Answer:
2266g
Explanation:
mass = no.of molecules /6.o23*1o(23) * molar mass
molar mass of co2= 44g /mol
1.5 .10^25/6.023 .10^23 =51.5 moles of co2
51.5 .44g/mol =2266 g
ANSWERS:
Group 2 metal carbonates, nitrates and hydroxides decompose to heat to give the corresponding metal oxide and release CO2, NO2 and O2, and H2O respectively. The thermal stability increases down the group as theionic character of the compounds increases down the group.
Answer: <u>A integer is a whole number.</u>
<em>An adult with the flu has a temperature of 102°F</em>
<em>A brain contains neurons (moving the decimal point to the right side power of 10 increases........here decimal point is moved to two places to the right side so power of 10 decreases from 10 to 8)</em>
<em>The time for a nerve impulse to travel from the feet to the brain is s. (moving the decimal point to the right side power of 10 increases........here decimal point is moved to two places to the right side so power of 10 decreases from 0 to -2)</em>
Explanation:
i hope this answer your question if this is wrong or correct please let me know
So basically, the change in color effects the amount of cations in the solution making it a physical change rather than a chemical one, defying the law of conservation of mass! I hope this helped! (The only time the change in color affects the amount of cations is in the Alkaline Earth Metals)

Explanation:
Moles=mass/molar mass
moles × molar mass = mass
0.206 x 119= mass
Mass= 24. 51grams
