Its mainly about how much gunpowder is used in the shell. Thats all I got. XD
Assuming that the required amount of chlorine is added, we may calculate the mass of chlorine present in the product by first calculating the amount of product that will be formed from 15 grams of phosphorus.
Phosphorus has an atomic mass of 31, so 15/31 moles of phosphorus are added.
Next, we see that due to the equimolar ratio, the moles of product formed are also 15/31
The molecular mass of phosphorus trichloride is 137 g/mol. Therefore, the mass of product is:
137 * 15/31
= 66.3 grams
Now we know that 15 grams of phosphorus are present, so the remaining amount must be chlorine.
Chlorine = 66.3 - 15
Chlorine = 51.3 grams
Fusion in stars are usually the result of gravity. Once a mass of hydrogen accumulates enough mass, the gravity of all that mass compresses the core of the star to the point that the hydrogen atoms there begin fusing into helium. The <span>process then cascades outward, and the end result is a star. Hopes ths Helps. Also mark me brainliest since I was first

6. fuel is needed in space to power certain things like engines.
7. It couldn't, as the lowest speed acceptable to get into space is 7.9 km per second (28,440 km per hour). This is because to break into the barrier that no longer contains oxygen, you would need to be going at an extremely fast rate.
8. It involves Newton's 3rd law. The movement requires that same thrust to be thrown back, also.
9. There is no gravity. So, basically, you just float.
Answer:
Explanation:
The sun keeps all of the planets in orbit around it. Without the sun, all of the planets would fly off into space (out of orbit)
