Is 2Na+Cl2=2NaCl a balanced chemical equation

Chemistry
1 answer:
lilavasa [31]3 years ago
3 0

Hey there!

2Na + Cl₂ → 2NaCl

This is a balanced chemical equation.

There are 2 atoms of sodium (Na) on the left, and 2 atoms of sodium (Na) on the right.

There are 2 atoms of chlorine (Cl) on the left, and 2 atoms of chlorine (Cl) on the right.

This means the equation is balanced since there are the same amount of each element on both sides.

Hope this helps!

Why is the third equivalence point not observed in the titration curve for phosphoric acid?
BigorU [14]
<span>The third equivalence point is not observed in the titration curve of phosphoric acid because the specific point is concealed due to the rapid ionization of water which in turn forms an hydroxide ion and a molecule called hydronium molecule. The pH value changes more at the first and second points.</span>

In step 2 of the experimental procedure, you added 6 M sodium hydroxide to the copper(II) nitrate solut form copper(II) hydroxid
kicyunya [14]

Answer:

The solution becomes colorless and a light blue precipitate is formed.

Explanation:

When sodium hydroxide is added to copper(II) nitrate solution, a precipitate of  copper(II) hydroxide is formed.

The solution gradually becomes colorless as the light blue precipitate appears.

The reaction is complete (enough sodium hydroxide has been added) when the blue color of the solution completely disappears.

The equation of the reaction is;

Cu(NO3)2(aq) + 2NaOH(aq) → Cu(OH)2(s) + 2NaNO3(aq)

if you had to explain to someone the difference between heat and temperature, how could you use one of the following to demonstr
Rainbow [258]

Answer:

We associate paper money or points in video games, as molecules that make a heat transfer or an increasin in its temperature.

Explanation:

The meaning of heat is associated with an energy transfer, where for example if we put a spoon in a cup of hot drink, the drink will be transferring heat to the spoon. It is a transfer of energy between two bodies due to a difference between their temperatures.

Temperature is associated with the movement of kinetic energy of the molecules. When the temperature is higher, the kinetic energy is higher, so as more detained they are, temperature will be lower.

If we take paper money as molecules, the greater movement of money explains that we have an increase in temperature (we would be hot), even if we think of video games, for example gambling where as more points we gain, we generate an increase in the movement of "molecules".

When we use paper money to buy something we are doing a heat transfer.

We can associate terms to the Thermodynamic where

Heat = Internal energy + work

For clearance would be

Internal energy = Heat - Work

The money we use less the work we do keeps our internal energy. If in a gambling video game, we earn points over and over again, when withdrawing the prize we perform "heat transfer".

What is the concentration of chloride ion when 16.8ml of a 0.554 M solution of barium chloride is combined with 16.8ml of a 0.59
ozzi

Answer:

The concentration of chloride ion is 2.887 M.

Explanation:

Here we have a combination BaCl₂  and AlCl₃

1 mole BaCl₂ can produce 2 moles chloride ions as follows;

BaCl₂ → Ba²⁺ + 2Cl⁻

Therefore;

0.554  mole BaCl₂ can produce 2×0.554  moles chloride ions;

1 mole AlCl₃ can produce 3 moles chloride ions as follows;

AlCl₃ → Al³⁺ + 3Cl⁻

Therefore;

0.593 mole AlCl₃ can produce 3×0.593 moles chloride ions

Total concentration of chloride ions = 2×0.554 + 3×0.593 = 2.887 moles of Cl⁻ in 2×16.8 ml solution

The concentration of Cl⁻ is 2.887 M
