Sodium reacts with chlorine gas to form sodium chloride. what mass of sodium chloride is produced if 92.0 g sodium reacts with excess chlorine?

234 g

Explanation:

We know we will need a balanced equation with masses and molar masses, so let’s gather all the information in one place.

M_r:      22.99                58.44

              2Na  +  Cl₂ ⟶ 2NaCl

Mass/g: 92.0

1. Calculate the moles of Na

Moles Na = 92.0 × 1/22.99

Moles Na = 4.002 mol Na

2. Calculate the moles of NaCl

The molar ratio is 2 mol NaCl:2 mol Na.

Moles of NaCl = 4.002 × 2/2

Moles of NaCl = 4.002 mol NaCl

3. Calculate the mass of NaCl

Mass of NaCl = 4.002 × 58.44

Mass of NaCl = 234 g

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

i think? ?

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
