The density of crystal is 2.65 g / mL
we know that
Density = Mass / Volume
So volume occupied = Mass / density
Mass of crystal = 4.46 g
So volume occupied by crystal = 4.46 / 2.65 = 1.68 mL
As the graduated cylinder contains water upto 25.0 mL
So if we immerse the crystal in that cylinder the water level will rise to 25+1.68 = 26.68mL
so the new read will be 26. 68 mL
Explanation:
A pH helps us to determine whether a solution is basic or acidic in nature.
If pH is less than 7 then the substance or solution is acidic in nature and if pH is more than 7 then the substance or solution is basic in nature.
Also, acids are sour in taste whereas bases are bitter.
Thus, we can conclude that the bottle whose label have fallen off contains an acid and the pH of this liquid is MOST likely less than 7.

Explanation:</h3>
Nickel is the transitional metal in the compound
The overall charge of the compound Ni₃P
= the sum of the charges of element × the number number of atoms
<em />
<em>Because Ni₃P is a neutral compound, then the overall charge of the compound is zero.</em>
⇒ 3 (charge of Ni) + (charge of P) = 0
⇒ 3 (charge of Ni) = - (charge of P) <em> [Redox Rules: Group 15 </em>
<em> elements of -3.]</em>
⇒ 3 (charge of Ni) = - (-3)
(charge of Ni) = + 1
Answer: The rate of the reaction decrease over time as the reaction proceeds, a decrease in the concentration of reactants results in fewer successful collisions.
Explanation:
Rate of a reaction is defined as the change in concentration of products and reactants with respect to time.
The rate of a reaction decreases with times because reactants are converting into products.
As a result, the reaction is proceeding with a decrease in the concentration of reactants due to which less number of collisions between the reactant molecules will be there.
Hence, rate of reaction will decrease.
Thus, we can conclude that the rate of the reaction decrease over time as the reaction proceeds, a decrease in the concentration of reactants results in fewer successful collisions.
