What is the percentage yield if 125.4g C3H8 are collected from a reaction that should produce 157.4g C3h8?
A. 58.3%
B. 79.2%
C. 44.2%
D. 26.3%
The percentage yield : 79.67%
The closest answer is option B.
Further explanationGiven
125.4 g C3H8
157.4 g C3H8
Required
The percentage yield
Solution
Percent yield is the comparison of the amount of product obtained from a reaction with the amount you calculated
General formula:
% yield = (actual yield : theoretical yield) x 100%
Input the value :
% yield = (125.4 : 157.4) x 100%
% yield = 79.67

Give the missing product Mg + Fe1Cl3 ---> Fe + _?_
The missing product : MgCl₂
Further explanationGiven
The reaction between Mg and FeCl₃
Required
The missing product
Solution
This reaction is a single replacement reaction
Occurs when one element replaces another element in the compound. The more active element will replace the less active element. The activity of this element can be seen from the voltaic series
Li-K-Ba-Ca-Na-Mg-Al-Mn- (H2O) -Zn-Cr-Fe-Cd-Co-Ni-Sn-Pb- (H) -Cu-Hg-Ag-Pt-Au
Mg is located to the left of Fe in the voltaic series so that it can replace Fe from its compound
General formula :
A + BC ⇒ AC + B
So the reaction :
3Mg + 2FeCl₃ → 2Fe + 3MgCl₂

Which of these is not an example your body maintaining homeostasis?
A
When exercising, your body releases more energy to your muscles.
B
On a hot summer day, you produce sweat.
C
When you get a virus, your body systems react to fight it.
D
When you see a piece of cake, your mouth waters.
Answer:
D
When you see a piece of cake, your mouth waters.
Explanation:
Homeostasis refers to the self-regulating processes in the human body to maintain stability and survival.
The example of homeostasis that does not occur in the body is:
Option D. When you see a piece of cake, your mouth waters.
The examples of homeostasis in the body are:
The body releases more energy to the muscles during exercises as the movement of muscles is required to main body temperature.Sweating is the process in which salt-based fluid or water is released from the body. It occurs to maintain the stable equilibrium and regulation of temperature. The immune system is tightly involved in the stability and survival of an organism. When a pathogen enters the body, the fighting cells will eliminate the pathogen maintain a normal physiological condition. The process of salivation is a part of digestion in the human body. It is not an example of homeostasis.Thus, the correct answer is Option D.

what element is [Kr]5s24d105p2
[Kr]5s²4d10⁵p² represents iodine element. The fundamental components of matter are thought to be the elements.
What is element?A material is considered an element if it cannot be divided into two or even more simpler compounds by any kind of chemical process, including the use of light or warmth. For instance, when melting the chunk of gold, it nevertheless melts but remains as the precious metal element.
The fundamental components of matter are thought to be the elements. There are currently 118 known elements, 94 of which are found in nature while the remaining 24 are created artificially. [Kr]5s²4d10⁵p² represents iodine element.
Therefore, [Kr]5s²4d10⁵p² represents iodine element.

Beryllium has a specific heat of 1.825 J/(g . °C). How many joules of heat energy are required to raise the temperature of 2.300 grams of beryllium from 22.00 to 60.00°C?
Heat required to raise the temperature = 159.505 J
Further explanationGiven
c = specific heat of Beryllium = 1.825 J/g C
m = mass = 2.3 g
Δt = Temperature difference : 60 - 22 = 38 °C
Required
Heat required
Solution
Heat can be formulated
Q = m.c.Δt
Input the value :
Q = 2.3 x 1.825 x 38
Q = 159.505 J

After a certain pesticide compound is applied to crops, its decomposition is a first-order reaction with a half-life of 56 days. What is the rate constant, k, for the decomposition reaction?
The rate constant, k, for the decomposition reaction : k = 0.0124 / days
Further explanationGiven
The half-life of 56 days
Required
The rate constant, k
Solution
For first-order, rate law : ln[A]=−kt+ln[A]o
The half-life : the time required to reduce to half of its initial value.
The half life :
t1/2 = (ln 2) / k
k = (ln 2) / t1/2
k = 0.693 / 56 days
k = 0.0124 / days
The rate constant for the decomposition reaction has been 0.0124/days.
The rate constant has been given by;
log [Final concentration] = kt + log [Initial concentration]
k has been the rate constant, and t has been the time.
The initial concentration has been 1, after the half life period the concentration has been half i.e. 0.5 .
The given half life has been 56 days.
The rate constant can be calculated as:
log 1 = k(56) + log 0.5
k(56) = 0.693
k = 0.0124/days.
The rate constant for the decomposition reaction has been 0.0124/days.

What is the relationship between temperature and reaction rate?
Explanation:
Temperature has a direct relationship with reaction rate. The higher the temperature the faster the rate of reaction of a system.
For every 10°C rise in temperature above the room temperature, it has been found that reaction rates becomes double or triple. When the temperature of a reacting system increases, the kinetic energy of each of the reacting particles increases. The frequency of collision and effective collision also increases per unit of time. Many of the reacting particles will acquire an energy greater than or equal to the activation energy of the reaction.Lithium has two stable isotopes, lithium-6 and lithium-7. The atomic number of lithium is 3. Explain how the two are the same and how they are different.
Explanation:
The two isotopes of lithium given are similar in the sense that they have the same atomic number which is 3.
Every kind of an atom of an element have the same atomic number. Atomic number is the number of protons in an atom.
The atoms are different in that they have different mass number because the number of protons they contain are different.
So for isotopes;
They have the same electronic configurationThey have similar chemical propertiesBut their masses differsTheir abundance in nature also differs.
