Answer:
if balanced reaction then 2 NaOH + MgSO4 → Mg(OH)2 + Na2SO4
Explanation:
Answer:742 torr= approximately 0.976 atm
Explanation:
Since we know that one atm= 760 torr, we can compute the following calculation:
(742 torr/1)*(1atm/760torr)=0.976316 atm
Remember sig figs (3) to round it to 0.976 atm
*
=0.976316=0.976 atm
(torr cancels out and we're left with atm)
Hope this helps :)
Chemical energy is the energy that bonds atoms are ions together. This energy is released when the chemical bonds are released. Atoms or ions bond together to form molecules or compounds. Breaking the bonds of these molecules release energy. The food we eat contains chemical energy. When oxygen is combined to sugars in food via the process of respiration, the bonds in the sugar molecules are broken and the energy that is released is used to carry out bodily functions. <span />
An element can be represented symbolically in terms of its atomic number and mass number as:
_{Z}^{A}\textrm{X}
where X = symbol of the element
A = atomic mass
Z = atomic number
In this case we have the representation as:
_{0}^{1}\textrm{n}
where n = symbol for neutron
mass number of neutron = 1
charge/atomic number of neutron = 0
Ans: D) A neutron of zero charge and one unit mass
A Hypothesis.
