Answer: 14.3%Explanation: In order to find the mass percent of hydrogen in this compound, you must determine how many grams of hydrogen you'd get in 100 g of compound.
In your case, you know that an unknown mass of hydrogen reacts with 0.771 g of carbon to form 0.90 g of hydrocarbon, which is a compound that contains only carbon and hydrogen.
Use the total mass of the hydrocarbon to determine how many grams of hydrogen reacted with the carbon.
Now, if 0.90 g of this compound contain 0.129 g of hydrogen, it follows that 100 g of this compound will contain.
So, if 100 g of this compound contain 14.33 g of hydrogen, it follows that the mass percent of hydrogen is 14.3%

Answer is Halogenation because Halogenation is a type of substitution reaction in which a hydrogen atom is replaced by a halogen atom in a molecule.
The molecule looses its hydrogen atom as the halogen is introduced into the molecule. This sort of reaction is very common in organic chemistry. Many hydrocarbons can be halogenated in the presence of light.
Lead can cause
D.) brain damage
Explanation:
Lead poisoning is a sort of metal poisoning generated by lead in the body. The brain is the most sensitive. Symptoms may comprise abdominal pain, illness, headaches, irritability, thought problems, inability to have children, and tingling in the hands and feet. It causes almost 10% of the intelligent weakness of otherwise unknown cause also can result in behavioral problems. Some of the outcomes are strong. In severe cases, anemia, convulsions, coma, or death may occur.
Metallurgy is the science and technology of metals and alloys. The study of metallurgy can be divided into three general groups: ... Process metallurgy is concerned with the extraction of metals from their ores and the refining of metals.
Answer:
H-BI,H-Se,H-S,H-I,H-Br
Explanation:
One thing that must be kept in mind is that atomic size increases down the group and decreases across the period. The bond lengths of species are influenced by the relative sizes of atoms or ions present in the bond.
The bonds in the answer have been arranged on basis of their decreasing atomic size because the greater the atomic size of the atoms, the greater the bond length and vice versa.
