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.
normalizes the stress.
increases the stress.
changes the stress.
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.

When we drink water, it is absorbed into our blood through the digestive tract. If the concentration of water in body cells is low, cells must get water from the blood. What process allows water to enter body cells from the blood?
Answer:
Osmosis
Explanation:
Water is very essential for the body. When we drink water, our blood cells absorbs water from the body. This happen by a process called as osmosis process. Osmosis is type of diffusion process.
Water along with oxygen and carbon dioxide are some of the simple molecules that moves into the blood cell. Osmosis is the process by which water molecules passes into the cell bodies through its semi permeable membrane.

What happens in this circuit if one of the light bulb burns out?
1. Both light bulbs will stop glowing
2. The other light bulb will stay on but get dimmer
3. the other light bulb will stay on and glow more brightly
4. the battery will lose its charge and stop working
Answer:
option 3
Explanation:
it is so because when both bulbs were there It took more electricity to charge both of them. now since only one is there it takes the power that is produced which made the other bulb glow and uses it for itself.

Which statement best compares potential and kinetic energy?
Objects always have more potential energy than kinetic energy.
Kinetic energy increases and potential energy decreases when the velocity of an object increases.
Only potential energy decreases when an object’s height increases.
Objects always have more kinetic energy than potential energy.
Answer:
Its B) Kinetic energy increases and potential energy decreases when the velocity of an object increases.
Explanation:
because i took the test on edge 2020
Taking into account the definition of kinetic, potencial and mechanical energy, the tatement that best compares potential and kinetic energy is: Kinetic energy increases and potential energy decreases when the velocity of an object increases.
Kinetic energyKinetic energy is a form of energy. It is defined as the energy associated with bodies that are in motion.
Kinetic energy is defined as the amount of work necessary to accelerate a body of a given mass and at rest, until it reaches a given speed. Once this point is reached, the amount of accumulated kinetic energy will remain the same unless there is a change in speed or the body returns to its state of rest by applying a force.
The kinetic energy is represented by the following expression:
Ec= ½ mv²
Where:
Ec is the kinetic energy, which is measured in Joules (J).m is the mass measured in kilograms (kg). v is the speed measured in meters over seconds (m/s).Potential energyPotential energy is the energy that measures the ability of a system to perform work based on its position.
Gravitational potential energy is the energy associated with the gravitational force. This will depend on the relative height of an object to some reference point, the mass, and the force of gravity as follow:
Ep= m×g×h
Where:
Ep is the potential energy in joules (J).m is the mass in kilograms (kg).h is the height in meters (m).g is the acceleration of fall in m/s² (approximately 9.81 m/s²).Mechanical energyFinally, mechanical energy is that which a body or a system obtains as a result of the speed of its movement or its specific position, and which is capable of producing mechanical work. Then:
Potential energy + kinetic energy = total mechanical energy
Principle of conservation of mechanical energyThe principle of conservation of mechanical energy indicates that the mechanical energy of a body remains constant when all the forces acting on it are conservative (a force is conservative when the work it does on a body depends only on the initial and final points and not the path taken to get from one to the other.)
Therefore, if the potential energy decreases, the kinetic energy will increase. In the same way, if the kinetics decreases, the potential energy will increase.
Statement best compares potential and kinetic energyTaking into account the definition of kinetic energy, when the velocity of an object increases the kinetic energy increases.
Therefore, considering the principle of conservation of mechanical energy, the potential energy decreases.
So, the correct answer is the second option: Kinetic energy increases and potential energy decreases when the velocity of an object increases.

True or False. It is reasonable to assume that an atom with a positive oxidation number could make a chemical bond with an atom having negative oxidation number. And why?
A loss of negatively-charged electrons corresponds to an increase in oxidation number, while a gain of electrons corresponds to a decrease in oxidation number. Therefore, the element or ion that is oxidized undergoes an increase in oxidation number.

Calculate the number of protons and neutrons for ²⁴Mg and 88Sr.
Answer:
12 protons and 12 neutrons are present in Mg and
38 protons and 50 neutrons are present in Sr
Explanation:
Answer:
For ²⁴Mg
1. Proton number = 12
2. Neutron number = 12
For ⁸⁸Sr:
1. Proton number = 38
2. Neutron number = 50
Explanation:
For ²⁴Mg:
1. Determination of the number of proton.
The atomic number of an element is simply defined as the number protons in the atom of the element. The atomic number of ²⁴Mg is 12 since no two elements have the same atomic number.
Atomic number = 12
Proton number = Atomic number
Proton number = 12
2. Determination of the Neutron number.
Mass number = 24
Proton number = 12
Neutron number =?
Mass number = Proton + Neutron
24 = 12 + Neutron
Collect like terms
Neutron = 24 – 12
Neutron number = 12
For ⁸⁸Sr:
1. Determination of the number of proton.
The atomic number of ⁸⁸Sr is 38.
Atomic number = 38
Proton number = Atomic number
Proton number = 38
2. Determination of the Neutron number.
Mass number = 88
Proton number = 38
Neutron number =?
Mass number = Proton + Neutron
88 = 38 + Neutron
Collect like terms
Neutron = 88 – 38
Neutron number = 50
A green pea plant (Gg) is crossed with a yellow pea plant (gg). What is the probability that the offspring will be heterozygous?

Answer:
50 percent
Explanation:
G g
g Gg gg
g Gg gg
since one of the plants are already heterozygous, only half will be heterozygous since the other plant is homzygous
There is 50% probability that the offspring will be heterozygous.
What is heterozygous?At a given gene locus, the existence of two different alleles. One normal allele and one mutant allele, or two separate mutated alleles, can make up a heterozygous genotype (compound heterozygote).
what is allele?An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome.
so, if green pea plant (Gg) is crossed with a yellow pea plant (gg), there will be 50% probability that the offspring will be heterozygous, we can find it by making punnett square so here is the solution
Hence, the correct option is B i.e. 50%

A molecule contains 24.36 g of nitrogen and 62.64g of sliver
Answer:
This molecule is AgN3
Explanation:
Answer:
AgN3
Explanation:
Mass of nitrogen N is given as 24.36 g
Molar mass of nitrogen N= 14 g/mol.
amount of substance in mol of N = mass/molar mass
=24.36 g/ 14 g/mol.
=1.74 mol.
Given mass of silver= 62,64 g.
Molar mass of silver Ag=107.87 g/mol
Number of mols=62.64 g ÷ 107.87 g/mol.
=0.58 mol.
Ratio of number of mol of N and number of mols of Ag = 1.74 mol / 0.58 mol
=3:1
Hence, empirical formula is AgN₃.
