You mix 35mL of 0.54M NaI with 14mL of 0.84M Pb(NO3)2.
In order to accomplish work on an object there must be a force exerted on the object and it must move in the direction of the force. ... For the special case of a constant force, the work may be calculated by multiplying the distance times the component of force which acts in the direction of motion.
Answer:
a
Explanation:
the others are rude, and rather support this, while a helps to support the ending of white privlige
The moles of oxygen required to completely react with 1-mole acetylene is 2.5 mol.
The moles of reactant and product in a chemical reaction to the whole number ratio is given by the stoichiometric coefficient of the balanced chemical equation.
The unbalanced chemical reaction is
<span>Na (s) + H2O (g) yields NaOH (aq) + H2 (g)
By inspection,
There is 1 mole of Na in both sides
There is 2 moles of H in the left and 3 moles in the right side.
</span>There is 1 mole of O in both sides
<span>
We balance the reaction by:
</span>2Na (s) + 2H2O (g) yields 2NaOH (aq) + H2 (g)
The answer is 2
