Answer:
malleable, strong, good conductor, ductile, shiny
Explanation:
I can't answer this question without knowing what the specific heat capacity of the calorimeter is. Luckily, I found a similar problem from another website which is shown in the attached picture.
Q = nCpΔT
Q = (1.14 g)(1 mol/114 g)(6.97 kJ/kmol·°C)(10°C)(1000 mol/1 kmol)
<em>Q = +6970 kJ</em>

<u>Answer:</u> The volume of stock solution of ammonia that is needed is 48.67 mL
<u>Explanation:</u>
To calculate the volume of stock solution, we use the equation:
where,
are the molarity and volume of the stock ammonia solution
are the molarity and volume of diluted ammonia solution
We are given:
Putting values in above equation, we get:
Hence, the volume of stock solution of ammonia that is needed is 48.67 mL
- The force acting on the box is 27N
- The acceleration of the car is 0.30 m/s²
- The object's mass is 2 kg
<h3>Newtons 2nd law </h3>
From Newton's second law,
F = ma
Where F is the force
m is the mass
and a is the acceleration
Q.1
Here, we are to determine the force acting on the box
m = 3 kg
a = 9 m/s²
Using the formula,
F = ma
F = 3 × 9
F = 27N
Hence, the force acting on the box is 27N
Q.2
Here, we are to determine the acceleration of the car
m = 780 kg
F = 235 N
Using the same formula,
F = ma
235 = 780 × a
a = 235 / 780
a = 0.30 m/s²
Hence, the acceleration of the car is 0.30 m/s²
Q.3
Here, we are to determine the object's mass
a = 5 m/s²
F = 10 N
Using the same formula,
F = ma
10 = m × 5
m = 10 / 5
m = 2 kg
Hence, the object's mass is 2 kg
