Identify the following as True or False?

Chemistry
1 answer:
slega [8]4 years ago
3 0

Answer :

(1) The limiting reactant is the reactant that is completely consumed in a chemical reaction.  → True

(2) The reactant in excess is any reactant that occurs in a quantity greater than that is required to completely react with the limiting reactant.  → True

(3) The amount of product can be calculated based on the amount of limiting reactant. → True

Explanation :

Excess reagent : It is defined as the reactants not completely used up in the reaction.  The given moles are more than the required moles.

Limiting reagent : It is defined as the reactants completely used up in the reaction.  The given moles are less than the required moles.

Theoretical yield : It is calculated from the amount of the limiting reagent present in the reaction.

Actual yield : It is experimentally determined.

All the given statements are true.

To use the gas law constant R=0.0821 the unit for temp should be kelvin and the unit for pressure should be atmospheres True or
hoa [83]

It is crucial to match your units of Pressure, Volume, number of mole, and Temperature with the units of R. If you use the first value of R, which is 0.082057 L atm mol-1K-1, your unit for pressure must be atm, for volume must be liter, for temperature must be Kelvin.

What is a limitation of using a chemical formula, such as C6H12O6, to represent a compound?
Kaylis [27]
The chemical formula does not show how the atoms are connected to one another.
When we write the chemical formula of any substance, we are not able to understand the spatial arrangement of that substance's atoms. This is extremely important in organic compounds, which exhibit different physical characteristics as well as different chemical characteristics due to the way their atoms are arranged in space. These isomers are known as enantiomers.

The radioactive atom 61/27 co emits a beta particle. write an equation showing the decay
pickupchik [31]

Answer:

\rm _{27}^{60}\text{Co} \longrightarrow \,  _{-1}^{0}\text{e} + \, _{28}^{60}\text{Ni}

Explanation:

The unbalanced nuclear equation is

\rm _{27}^{60}\text{Co} \longrightarrow \,  _{-1}^{0}\text{e} + \, ?

Let's write the question mark as a nuclear symbol.

\rm _{27}^{60}\text{Co} \longrightarrow \,  _{-1}^{0}\text{e} + \,  _{Z}^{A}\text{X}

The main point to remember in balancing nuclear equations is that the sums of the superscripts and the subscripts must be the same on each side of the equation.  

Then

60 = 0 + A, so A = 60 - 0 = 60, and

27 = -1 + Z, so Z  = 27 + 1 = 28

Your nuclear equation becomes

\rm _{27}^{60}\text{Co} \longrightarrow \,  _{-1}^{0}\text{e} + \, _{28}^{60}\text{X}

Element 28 is nickel, so the balanced nuclear equation is

\rm _{27}^{60}\text{Co} \longrightarrow \,  _{-1}^{0}\text{e} + \, _{28}^{60}\text{Ni}
