5. In a general chemistry laboratory experiment, a student produces 2.73 g of a compound. She calculates the

1 answer:

8 0

The percent yield is given by the actual and the theoretical yield. The percent yield of the 2.73 gm compound is 80.3%. Thus, option b is correct.

<h3>What is the percent yield?</h3>

The percent yield is the ratio of the actual yield to the theoretical yield. It is calculated as:

% Yield = Actual yield ÷ Theoretical yield × 100%

= 2.73 ÷ 3.84 × 100%

= 71.09 %

As the closest number to 71.09 is 80.3% the percent yield will be 80.3%.

There is no limiting reagent in the reaction between the copper iodide and mercury iodide as the moles of the reactants and the products are in equal quantity.

Hence, option b. there is no limiting reagent in this reaction.

What is the name for this type of reproduction?

mario62 [17]

Answer:

----------------------------------------------

Reproduction is defined as the production of individuals of the same species, that is the next generation of the species.

----------------------------------------------

There are basically two types of reproduction - asexual and sexual.

----------------------------------------------

Asexual reproduction involves only one parent and the offspring is

genetically similar to the parent ...

----------------------------------------------

The different types of asexual reproduction are fission, budding, fragmentation, spore formation and vegetative propagation.

----------------------------------------------

Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete (such as a sperm or egg cell) with a single set of chromosomes combines with another to produce a organism composed of cells with two sets of chromosomes .

Asexual reproduction is a type of reproduction which does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from a single cell or from a multicellular organism inherit the genes of that parent.

An copper mass is heated and placed in a foam cup calorimeter containing 45.0 mL of water at 24.0 degrees celcius. The water rea

Alenkinab [10]

Answer:

= 9,593.1 Joules

Explanation:

Heat absorbed by water is equivalent to heat released by copper.

Heat absorbed is given by;

Q = mcΔT

where m is the mass, c is the specific capacity and ΔT is the change in temperature.

Therefore;

Since dnsity of water is 1 g/mL, and specific heat capacity is 4.18 J/g°C while the change in temperature is (75-24) = 51°C.

Heat absorbed by water = 45 g × 4.18 J/g°C × 51

= 9,593.1 Joules

Therefore, the heat released by copper is 9,593.1 Joules

Answer:

$n=0.0747mol$

Explanation:

Hello,

In this case, since we can consider hydrogen gas as an ideal gas, we check the volume-pressure-temperature-mole relationship by using the ideal gas equation:
