Answer:

i believe the answer is Aluminum (Al)

Explanation:

Each element has an equal amount of protons to electron so i you subtract one of either you will have to subtract from the other to make sure it is stable. aluminum has 13 protons and electrons. Subtracting 3 from it would gkve it the same qualities as Neon.

The rate constants of some reactions double with every 10-degree rise in temperature. Assume that a reaction takes place at 295
LUCKY_DIMON [66]

Answer : The activation energy for the reaction is, 51.9 kJ

Explanation :

According to the Arrhenius equation,

K=A\times e^{\frac{-Ea}{RT}}

or,

\log (\frac{K_2}{K_1})=\frac{Ea}{2.303\times R}[\frac{1}{T_1}-\frac{1}{T_2}]

where,

K_1 = rate constant at 295 K

K_2 = rate constant at 305 K = 2K_1

Ea = activation energy for the reaction = ?

R = gas constant = 8.314 J/mole.K

T_1 = initial temperature = 295 K

T_2 = final temperature = 305 K

Now put all the given values in this formula, we get:

\log (\frac{2K_1}{K_1})=\frac{Ea}{2.303\times 8.314J/mole.K}[\frac{1}{295K}-\frac{1}{305K}]

Ea=51879.96J=51.9kJ

Therefore, the activation energy for the reaction is, 51.9 kJ

________ investigations allow for the control of variables
zlopas [31]

An experimental investigation allows you to control the variables.

Explanation:

Experimental investigations include a method in which a "fair test" is created and variables are actively planned, managed, and measured in an attempt to gather testimony to confirm or negate a causal relationship. Experimental investigations have a control group which does not accept any treatment.
