The balanced chemical equation for the formation ammonia is
N2(g) + 3H2(g) ----> 2NH3(g) .
The balanced chemical equations explains that the same number of each element exist as reactants and products. The coefficients in a balanced equation must be the simplest whole number ratio. Mass is always conserved in chemical reactions.
For the formation of ammonia, the chemical equation is
N2(g) + H2(g) ----> NH3(g)
Balancing the chemical reaction, we can write,
N2(g) + 3H2(g) ----> 2NH3(g) .
This equation shows two nitrogen entering the reaction together and two hydrogens entering the reaction together. Since NH3 is multiplied by a coefficient of 2 there are now 2 nitrogen and 6 hydrogens. The 6 hydrogens come from the 2 multiplied by the subscript of 3. This is the balanced chemical reaction.

The Answer is A CH2O
The molecular formula for glucose is C6H12O6. The subscripts represent a multiple of an empirical formula. To determine the empirical formula, divide the subscripts by the GCF of 6 which gives CH2O.
When methane gas, CH4, burns completely in oxygen, the reaction produces carbon dioxide and water, as seen in the equation. CH4+2 O2 CO2 + 2 H20.
Answer:
The unknown substance is rhodium.
Explanation:
Heat lost by hot substance will be equal to heat gained by the water
Mass of substance= 
Specific heat capacity of substance= 
Initial temperature of the substance = 
Final temperature of substance= 
Mass of water = M
Volume of water ,V= 35 ml
Density of water = d = 1.00 g/mL
Mass of water= 
Specific heat capacity of water= 
Initial temperature of the water = 
Final temperature of water = 
On substituting all values:
we get, 
The value of heat capacity of the substance is equal to that of rhodium metal.Hence, the unknown substance is rhodium.
