Answer:
Calculate the volume (in mL) of the 1.356 M stock NaOH solution needed to prepare 250.0 mL ... Glucose (molar mass=180.16 g/mol) is a simple, soluble sugar ... g of glucose in enough water to make 500.0 mL of solution. • Step 2: Transfer 18.6 mL of glucose
a compound is a pure substance made up of two or more elements chemically combined a molecule is defined as the smallest particle of an element which can exist separately elements are pure substances which can not be split into simple substances by chemical means the atom is defined as the smallest particle of an element which can take part in a chemical change so I think the difference between the molecule of a compound is bigger than the molecule of a compound
Nitric acid is HNO3 while Calcium Hydroxide is a base with a chemical formula Ca(OH)2. When acid reacts with base, it forms salt and water (H20). Hence forming the equation HNO3 + Ca(OH)2 -> Ca(NO3)2 + H20.
To gain the same number of atoms on both sides, the balanced molecular equation should be:
2NO3 + Ca(OH)2 -> Ca(NO3)2 + 2H2O
with: 4 Hydrogen, 2 Nitrogen, 8 Oxygen, and 1 Calcium
The answer is false. Hope this helps
Answer:
A. electrons simultaneously attracted by more than one nucleus
Explanation:
- Covalent bond is the bond which is formed with the sharing of the electrons between the two atoms which are taking part in the bond. It is generally formed between the atoms with similar electronegativity values.
- It is the bond which is generally occurs within non metals as they share electrons to complete their octet.
- The difference in the electronegativity values of the atoms involving in a covalent bond must not exceed the value of 1.7 .
Thus, the electrons are attracted by the two different nucleus of the atoms that are taking part in the bonding.
<u>So, the correct answer is:- A. electrons simultaneously attracted by more than one nucleus</u>
