How many grams of sodium are needed to react completely with 19

Chemistry
1 answer:
gtnhenbr [62]3 years ago
6 0

Answer:

46 g of sodium

Explanation:

Sodium reacts vigorously with fluoride gas to form NaF as shown

2Na (s) + F2 (g) ------> 2NaF (s)            (Na = 23, F = 19)

2 moles of Na reacts with 1 mole of F2 to produce NaF

By calculating the molar mass of the elements involved in the reaction then multiplied by the mole, the mass can be obtained.

23 * 2 g/mol of Na reacts with 1 * 19 g/mol of F2

46 g/mol of Na reacts with 19 g/mol of F2 to produce NaF

Since the mole ratio is 2 to 1 and 19 g of F2 is used for the reaction, 46 g of sodium will be consumed for the reaction to be achieved.

Is It Deadly To Mix Bleach, Rubbing Alcohol, And/or Hydrogen Peroxide?
Oduvanchick [21]
Mixing bleach with rubbing alcohol and/or hydrogen peroxide can run the risk of producing chlorine gas. This is a gas that if inhaled in excess, or at all, is extremely dangerous, harmful or even fatal. Keeping this in mind, it is therefore not recommended that you mix these substances together. The label of your rubbing alcohol will recommend any substances it can or cannot be mixed with.

You might have a flashlight that runs (2) d-cells of 1.5 volts each in series. the bulb is rated for 0.7 amps. what’s its resist
sweet [91]
From Ohm's law, we get the general equation that would relate the voltage, current, and resistance,
                                  V = I x R
where V is voltage, R is resistance, and I is current. Deriving the equation for R
                                       R = V / I
                              R = (1.5 volts) / (0.7 amps) = 2.14 Ohms

Which property of table salt is also a property of other ionic compounds
Svet_ta [14]
Most likely it’s crystalline structure, which makes it small granules that are soluble in water. Most, if not all, ionic compounds are salts. And salts dissolve in water.

Hope that’s correct
