What is the formula for Na+1 and SO3^-2

Chemistry
1 answer:
KATRIN_1 [288]3 years ago
8 0

Answer:

Na₂SO₃

Explanation:

We can use the <em>criss-cross method</em> to work out the formula.

1. Write the <em>symbols</em> of the anion and cation.

Na¹⁺  SO₃²⁻

2. <em>Criss-cross the numbers of the charge</em>s to become the subscripts of the other ion (see image).

3. Write the formula with the <em>new subscripts</em>.

Na₂(SO₃)₁

4. Omit all subscripts <em>that are 1.</em>

The formula becomes Na₂SO₃.

ILL MARK BRAINLIEST :)
DanielleElmas [232]

Explanation:

According to the law of conservation of mass, mass can neither be created nor destroyed but it can simply be transformed from one form to another.

For example, Na^{+} + Cl^{-} \rightarrow NaCl

Mass of Na = 23 g/mol

Mass of Cl = 35.5 g/mol

Sum of mass of reactants = mass of Na + mass of Cl

= 23 + 35.5 g/mol

= 58.5 g/mol

Mass of product formed is as follows.

Mass of NaCl = mass of Na + mass of Cl

= (23 g/mol + 35.5) g/mol

= 58.5 g/mol

As mass reacted is equal to the amount of mass formed. This shows that mass is conserved.

As a result, law of conservation of mass is obeyed.

What can you conclude from the fact that electrons orbit far away from atomic nuclei?
suter [353]
Electrons are extremely small. Atoms are comprised mostly of empty space. Protons have a positive charge.
Hope this helps.

The temperature of 15.71 grams of gold rises from 32°C to 1,064°C, and then the gold melts completely. If gold’s specific heat i
antoniya [11.8K]

Answer:Total energy gained by 15.71 g is 3090.6471 joules

Explanation:

Given:

Q = heat gained by the 15.71 gram mass of gold

Q=mc\Delta T +m\Delta H_{fusion}

\Delta T=(T_{final}-T_{initial})=(1064^oC-32^oC)=1032^oC

c = specific heat capacity of gold = 0.1291joules/gram^oC

m = mass of gold =15.71 g

Q=15.71 g\times 0.1291 joules/gram^oC (1032^oC) +15.71 g\times 63.5 Joules/gram

Heat gained by gold = 2093.0621 Joules + 997.585 Joules

=3090.6471 joules
