Answer:
<em><u>Mass (kg) × Acceleration (m/s²) = Force (N)</u></em>
D.
A more accurate answer would be -50 m/s. 50 m/s is the change in speed.
The chemical reaction would be written as:
2HgO = 2Hg + O2
We use this reaction and the amount of the reactant to calculate for the moles of oxygen produced. THen, we use avogadro's number to convert it to molecules. We do as follows:
12.5 g HgO (1 mol / 216.59 g) (1 mol O2 / 2 mol HgO) ( 6.022x10^23 molecules O2 / 1 mol O2 ) = 1.74x10^22 molecules O2 produced
You can develop acute radiation syndrome or skin cancer.
Answer: Electrons
Explanation:
Most of an atoms' mass comes from the protons and neutrons that make up its nucleus. Electrons have the least mass of an atom's particles.
