A resting heart rate is usually around 40 beats per minute (Thats the normal amount)
all i know is that the formula for triangles is base times hight divided by two, so add in a number to replace the missing number, multiply it by 55 and divide the answer by two. hope this helps and i really hope you get it right! or that im right...
Water is a pure substance, however it is made up of oxygen and hydrogen atoms, hence the nickname H2O (Hydrogen2, Oxygen)
B) Exothermic
The reaction released heat energy to its surrounding, thus, it was exothermic.
"exo" is to expel or put outside
"thermic" means heat
Answer: 12L
Explanation:
To find the correct volume of the balloon, we can use the mathematical representation of Boyle’s law which states that a gas’s volume is inversely proportional to its pressure (as one increases the other decreases).
The equation for it is P1 * V1 = P2 * V2 where P1 and V1 represent the initial pressure and volume of the gas and P2 and V2 represent its changed temperature and volume.
In this case, the initial pressure of the gas inside the balloon is 3atm while its initial volume is 2.0L. Its pressure is then reduced to 0.5atm.
If we apply this information to the equation for Boyle’s law, we get
2L * 3atm = 0.5atm * V2.
Through arithmetic, we find that
6 = 0.5atm * V2
6/0.5atm = V2
12L = V2.
So, the volume of the balloon is 12L.
Hope this helps!
