Explanation: bc its less then NaOh
Answer:
B)As you go from left to right, reactivity of metals increases. As you go down in a group, reactivity of metals decreases.
Explanation:
reactivity of metals can be explained as how it can easily lose electron, i.e oxidize as well as reaction with non-metals.
There are factors that influence the reactivity of metals such as
1)atomic radius
2)nuclear charge
3)shielding effect
4) The sublevel arrangement of electrons
In the periodic table,the group 1, known as alkali metals, are the most reactive metals
Therefore, as we from left to right, reactivity of metals increases. As we move down in a group, reactivity of metals decreases.

Answer:
answer is in exaplation
Explanation:
Answer. Chemical reaction had occurred and both the powders are different substances.
Explanation:
As density is an intensive property of the substance.Which means that different substance have different densities.
Density = \frac{mass}{volume}
volume
mass
Density of powder 1, d_1=\frac{0.5g}{45cm^3}=0.11g/cm^3d
1
=
45cm
3
0.5g
=0.11g/cm
3
Density of powder 2, d_2=\frac{1.3g}{65cm^3}=0.02g/cm^3d
2
=
65cm
3
1.3g
=0.02g/cm
3
On comparing both the densities of the powders we can say that both the substances are different. So we can conclude that the chemical reaction had occurred.
