Answer:
273.9 fathom
Explanation:
Fathom (ftm) and rod are the units of length used in the imperial and the U.S. customary systems.
Fathom is an unit used for the measurement of depth of water. It is equal to 1.8288 m.
Rod, also known as perch or pole, is equal to 5.0292 m.
∵ 1 fathom = 0.364 rod
and 1 rod = 2.75 fathom
∴ 99.6 rod = 99.6 × 2.75 fathom = 273.9 fathom
<u>Therefore, maximum depth of Lake Tahoe = 99.6 rod = 273.9 fathom</u>
Answer: of PABA is 0.000022
Explanation:
cM 0 0
So dissociation constant will be:
Give c= 0.055 M and = ?
Putting in the values we get:
Thus of PABA is 0.000022
Answer:
i think the answer is D.
Explanation:
for the chemical equation in all the other answers are true so therefor d is not.
Answer:
K.E = 0.5 j
Explanation:
Given data:
Mass of ball = 50 g (50/1000 =0.05 kg)
Speed of ball = 4.5 m/s
K.E of ball = ?
Solution:
Formula:
K.E = 1/2 m.v²
Now we will put the values in formula
K.E = 1/2 (0.05 kg) (4.5 m/s)²
K.E = 1/2 (0.05 kg) 20.25 m²/s²
K.E = 1/2 (1.0 kg. m²/s²)
K.E = 0.5 kg. m²/s²
j = kg. m²/s²
K.E = 0.5 j
Answer:
Zn. + 2 HCl ----------> ZnCl2. + H2
Explanation:
Mass of Zn in mole = 3.27/ 65.38= 0.050010.... mol
Mass of HCl in mole = 3.3/ 73= 0.044....mol
Hence, limiting reagent is HCl
Molar mass of ZnCl2= 136.38g
Let mass of ZnCl2 be x
x = 3.3*136.38÷ 73 = 6.165...
So, the mass of ZnCl2 is 6.17 g
