Answer:
4.332 millimoles of NaOH
Explanation:
Molarity (M) = moles per liter (mole/L); liters x moles/liter = moles
0.04332 L x 0.1 mole/liter = 0.004332 moles of NaOH (4.332 millimoles)
millimoles / milliliters = moles/liter = molarity (M).
4.332 millimoles / 50 milliliters = 0.08664 M HCl
In the Volumetric titration at the end point, moles of NaOH = moles of HCl
NaOH + HCl --> H2O + NaCl
Answer:
Hydrogen bond is formed only by the three highly electronegative elements- fluorine, oxygen and nitrogen.
Answer:
Explanation:
For work to be done, force must be applied to move an object in the direction of the applied force.
Work is the product of force and distance. Workdone describes a change of energy between places.
If we apply force to a body without moving it through a distance, no work is done.
Work is only done when force is applied to move or displace a body.
If we only apply force and no movement occurs, no work is done..
The unit of force is Joules.
The Law of Conservation of Mass states that matter cannot be created nor destroyed. It can only be transformed from one state or substance to another. This means that this law applies to both physical and chemical changes. In physical changes, the substance before and after the phase change still has the same mass. In chemical changes, the mass of reactants will always have the same mass of products and by-products.
