Answer:
The first set is a solution, the second is not.
Step-by-step explanation:
Testing by filling in the numbers into the equation:
(1, 1.5): x=1, y=1.5
⇒ 1.5 =? 
· 1 + 
⇒ 1.5 =? +
⇒ 1.5 =? 
⇒ 1.5 =? 1.5 ⇒ Correct: is indeed solution to the equation
(12, 4): x=12, y=4
⇒ 4 =? · 12 +
⇒ 4 =? 
+
⇒ 4 =? 
⇒ Incorrect: this is not a solution for the equation
Answer:
0.670. M
Step-by-step explanation:
Molarity can be expressed like this:
molarity
= number of moles
/volume (L)
We know the volume, which is 2.37 L
, but we need to find the number of moles. We can do this by dividing 67.3 g by the molar mass of L
i
C
l
:
number of moles =
mass of sample
/molar mass
number of moles = 67.3 g
/(6.94 + 35.45) g/mol =
67.3 g
/42.39 g/mol
number of moles = 1.59 mol
molarity
=
1.59 mol
/2.37 L
= 0.670. M
Answer:
(Thermometer B reading - Thermometer A reading)
Step-by-step explanation:
The thermometer reading aren't given in the question.
However, hypothetically.
The difference between two temperature values (morning and evening values) would be :
Temperature in the evening - morning temperature
Therefore,
If ;
Thermometer A reading = morning temperature
Thermometer B reading = evening temperature
Difference in the temperature :
(Thermometer B reading - Thermometer A reading)
<span>The correct answer is: Option (C) $1393.21
Explanation:
At the beginning of the Second year, the total balance would be:
$1200 + ($1200 * 7.75 / 100) = $1293
At the beginning of the Third year, the total balance would be:
$1293 + ($1293 * 7.75 / 100) = $1393.21 (Option C)</span>
C- capacity
c/3+2950=3c/4 the common denominator is 12.
4c+2950*12=3c*3
4c+35400=9c
35400=9c-4c
35400=5c
c=7080 ml =7.08l
