How moles are in 45.7g of CH3?
miskamm [114]

first find the atomic weight of CH3 which would be

atomic weight: 12.011 (3×1.008) = 36.32 g/mol

then find the moles in the given mass

36.32 ÷ 45.7 = 0.794

A team of engineers is doing a cost-benefit analysis to determine whether
beks73 [17]

Answer:

1) The risk of high cost due to increased resource requirements

2) The risk of late entry into the (a changed) market

Explanation:

The analysis being performed by the engineers = A cost benefit analysis to determine if a new technology should be developed

A cost-benefit analysis is a process of appraising or measuring the advantages, benefits of a policy, action or decision, so as to find the (equilibrium) balance point between the costs of the decision or action

The risk to be considered are;

1) The risk of high cost due to increased resource requirements

The increased cost required for the development of the new technology now which due to the unlikely existence of a similar invention in the market that will give them an advantage of increased profits

2) The risk of late entry into the (a changed) market

The changes in the consumer preferences, market landscape, and the likely introduction into the market of a similar invention by the competition in the near future which will reduce the amount of profits that can be gained from the invention

PLEASE HELP ME SOLVE THIS.Thank you so much!
Tju [1.3M]

Answer: The coefficients for the given reaction species are 1, 6, 2, 3.

Explanation:

The given reaction equation is as follows.

Cr_{2}O^{2-}_{7} + Cl^{-} \rightarrow Cr^{3+} + Cl_{2}

Now, the two half-reactions can be written as follows.

Reduction half-reaction: Cr_{2}O^{2-}_{7} + 3e^{-} \rightarrow Cr^{3+}

This will be balanced as follows.

Cr_{2}O^{2-}_{7} + 14H^{+} + 6e^{-} \rightarrow 2Cr^{3+} + 7H_{2}O ... (1)

Oxidation half-reaction: Cl^{-} \rightarrow Cl_{2} + 1e^{-}

This will be balanced as follows.

6Cl^{-} \rightarrow 3Cl_{2} + 6e^{-} ... (2)

Adding both equation (1) and (2) we will get the resulting equation as follows.

Cr_{2}O^{2-}_{7} + 14H^{+} + 6Cl^{-} \rightarrow 2Cr^{3+} + 3Cl_{2} + 7H_{2}O

Thus, we can conclude that coefficients for the given reaction species are 1, 6, 2, 3.

(I00p)A chemical equation example of a replacement of 1 ion for another in a compound! I need an example
snow_tiger [21]
A single replacement reaction could look like this:

2FeCl3 + 3Ba ➡️ 3BaCl2 + 2Fe

In this reaction, the barium is replacing the iron bound to the chlorine.
