Answer:
H+ and NO3- ions
Explanation:
The Pb²+ ions react with the SO4²‐ ions to form a solid precipitate, i.e. they bond together and undergo a phase change;
On the contrary, the H+ and NO3- ions are aqueous ions before the reaction and the same after the reaction, i.e. they don't change;
Hence, the H+ and NO3- ions are spectator ions
The way to do this type of question is to consider what changes and what doesn't, look at phase changes and oxidation state changes
Answer:
organic
Explanation:
Organic substances are those which contains covalently linked carbon to hydrogen (C-H) bonds in their structure. In other words, organic compounds or substances are uniquely composed of carbon and hydrogen atoms covalently linked together.
These substances usually contain a long chain of these bonds, hence, making them complex. Therefore, according to this question, substanves that are complex molecules and contain carbon atoms bonded to hydrogen atoms are referred to as ORGANIC SUBSTANCES.
60mol O2 × 1 mol C6H12O6 / 6 moles 02 = 10 moles of Glucose
Explanation:
38 ATP molecules May be produced from glucose
Answer : The number of electrons shared between 1 nitrogen atom and 1 carbon atom are, Six.
Explanation :
Covalent bond : Covalent bonds are made by the sharing of valence electrons between the non-metal elements.
One covalent bond is formed by the sharing of two electrons.
In the given structure of compound, one nitrogen atom bonded with one carbon atom by three covalent bonds. That means the number of sharing electrons between the one nitrogen atom and one carbon atom are six.
