They move freely and combine with each other.
The final temperature on increasing the pressure to 7.65 atm is 637 K.
Explanation:
The relation between temperature attained by gas molecules at varying pressure is defined by Guy-Lusac's law. It states that at constant volume, the pressure experienced by the gas molecules is directly proportional to the temperature attained by those molecules.
P∝T
Here, the initial pressure P₁ is given as 4 atm at temperature T₁ = 333 K, then the final pressure P₂ = 7.65 atm can be attained at temperature T₂.
The final temperature should be greater than the initial temperature as there is an increase in the pressure.
So,
Hence, the final temperature on increasing the pressure to 7.65 atm is 637 K.
Answer:
The correct option is;
c. the bone contains calcium salts, which are less reactive than the calcium ions found in the blood.
Explanation:
The most abundant metallic element found in the human body is calcium as it is present in the bones teeth and metabolism of the kidney
99 % of the calcium in the human body are found in the bones while the remaining 1 % circulates in the blood as ions
The bones of the vertebrate are made up of calcium salts such as calcium carbonate, calcium phosphate and calcium fluoride.
A,
ionic compounds are with a metal and a non metal. A is a hydrocarbon which uses covalent bonds as all the elements involved are non-metals
Answer:
Alkyne are hydrocarbons which contain carbon-carbon triple bonds.
