The answer is A, light and heat energy.
Answer:
4) 0.5507 Mol Ar
5) 44.548 Mol AgNO3
6) 2.16107 Mol Li
Explanation:
Divide = grams to mol and mol to molecules
Multiply = molecules to mol and mol to grams.
3) 22 <em>g of Ar</em> 1 mol 22
-------------------- * ---------------------- = ------------ (turn to decimal) = 0.5507 Mol Ar
39.948 <em>g of Ar</em> 39.948
4) AgNO3 = (Ag; 39.948) (N; 14.007) (O^3; 48)
39.948 + 14.007 + 48 = 101.955
7.4 x 10^23 Mc 6.02 x 10^23 Mc
---------------------- * ------------------------- = 44.548 Mol AgNO3
1 mol
5)
15g 1 Mol 15
------- * ------------------- = --------- (turn to decimal) = 2.16107 Mol Li
6.941 g of Li 6.941
Answer:
atomic number
Explanation:
i'm assuming ur in eighth grade, bc same anyway good luck.
Answer:
333N
Explanation:
Once we have the object's mass, we can find the weight by multiplying it by the gravitational force, which it is subject to. Being that Mars has a gravitational force of 3.7m/s2, we multiply the object's mass by this quantity to calculate an object's weight on mars.
So an object or person on Mars would weigh 37.83% its weight on earth. Therefore, a person would be much lighter on mars. Conversely, a person is 62.17% heavier on earth than on Mars.
C. KOH + HBr → KBr + H₂O
Explanation:
The two equations above illustrates the conservation of matter. The law of conservation of matters states that
"in a chemical reaction, matter is neither created nor destroyed but transformed from one form to another".
By this law, we understand that the amount of a particular matter we are starting with should be the one we end with.
KOH + HBr → KBr + H₂O
Conserving Product Reactants
K 1 1
O 1 1
H 2 2
We can see that the amount on both sides are the same.
