The question is incomplete , the complete question is;
The mass of each Wt isotope is measured relative to C-12 and tabulated below. Use the mass of C-12 to convert each of the masses to amu and calculate the atomic mass of Wt.
Wt-296 = 24.6622
Answer:
The atomic mass of Wt-296 is 195.9464 amu.
Explanation:
1 amu is defined as 1 by twelfth of the carbon-12 mass.
Mass of an isotope Wt-296 = 24.6622
Mass of an isotope Wt-296 in amu = M
The atomic mass of Wt-296 is 195.9464 amu.
The quality of being toxic or poisonous
2 C4H10 + 13 O2 → 8 CO2 + 10H2O
Given, Heat of formation of C4H10 = = -125.7 kJ/molHeat of formation of water = = -241.82 kJ/molHeat of formation of CO2 = = -393.5 kJ/mol
Thus, enthalpy of combustion = ΔH = ∑Hproducts - ∑Hreactants = 8 + 10 - 2 = (-393.5X8) + (-241.82X10) - (-125.7X2) = -5314.8 kJ/mol
This energy would result in combustion of 2 moles of butane∴ For 1 mole, energy required for combustion of butane = -5314.8/2 = -2657.4 kJ/mol
Answer:
any of the set of metallic elements occupying a central block (Groups IVB–VIII, IB, and IIB, or 4–12) in the periodic table, e.g., iron, manganese, chromium, and copper. Chemically they show variable valence and a strong tendency to form coordination compounds, and many of their compounds are colored.
Explanation:
Carbon has 4 electrons in its outermost shell.it shows tetravalency and catination property hence forms long chain of carbon .
