Describing Chemical Reactions
nadya68 [22]

Answer:

mass of Liquid 1 + mass of Liquid 2 = mass of solid + mass of gas

Explanation:

iquid 1 reacts with Liquid 2, producing a solid and a gas. Using this scenario, which supports the law of conservation

of mass?

EEEE

O mass of Liquid 1 + mass of solid = mass of Liquid 2 + mass of gas

O mass of Liquid 1 - mass of solid = mass of Liquid 2-mass of gas

O mass of Liquid 1 - mass of Liquid 2 = mass of solid + mass of gas

O

based on the law of the conservation of matter, the sum of the masses of the reactants must equal  the sum of the masses of the products

so the correct answer is

mass of Liquid 1 + mass of Liquid 2 = mass of solid + mass of gas

Need some help with this problem please!
Tom [10]

Answer:

18 liters

Explanation:

Step 1: Figure out what the formula and what you are dealing with.

- 25 degrees celcius is constant, so it is irrelevant for the mathmatical part.

- P1 = 1 atm

- P2 = 20 atm

- V1 = 360 liters

- V2 = trying to find

Note: remember the original equation is V1/P1 = V2/P2

- Step 2: Rearrange the equation to fit this problem, you should get...

V2 = V1 x P1 / P2

- Step 3: Fill our own numbers in. You should get...

360 L x 1 atm / 20 atm = 18 Liters (do the math)

- Answer = 18 Liters

- Remember to just follow the formula and fill it in with your own numbers.

If you need any more help comment below. I am happy to help anytime.
