Answer:
(True) The answer to that is yes, global warming is a hotly debated topic.
Explanation:
As a matter of political controversy, global warming is often viewed from different political perspectives. Which is why it is still an issue. (In 1988, global warming became a topic of discussion.) A number of climate change-related phenomena are occurring due to climate change, including rising temperatures, droughts and wildfires, changing precipitation patterns, glaciers melting, and rising sea levels.
Hope this helps! :D
Answer:
The amount present is 36g
Explanation:
Here, we are interested in calculating the amount of zinc in the bronze alloy since it is 18% of the total mass
What we do here is to calculate 18% of the total 200g
Mathematically, that would be 18/100 * 200 = 18 * 2 = 36g
<u>Answer:</u> The new volume of the gas will be 0.233L.
<u>Explanation:</u>
To calculate the new volume of the gas, we will use the equation given by Boyle's Law.
The above law states that the pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.
Mathematically,
(At constant temperature and number of moles)
or,
where,
are the initial pressure and volume of the gas.
are the final pressure and volume of the gas.
We are given:
Putting values in above equation, we get:
Hence, the new volume of the gas will be 0.233L.
<span>The preparation of 40 liters of 0.02 m phosphate buffer, ph 6.9, may be carried out by adding 132g of solid trisodium phosphate to 1290ml of hydrochloric acid (HCl concentration 1 mol/L), then making up to a final liquid volume of 40 liters by adding water.
Method: Weigh out 132 grams of Na3PO4 (s), and add it to 1290 ml 1M HCl (l). Mix, then add water, to a final volume of 40 liters.</span>
NACL, or salt, is an ionic compound made up of a cation from a base and an anion from an acid. (Water being the base.) Your answer would be the last option, "Formed due to reaction of acid with water."
