Need help with some chem equations 1. While diving under 3.7 atm of pressure, a gas bubble of 25 mL was found when release at surface at 1 at how big did the bubble get

2. a blue 3 L balloon at 25c was moved to a temperature of 38c what is new volume

3. 1.72 L of gas at STP was transferred to a new container with temps 18c and volume of 3.1 L what is new pressure

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8  

mgco3-5h2o"

the increase of protons   hope this

personal, she chose to do it.

you need to stop taking that class
