CH4+2O2–> CO2+2H2O
-count the number of atoms of each element on each side of the reaction arrow, there is 1 carbon,4 hydrogen, and 2 oxygen on the reactant side and 1 carbon, 2 hydrogen, and 3 oxygen on the product side.Then add coefficients so the number of atoms of each element is the same on both sides of the equation
Answer: check explanation
Explanation:
In this question we are to find mass. In order to calculate the Mass, We need the values of two parameters, that is, the values given for the grade tow chain, and the value given for the mass per length.
Assuming the mass per length is 3 Kilogram per metre(kg/m) and the grade 70 tow chain length is 5 metre(m).
Therefore, the formula for calculating mass of the chain is given below;
Mass of the chain= mass per unit length(kg/m) × length ---------------------------------------------------------------------------------------------------------------------(1).
Mass of the chain= 3 kg/m × 5 m.
Mass of the chain= 15 kg.
Mass to mass: moles A x(mole ratio of B/A) and mass to mole: extract the data from the question
Answer:
It is written exactly like that; Mg3N2
Explanation:
Roman numerals are used sometimes to show the charge of an ion that can be multiple charges.
