Answer:
797.34 moles of H₂
Explanation:
From the question given above, the following data were obtained:
Number of molecules of H₂ = 4.8×10²⁶ molecules
Number of mole of H₂ =?
From Avogadro's hypothesis,
1 mole of H₂ = 6.02×10²³ molecules
With the above information, we can determine the number of mole of H₂ that contains 4.8×10²⁶ molecules as follow:
6.02×10²³ molecules = 1 mole of H₂
Therefore,
4.8×10²⁶ molecules = 4.8×10²⁶ / 6.02×10²³
4.8×10²⁶ molecules = 797.34 moles
Thus, 797.34 moles of H₂ contains 4.8×10²⁶ molecules.

Explanation:
Hello there!
In this case, when referring to single replacement reactions, it is crucial for us to figure out the formula of the starting reactants; thus, we know zinc is Zn and lead (IV) chloride is PbCl₄. In such a way, the reaction proceeds as follows:
Which must be balanced as shown below:
Regards!
Answer:
3.00 moles of Lithium bromide will be produced
Explanation:
The reaction that takes place is:
By looking at the reaction equation, we can see that<em> the reaction of 1 mol of lithium hydroxide (LiOH) produces 1 mol of lithium bromide (LiBr).</em> Thus, 3.00 moles of LiOH would conversely produce 3.00 moles of LiBr.
Answer:
Acceleration = 3.5 m.s⁻²
Explanation:
Definition:
The acceleration is rate of change of velocity of an object with respect to time.
Formula:
a = Δv/Δt
a = acceleration
Δv = change in velocity
Δt = change in time
Units:
The unit of acceleration is m.s⁻².
Acceleration can also be determine through following formula,
F = m × a
a = F/m
Given data:
Force = 35 N (N = Kg. m.s⁻²)
Mass = 10.0 Kg
a = ?
Formula:
a = F/m
a = 35 Kg. m.s⁻²/ 10.0 Kg
a = 3.5 m.s⁻²
Answer: Esta tendencia es tan regular que el poder de combinación, o valencia, de un elemento se definió una vez como el número de átomos de hidrógeno unidos al elemento en su hidruro. El hidrógeno es el único elemento que forma compuestos en los que los electrones de valencia están en la capa n = 1.
