the ____ changes when electrons are gained or lost.
Answer: Matter changes when electrons are gained or lost.
Explanation:
The charge on an atom changes when electrons are gained or lost during chemical changes.
What is an atom?An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether it is solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.
The protons are positively charged particles and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral species and stable due to presence of oppositely charged particles.
Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

Will calcium metal react with chromium (III) chloride? Explain your answer
Calcium metal with chromium(III) chloride would react. Calcium metal is more reactive than chromium metal; therefore, putting calcium metal in chromium chloride would create a reaction, where as putting chromium metal in calcium chloride would not form any reaction.
Enter the correct ground-state (or lowest energy) configuration based on the number of electrons: 1s^4 2s^4 2p^12.
Express your answer in complete form in the order of orbital filling as a string without blank space between orbitals.
Answer:
The ground state configuration is the lowest energy, most stable arrangement. An excited state configuration is a higher energy arrangement (it requires energy input to create an excited state). Valence electrons are the electrons utilised for bonding.

You can begin your journey anywhere you’d like, but you must complete an entire cycle and end the journey where you began. Write your letter in complete sentences. Use each of the following terms correctly in your letter: • condensation • evaporation • precipitation • collection (HELP PLS ILL GIVE 54 points *all my points* AND GIVE BRAINLIEST HELP PLS)
Answer:
Explanation:
One day I was sitting on a leaf, in the early morning if a Tuesday, and I was just relaxing there. I then heard Bob( the water molecule next to me) say that he heard it was going to get pretty hot today. As the day went on I started to get pretty warm and I starting to evaporate and fly into the sky! It was really weird to see the world from up high. I stayed up there bouncing between clouds with Bob for a few hours, until the wind started to pick up and it got colder. I then started to shiver and began condensing with the other water molecules (and Bob). As it got colder we began to plummet to the earth really fast in the precipitate form of a water droplet. We hit the ground with a big ker-plop! I looked around me and we weren't the only ones. A bunch of other droplets had started to collect and form a puddle.

Why is there a large difference between day and night temperatures in a desert?
All rainfall in a desert happens at night.
There are no plants to trap the heat.
Heat escapes rapidly at night because the air is so dry.
The ground absorbs all heat. 20 points :,)
Answer: Heat escapes rapidly at night because the air is so dry.
Explanation: The desert has little humidity and rarely is cloudy. These two factors allow the desert to heat up rapidly during the day and cool off quickly at night.

When a solid air freshener gets smaller over time and runs out is it a physical change or chemical change? please say why?
Answer:
i think this would be an example of a physical change because here the substance is changing directly from a solid to a gas without passing through the liquid state which means that the composition of the substance has not changed and remains the same. This is also called sublimation.

In the cathode ray tube experiment, J.J. Thomson passed an electric current through different gases inside a cathode ray tube in the presence of
an electric field. In which two ways did this experiment change scientists' understanding of the atom?
O It showed that atoms combine in different proportions.
O It showed that atoms can be divided into smaller parts.
M It showed that all atoms of the same element are similar.
D
It showed that individual atoms could be destroyed
showed that all atoms contain electrons.
The two ways the cathode ray tube experiment changed scientists'
understanding of the atom was it showing that atoms can be divided into
smaller parts and all atoms contain electrons.
J.J Thompson was the scientist which performed the cathode ray tube
experiment and was able to ascertain it was negatively charged as a result
of it being deflected to the positive electrode.
His observation showed that the atoms contain sub-atomic particles called
electrons which are negatively charged.

A titration process is done by using 0.2M of 20 ml of third analytical group main reagent solution with 0.1 M nitric acid solution if nitric acid is replaced by sulphuric acid of same concentration, then the volume of sulphuric acid equals ……
Half the volume of nitric acid
Double the volume of nitric acid
The volume of nitric acid
Quarter the volume of nitric acid
Sulfuric acid undergoes dissociation reaction to produce twice the amount
of hydrogen ions produced by nitric acid in solution.
The volume of sulfuric acid equals; Half the volume of nitric acidReasons:
The concentration of the analytical group = 0.2 M
Volume of reagent = 20 ml
Concentration of the nitric acid to be replaced = 0.1 M
Replacement for the nitric acid = Sulfuric acid
Concentration of the sulfuric acid = Concentration of the nitric acid = 0.1 M
Reaction = Titration
Solution:
Sulfuric acid in solution gives; H₂SO₄ (aq) ⇄ 2H⁺ (aq) + SO₄²⁻(aq)
For nitric acid, we have; HNO₃ (aq) ⇄ H⁺(aq) + NO₃⁻(aq)
Therefore;
1 mole of sulfuric acid gives 2 moles of hydrogen ions
0.1 M solution of sulfuric acid gives 0.2 moles of hydrogen ions per liter
0.1 moles of hydrogen ions are therefore present in half a liter solution of 0.1 M sulfuric acid solution.
However;
0.1 M of nitric acid gives 0.1 moles of hydrogen ions per liter
Therefore;
The volume of sulfuric acid required = Half the volume of nitric acidLearn more about titration and quantitative chemical analysis here:
