Answer:

G) 50 mol

Explanation:

Given data:

Mass of methane = 800 g

Number of moles of CO₂ produced = ?

Solution:

Chemical equation:

CH₄ + 2O₂      →      CO₂ + 2H₂O

Number of moles of methane:

Number of moles = mass/molar mass

Number of moles = 800 g/ 16 g/mol

Number of moles = 50 mol

Now we will compare the moles of methane and carbon dioxide.

                 CH₄        :         CO₂

                    1           :          1

                  50          :        50

Which of the following has the greatest mass? (1pt)
Oduvanchick [21]

Answer:

C) 5 moles of Argon (Ar)

Explanation:

5mol Na x 22.990g Na/ 1 mol Na = 114.95g Na

5mol P x 30.974g P/ 1 mol P = 154.87g P

5mol Ar x 39.948g Ar/ 1 mol Ar = 199.74g Ar

Therefore Ar has the greatesr mass.

Please help with this chemistry question!
marusya05 [52]

Hey there!

Compounds with ionic bonds have higher melting points because of the forces needed to break through the strong forces of attraction holding it together.

Compounds with covalent bonds have lower melting points because less energy is needed to break the weaker forces of attraction.  

So, your answer is C. Compound 1 is ionic, and compound 2 is molecular.

Hope this helps!

Water enters a 4.00-m3 tank at a rate of 6.33 kg/s and is withdrawn at a rate of 3.25 kg/s. The tank is initially half full.
olga55 [171]

Answer:

At the start of the process, the volume not occupied by the water is 2 m3

Explanation:

At the start of the process you have a half full tank. It means that also a half is empty (not occupied by water).

Since the volume is 4 m3, 2 m3 are full (occupied by water) and 2 m3 (not occupied by water).

The volume in time will be

V(t)=V_0+(f_i-f_o)*t\\\\V(t) = 2 +(6.33/1000-3.25/1000)*t=2+0.00308*t \, \, [m3]
