A. loses electron, bc electrons are negatively charged, protons are positively charged, when electrons are lost, that means there are more protons more
The process of uranium mining generates what is called uranium tailings. These are the waste by products of uranium mining. Tailings contain the radioactive decay products of the uranium atom and these products are quite radioactive. Radioactive particles found in tailings can emit anywhere from twenty to one hundred times as much radiation as the natural levels at natural uranium deposits. These radioactive byproducts can lead to cancer if exposed.
Answer:
2.4 dm-3
Explanation:
Equation of the reaction;
2HCl(aq) + Ba(OH)2(aq) -------> BaCl2(aq) + 2 H2O(l)
Volume of acid VA = ??
Concentration of acid CA = 0.25 moldm-3
Volume of base VB = 2.0 dm^3
Concentration of base CB = 0.15 moldm-3
Number of moles of acid NA = 2
Number of moles of base NB = 1
CAVA/CBVB = NA/NB
CAVANB = CBVBNA
VA = CBVBNA/CANB
VA = 0.15 * 2 * 2/0.25 *1
VA = 2.4 dm-3
Answer:
When we stand on the floor, we apply a force on the floor surface in the downward direction and in return the floor also exerts an upward and equal force on us.
Explanation:
Newton' third law is vey famous and it states that for each and every action, there applies an equal but opposite reaction. Thus the action force and the reaction force always acts on pairs. But they does not contribute to the motion of the object.
One such example that illustrates the action and reaction force from Newton's law is when we stand on the floor we exert a force on the floor surface in downward direction. The floor surface also exerts an opposite and equal force on us in the upward direction.
The concentration of a substance is the quantity of solute present in a given quantity of solution.
