Answer:
B) Gamma
Explanation:
Gamma is by far the most powerful, and only one that can produce this much energy
Answer: 2.88×
atoms 
Explanation: First, using stoichiometry, we must convert this from grams to moles, then from moles to atoms.
1. For the first step, we should also look at the periodic table to find the molar mass of the compound, then use that as the denominator.
2. Now that it is converted to moles, we must convert it to atoms by multiplying it by Avogadro's number.
With this information, we know that there are 
total atoms in 0.680 grams 
.
I hope this helps! Pls give brainliest!! :)
Answer:
The final volume when pressure is changed is 126.1mL
Explanation:
Based on Boyle's law, in a gas the volume is inversely proportional to its pressure when temperature remains constant. The equation is:
P₁V₁ = P₂V₂
<em>Where P is pressure and V volume of 1, intial state and 2, final state.</em>
<em />
Computing the values of the problem:
350mmHg*200mL = 555mmHgV₂
126.1mmHg = V₂
<h3>The final volume when pressure is changed is 126.1mL</h3>
Where is the model? I do know salt water is a mixture though
