The factors that affect reaction rates are:
- surface area of a solid reactant.
- concentration or pressure of a reactant.
- temperature.
- nature of the reactants.
- presence/absence of a catalyst.
Hope this helps! Stay safe :))))
Because the elements have not yet then been discovered.
Hope this helps.
The solution would be like
this for this specific problem:
<span>Zn + 2HCl --> ZnCl2 +
H2 </span><span>
<span>Molar Mass Zinc - 65.38 g/mol </span>
<span>Molar Mass Zinc Chloride - 136.38 g/mol </span>
<span>Number of moles of zinc reacting = 0.600 g / 65.38g/mol =
0.00918 moles 0.00918
moles * 136.38 g/mole = 1.25 g ZnCl2 </span></span>
Answer = 1.25 grams of
zinc chloride

have any further questions, please don’t hesitate to ask again.</span>
Answer:
Mass of liquid unknown liquid = 10.4 g
Explanation:
Volume of liquid = 15 mL
Mass of liquid + graduated cylinder = 55.2 g
Mass of graduated cylinder = 44.8 g
Mass of unknown liquid = ?
Solution:
Mass of unknown liquid is calculated by subtracting the graduated cylinder mass from combined mass of liquid and graduated cylinder.
Mass of liquid = (Mass of liquid + graduated cylinder) - (Mass of graduated cylinder )
Mass of liquid = 55.2 g - 44.8 g
Mass of liquid = 10.4 g
So the mass of unknown liquid is 10.4 g.
