B) A piece of solid gold was heated from 274K to 314K using 55.7J of energy to raise the

Chemistry
1 answer:
Solnce55 [7]3 years ago
8 0

Answer:

Explanation:

So we know q = mc\DeltaT.

q = 55.7 J

c = 0.129j/g°C

and \DeltaT = 314-274 = 40°C.

and m is mass which can solve since we got every other variable. We will get m = 10.8g.

What is the density at STP of the gas sulfur hexafluoride, SF6?
svetoff [14.1K]

Answer:

Explanation:

There is a formula for this:

M = DRT/P where M = molar mass. This just derived from PV = nRT where you say n = grams/molar mass. However, just with this formula, we can get D which is density at STP (1 atm and 273K). We find that D = 6.52g/L.

The shape of the organism is a huge factor, as it could fact for a different creature and/or organism every time. For example, a antelope may have a different form or structure of let’s say a spider, as this is the significant factor of ones shape, the first observation.

Secondly, the colors. As different organism come in different areas of reflections of light, it can easily be identified with this certain color and the way that the light reflects on it. This is another form of visual appearance, and important factor in identification.

Lastly, the pattern. As located on the back, the spikes/thread-looking things sticking out plays a huge factor in finding the organism name and/or identifying it. Every organism has a different pattern, humans being a huge one, all different

Observational studies of organisms is significant to our lives, and it’s greatly helped progress our sciences and society.

Predict the products of each reaction, and whether the solution at equilibrium will be acidic, basic, or neutral.1. P4O10 + 6H2O
77julia77 [94]

<u>Answer:</u>

<u>For 1:</u> The product is phosphoric acid and the solution is acidic in nature.

<u>For 2:</u> The product is sodium hydroxide and the solution is basic in nature.

<u>For 3:</u> The product is nitric acid and the solution is acidic in nature.

<u>Explanation:</u>

For the given options:

(1): When diphosphorus pentoxide reacts with water, it leads to the formation of phosphoric acid, which makes the solution acidic in nature.

The chemical equation for the reaction follows:

P_4O_{10}+6H_2O(l)\rightarrow 4H_3PO_4(aq)

(2): When disodium oxide reacts with water, it leads to the formation of sodium hydroxide, which makes the solution basic in nature.

The chemical equation for the reaction follows:

Na_2O+H_2O(l)\rightarrow 2NaOH(aq)

(3): When dinitrogen pentoxide reacts with water, it leads to the formation of nitric acid, which makes the solution acidic in nature.

The chemical equation for the reaction follows:

3N_2O_5+3H_2O(l)\rightarrow 6HNO_3(aq)
