Answer:
We will produce 8.0 moles of HCl , this is 291.7 grams HCl
Explanation:
Step 1: Data given
Number moles of H2S = 3.0 moles
Step 2: The balanced equation
2HSbCl4 + 3H2S → Sb2S3 + 8HCl
Step 3: Calculate moles HCl
For 2 moles HSbCl4 we need 3 moles H2S to produce 1mol Sb2S3 and 8 moles HCl
For 3.0 moles H2S we'll have 8.0 moles HCl
Step 4: Calculate mass HCl
Mass HCl = moles HCl * molar mass HCl
Mass HCl = 8.0 moles * 36.46 g/mol
Mass HCl = 291.7 grams
We will produce 8.0 moles of HCl , this is 291.7 grams HCl

Explanation:
Air molecules are too far to disperse heat energy to one another efficiently. Heat is conducted by molecules and atoms that are very closely bonded together and vibrating at high frequency.
Answer:
option D
Explanation:
Given,
V₁ = 285 L
P₁ = 530 mm Hg
Standard pressure
P₂ = 760 mm Hg
V₂ = ?
Using relation between pressure and volume
Hence, volume of the propane at standard pressure is equal to 198.8 L.
Hence, the correct answer is option D.
The correct answer among the choices given is the last option A pH reading of 10 represents a basic solution. pH is a measure of the concentration of hydrogen ions of the substance. Solutions that have more OH– than H+ ions are bases. These are substances that are slippery to touch and has an astringent taste. It reacts with acids in a neutralization reaction forming salts.
