Idk it’s making me answer a question in order to get help on my own
Answer:
A
Explanation:
The Charles law states that the volume of an ideal gas increases when temperature is increased under constant pressure. The pressure inside the balloon is always equal to the atmospheric pressure. Therefore answer A demonstrate the Charles law.
<span>1.18 x 3 = 3.55 </span>
find ratio of F to F in each compound
. according to law of multiple proportions that the masses of one element which combine with a fixed mass of the second element are in a ratio of whole numbers.
now F is "one element" and S has "fixed mass",
the ratio of F6 to Fx = 3:1
<span>thats why x= 2
there is less F in SFx
the ratio is 3:1.
dividing 6 by 3 and you get 2</span>
Because a good stepping stone would be a solid and if that solid were to melt or turn to gas you’d have no stepping stone.
<h2>Steps:</h2>
- Remember that Density = mass/volume, or D = m/v
So firstly, we have to find the volume of the rock. To do this, we need to subtract the volume of water A from the volume of the water B. In this case:
- Water A = 30 mL
- Water B = 40 mL
- 40 mL - 30 mL = 10 mL
<u>The volume of the rock is 10 mL.</u>
Now that we have the volume, we can plug that and the density of the rock into the density equation to solve for the mass.
For this, multiply both sides by 10:
<h2>Answer:</h2>
<u>Rounding to the tenths place, the mass of the rock is 36.8 g, or C.</u>
