Answer:

1) Se2O5

2) I2O6

3)Zn3n2

4) Cr(HCO3)3

Explanation:

selenium pentaoxide (= also called diselenium pentoxide)

= Se2O5

⇒ Se = 78.97 g/mol

⇒ O = 16 g/mol

⇒ 2*78.97 + 5*16 = 237.94 g/mol

iodine trichloride

= I2O6

⇒ I = 126.9 g/mol

⇒ Cl = 35.45 g/mol

⇒ 2* 126.9 + 6 * 35.45 = 466.5 g/mol

zinc (1) nitride does not exist  (it's Zinc(ii)nitride

The oxidation number for zinc is always 2

Zn3n2

⇒ Zn = 65.38 g/mol

⇒ N = 14 g/mol

⇒3*65.38 + 2* 14 = 224.14 g/mol

chromium (III) bicarbonate

Cr(HCO3)3

⇒ Cr = 52 g/mol

⇒ H = 1.01 g/mol

⇒ C = 12 g/mol

⇒ O = 16 g/mol

52 + 3*1.01 + 3*12 + 6*16 = 235.03 g/mol

Carbon disulfide is formed by the reaction of coke (carbon) with sulfur dioxide. how many moles of cs2 will be generated if 8.0
trapecia [35]
<span>The equation that produces carbon disulfide from the reaction of coke and sufur dioxide is expressed in the balanced equation: c+ 2sO2 = CS2 + 2O2. For every mole of coke reacted, there is one mole of carbon disulfide produced. Hence the answer here is 8 moles of CS2 </span>

How is the information about cats found in myths and fairy tales and legends different from information gathered through science
forsale [732]
Scirnce uses a method of testing to declare rules or facts. myth and fairy tales have no way of being tested. cats are a physical creature we can see, test, and observe. a mythical idea canny be tested. for example: mermaids cannot be tested as we have none to observe.
