What is the charge on an ion that has an atomic number of 16 and contains 14e-?
lora16 [44]
The answer would be 2+ since the atomic number represents how many protons are in the element. In this case, there are 16 protons, but only 14 electrons, which means there are an additional 2 protons, hence the 2+ charge on the ion.

Which two changes of state can occur when a substance gains thermal<br> energy?
irinina [24]

Answer:

Adding enough thermal energy to a substance can cause a change of state to occur. The change of state from a solid to a liquid is called melting. When energy is added to an ice cube, the ice particles speed up as energy is absorbed. When the particles move fast enough, the solid ice melts and becomes liquid water

Brandon is traveling in France. He weighs himself at a health club because he is concerned that he has eaten too many croissants
anastassius [24]

<u>Answer:</u>

<u>For a:</u> Yes, he has gained weight.

<u>For b:</u> The number of onions required is 1.

<u>Explanation:</u>

  • <u>For a:</u>

We are given:

Weight of Brandon checked earlier = 183 lb

Converting this into kilograms, we use the conversion factor:

1 kg = 2.205 lb

So, 183lb\times \frac{1kg}{2.205lb}=83kg

And, weight of Brandon measured at the health club = 85.0 kg

As, the weight at the health club is more than the previous measured weight. So, Brandon has gained weight.

  • <u>For b:</u>

We are given:

Amount of diced onions a recipe calls = 125 g

Mass of 1 onion = 4 oz

Converting the mass of 1 onion to ounces, we use the conversion factor:

1 oz = 28.35 g

So, 4oz\times \frac{28.35g}{1oz}=113.4g

To calculate the number of onions, we use the equation:

\text{Number of onions}=\frac{\text{Mass of onion a recipe calls}}{\text{Mass of 1 onion}}

\text{Number of onions}=\frac{125g}{113.4g}=1.1\approx 1

Hence, the number of onions required is 1.
