Answer:
Density of Ar gas under the given condition is 1.52 g/L
Explanation:
Density in grams/liter = (mass of Ar gas present in flask)/(volume of flask)
We know, number of moles = (mass)/(molar mass)
Molar mass of Ar = 39.948 g/mol
So, mass of 0.228 mol of Ar =
Volume of flask = 6.00 L
So, density of gas inside flask =
Hence, density of Ar gas under the given condition is 1.52 g/L
D - Silicon
This is because Silicon has four electrons as indicated by the group it's in. Chlorine would have 7, Magnesium would have 2, Phosphorous would have 5, and Sulfur would have 6.
Hope this helps!
Answer:
Although scientists have been working hard to find a cure to this deadly disease, yet a sudden new like this will not be considered at first to be true. In order to make the public believe in this report, there should be authentic results from the trial experiments showing at least 90% of patient recovery. Also, there should be enough investigation done on the side effects of this medicine and the ingredients used in its making.
2.3 dL = .23 liters. d=deci=10^-1 so you move the decimal place back once.
It's D because micro is 10^-6 (move the decimal place back 6 times) 230,000x10^-6=.23 liters or 2.3 dL.
Answer:
Some bacteria like <em><u>rhizobium</u></em> and <u><em>blue green algae</em></u> are able to fix nitrogen gas from the atmosphere to enrich the soil with nitrogen compounds and increase its fertility. The nitrogen-fixing bacteria and blue green algae are called <u><em>biological nitrogen fixers.</em></u>
