5 0

Answer:

the alkaline earths possess many of the characteristics properties of metals.Alkaline earths have low electron affinities and low electronegativities. As with the alkali metals, the properties depend on the ease with which electrons are lost. The alkaline earths have two electrons in the outer shell. They have smaller atomic radii than the alkali metals. The two valence electrons are not tightly bound to the nucleus, so the alkaline earths readily lose the electron to form divalent cations.

Energy that is not utilized for work or heat transfer is converted to the chemical energy of body fat containing about 39 kJ/g.
AnnZ [28]

Answer:

m=107.8g

Explanation:

Hello,

In this case, for the given information, we can compute the gained grams by firstly compute the energy consumed by 14.3 h of being sit relaxed and 9.70 h  of sleeping:

E_{sit}=120\frac{J}{s}*\frac{3600s}{1h}  *14.3h*\frac{1kJ}{1000J} =6177.6kJ\\\\E_{sleep}=83\frac{J}{s}*\frac{3600s}{1h}  *9.70h*\frac{1kJ}{1000J} =2898.36kJ

Then, we compute the energy used that day:

E_T=10000kJ-2898.36kJ-6177.6kJ=4203.28kJ

Finally, the mass by considering the consumed fat:

m=\frac{4203.28kJ}{39kJ/g} \\\\m=107.8g

Regards.
