Your answer is A my friend as the atomic number of an atom is determined by the number of protons
Answer:
Electrical conductivity is the ability of matter to conduct, or carry along, an electric current. Copper often is used for electrical wiring because it has high electrical conductivity
Explanation:
Explanation:
Selenium and tellurium are rare elements, respectively, in order of crustal abundance. However, polonium, on account of its radioactive decay, is less abundant. The main source of selenium and tellurium is the anode slime deposited during the electrolytic refining of copper.
Answer: 0.0195g of CO2 is produced
Explanation:
CH4 + 2O2 —> CO2 + 2H2O
Molar Mass of CO2 = 12 + (16x2) = 12 + 32 = 44g/mol
Molar Mass of CH4 = 12 + (4x1) = 12 + 4 = 16g/mol
From the equation,
16g of CH4 produce 44g of CO2.
Therefore 7.10×10^−3 of CH4 will produce Xg of CO2 i.e
Xg of CO2 = (7.10×10^−3x44) /16 = 0.0195g
