Answer:

Na₂SO₃

Explanation:

We can use the criss-cross method to work out the formula.

1. Write the symbols of the anion and cation.

Na¹⁺ SO₃²⁻

2. Criss-cross the numbers of the charges to become the subscripts of the other ion (see image).

3. Write the formula with the new subscripts.

Na₂(SO₃)₁

4. Omit all subscripts that are 1.

The formula becomes Na₂SO₃.

1. How is energy being used inefficiently?

ANTONII [103]

Answer:

1. Energy intensity (primary energy consumption divided by GDP) for the world and various countries. The lower the value, the less energy is used to generate economic output, so lower means more efficient in a sense.

2.Lower Your Thermostat. Adopt the habit of lowering the temperature on your thermostat while away from home.

Start a Compost Pile.

Install Low-Flow Showerheads.

Seal All Windows.

Limit Space Heater Use.

Turn Off Unnecessary Water.

Replace Incandescent Bulbs.

What is the mass in grams of 2.50 mol of ammonia vapor, NH3?

Crank

Molar mass:-

$\\ \tt\longmapsto 14+3(1)=17g/mol$

Now

$\\ \tt\longmapsto Given\:mass=No\;of\:moles\times Molar\;mass$

$\\ \tt\longmapsto Given\:mass=17(2.5)$

$\\ \tt\longmapsto Given\:mass=42.5g$

How many grams of lithium hypochlorite (LiClO) are there in 0.594 moles?

Flauer [41]

Answer : The mass of lithium hypochlorite are, 34.7 grams.

Explanation : Given,

Moles of $LiClO$ = 0.594 g

Molar mass of $LiClO$ = 58.4 g/mol

Expression used :

$\text{ Mass of }LiClO=\text{ Moles of }LiClO\times \text{ Molar mass of }LiClO$

Now put all the given values in this expression, we get:

$\text{ Mass of }LiClO=(0.594moles)\times (58.4g/mole)$

$\text{ Mass of }LiClO=34.7g$

Therefore, the mass of lithium hypochlorite are, 34.7 grams.
