Bed frame is metal so it is able to be sturdy and hold up
cleaning agents are mettaliods some contain boron to control strength of bleach , and removing stains
plotting soil is non metal it is rich with nitrogen which is good for plants
Answer:
1. The correct option is;
c. maintains charge balance in the cell
2. The correct option is;
c. +3.272 V
Explanation:
The aqueous solution in a galvanic cell is the electrolyte which is a ionic solution containing that permits the transfer of ions between the separated compartment of the galvanic cell such that the overall system is electrically neutral
Therefore, the aqueous solution maintains the charge balance in the cell
2. Here we have;
B₂ + 2e⁻ → 2B⁻ Ecell = 0.662 V
A⁺ + 1e⁻ → A Ecell = -1.305 V
Hence for the overall reaction, we have;
2A + B₂ → 2AB gives;
(0.662) - 2×(-1.305) = +3.272 V.
Answer:
<em>lithosphere</em><em> </em><em>(land)</em>
<em>hydrosphere (water)</em>
<em>biosphere</em><em> </em><em>(living things)</em>
<em>atmosphere (air).</em>
The correct answer is a mass of products = mass of reactants.
In a chemical reaction, the law of conservation of mass states that the entire mass of reactants is equivalent to the entire mass of products. For example, the mass of sodium and the mass of chlorine, which reacts with the sodium is equivalent to the product sodium chloride's mass. As in the chemical reaction, the atoms are only rearranged, there must be an equal number of chlorine and sodium atoms in both the products and the reactants.
Answer:
T_2=338.9026K
Boiling point of CH3COOCH3 at external pressure is 338.9026K
Explanation:
We are going to use Clausius-Clapeyron Equation:
Where:
P_2 is the external pressure
P_1 is the atmospheric Pressure=1 atm
ΔH is the heat of vaporization
T_2 boiling point of CH3COOCH3 at external pressure
T_1 normal boiling point of liquid methyl acetate
Now:
Boiling point of CH3COOCH3 at external pressure is 338.9026K
