Explanation:
A teacher performs a flame test lab experiment for various compounds. During the lab, the teacher mislabels one of the solutions. She needs to identify the unknown sample. Explain how the teacher can identify the unknown sample.
Answer: By performing the flame test
Explanation:
The flame test can be performed by the teacher to visually identify the substance in the solution. The metals give a characteristic color on burning. The heat of the flame causes the excitation of the electrons present in the metal ions this leads to release of energy along with the emission of visible wavelength of light. This visible light can be observed by human eye. For example, the copper produces the blue color in flame, barium gives green flame, and sodium gives yellow flame.

Write a balanced equation for the following reaction;
potassium metal reacts with nitrogen gas to form potassium nitride
Answer:
6K + N₂ —> 2K₃N
Explanation:
K + N₂ —> K₃N
The above equation can be balanced as illustrated below:
K + N₂ —> K₃N
There are 2 atoms of N on the left side and 1 atom on the right side. It can be balance by putting 2 in front of K₃N as shown below:
K + N₂ —> 2K₃N
There are 6 atoms of K on the right side and 1 atom on the left side. It can be balance by putting 6 in front of K as shown below:
6K + N₂ —> 2K₃N
Now the equation is balanced.

Josh is washing glasses with soap and water. He is afraid to carry the glasses because they are slippery. Josh could dry them with a towel to keep the glasses from being slippery.
What are glasses ?Glasses are visual eyewear that have lenses fixed in a frame that holds them in front of a person's eyes. The frame often has a bridge over the nose and arms that rest over the ears. Glasses are also known as eyeglasses or spectacles.
The term "glasses" likely originated from the word "spyglass," which was originally used to describe "a pair of eyeglasses" that had to be held up to the eyes in order to be fully effective.
Eyeglasses, often known as glasses or spectacles, are lenses that are mounted in frames and worn in front of the eyes to improve vision or to correct astigmatism, myopia, or hyperopia.
Thus, Josh could dry them with a towel to keep the glasses from being slippery.

When Earth is tilted on its axis why does it orbit the sun ?
Answer:
Here
Explanation:
Some assume our planet's changing distance from the sun causes the change in the seasons. That's logical, but not the case for Earth. Instead, Earth has seasons because our planet's axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane, that is, the plane of Earth's orbit around the sun

6. Classify each compound as ionic or molecular based on its properties.
Substance Melting Point Solubility Conductivity Classification
1 -55 oC poor poor
2 396 oC good good
3 0 oC not tested poor
4 200 oC good good
5 20 oC good poor
Answer:
1. c
2. ionic
3. c
4. ionic
5. alloy or ionic
Explanation:
The compound classification.
The compounds are classified as per several different criteria and one common elements is the specific element that is present this makes it an iconic or a molecular. The presence of the oxides, hydrides, and various atomic groups.
Hence the answer is melting point to conductivity classified as c, iconic, c, iconic, and alloy.
A poor conductor of electricity will have a conductivity classification of c. The 396 good conductors will be iconic and a 0 C not teste will have a conductivity of c. The 200 C of good conductor will be iconic and 20 C of good conductor will be alloy or iconic.Learn more about each compound as.

Rahul was given iron filings and sulphur powder. He prepared a compound of iron sulphide by heating the components in a china dish. What would be his observation if he adds a few drops of dilute sulphuric acid into the compound?
Answer:
A gas with a rotten egg smell is evolved
Explanation:
When iron fillings and sulphur were heated in the vessel, the following chemical reaction took place;
Fe(s) + S(s) -----> FeS(s)
This is a direct combination reaction.
Subsequently, when dilute H2SO4 is added, the following reaction takes place;
FeS(s) + H2SO4(aq) ------> FeSO4(aq) + H2S(g)
He immediately observes the evolution of a gas with a rotten egg smell.
