To calculate your answer: 
list atoms
multiply by subcript outside parentheses
multiply by coefficient

<span>3 H2SO4 + 2Al → Al2(SO4)3 + 3H2

H  2  x3 =6                  H 2 x 3 = 6
S  1 x 3 = 3                 S 1x 3 = 3
O  4  x3 = 12              O 4 x 3 = 12
Al  1  x 2 = 2               Al 2


This one is balanced . . . now you try the other one.  Let me know if you still need help</span>

The answer would be option B "I believe there is life on other planets." Scientific statements have a possibility to be wrong. It's not option A because option A is a opinion. It's not option C because option C is a fact. It's not option D because option D is a opinion.

Hope this helps!

2. What pressure is required to compress 196.0 L of air at 1.00 atmosphere into a cylinder
damaskus [11]

Answer:

<h2>7.54 atm </h2>

Explanation:

The required pressure can be found by using the formula for Boyle's law which is

P_2 =  \frac{P_1V_1}{V_2}  \\

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

From the question we have

P_2 =  \frac{1 \times 196}{26}  =  \frac{196}{26}   \\ = 7.538461...

We have the final answer as

<h3>7.54 atm </h3>

Hope this helps you
