Since your multiplying by the same number, 104, both terms, you can group them like this:
104(1.26+2.50)
104(3.76)
391.04
Knowing that scientific notation needs to be a number x, that’s greater or equal to 1, and less then 10.
3.9104 * 10^2
Answer:
wood burning and cookies baking
Explanation:
took the test <333
Potassium reacts with bromine to produce Potassium Bromide, because bromine has a (-) charge while potassium has a (+) charge. Bromine needs to gain one more electron to have a noble gas configuration or 8 valence electrons, & potassium needs to lose one so they make a transference of electrons in an ionic bond.
Answer:
one mole of oxygen will produce 
moles of water
Explanation:
The balanced chemical reaction is as follows -
2 C2H2 + 5 O2 --> 4 CO2 + 2 H2O
As we can see in this reaction
5 mole of oxygen (on the reactant side) will produce 2 mole of water (on the product side)
Hence, one mole of oxygen will produce 
moles of water
