If 0.400 moles CO and 0.400 moles O2 completely react, 17.604 grams of CO2 would be produced.
First, let us look at the balanced equation of reaction:

According to the equation, the mole ratio of CO and O2 is 2:1. But in reality, the mole ratio supplied is 1:1. Thus, CO is the limiting reactant while O2 is in excess.
Also from the equation, the ratio of CO consumed to that of CO2 produced is 1:1. Thus, 0.400 moles of CO2 would also be produced from 0.400 moles of CO.
Recall that: mole = mass/molar mass
Therefore, the mass in grams of CO2 that would be produced from 0.400 moles can be calculated as:
     Mass = mole x molar mass
                  = 0.400 x 44.01
                        = 17.604 grams

Answer:

Explanation:
<u>Molecular formula from Glucose:</u>
C₆H₁₂O₆
<u>3 moles of Glucose:</u>
3C₆H₁₂O₆
In 1 mole of Glucose, there are 12 hydrogen atoms.
<u>In 3 moles:</u>
= 12 × 3
= 36 H atoms

Answer: The temperature of the gas at a pressure of  0.987 atm and volume of 144mL is 
Explanation:
The combined gas equation is,
where,
 = initial pressure of gas = 0.947 atm
 = final pressure of gas = 0.987 atm
 = initial volume of gas = 150 ml
 = final volume of gas = 144 ml    
 = initial temperature of gas = 
 = final temperature of gas = ?
Now put all the given values in the above equation, we get:
The temperature of the gas at a pressure of  0.987 atm and volume of 144mL is 
 
        
             
        
        
        
Answer:
Iron is the densest out of the given options.
Explanation:
Oxygen
1.429 g/L
Water
1000 g/L
Hydrogen Peroxide
1450 g/L
Iron
7874 g/L
Iron Oxide
5240 g/L
 
        
             
        
        
        
The answer should be hydrogen bonding. Water only has oxygen and hydrogen in it, which are both nonmetals, so you know the answer cannot be metallic or ionic. It also cannot be nonpolar because the electronegativity of the oxygens will make the molecule polar. You can also know it is hydrogen bonding because it can only take place when a hydrogen is attached to an oxygen, fluorine, or nitrogen. These bonds are very strong attractions, so the molecules are extremely hard to pull apart, creating a high boiling point. Hope that helps!
