Answer:
More electronegative
Explanation:
The oxygen and nitrogen in ammonia shows that they are more electronegative than the hydrogen atoms.
- Electronegativity shows the affinity of an atom for valence electrons.
- Electronegativity is the measure of the relative tendency with which the atoms of the element attract valence electrons in a chemical bond.
The oxygen atom in water and the nitrogen atom in ammonia are more electronegative.
They attract the electrons more and they then become negatively charged.
The hydrogen will then become positively charged in the shared covalency.
Answer: Adiabatic process is a process in which <u>heat</u> is constant
Explanation:
The processes in which temperature remains constant is called isothermal process.
The process in which Volume remains constant is called isochoric process.
The process in which pressure remains constant is called isobaric process.
The process in which no heat is gained or lost by the system, Hence heat remains constant is called as adiabatic process.
Thus option d) heat is correct
Answer:
<h3>The answer is 40.96%</h3>
Explanation:
The percentage error of a certain measurement can be found by using the formula
From the question
actual density = 2.49g/mL
error = 2.49 - 1.47 = 1.02
We have
We have the final answer as
<h3>40.96 %</h3>
