B is the limiting reactant in this equation.
What is the limiting reactant?The limiting reactant is the reactant that is present in the smallest amount in the system. The continuity of the reaction depends on the concentration of the limiting reactant.
It must also be said that the reactant that yields the least amount of product is the limiting reactant. We know that; A(g) + 5B(g) -----> 3C(g) + 4D(g).
We can see that;
1 mole of A gives 3 moles of C
5 moles of B gives 3 moles of C
1 mole of B gives 3/5 moles of C
Thus, B is the limiting reactant in this equation.

Which of the following accurate describes the atmospheric conditions required for the formation of clouds
Answer:
To make a cloud, air needs only to be cooled to saturation and beyond. ... Usually the water vapor amounts in air are less that this amount. When this is the case, we describe the air as being unsaturated. If we add more vapor to such air, we could reach the maximum for the temperature

The atmospheric conditions required for the formation of clouds are , air needs only to be cooled to saturation and beyond formation of clouds and precipitation.
What is precipitation?
Precipitation is defined as any liquid or frozen water which forms in the atmosphere and then gets received on Earth.It is one of the most important steps of the water cycle.
Precipitation takes place in form of clouds when water vapor gets accumulated in clouds and they get bigger and heavy, when the clouds become heavy enough they fall to the land in the form of rain.f a cloud is present at higher altitudes , the water present in the clouds freezes and fall to the ground in form of snow,hail.
Precipitation occurs always in case of fresh water because the sea salt does not evaporate with the water.The different types of precipitation are rain, drizzle,snow,snow hail,etc.

which physical method can separate a mixture of steel ball bearings and marbles? boiling evaporation filtration
Steel ball bearings and marbles can be separated through manual sorting due to their difference in appearance.
Before answering the question, let us define the given choices.
The boiling separation technique is used when the boiling points of the components of a mixture are different. It is mostly done for the separation of homogeneous mixtures. The evaporation separation technique is usually used for the separation of a solvent and a soluble solid. Enough heat is provided for the solvent to be evaporated. The process is also slower compared to the boiling separation technique. Filtration is used to separate insoluble solid particles from the liquid. Materials such as filter paper are used in this process.The given separation techniques are not suitable for the separation of steel balls bearings, and marbles. Instead, the sorting separation technique must be used. This is used for manually sorting coarse materials based on their physical characteristic, which in this case is their difference in appearance.

Use the solubility table to predict if a precipitate will form in the double replacement reaction. if yes identify the precipitate.
CuSO4 + 2KOH -> Cu(OH) + K2SO4
Answer:
A precipitate will be formed, it will be Cu(OH)2.
Explanation:
This is due to it's solubility.
There will be a precipitate due the solubility which will be result in the Cu(OH)2 precipitate.
What is double replacement reaction?A double replacement reaction is a chemical reaction in which two reactant and product exchange cations or anions to produce two new products.
Double replacement reactions are also referred to as double displacement reactions or metathesis reactions.
The simplest way to detect a double displacement reaction is to see if the cations exchanged anions with one another.
If the states of matter are mentioned, look for soluble reactants and the creation of a single solid product, as the reaction typically produces a precipitate.
As a result of the solubility, a precipitate will form, resulting in the Cu(OH)2 precipitate.
Thus, this is the result of the reaction.

What is the percent yield if 155 grams of calcium carbonate is treated with 250 grams of hydrichloric acid andb142 grams of calciym chloride is obtained
Answer:
375 grams
Explanation:
The percent yield if 155 grams of calcium carbonate is treated with 250 grams of hydrochloric acid and 142 grams of calcium chloride is obtained is 82.55%
What is percent yield?Percent yield is defined as the amount of product actually made compared with the maximum calculated yield. It is the ratio of actual yield to the theoretical yield.
Mass of calcium carbonate = 155 g
Mass of HCl = 250g
Mass of calcium chloride product = 142 g
Moles of calcium carbonate = 155 / 100 = 1.55 moles
Moles of HCl = 250 / 36.5 = 6.85 moles
Mass of calcium chloride = Moles x Molar mass
= 1.55 mole x 111 g/ mole
= 172 g /mole
Theoretical yield = 172 g
Actual yield = 142 g
Percent yield = Actual yield / Theoretical yield x 100
= 142 / 172 x 100
= 82.55 %
Thus, the percent yield if 155 grams of calcium carbonate is treated with 250 grams of hydrochloric acid and 142 grams of calcium chloride is obtained is 82.55%

How are a peacock, a jellyfish, and a birch tree similar?
They all share genetic information.
They all contain carbon.
They all reproduce the same way.
They all obtain energy in the same way.
Answer: B
Explanation: intook the test
They all share genetic information as DNA, shaping their unique traits and functions through evolutionary processes.
Option (A) is correct.
The similarity among a peacock, a jellyfish, and a birch tree lies in the fact that they all share genetic information encoded in their DNA. Genetic information is the blueprint that determines an organism's traits, functions, and characteristics. Despite their diverse appearances and habitats, all living organisms, including these three examples, utilize DNA to carry hereditary instructions.
However, it's important to note that while they share genetic information, the way this information is expressed and the specific traits it codes for differ significantly among these organisms due to variations in their evolutionary history, adaptations, and environmental interactions.
This shared genetic foundation underscores the fundamental biological unity among all living beings on Earth, while the unique expression of this genetic information contributes to the incredible diversity of life forms.

WHY: You can abbreviate an element's electron configuration using the noble gas notation method because when you get down to the lower elements, specifically the d's and the f's, the electron configuration will be very long. The noble gas notation method is a faster answer while also being correct.
HOW: We can abbreviate an element's electron configuration by finding the last noble gas a specific element passed, for example calcium would have just passed Argon. Once you have the "address" of the previous noble gas, then you add on the difference between the element chosen and the noble gas, for example calcium would be [Ar] 4s^2.
