Answer:
0.014 M/s
Explanation:
The rate of a chemical reaction is defined as the change in the concentration of the products or reactants over a specific period of time. The reaction rate can be calculated by dividing the change in concentration of the reactants products by the time elapsed for the given reaction. The reaction rate can also be calculated bu using:
![r = k*[CH_{3}Br]*[NaOH]](https://tex.z-dn.net/?f=r%20%3D%20k%2A%5BCH_%7B3%7DBr%5D%2A%5BNaOH%5D)
where:
r is the rate of the reaction, k is the rate constant, and [] signifies the concentration of the compound.
When the concentrations of 
and NaOH are both 0.140 M, the rate of the reaction is 0.0070 M/s.
Therefore, when the concentration of is doubled, the rate of the reaction will also be doubled, i.e. r = 2* 0.0070 = 0.014 M/s
Answer:
⁹⁶₄₂Mo + ²₁H ⇒ ⁹⁸₄₃Tc
Explanation:
During the bombardment of a molybdenum target with deuterium ions, an element not found in nature was produced.The name of the element formed in the process is technetium. It is an element with the symbol Tc, mass number of 98, and atomic number 43. The nuclear equation is shown below:
⁹⁶₄₂Mo + ²₁H ⇒ ⁹⁸₄₃Tc
Technetium is the lightest element whose isotopes are all radioactive in nature except the fully ionized state of isotope ⁹⁷Tc. It is silvery gray in color and can be found between manganese and rhenium in group seven of the periodic table.

Answer:
The dots were not properly located and arrows are not used in Lewis structures
Explanation:
If we intend to write a Lewis structure for a compound, that lewis structure must consist of only dots. These dots actually show the valence electrons on the outermost shell of the molecule.
We do not involve arrows when writing dot electron structures for compounds. The valence electrons of magnesium ought not to be written together because they are not a lone pair, rather they are two unpaired electrons. The use of an arrow suggests a coordinate covalent bond which is not the case here.
The correct lewis structure for MgCl2 is shown in the image attached to this answer.
The answer is caves.. i think
