Answer:
874.59
Explanation:
The number after 9 is 1
1 is lower than 5 so we leave the previous number the same
V1/T1 = V2 / T2
V1 = 3/4(1700) = 1275
T1 = 10 + 273.15 = 283.15
V2 = 1700
T2 = V2T1
T2 = (1700) (283.15) / 1275
T2 = 377.53 K
Chemical reactions convert reactants to products, whose properties differ
from those of the reactants. Chemical equations are a compact and
convenient way to represent chemical reactions. They have the general form
Reactant(s) → Product(s)
The arrow in the equation means "changes to" or
"forms." The reaction of gaseous nitrogen with hydrogen to
produce ammonia, NH

, is represented by the chemical equation
Although there are thousands of chemical reactions, a significant number
of them, especially those that are not organic reactions, can be
classified according to four general patterns: combination, decomposition,
displacement, and exchange.

Answer:
Au
Explanation:
For the density of a face-centered cubic:
where
= molar mass of the compound
avogadro's constant
the volume of a unit cell
Given that:
Density 
= 19.30 g/cm³
a = 0.408 nm
a = 
a = 
∴
Thus, the molar mass of 197.37 g/mol element is Gold (Au).
