Answer:
–0.13 Pa.m²
Explanation:
From the question given above, the following data were obtained:
Measurement (Pa.mm²) = –1.3×10⁵ Pa.mm²
Measurement (Pa.m²) =?
We can convert from Pa.mm² to Pa.m² by doing the following:
1 Pa.mm² = 1×10¯⁶ Pa.m²
Therefore,
–1.3×10⁵ Pa.mm² = –1.3×10⁵ Pa.mm² × 1×10¯⁶ Pa.m² / 1 Pa.mm²
–1.3×10⁵ Pa.mm² = –0.13 Pa.m²
Thus, –1.3×10⁵ Pa.mm² is equivalent to –0.13 Pa.m².
During a combustion reaction the carbon in a hydrocarbon compound is paired with Oxygen (O2) in the air to form Carbon-Dioxide (CO2), whilst the Hydrogen too pairs with Oxygen to form water vapour (H2O). Heat is also produced during this reaction.
The correct answer is 1) Ag, Si, I₂
Ag or silver is a metal. Silver is a transition element which lies in the d-block of the periodic table.
Si or silicon is a metalloid. Silicon is a metalloid which lies in the p-block of the periodic table.
I₂ or iodine is a nonmetal. Iodine is a halogen which lies in group 17 of the periodic table. All halogens are nonmetals.
Answer:
The water molecule is comprised of two hydrogen (H) atoms and one oxygen atom, oxygen atom has 8 electrons, and each H has 1 electron. The H atoms bond to the oxygen by sharing a pair of electrons in what is called a covalent bond. In each pair of shared electrons, one electron is contributed by the H (black) and one from the oxygen (red).
