Explanation:
IONIC-
metal & nonmental
1st word doesn't start with "mono"
2nd word can end in "-ate or -ite" (Polyatomic ions)
May need roman numerals
Reduce charges when writing formula
COVALENT-
2 non-metals
Names uses prefixes
2nd word can end in - ide
BOTH-
2nd element is a non-metal
Answer:
See explanation
Explanation:
We have to remember that for any <u>equilibrium expression constant</u> we can use the general reaction:
With a equilibrium expression:
We have to <u>divide products by reagents and use the coefficient (in the balanced reaction) as exponents</u>. So:
The reaction is <u>already balanced</u>. So, we can write the equilibrium expression:
In this case, all the compounds have <u>gaseous state (g)</u>. So, we can change the concentration ([]) by the <u>pressure of each compound</u>:

Answer:
2.8 × 10² g
Explanation:
Given data
Step 1: Convert 25°C to the absolute scale
When working with gases, we have to convert the temperatures to the Kelvin scale, using the following expression.
K = °C + 273.15 = 25°C + 273.15 = 298 K
Step 2: Calculate the moles of chlorine gas
We will use the ideal gas equation.
Step 3: Calculate the mass of chlorine gas
The molar mass of Cl₂ is 70.91 g/mol. Then,
Tetracarbon dioxide is an oxide of carbon, a chemical compound of carbon and oxygen, with chemical formula C4O2 or O=C=C=C=C=O. It can be regarded as butatriene dione, the double ketone of butatriene . Chemical formula
C4O2
Molar mass
80.042
