Mass<span> is the amount of matter in an object and </span>weight<span> is the measurement of the gravitational pull on an object. The </span>mass <span>of an object is the same no matter where it is, but the </span>weight <span>of an object changes with the location of that object.</span>
Answer:
780 watts
Explanation:
formula to find power when given amps and voltage
P = A x V
=6.50a x 120V
= 780 W (watts)
going down the the periodic table, the number of shells increases resulting in an obvious increase in the atomic radii of the elements
Answer: 
for the reaction is -90kJ
Explanation:
The balanced chemical reaction is,
The expression for Gibbs free energy change is,
![\Delta G=[n\times G_{products}]-[n\times G_{reactants}]](https://tex.z-dn.net/?f=%5CDelta%20G%3D%5Bn%5Ctimes%20G_%7Bproducts%7D%5D-%5Bn%5Ctimes%20G_%7Breactants%7D%5D)
Putting the values we get :
![\Delta G=[3\times G_f{S,rhombic}+2\times G_f{H_2O}]-[2\times G_f{H_2S}+1\times G_f{SO_2}]](https://tex.z-dn.net/?f=%5CDelta%20G%3D%5B3%5Ctimes%20G_f%7BS%2Crhombic%7D%2B2%5Ctimes%20G_f%7BH_2O%7D%5D-%5B2%5Ctimes%20G_f%7BH_2S%7D%2B1%5Ctimes%20G_f%7BSO_2%7D%5D)
![\Delta G=[(3\times 0kJ/mol)+(2\times -229kJ/mol)]-[(2\times -34kJ/mol) +(1\times -300kJ/mol)]](https://tex.z-dn.net/?f=%5CDelta%20G%3D%5B%283%5Ctimes%200kJ%2Fmol%29%2B%282%5Ctimes%20-229kJ%2Fmol%29%5D-%5B%282%5Ctimes%20-34kJ%2Fmol%29%20%2B%281%5Ctimes%20-300kJ%2Fmol%29%5D)
Thus for the reaction is -90kJ
Answer:
The correct answer is 101 feet.
Explanation:
To solve this problem, we need to remember the rules of significant figures. Any digit that is not zero is significant, and any zero is significant if it is between two non-zero digits or a trailing zero after the decimal point. Now, let's apply these rules to the options that are given:
1000 yards - Since the zeros are not after the decimal point or between two other digits, they are not significant. This means the only significant digit is 1, so there is only 1 significant digit.
1014 miles - All three of the non-zero digits are significant, and the 0 is significant in this case because it is between two other significant digits. Therefore, this number has 4 significant digits.
101 feet - The two 1's are significant because they are non-zero digits, and the zero is also significant because it is between the two 1's. Therefore, this number has 3 significant digits.
Thus, your answer is 101 feet.
Hope this helps!
