Answer:
C5H12 + 8O2 —> 5CO2 + 6H2O
The coefficients are 1, 8, 5,6
Explanation:
The equation for the reaction is given below:
C5H12 + O2 —> CO2 + H2O
Now let us balance the equation. This is illustrated below:
There are 5 atoms of C on the left side and 1atom on the right side. It can be balance by putting 5 in front of CO2 as illustrated below:
C5H12 + O2 —> 5CO2 + H2O
There are 12 atoms of H on the left side and 2atoms on the right. It can be balance by putting 6 in front of H2O as illustrated below:
C5H12 + O2 —> 5CO2 + 6H2O
There are a total of 16 atoms of O on the right side and 2atoms on the left side. It will be balance by putting 8 in front of O2 as illustrated below:
C5H12 + 8O2 —> 5CO2 + 6H2O
Now we see clearly that the equation is balanced as the number of atoms of the different elements on both sides of the equation are the same.
The coefficients are 1, 8, 5,6
Molar mass FeTiO3 => 151.7102 g/mol
atomic mass Ti => 47.867 u
% ( atomic mass Ti / molar mass FeTiO3 ) x 100
= ( 47.867 / 151.7102) x 100
= 0.3155 x 100
= 31.55 % of Ti
hope this helps!
Answer: Fe2O3
Explanation: By applying crisscross method, the formula will be Fe2O3.
Ans: 671.4 J
In nitric oxide,
Specific heat capacity (s) = 0.746 J/g°C
Mass (m) = 90 g
Initial temperature (t1) = -20°C
Final temperature (t2) = -10°C
Change in temperature (dt) = t2 - t1
= -10°C - (-20°C)
= -10°C + 20°C
= 10°C,,
.•. dt = 10°C
Amount of heat required (Q) =? (Joule)
Using heat equation,
Q= m*s*dt
= 90 * 0.746 * 10
= 671.4 J
Hence 671.4 Joules of heat is required.
The Formula for cm to mm is cm x 10 = mm so to replace it it would be, cm=9.78, so
9.78 x 10 = 97.8 mm hope this helped :) plz mark brainliest ʕ•ᴥ•ʔ
