Answer:
202.76 inches
Explanation:
1 meter = 39.37 inches
5.15 × 39.37 = 202.7559,when rounded it's 202.76
A physical process is a process which do not change the substance structure only its shape or phase is changed. On the other hand, a chemical process involves the formation of new substances.
a. corrosion of aluminum metal = chemical process
b. Melting of ice = physical process
c. Pulverizing an aspirin. = physical processd. Digesting a candy bar. = chemical process
e. Explosion of nitroglycerin. = chemical process
f. Milk turning sour. = chemical process
g. Burning of paper. = chemical process
h. Forming of frost on a cold night. = physical process
i. Bleaching of hair with hydrogen peroxide. = chemical process
j. A copper wire is hammered flat. <span>= physical process</span>
Heterogeneous, which means that they are not evenly combined.
Answer:
4.1M = [CH₃OH]
Explanation:
The equilibrium produced for the reaction between CO and H₂ to form CH₃OH is:
CO + 2 H₂ ⇄ CH₃OH
Where Keq is defined as:
Keq = 26 = [CH₃OH] / [CO] [H₂]²
<em>For concentrations in equilibrium</em>
Replacing in Keq the equilibrium concentrations of CO and H₂, the equilibrium concentration of CH₃COOH is:
26 = [CH₃OH] / [3.4x10⁻¹M] [6.8x10⁻¹M]²
<em>4.1M = [CH₃OH]</em>
The answers are name: Cerium, symbol: Ce, atomic number: 58, and atomic mass: 140.110
