Answer:
1. Nonmetal
2. Nonmetal
3. Covalent
Explanation:
Methane is the molecule being described in this question. It has a chemical formula of CH4 where four hydrogen atoms are bonded to one central carbon atom. Carbon as well as hydrogen are non-metallic elements, which means that they can only share their valence electrons to form a COVALENT BOND.
A covalent bond is a type of chemical bond in which two atoms share their valence electrons. It occurs between two non-metallic atoms. In this molecule, CH4, carbon and hydrogen share their valence electrons to form a covalent bond.
Answer:
The answer to your question is Theoretical yield
Explanation:
Theoretical yield is the quantity of a product obtain considering that all the reactants will be converted into products. The theoretical yield considers that the reaction is 100% effective, but this is not true most of the chemical reactions have a yield of 80 % or lower.
Answer:
1. DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals called mutagens, or infection by viruses.
2. both
Explanation: Since errors can occur when DNA replicates itself, mutations can occur in both asexually and sexually reproducing organisms.
Actually, Henry's Law is an empirical value. It means that it was not obtained out of raw calculations or correlations. This was gathered from experimental results. Hence, you can search its data. At standard temperature of 25°C (298 K),
k = k°e^[2400(1/T - 1/T°)], where k° = 29.4 L·atm/mol
Substituting the values so that T would be in 20°C or 293 K,
k = (29.4 L·atm/mol)e^[2400(1/293 - 1/298)]
k = 33.7 L·atm/mol
Answer:
If you were to plug your nose, it would block out more than 80% of taste, causing all three items to have no taste- therefore making them taste the same.
