The equations are not balanced. which equation would have the same coefficients in the same order as 2co2 + 3h20 → c2h6o + 3o2?

a: al + feo → al2o3 + fe
b: ch4 + o2 →co2 + h2o
c: pcl5 + h2o → hcl + h3po4
d: fecl3 + nh4oh → fe(oh)3 + nh4cl

 A.

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

A.

B.

C.

D.

Thus the coefficients of 2, 3, 1 and 3 as present in  will be same in  .

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.
