Write a complete, balanced equation for the following reactions: e) The heating of sodium carbonate (teachers note: produces sodium oxide and carbon dioxide).
f) chromium (III) hydroxide plus sulfuric acid (teachers note: You figure out products).
g) aluminum metal plus chlorine gas (teachers note: produces aluminum chloride).

Please explain as well, thanks!

Solution given:

e) The heating of sodium carbonate to produces sodium oxide and carbon dioxide

Solution given:

Balanced chemical equation:

when sodium carbonate is heated it decomposed and form sodium oxide and carbon dioxide

f) chromium (III) hydroxide plus sulfuric acid

Balanced chemical equation:

When chromium (III) hydroxide react with sulfuric acid double displacement takes place and forms produce chromium(III) sulfate and water.

g) aluminum metal plus chlorine gas

When aluminum metal is added to chlorine gas Combination reaction takes place and forms aluminum chloride.

e) The heating of sodium carbonate to produces sodium oxide and carbon dioxide

Solution given:

Balanced chemical equation:

when sodium carbonate is heated it decomposed and form sodium oxide and carbon dioxide

f) chromium (III) hydroxide plus sulfuric acid

Balanced chemical equation:

When chromium (III) hydroxide react with sulfuric acid double displacement takes place and forms produce chromium(III) sulfate and water.

g) aluminum metal plus chlorine gas

When aluminum metal is added to chlorine gas Combination reaction takes place and forms aluminum chloride.

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).

what is the question here. i think you messed up.
