Li3N
Answers
Answer:
Combination or synthesis
Explanation:
The given reaction is:
6Li + N₂ → 2 Li₃N
This reaction is a synthesis or combination reaction. 6 moles of Li combines with nitrogen gas to produce 2 moles of Li₃N.
In a synthesis reaction, two substances combines together to give singular product. The formation of compounds from the union of the constituent elements falls into this category of reaction.If a 50kg car is pulling a 30kg car, how much force would be required to accelerate the cars at 2m/s/s?
Answers
Answer:
160N
Explanation:
The force required to accelerate the two cars can be calculated thus:
F = m × a
Where;
F = force (Newton)
m = mass (kg)
a = acceleration (m/s²)
However, according to the question, a 50kg car is pulling a 30kg car, which means that the mass of the two cars is 50kg + 30kg = 80kg.
a = 2m/s²
F = ma
F = 80 × 2
F = 160N

Which periodic table trend is represented by the blue arrows?
Answers
Answer:
Periodic trends are specific patterns that are present in the periodic table that illustrate different aspects of a certain element, including its size and its electronic properties. Major periodic trends include: electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic character. Periodic trends, arising from the arrangement of the periodic table, provide chemists with an invaluable tool to quickly predict an element's properties. These trends exist because of the similar atomic structure of the elements within their respective group families or periods, and because of the periodic nature of the elements.
A scientist thinks he found a new metal, so he published a paper about this metal. About 1 week after the scientist published the paper, you noticed a problem with the paper the scientist wrote. You noticed that this metal was not a new metal. In fact, this metal was discovered years ago. You determined this when you saw the atomic emission spectrum. As you read the article, you remembered that each atomic emission spectrum is unique to each element and the atomic emission spectrum matched one that was already discovered. Using the techniques from Chemistry, you ran a Flame Test with a piece of the metal (the metal is safe to use) that you had shipped to you. You found the metal turned the flame yellow. What metal did you have in your possession?

calculate the molar mass of cacl2
Answers
Answer:
[tex]\boxed {\boxed {\sf 110.98 \ g/mol}}[/tex]
Explanation:
The molar mass is the mass of a substance in grams per mole.
To find it, add the mass of each element in the compound. These masses can be found on the Periodic Table.
The compound given is:
[tex]CaCl_2[/tex]
The compound has 1 Ca (calcium) and 2 Cl (chlorine).
Mass of Calcium
The molar mass of calcium is 40.08 g/mol There is only one atom of Calcium in CaCl₂, so the number above is what we will use.Mass of Chlorine
The molar mass of chlorine is 35.45 g/mol There are two atoms of chlorine in CaCl₂, therefore we need to multiply the molar mass by 2. 35.45 * 2= 70.9 g/molMolar Mass of CaCl₂
Now, to find the molar mass, add the molar mass of 1 calcium and 2 chlorine. 40.08 g/mol + 70.9 g/mol =110.98 g/molThe molar mass of CaCl₂ is 110.98 grams per mole.

The sample here is a compound. The correct option is c.
What is a compound?A chemical compound is a substance made up of many identical molecules that contain atoms from more than one chemical element and are held together by chemical bonds.
A molecule made up of only one element's atoms is thus not a compound.
The anode undergoes oxidation, while the cathode undergoes reduction. The species being oxidized provides the electrons.
An electrode in an electrochemical cell is referred to as an anode or a cathode depending on the direction of electron flow.
The electrode reacts with the electrolyte at the anode, producing electrons.
These electrons build up at the anode. Meanwhile, another chemical reaction occurs at the cathode, allowing that electrode to accept electrons.
Thus, the correct option is c.
