Infer if the mineral Talc would be a good choice when building a statue outside. Justify your answer with your knowledge of mine

rals and acid/bases. According to your data, would there be a better mineral to use? If so, which one and why?

Talc is not a good choice when building a statue because Talc is one of the weakest minerals with a hardness of 1 on the Mohs Scale since it could be scratched by a fingernail, which means that when people build a statue with Talc, it could be easily broken down. There would be a better mineral to use, which could be marble because it could last longer than sandstone and is a lot more sturdier than Talc. Marble also could withstand the test of time better than some of the other minerals.

What is the electron configuration of a noble gas?
Debora [2.8K]

Answer:

A noble gas configuration of an atom consists of the elemental symbol of the last noble gas prior to that atom, followed by the configuration of the remaining electrons. So for sodium, we make the substitution of [Ne] for the 1s22s22p6 part of the configuration. Sodium's noble gas configuration becomes [Ne]3s1. That is the answer.

The half-life of the radioisotope 158Eu is 0.77 h. How much time is required for a 160.0-g sample of 158Eu to decay to 2.07 g?
Grace [21]

Answer: e. 4.8 h

Explanation:

Expression for rate law for first order kinetics is given by:

t=\frac{2.303}{k}\log\frac{a}{a-x}

where,

k = rate constant  

t = age of sample

a = let initial amount of the reactant  

a - x = amount left after decay process  

a) for rate constant

Half life is the amount of time taken by a radioactive material to decay to half of its original value.

t_{\frac{1}{2}}=\frac{0.693}{k}

k=\frac{0.693}{0.77hr}=0.9hr^{-1}

b) for 160.0 g to decay to 2.07 g

t=\frac{2.303}{0.9}\log\frac{160.0}{2.07}

t=4.8hr

The time  required for a 160.0-g sample of 158Eu to decay to 2.07 g is 4.8 hours
