Answer:
speed
Explanation:
Speed is the rate at which something moves. The speed of light is faster than the speed of sound.
Answer:
There will be produced a total of 50 mL of products (C2H4Cl2)
Explanation:
Step 1: Data given
Volume of Cl2 = 50 mL
Volume of C2H4 = 50 mL
Step 2: The balanced equation:
Cl2(g) + C2H4(g) → C2H4Cl2(g)
For 1 mol of Cl2 we need 1 mole of C2H4 to produce 1 mole of C2H4Cl2
Step 3: Calculate volume of C2H4Cl2
Since pressure, temperature are kept cosntant, we can calculate the final volume as following:
(5There will be produced a total of 50 mL of products (C2H4Cl2)0 mL Cl2) * (1 mol C2H4Cl2 / 1 mol Cl2) = 50 mL C2H4Cl2
D=m/v ⇒ v=m/d
d=density
m=mass
v=volume
Density (Fe)=7.86 g/cm³=7.86 g/ ml
m=4.18 Kg.(1000 g/1Kg)=4180 g
v=m/d=(4180 g) / (7.86 g/ml)=531.8 ml
v=531.8 ml*(1 dl / 100 ml)=5.32 dl
v=5.32 dl

Answer:
pH = 12.65
Explanation:
From the given information:
number of moles =mass in gram / molar mass
number of moles of KOH = mass of KOH / molar mass of KOH
number of moles of KOH = 0.251 g / 56.1 g/mol = 0.004474 mol
For solution :
number of moles = Concentration × volume
concetration = number of moles/ volume
concetration = 0.004474 mol / 0.100 L
concetration = 0.04474 M
We know that 1 moles KOH result into 1 mole OH⁻ ions
Therefore, Molarity of OH⁻ = 0.04474 M
Now,
pOH = -log[OH⁻]
pOH = -log (0.04474) M
pOH = 1.35
Similarly,
pH + pOH = 14
pH = 14 - pOH
pH = 14 - 1.35
pH = 12.65
