The salt which in solution gives a pale green precipitate with sodium hydroxide solutionanda white precipitate with barium chloride solution is?​

Answer:

92.4%

Explanation:

Assume 100g of the cathode material. The LiCoO2 cathode has 7.09 g of Li.  If half of Li migrates during charging, 3.55g Li migrates. 100g of the LiMn2O4 cathode contain 3.84g of Li. The fraction of lithium in LiMn2O4 that would need to migrate out of the cathode to deliver the same amount of lithium to the graphite anode:

(3.55g/ 3.84g ) * 100% = 92.4%

From electrolysis, 92.4% would need to migrate out of the cathode to deliver the same amount of lithium to the graphite anode.

Electrolysis is a technique that uses direct electric current (DC) to drive an otherwise non-spontaneous chemical reaction. Electrolysis is commercially important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell. The voltage that is needed for electrolysis to occur is called the decomposition potential.

Answer:

Explanation:

The wavelength of a wave can be found by using the formula

[tex]\lambda = \frac{c}{f} \\[/tex]

where

c is the speed of the wave

f is the frequency

From the question

c = 5 m/s

f = 2.5 Hz

We have

Answer:

Ans B)=====> Dorsal Horn

Two arms, each known as a Dorsal Horn, are formed by the core grey matter at the back of the spinal cord. In the image, the region labeled “ A “ is called the Dorsal Horn. Therefore, option B is correct.

One of the gray longitudinal columns discovered inside the spinal cord is the dorsal horn. Through the dorsal roots of the spinal nerves, it predominantly serves as the end of primary afferent fibers.

A complex network of excitatory and inhibitory interneurons, as well as projection neurons, make up the dorsal horn, which serves as an intermediary processing center for this information. It transmits the processed somatosensory information from the spinal cord to the brain.

The cell bodies of sensory neurons are located in the dorsal horns. The ventral horns are two arms of central grey matter that are found at the front of the spinal cord.

Thus, option B is correct.

collision theory is a theory used to predict the rates of chemical reactions, particularly for gases. The collision theory is based on the assumption that for a reaction to occur it is necessary for the reacting species (atoms or molecules) to come together or collide with one another

Answer:

Adding on to the answer said before, microscopes are pretty much one of the most significant tools used in Biology. It helped discover organelles, and smaller stuff like DNA, and prominently allowed Scientists to discover Bacteria and Archaea, the prokaryotic cells that contribute a big role in the functioning of soil, which is essential for our ecosystem.

The bond is polar covalent because the difference in electronegativity is greater than 0.4, but  less than 1.7.

Electronegativity refers to the ability of an atom in a compound to attract the electrons of the bond towards itself. It is a periodic trend that increases across the period but decreases down the group.

The electronegativity difference between the two atoms as shown in the question is 1.55. This means that the bond is polar covalent because the difference in electronegativity is greater than 0.4, but  less than 1.7.

This problem is providing information about the loss of mass for a reaction 50 °C as a function of the time elapse. Thus, when taking a look at the given graph, we can trace a horizontal line on the y-axis at 0.95 g in order to intercept it with the curve, and hence, figure out the time at which that loss of mass takes place.

Thus, we can see that when the loss of mass hits 0.95 g, the corresponding time on the graph is about 80 seconds, and hence, the rate of reaction turns out to be:

[tex]r=\frac{0.95g}{80s}\\\\r=0.012\frac{g}{s}[/tex]

Kinetic energy depends on the velocity of the object squared

Explanation:

Kinetic energy depends on the velocity of the object squared. This means that when the velocity of an object doubles, its kinetic energy quadruples. ... Kinetic energy must always be either zero or a positive value. While velocity can have a positive or negative value, velocity squared is always positive.

Answer:

Valence electrons are negatively charged particles located in the outermost shell of atoms that can be transferred or shared with other atoms. Valence electrons are important in chemistry because the number of valence electrons in a particular atom can be used to determine how the atom will react chemically with other atoms.

Since cream cheese has such a high fat content, it doesn't take long to come to room temperature if the room is relatively warm. It takes about thirty minutes on the counter to soften significantly, and about an hour to fully come to room temperature again, depending on the temperature outside and in your kitchen
