Answer:
the correct answer is H2SO4 and HSO4-41
The balanced chemical equation Lead IV oxide decomposes
to yield lead II oxide and a colorless gas is
Pb3O4 → 3PbO + 1/2O2(g). The key in the balancing of
chemical reaction is to make sure that you got the exact chemical formula of
the substance that is reacting and the yielded product. After getting the
formula, identify first the hardest element/atom to be balanced such as Na, Zn,
Cl, etc. Then proceed to the easier ones such as O, H. Make sure to not the
atoms present in the molecule of the substance.
Answer:
6 atm
Explanation:
Using the formula P1V1=P2V2
P1= Initial Pressure
V1= Initial Volume
P2= Final Pressure
V2= Final Volume
And knowing that at stp gas will always be at 1 atm
250L(P2) = 1500
P2= 6 atm
Answer is: velocity of the bowling ball is 6.19 m/s.
Momentum is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction in three-dimensional space.
m(ball) = 35.2 kg; mass of a bowling ball.
p(ball) = 218 kg·m/s; momentum of a ball.
v(ball) = p(ball) ÷ m(ball).
v(ball) = 218 kg·m/s ÷ 35.2 kg.
v(ball) = 6.19 m/s; velocity of a bowling ball.
Answer:
Electronegativity, symbol χ, is a chemical property that describes the tendency of an atom to attract a shared pair of electrons (or electron density) towards itself. An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus.
