Answer:
its A reduces stress :)))
Explanation:
According to Le Chatelier’s principle, a system in chemical equilibrium responds to stress by shifting the equilibrium in a direction that reduces the stress.
What is Le Chatelier’s principle ?Le Chatelier’s principle states that when a chemical equilibrium become imbalance by any change such as change in concentration, temperature, pressure etc. the system will reduces this stress by creating a new equilibrium state.
By this principle, when temperature increases for an endothermic system, forward reaction will takes place more since the temperature is absorbed there.
Similarly, when the concentration of any reactant increases, the reaction will turn to that direction in which that reactant is consumed more. If any loss the volume, then the equilibrium will shifts to that direction in which the that substance is produced.
Hence, the system will somehow manage the imbalance by reducing the stress occurred.

manganese atom has 30 neutrons and atomic number 25
calculate the atomic mass of manganese atom
The atomic mass of manganese atom : 55
Further explanationGiven
Manganese (Mn) atom has 30 neutrons
atomic number 25
Required
the atomic mass
Solution
The atomic mass=number of protons+number of neutrons
The atomic number = number of protons=number of electrons
The number of protons=25, so the atomic mass :
[tex]\tt =ptotons+neutrons\\\\=25+30\\\\=55[/tex]

Explanation:
A chemical reaction that has the general formula of AB + C → CB + A is best classified as a
synthesis
polymerization
decomposition
oxidation
replacement
reaction.
Replacement reaction.
Further explanationGiven
A chemical reaction
AB + C → CB + A
Required
reaction type
Solution
There are several types of reactions that can occur
synthesis: 2 elements combine to form a single product
polymerization: monomers combine to produce a polymer
decomposition: One compound breaks down into 2 components
oxidation : a change in oxidation number
replacement can be divided into 2
single replacement if one element replaces the other elements of a compound
double replacement if there is an ion exchange between two ion compounds in the reactant to form two new ion compounds
AB + C → CB + A
If we look at this reaction, element C replaces element A to form a new compound CB. So it is single replacement. But this reaction can also be said to be an oxidation-reduction reaction because there is a change in oxidation number
element A undergoes a reduction reaction
element C undergoes an oxidation reaction
So types of redox reactions can be combination, decomposition, displacement, combustion, and disproportion.

oxidation

Convection currents in Earth's mantle are caused by the rise of hot material rising towards the crust, becoming cooler and sinking back down. This process occurs repeatedly, causing the currents to constantly flow. The movement of the currents plays a factor in the movement of the mantle.
Answer:
True or False
Answer - True
Explanation:
The mantle convection clearly describes how the mantle moves, transferring heat from the white-hot core to the lithosphere. The mantle is usually being heated below and the cooling happens above and the general temperature of the area gets dropped over a long period of time.
Hot buoyant Magma is being transferred through convection currents, to the lithosphere at the plate boundaries and hot spots. Also, convection current moves cooler materials from the crust to the interior of the earth through a process that is widely known as subduction.

Which of the following are common decomposers? (Select all that apply) fungi, ferns, bacteria, viruses, grasses
Answer:
Fungi, bacteria, ferns,
Explanation:
bacteria Fungi Ferns are important. decomposers,
I hope it helps you.
There are basically four different categories of decomposers: fungi, insects, earthworms, and bacteria. Fungi, ferns and bacteria are common decomposers.
What are decomposers ?Decomposers are organisms that disintegrate rotting or dead species; they carry out decomposition, a process only some kingdoms, like fungi, are capable of.
The primary decomposers in nature are fungi, which destroy organic material that would otherwise not be recycled.
Scavengers and decomposers are the two different categories of decomposers. Animals called scavengers hunt down dead plants or animals and consume them. They cut them into small pieces when they eat them.
Each contributes to the food recycling process differently. To transform dead plants or animals into simple substances, fungi release compounds. Some of these elements are absorbed by them for growth, while others go into the soil.
Thus, Fungi, ferns and bacteria are common decomposers.

Scientific Notation consists of 2 parts
1. the first part: the first digit followed by the decimal point
2. The second part: the power of 10 (the exponents).which shows the number of digits after the decimal point
To add/subtract, the exponents must be the same and then add/subtract the coefficient
convert the largest exponent (7 x 10⁻⁸)7 x 10⁻⁸ = 700 x 10⁻¹⁰
add the coefficients[tex]\tt =(3.5+700)\times 10^{-10}\\\\=703.5\times 10^{-10}\\\\=7.035\times 10^{-8}[/tex]

A student calculates the density of an unknown solid. The mass is 10.04 grams, and the volume is 8.21 cubic centimeters. How many significant figures should appear in the final answer
Answer:
1.22 g/cm³
Explanation:
Density = mass ÷ volume
Mass = 10.04 grams
Volume = 8.21 cubic centimeters
Density = mass ÷ volume
= 10.04 ÷ 8.21
= 1.2228989037758 g/cm³
Approximately
1.22 g/cm³ to 2 significant figure.
The final answer should be approximated to 2 significant figure because the mass and volume of the objective given is in 2 significant figure
