Answer:
B. A harmful compound can become harmful when its elements are seperated.
Explanation:
In the question, common table salt, NaCl was the illustration.
NaCl is a crystalline solid whjch has different benefits like for preservation, add taste to foods etc. NaCl is generally consumed by humans daily and is found readily. This goes to show that NaCl is a harmless compound but the individual elements that is, Soduim and Chlorine gas,
2Na + Cl2 --> NaCl
Soduim metal is a reactive and unstable element with 1 (valence) electron in its outer shell. Hence why the reaction of sodium strips with water is explosive.
Chlorine gas is very poisonous, unstable as well as reactive because of the 7 (valence) electrons in its outermost shell.
Which chemical formula represents a polyatomic ion?
Answer:CIO^-
Explanation: just took the quiz, and I got it right
Polyatomic ions describes ions which are posses more than one atom. Hence, the formula which represents a polyatomic atomic ion is [tex]SO_{4}^{2-} [/tex]
Sulphates contain both Sulphur and Oxygen atoms, hence, they contain two atoms, thus they are polyatomic. Sulphide are represented as [tex]S^{2-} [/tex] ; containing only Sulphur atom, hence, they are mono atomic. Chlorides are represented as [tex]Cl^{2-} [/tex] ; containing only chlorine atoms, hence, they are mono atomic. Nitrides are represented as [tex]N^{3-} [/tex] ; containing only Nitrogen atom, hence, they are also mono atomic.Therefore, sulphates are polyatomic as they contain more than one atom.

consider equimolar samples of the same ideal gas at the same volume, but different temperatures. sample c is at a higher temperature than sample d.
Answer:
The question is incomplete.
This is the complete question:
Consider equimolar samples of different ideal gases at the same volume and temperature. Gas A has a higher molar mass than gas B.
Compare the pressures. Compare the rms speeds. Compare the average kinetic energies.
Answer:
pressure: A = B
RMS: A < B
kinetic energies: A = B
Explanation:
1) Pressure:
You can deal with this part of the question on the basis of Avogaro's principle which stated that equal volumes of gases at same temperature and pressure have the same number of particles (molecules).
Also, kinetic theory of gases postulates that the particles of gas are quited separated and in consequence the volume occupied by the particles of a gas is meaningless and does not influence the total volume occupied by a fixed number of particles.
Also, you can use the equation of ideal gases pV = nRT, from which p = nRT/V. if n, T, and V are fixed, then p is fixed.
The three approaches leads to the same conclusion.
Then, pressure of gas A is equal to pressure of gas B.
2) RMS
RMS stands for root mean square speed.
It is the room mean square speed of the particles of a gas.
the RMS is related with the temperature of the gas and the molar mass per this equation:
RMS = √(3RT/M), where R is the universal constant of gases, T is the absolute temperature and M is the molar mass.
Then, the greater the molar mass, the lower the RMS, which permits you conclude that the RMS of gas A is less than the RMS of the gas B.
3) kinetic energy
Temperature is a measure of the kinetic energy.
Equal temperatures of the gas means equal kinetic energies.
The Kinetic Molecular Theory states that the average energy of molecules is proportional to absolute temperature.
So, you conclude that the same amount of gases, at the same temperature, contain equal kinetic energies.
Assuming the kittens on the stairs all have the same mass, which kitten has the most gravitational potential energy? Question 5 options: kitten 1 kitten 2 kitten 3 kitten 4 kitten 5
Answer:
Assuming 5 stands above all of them.
5>4>3>2>1
Explanation:
As gravitational potential energy is the measure of energy in a body due its position from the earth surface so kitten 5 is high from all others so it will have the highest potential energy.
Gravitational Potential Energy = mgh
m=mass
g= constant for all.
h= it is varying in this case.
Let us assume height of kitten 5, 4, 3, as 5m, 4m,3m so on
Gravitational Potential Energy (5) = mg5
Gravitational Potential Energy (4) = mg4
So the kitten which is at the top will have the highest Gravitational potential energy.

Answer:

Explanation:just did on edge
By digging snow tunnels from their shelters to the tunnel.
What is tunnel?When you're gazing straight ahead, your peripheral vision, also known as side vision, is what you perceive on the edges of your visual field.
When this peripheral vision is compromised, tunnel vision results. If this occurs, you won't be able to see anything unless you are directly facing it.
Two different kinds of photoreceptors, or light-sensing cells, in the retina, called rods and cones, are the primary culprits in this kind of vision loss. By identifying light and communicating information to the brain, the retina aids with vision.
A brain injury may also result in tunnel vision. For instance, even if there is no injury to the eye itself, a stroke can harm the brain's visual system and result in tunnel vision.
Therefore, By digging snow tunnels from their shelters to the tunnel.

Answer:
14, 21 and 28
Explanation:
2 : 3 : 4 - find the total of the numbers in the ratio cubed
2³ + 3³ + 4³ = 99 - divide 33957 by the total (99)
33957 ÷ 99 = 343 - cube root 343
∛343 = 7
This means we have to multiply each number in the ratio by 7 to find the answers:
2 × 7 = 14, 3 × 7 = 21, 4 × 7 = 28
Answer: 14, 21, and 28
Check:

Player 1 had a hang time of 0.9 s. Player 2 had a hang time of 0.8 s. To the nearest inch, how much higher did Player 1 jump than Player 2? in.
Answer:
8in
Explanation:
edge 2020
The amount of height that player 1 jumped higher than player 2 to the nearest inch is; 8 inches
How to substitute values into an equationWe are given the hang time equation as;
t = 2(2h/32)^(½)
Where;
h is height of jump
Hang time of player 1 = 0.9 s
Hang time of player 2 = 0.8 s
Let's make h the subject of the hang time equation to get;
h = 2t²
For player 1;
h1 = 2(0.9)²
h1 = 3.24 ft
Converting to inches gives;
h1 = 38.88 inches
For player 2;
h2 = 2(0.8)²
h2 = 2.55 ft
Converting to inches gives
h2 = 30.72 inches
Difference in jump height = h1 - h2
Difference in jump height = 38.88 - 30.72
Difference in jump height ≈ 8 inches
