermic
Exothermic
Endothermic
Exothermic
Exothermic
Exothermic
Explanation:
Endothermic is when a reaction absorbs heat.
Exothermic is when a reaction releases heat.
