Explanation: in a saturated/super saturated solution, more solute will not be able to dissolve.
<h3>
Answer:</h3>
A. 860 kg
<h3>
Explanation:</h3>
To answer the question we need to understand that;
- Mass refers to the amount of matter in an object.
- Weight, on the other hand, refers to the gravitational pull of an object to a given surface.
- Mass is measured using a spring balance.
We also need to know that;
- The mass of an object remains constant every where irrespective of the gravitational acceleration.
- Therefore, an object on the surface of the earth would have the same mass as on the surface of the moon.
- In this case; the mass of the car remains the same on the outer space as on the back yard.
Answer:
1)
Explanation:
the answer to you question Is 1)
Answer:
<h2>The answer is 2.5 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
density = 0.5 g/cm³
1 mL = 1 cm³
5 mL = 5 cm³
volume = 5 cm³
The mass is
mass = 0.5 × 5
We have the final answer as
<h3>2.5 g</h3>

Answer:
The furnace releases 1757280 J
Explanation:
We will do the conversion on two steps:
1- convert the kcal to cal
2- convert the cal to J
Step 1: converting kcal to cal
1 kcal is equivalent to 1000 cal. Therefore:
420 kcal is equivalent to 420*1000 = 420000 cal
Step 2: converting cal to J
We are given that:
<span>1 cal = 4.184 J
</span>Therefore:
420000 cal is equivalent to 420000 * 4.184 = 1757280 J
Hope this helps :)
. Hence, if we solve for the final Volume we get: 
. Now we know all the other variables; substituting we get that the final volume is 6.7 L (6.716 L ).
