A good example of a scientific model would be a model of an atom. Since atoms are so tiny, you could make a larger model of it. That way you could study it and learn more about it. Maybe even find a new scientific discovery.
<h3>
Answer:</h3>
= 8.9 kg
<h3>
Explanation:</h3>
The pumpkin weighs 314 ounces
We want to calculate weight in kilograms
1 ounces is equivalent to 0.02835 kg
Therefore;
314 ounces will be equivalent to;
= 314 ounces × 0.02835 kg
= 8.902 kg
= 8.9 kg (2 d.p.)
Therefore; the mass of the pumpkin in kilograms is 8.9 kg
Answer:
gases (hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon and radon); one is a liquid (bromine); and a few are solids (carbon, phosphorus, sulfur, selenium, and iodine).

Answer:
HgS
Explanation:
In a 0.350g-sample there are 0.302 g of Hg. Then, there is 0.350 g - 0.302 g = 0.048 g of S. To calculate the empirical formula, we have to follow a series of steps.
Step 1: Calculate the percent composition
Hg: (0.302 g / 0.350 g) × 100% = 86.3%
S: (0.048 g / 0.350 g) × 100% = 13.7%
Step 2: Divide each percentage by the atomic mass of the element
Hg: 86.3 / 200.59 = 0.430
S: 13.7 / 32.07 = 0.427
Step 3: Divide the numbers by the smallest one
Hg: 0.430/0.427 ≈ 1
S: 0.427/0.427 = 1
The empirical formula is HgS.
