What are the different types of constant in C? There are 4 types of constants in C. Integer constants. Character constants. Real/Floating point constants. String constants. What is constant in C language with example? A constant is a value or variable that can’t be changed in the program, for example: 10, 20, ‘a’, 3.4, “c […]
What is the basic principle of mass spectrometry?
What is the basic principle of mass spectrometry? “The basic principle of mass spectrometry (MS) is to generate ions from either inorganic or organic compounds by any suitable method, to separate these ions by their mass-to-charge ratio (m/z) and to detect them qualitatively and quantitatively by their respective m/z and abundance. What does M Z […]
What is the best definition of physical science?
What is the best definition of physical science? Physical science is the study of the inorganic world. That is, it does not study living things. (Those are studied in biological, or life, science.) The four main branches of physical science are astronomy, physics, chemistry, and the Earth sciences, which include meteorology and geology. What are […]
Does magnesium or phosphorus have a larger atomic radius?
Does magnesium or phosphorus have a larger atomic radius? Atomic radius Element Symbol Atomic radius /nm magnesium Mg 0.160 aluminium Al 0.130 silicon Si 0.118 phosphorus P 0.110 Which has bigger atomic radius magnesium or chlorine? Since chlorine’s 17 protons are greater than magnesium’s 12 protons, chlorine will have a greater effective nuclear charge to […]

Why do covalent compounds have low melting and boiling point?
Why do covalent compounds have low melting and boiling point? Covalent bonds are very stable and the interatomic forces are quite strong. But, the intermolecular forces between covalent compounds are weak. Since lower heat (energy) is capable of breaking these weak intermolecular forces, therefore the melting and boiling points of covalent compounds is low. Why […]
How did militarism threaten the peace in early 20th century in Europe?
How did militarism threaten the peace in early 20th century in Europe? How did militarism threaten the peace in early 20th-century Europe? Competition for larger navies caused an arms race between major countries. Alliances between minor countries resulted in rivalries with major countries. AlliMembers of ethnic groups attempted to unite territories under one national government. […]
What was the main goal of the Human Genome Project?
What was the main goal of the Human Genome Project? One goal of the project was to accurately sequence the 3 billion nucleotide base pairs in the human genome. A second goal was to map and identify all of the human genes present in the DNA sequence. (The number of genes is currently estimated to […]
What are the patterns of population growth?
What are the patterns of population growth? Two types of population growth patterns may occur depending on specific environmental conditions: An exponential growth pattern (J curve) occurs in an ideal, unlimited environment. A logistic growth pattern (S curve) occurs when environmental pressures slow the rate of growth. What are the two factors that affect the […]
What is a rule for making a positive ion which has positive charge?
What is a rule for making a positive ion which has positive charge? Protons are identical in the atom and ion. Positive charge is caused by lack of electrons. A positive ion is formed by the loss of negatively charged electrons. Although the number of protons does not change in the ion, there is an […]
