Answer:
Sour and Possible Burns
Explanation:
Bases are soapy, not acids.
All acids are sour to taste.
Neither bases nor acids are sweet.
Sharp is a physical trait for things such as knives, not acidic liquids.
Acids can cause burns if handled incorrectly.
Answer:
Explanation:
The balanced chemical reaction equation is;
2AgNO3(aq) + Cu(s) -> 2Ag(s) + Cu(NO3)2(aq)
When we balance chemical reaction equations, we ensure that the number of atoms of each element on the left hand side of the reaction equation is exactly the same number of atoms of each element on the right hand side of the reaction equation.
Let us consider this reaction;
There are two atoms of Ag on both sides of the reaction equation
There are six atoms of O on both sides of the reaction equation
There are 2 atoms of N on both sides of the reaction equation
There is one atom of Cu on both sides of the reaction equation.
Hence, the reaction equation is balanced.
Answer:
![\Delta G=-44.9kJ](https://tex.z-dn.net/?f=%5CDelta%20G%3D-44.9kJ)
Explanation:
We know, ![\Delta G=\Delta G^{0}+RTlnQ](https://tex.z-dn.net/?f=%5CDelta%20G%3D%5CDelta%20G%5E%7B0%7D%2BRTlnQ)
where Q is the reaction quotient and for this reaction, it is expressed as-
where species under third bracket represent concentrations in molarity.
T represents temperature in kelvin scale
Here T = 298 K
R = gas constant = 8.314 J/K
So, ![\Delta G=(-48.1\times 10^{3}J)+(8.314\frac{J}{K}\times 298K)ln(\frac{1}{0.312\times 0.898})](https://tex.z-dn.net/?f=%5CDelta%20G%3D%28-48.1%5Ctimes%2010%5E%7B3%7DJ%29%2B%288.314%5Cfrac%7BJ%7D%7BK%7D%5Ctimes%20298K%29ln%28%5Cfrac%7B1%7D%7B0.312%5Ctimes%200.898%7D%29)
or, ![\Delta G=-44948J](https://tex.z-dn.net/?f=%5CDelta%20G%3D-44948J)
or, ![\Delta G=-44.9kJ](https://tex.z-dn.net/?f=%5CDelta%20G%3D-44.9kJ)
<u>Answer:</u> The group of elements that corresponds to the electronic configuration
is group 13.
<u>Explanation:</u>
Electronic configuration is defined as the representation of electrons in a given atom.
Valence electrons are defined as the electrons present in the outermost shell or the sub-shell having highest value of 'n'.
We are given:
General electronic configuration =
where,
n = principal quantum number and is determines the energy level of the sub-shell
The number of valence electrons in the configuration are = 2 + 1 = 3
And, as the last electron is entering the p-subshell, so the element is a p-block element.
The given electronic configuration is of group 13 elements.
Hence, the group of elements that corresponds to the electronic configuration
is group 13.
