Answer:
CH2O
Explanation:
Dividing by the atomic masses:
40 / 12 = 3.333
6.7 / 1 = 6.7
53.3 / 16 = 3.331
The ratios are
3.333/ 3.333 : 6.7 / 3.333 : 3.331/3.333
= 1:2:1.
So it is CH2O.
Answer:
Convection
Explanation:
Convection is a mode of heat transfer that involves the actual movement of particles. In this case the particles are air particles.
Since hot air is less dense, it is pushed up by the denser cool air. This process may continue indefinitely and a convection current is set up.
Answer:
134K
Explanation:
Using the ideal gas law equation;
PV = nRT
Where;
P = pressure (atm)
V = volume (Litres)
n = number of moles (mol)
R = gas constant (0.0821 Latm/Kmol)
T = temperature (K)
Based on the information provided, n = 1.4moles, P = 3.25atm, V = 4.738L, T = ?
3.25 × 4.738 = 1.4 × 0.0821 × T
15.3985 = 0.11494T
T = 15.3985/0.11494
T = 133.969
Approximately;
T = 134K
I think ionic ?
i dont know so dont take my anwser yet
