A compound has a molar mass of 44.01 g/mol. What is its identity?
Bess [88]

This problem is very vague since no other details are given. However for the sake of calculation let us assume that the compound is an ideal gas at STP.

So that the molar volume is: 1 mole = 22.4 L

 

<span>density = (44.01 g/mol) * (1 mol / 22.4 L) = 1.96 g/L = 1.96 kg/m^3</span>

Refer to the balanced equation. (PLEASE HELP QUICK)
kolezko [41]

Answer: C) 5.12\times 10^1 L Cl_2

Explanation: 8H_2S+8Cl_2\rightarrow S_8+16HCl

According to Avogadro's law, 1 mole of every gas occupies 22.4 Liters at STP.

Thus from the balanced chemical equation, 8 moles of hydrogen sulfide reacts with 8 moles of chlorine gas.

i.e 8 moles of hydrogen sulfide reacts with =8\times 22.4L=179.2L of chlorine gas.

2.28  moles of hydrogen sulfide reacts with =\frac{179.2}{8}\times 2.28=51.2L=5.12\times 10^1L of chlorine gas.

Someone pleaseeee help me I need it now​
denis23 [38]

Answer:

Personal Question

Explanation:

I wish I could help more, but it's based on your own prior knowledge, desires and experiences. Only you can answer those questions. For the first one, if you know examples of genetic engineering you could write that, or you could define it. For the second one, you could talk about things that interest you. The last one you could talk about the concepts you learned in the lesson and the things you didn't know before the lesson and then learned afterward. You could talk about the methods of genetic manipulation, or just what you learn in the class.
