They have you the equation and everything to plug in. You barely have to do anything here, I’m unsure why you’re even asking.
Force = mass*acceleration
20N = 10kg*a
a = 2 m/s^2
We can exemplify with H2O (water)
H= nonmetalic
O= Nonmetalic
A bond with nonmetalic and nonmetalic is covalent bond.
Hope it helps!!
#MissionExam001
The balanced reaction equation for the combustion of butane is as follows;
C₄H₁₀ + 13/2O₂ ---> 4CO₂ + 5H₂O
the limiting reactant in this reaction is C₄H₁₀ This means that all the butane moles are consumed and amount of product formed depends on the amount of C₄H₁₀ used up.
stoichiometry of C₄H₁₀ to H₂O is 1:5
mass of butane used - 6.97 g
number of moles - 6.97 g / 58 g/mol = 0.12 mol
then the number of water moles produced - 0.12 mol x 5 = 0.6 mol
Therefore mass of water produced - 0.6 mol x 18 g/mol = 10.8 g
Answer:
Explanation:
Molarity of acid(volume of acid)(# of H ions)= molarity of base(volume of base)(# of OH ions)
M(v)(#)=M(v)(#)
sulfuric acid sodium hydroxide
H2SO4 NaOH
(3)(11.6)(2)=M(25)(1)
M=2.784
The correct answer is 2.99 helium atoms.
I hoped this helped!
