Answer:
The answer is most likely A. Definite proportions
Explanation:
The Law of Definite proportions states that a given chemical compound always contains its component elements in fixed ratio (by mass) and does not depend on its source and method of preparation.
Answer:
I was traveling on a train where I fell asleep. someone stole my luggage in which I had money and other essentials. when the ticket checker arrived a lady paid my fine. she helped me a lot. when I told her about being robbed she helped me and took me to the police station and I found my bag.

Hi. 2fouls! :)
First convert the number from kilometer to miles:
Now to find the miles per minutes,divide the miles per hours by 60 (the amount of minutes in an hour.)
The car is travelling at a speed of 0.860766667 miles/minute.
Hope this helps.

Answer;
-More carbon dioxide causes an increase in carbonic acid (H2CO3) which leads to a decrease in the concentration of carbonate ion (CO32-).
Explanation;
-Carbon dioxide is added to the atmosphere whenever people burn fossil fuels. Oceans play an important role in keeping the Earth's carbon cycle in balance.
-As the amount of carbon dioxide in the atmosphere increases, the oceans absorb a lot of it. In the ocean, carbon dioxide reacts with seawater to form carbonic acid which causes the acidity of seawater to increase.
-As long as we keep putting extra carbon dioxide in the atmosphere, the acidity of the ocean will continue to increase. The effect is that; Increasing acidity makes it harder for corals to build skeletons and for shellfish to build the shells they need for protection. Corals are particularly important because they provide homes for many other sea creatures.
V1 = 30 mL
P1 = 760 torr
P2 = 1520 torr
V2 = ?
applying Boyle's Law
P1*V1 = P2*V2
760 torr * 30 mL = 1520 torr * V2
V2 = 760 torr * 30 mL / 1520 torr
( C ) is correct
