Answer:- 
for the reaction is -58 kJ/mol.
Solution:- Oxidation half reaction taking place at the anode is--
= 0.14 V
Reduction half equation taking place at the cathode is---
= -0.04V
for the cell = 
for the cell = -0.04V + 0.14V = 0.10V
Now we could easily calculate by using the below formula--
= -nF
where n is the number of electrons transferred in the over all reaction. Looking at two half equations the value of n is 6.
F is Farady constant and it's value is 96500 C/mol.
Plugging in the values in the formula...
= -(6)(96500)(0.10)
= -57900 J
Since, 1000 J = 1 kJ
So, = -58 kJ/mol
Comets are icy bodies because they originate in areas beyond Neptune.
Option a
<u>Explanation:</u>
Comets are icy, “small solar system” bodies that, warms up and begins to release gases or dust when it passes close to the Sun. The nucleus of a comet is made up of an combination of rock, dust, water ice, and frozen carbon dioxide, carbon monoxide, methane, and ammonia while the surface of the nucleus is generally dry, dusty or rocky.
They are often called as dirty snowballs because of their physical appearance and due to the fact that these Short-period comets originate in the Kuiper belt that lies beyond the orbit of Neptune. Comets have an icy body because they originate from a disk-shaped band of icy objects known as the “Kuiper Belt” that lies just “beyond Neptune's orbit”, with gravitational interactions with the outer planets dragging these bodies inward.
Answer:
the chemical change occur in burning paper.
boiling water does not make any chemical change
melting gold "
dissolving sugar in water "
in these examples the reactant remains as the same , even if you melt gold it is gold itself, it only change its state.
Answer:
The Civil Rights Act of 1964 prohibits discrimination on the basis of race, color, religion, sex or national origin. ... The Act prohibited discrimination in public accommodations and federally funded programs. It also strengthened the enforcement of voting rights and the desegregation of schools.
Answer:
Bromobenzoic acid
Explanation:
COOH has higher priority than Br, so the parent name is benzoic acid.
The COOH group is automatically on C1 of the ring, and the other aromatic carbons are numbered sequentially around the ring.
The name of the substituent is joined to that of the parent, and the locant is attached to that with a hyphen.
The generic IUPAC name is bromobenzoic acid.
There are three isomers of benzoic acid — 2-bromobenzoic acid, 3-bromobenzoic acid, and 4-bromobenzoic acid — so you must always specify which one you mean.
