Probably telophase because for the difference in the nuclear membrane
16 grams.
Looking at the reaction equation, it's evident that for each mole of HBr
consumed, 1 mole of CO2 will be produced. So let's calculate the molar mass
of HBr and CO2 first.
Atomic weight hydrogen = 1.00794
Atomic weight bromine = 79.904
Atomic weight carbon = 12.0107
Atomic weight oxygen = 15.999
Molar mass HBr = 1.00794 + 79.904 = 80.91194 g/mol
Molar mass CO2 = 12.0107 + 2*15.999 = 44.0087 g/mol
Moles HBr = 30 g / 80.91194 g/mol = 0.370773461 mol
Grams CO2 = 0.370773461 mol * 44.0087 g/mol = 16.317258 g
Rounding to 2 significant digits gives 16 grams.
Answer:
Metal name (charge in roman numerals) Non metal
for example Iron (III) chloride
Explanation:
The rule for naming special transition metal are as follows -
a) First name the transition metal
b) Now write the name of the non metal in the chemical formula.
c) Write the charge for the non metal.
d) If there is a polyatomic ion, write the Common Ion Table ,its formula and charge.
e) Based on the total charge on the non-metal or polyatomic ion, deduce the total charge on the transition metal
f) Write the charge of transition metal after the name of metal in Roman Numeral in parentheses
21. change in temperature, change in color, or noticeable odor (after reaction has begun)
22. Picture... Wasn't so sure about this since no charge was given, so I suspected it has a charge of 2. If you have more information on this I would be glad to help, and I can't tell what is happening with the calculations given. It would be helpful if you can add spaces or put a line break.
23. An ion is an atom or molecule with an electric charge. It is formed when atoms lose or gain electrons. There are two types of ions: cations (net positive charge) and anion (net negative charge).
24. Picture
25. a) dinitrogen tetrahydride
b) phosphorus triiodide
c) lithium hydroxide
All you have to do is a simple division "parts over the whole"
12.3 grams H/ 110 grams compound x 100= 11.2%
