Answer:
23.8g
Explanation:
1 mole of any gas contains 22.4L at stp.
This means that 1mole of CH4 also occupy 22.4L.
Now if 1mole of CH4 occupy 22.4L,
Then, xmol of CH4 will occupy 33.4L i.e
Xmol of CH4 = 33.4/22.4 = 1.49mole
Now, we can easily find the mass of CH4 by converting 1.49mole of CH4 to grams. This is illustrated below:
Molar Mass of CH4 = 12 + (4x1) = 12 + 4 = 16g/mol
Number of mole of CH4 = 1.49 mole
Mass of CH4 =?
Mass = number of mole x molar Mass
Mass of CH4 = 1.49 x 16
Mass of CH4 = 23.8g
Therefore, the mass of CH4 that has a volume of 33.4 L is 23.8g
Answer:
ratios of atoms, ions, molecules and/or formula units used in the equation
Explanation:
Symbolic representation of the chemical reaction with the help of the formulas and symbols is known as chemical equation. In the chemical equation, reactants are written at left-hand side as well as products are expressed or written on right-hand side. The coefficients which are written before the formulas or the symbols are known as stoichiometric numbers.
The balanced chemical equation shows the exact number of moles of the reactants which are equal to the moles of the products.
For example:-
The balanced combustion reaction of the oxidation of propane is shown below as:-
<u>Thus, Balanced chemical equation tells the stoichiometry of the reaction which is ratios of atoms, ions, molecules and/or formula units used in the equation.</u>
1- metaloids
2-increasing atomic mass (or) atomic number you choose
3-lustrous, malleable, ductile, and good conductors of heat and electricity
I got tired or answering lol hope those helped
C :)
I know this is right, I learned about this last year so I would really appreciate a brainliest
have a good day bud :)
Answer:
Explanation:
a) calculate the total avoidable cost in keeping the old machine and buy a new machine:
PARTICULARS KEEP OLD BUY NEW
AMOUNT($) AMOUNT($)
Opportuinty cost of buying 40,000
the old machine
Purchase price 150,000
Operating expenses
(50,000 × 4 years) 200,000
Operating expenses
18,000 × 4 years) 72,000
TOTAL AVOIDABLE COST 240,000 222,000
b)Decision:
Since the cost of operating the new machine is lower,it should be replaced
