Answer:

kindly check the explanation section.

Explanation:

The largest rice cake in the world was discovered in the year 2007 in South Korea with a weight of 8,113 lb. The amount of energy in the World's largest rice cake can be determined by using the formula below:

The energy in kJ =[ mass of water] x [specific heat capacity of water] x [change in temperature].

In order to determine experimentally in the laboratory and make use of the formula above. The first thing[STEP ONE] to do is to measure the mass of the rice cake and record it.

STEP TWO: measure a known amount of water in a boiling tube.  

STEP THREE: Heat the rice cake until it catches fire with a Bunsen flame.

STEP FOUR: Use the rice cake that has already caught fire in step three above and use it to heat the water in step two until the fire burns out.

Repeat the process for three to four times and record your observations under the following headings;

[1]. Mass of cake, [2]. Temperature  of water  before  burning, [3]. Temperature  of water after  burning and Temperature  increase per  gram of the rice cake.

How many grams of NH3 can be prepared from 85.5 grams of N2 and 17.3 grams of H2 ?
Tcecarenko [31]
N2 + 3H2 ---> 2NH3

mass of N2 = 28g
mass of H2 = 2g
mass of NH3 = 17g

according to the reaction:
28g N2----------------- 3*2g H2
85,5g N2-------------------- x
x = 18,32g H2 >>>  so, nitrogen is excess

according to the reaction:
2*3g H2---------------------- 2*17g NH3
17,3g H2 ------------------------- x
x = 98,03g NH3

<u>answer: 98,03g of NH3</u>

What is the name of the functional group that is attached to this hydrocarbon? The first and last of a chain of three carbons ar
disa [49]

Answer:

Ketone

Explanation:

As you are stating here, we have a carbonated chain of three carbons, and the first and last has 3 Hydrogens, then this means that we have CH₃ . The center carbon is a carbon double bonded to oxygen.

In general terms this belongs to the carbonyl group. However, this alone does not represent a functional group, but when it's in a chain with other radycals or chains, it becomes a functional group.

In this case, the molecule you are talking here is the following:

CH₃ - CO - CH₃

This molecule is known as the Acetone, and has the general form of:

R - CO - R'

Which belongs to a ketone as a functional group.

What is the benefit of having a limiting reagent when performing a lab experiment
Shalnov [3]

Answer : The role of limiting reagent or reactant is important in a chemical reaction because it can help the chemist to predict that complete amount of reactant is consumed, as it is limiting the reaction, only required moles of products can get formed instead of the theoretical yield where the perfect amount is used.


In short, Limiting reactant in a chemical reaction is the substance that is totally consumed when the chemical reaction is found to be complete.
