Answer:
Paper is Not Reuseable like plastic.
Explanation:
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.
Answer : Both solutions contain molecules.
Explanation : The number of molecules of 0.5 M of sucrose is equal to the number of molecules in 0.5 M of glucose. Both solutions contain molecules.
Avogadro's Number is = which represents particles per mole and particles may be typically molecules, atoms, ions, electrons, etc.
Here, only molarity values are given; where molarity is a measurement of concentration in terms of moles of the solute per liter of solvent.
Since each substance has the same concentration, 0.5 M, each will have the same number of molecules present per liter of solution.
Addition of molar mass for individual substance is not needed. As if both are considered in 1 Liter they would have same moles which is 0.5.
We can calculate the number of molecules for each;
Number of molecules = ;
∴ Number of molecules = which will be =
Thus, these solutions compare to each other in that they have not only the same concentration, but they will have the same number of solvated sugar molecules. But the mass of glucose dissolved will be less than the mass of sucrose.
Answer:because the chemical formula is vital to the equation it tells you what creates the chemical and whats in it you can change the exponents but not the formula itself
Explanation:
Answer:
The Mouse population will increase: True
The Grass population will increase: False
The Hawk Population will increase: False
The Mouse population will decrease: False
Explanation: This is true because now there is no snake to kill them off. Still, there is the hawk that is there but there will be a general increase in the mouse population
