How can a neutral atom become a positively-charged particle?OA. It could lose protons.
B. It could lose electrons.
C.
It could gain neutrons.
D.
It could gain ions.

Answers

Answer 1

Answer:

Answer:

A neutral atom can become positively charged by loosing electrons

Explanation:

this is because the number of protons are the same as the number of electrons and so by loosing electrons there are now more protons and so they become positively charged

Answer 2

Answer:

Answer:

Explanation:

losing electrons,the atom becomes a cation ,,in other words becomes positively charged

What quantity of aluminium is deposited when a current of 10A is passed through a solution of aluminium salt for 1930s? (All=27,F=96500cmol)

Answers

The amount of aluminum deposited when a current of 10A is passed through a solution of aluminum salt for 1930s is 5.4 g.

What is electrochemical cell ?

An electrochemical cell converts chemical energy into electrical energy. Metals with higher negative electrode potential undergo oxidation and its ionization produces electron flow through the solution.

The weight of the metal that deposited by reduction is related to the mass of metal, current passed and time as follows:

w = z It

where z = E/96500 F

Equivalent mass of Al, E = 27 g

t = 1930 s

current I = 10 A.

Now, the weight of aluminum metal deposited is calculated as follows:

w = 1930 s × 10 A × 27/96500 = 5.4 g.

Therefore, the weight of Al deposited on the electrode is 5.4 g.

Answer:

AL*3+ + 3e- =AL.

（10A×1930）÷96500=0.2mole e-

0.2÷3×27=1.8g（AL）

what would happen if the cell wall in a plant cell just broke like all of them at the same time would it change the color or will it grow faster or will it die what will hapen

Answers

It would not change the color and it would not grow anymore. The cell wall is the outside layer of a plant, so if it eventually breaks off for some reason, it cannot grow anymore. Some plants can survive if their cell wall broke off, like a cactus. Cactuses can keep growing because it can be tall or short. (if someone like cut it in half or something, the cactus can still grow) Cactus does not have any leaves or anything connected to it (except for thorns) and if you break it, it can still grow.

Answer:

the cell will either

Pine trees, strawberry plants, and cacti are all plants. Name and describe three or morecharacteristics that you think scientists could use to separate these members of the Plant
kingdom into smaller groups.

Answers

Answer:

All plants present in the plant kingdom are separated by into smaller groups.The smaller groups contains plant species which are more similar to one another.

Some of the characteristics through which plant species can be separated are:

Gymnosperm or angiosperms: Pine are gymnosperm plants whereas strawberry plants are angiosperms. Cactus is also a gymnosperm.

Their location: Plants can be separated based on their habitats. For example, Cactus are desert- plants whereas pine and strawberries are not desert plants.

They are seed- producing plants or spore producing plants: pine are spore producing plants. Strawberry are seed-producing plants.

Final answer:

Pine trees, strawberry plants, and cacti can be separated based on leaf structure, growth habit, and reproduction.

Explanation:

Scientists could use several characteristics to separate pine trees, strawberry plants, and cacti into smaller groups. Three possible characteristics include:

Leaf structure: Pine trees have needle-like leaves, strawberry plants have broad, toothed leaves, and cacti have spines instead of leaves.
Growth habit: Pine trees are tall, woody plants, strawberry plants are low-growing and produce runners, and cacti are succulent plants with thick stems.
Reproduction: Pine trees reproduce through the production of cones, strawberry plants reproduce through the production of seeds in their fruit, and cacti reproduce through the production of offsets or pups.
