Answer:
Yes, it does not have chemical properties.
Explanation:
Helium, as an inert element, cannot rearrange its electrons to form another chemical substances with another element, like a combustion or an acidification, even though it can form nuclear reactions, these are not considered chemical reactions, because it does not involve a rearrangement of the electrons but changes the nucleus of the element giving another elements.
The nuclear force is the force that binds all the particles found inside the nucleus. The nucleus is the very dense part of an atom. It occupies very little space, but the majority of the element's mass resides in the nucleus. Because of the little space, there is a great attractive force between neutrons and protons. That is why nuclear reactions are associated with very high energy reactions because you need to break the nuclear force in order to create a new element.
Answer:
374°F
463.15K
Explanation:
This particular Question wants to test knowledge on the conversion of the units of temperature from celsius degree to degree Fahrenheit. Also, the conversion of degree celsius to kelvin.
The value given which is 190 degree celsius can be converted into degree Fahrenheit using the formula below;
(x°C × 9/5 ) + 32.
Therefore, x = 190°C =( 190°°C × 9/5) + 32 = 374°F.
The conversion of degree celsius to kelvin is given below as;
x°C + 273.15 .
Therefore, x = 190°C = 190°C + 273.15 = 463.15K.
Therefore, the temperature needed to bake at Fahrenheit and kelvin are 374°F and 463.15K respectively.
B) loses electrons and is oxidised
Its oxidation number is 0 in Co(s) and +2 in Co(C2H302)2(aq), hence it gets oxidised
First, use the given amount of reactants to calculate the theoretical amount of products that should be formed based on stoichiometry. Next, divide the actual amount of obtained product by that theoretical amount, and multiply by 100%. This gives the percent yield of the reaction.
