Answer:
Ionic bonds are formed between metals and nonmetals. The compatability of the metals and nonmetals is what makes them have a neutral charge as they cancel each other.
Eg: Using sodium chloride.
Na+ + Cl- > a neutral compound of NaCl without charges.
Answer:
The correct answer is c. adding a catalyst for the reaction
Explanation:
The function of a catalyst in a chemical reactionis to increase the rate of reaction by decreasing the required activation energy which is clearly illustrated on energy diagrams. It is not consumed in the reaction and can be reused repeatedly,as such, only small quantities of catalysts are required in the reaction. Catalyst provide a separate route for a chemical reaction to proceed at a lower activation energy than an uncatalysed reaction
The process of speeding up a chemicals reaction by the addition of a catalyst is known as catalysis
Answer:
-0.93 °C
Explanation:
Hello,
The freezing-point depression is given by:
Whereas 
is the freezing temperature of the solution, 
is the freezing temperature of the pure solvent (0 °C since it is water), 
the Van't Hoff factor (1 since the solute is covalent), 
the solvent's freezing point depression point constant (in this case 
) and 
the molality of the glucose.
As long as the unknown is , solving for it:
Best regards.
The answer would be letter A.Among the alkali earth metals, the tendency to react with other substances <span>increases from bottom to top within the group. We know that when there is an increase of metallic property, there will also be an increase of reactivity. </span>
