Answer:
chlorine and salt is the answer if the answer is correct mark me brainliest and if the answer is wrong i will send you 1000 brainly points
Answer:
From least polar covalent to most polar covalent;
S-I< Br-Cl < N-H< Te-O
From most ionic to least ionic
Cs-F> Sr-Cl> Li- N> Al-O
Explanation:
Electro negativity is the ability of an atom in a bonding situation to attract the electron pair of a bond towards itself.
Electro negativity difference between two atoms determines the nature of bond existing between any two atoms. When this difference is large, an ionic bond exists in the compound. However, an intermediate difference in electro negativity implies the existence of a polar covalent bond.
Hence, going by electro negativity differences as mentioned in the question, the bonds in the answer were arranged in order of increasing polar covalent nature or decreasing ionic nature as shown.
Answer:
Explanation:
We assume there is 100g of this first for simplicity. That means, there will be 80g of C, 8.33g of H, and 11.67g of N. Now, we need to find the moles of each:
C = 80/12.01 = 6.66
H = 8.33/1.008 = 8.26
N = 11.67/14.01 = 0.833
Then, we divide each one by the element with the lowest amount of moles which is N.
We get 6.66/0.833 = about 8 (this is for carbon)
We get 8.26/0.833 = about 10 (this is for hydrogen)
We get 0.833/0.833 = 1 (for Nitrogen)
Then we get the empirical formula
Answer:
Decreased kinetic energy of the molecules
Explanation:
Temperature is a measure of the average kinetic energy of the molecules in a substance.
If the temperature decreases, the average kinetic energy of the molecules decreases.
A and C are wrong. Temperature has no effect on the chemical energy of molecules.
