Arrhenius model considers a base a compound that produces OH(-)
H2SO4 produces H(+) and is an acid
C6H12O6 is an organic product, sugar, that does not produce OH(-)
HOClO2 = HClO3, which produces H(+) and is an acid
NH3 is believed to ionize in water and produce NH4(+) and OH(-).
As per this the answer is NH3.
Nevertheless, NH3 is not a good example of bases as per Arrhenius model, because it is not so evident that NH3 produces OH(-).
Answer: b
Explanation: alpha decay or particle consist of two protons and two neutrons hence it is a helium nucleus.
Answer:
Decomposition
Explanation:
One reactant has formed two products
Answer:
Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.
Explanation:
It goes with velocity
Answer:
Samira's model correctly demonstrates how the properties changed with the rearrangement of the atoms. However not all atoms are accounted for. There is a missing reactant.
Explanation:
Samira's model correctly demonstrated how the atoms in two compounds reacted to form two new products. However, the elements present in the reactants side should be the elements that make up the new products in the product side. But as the diagram shows, Sameera has mistakenly added a new element to one of her products which will be wrong.
