Which variable increases when potential energy increases?

beks73 [17]

Answer:

Height and mass

Explanation:

The potential energy of a body is the energy due to the position of a body.

It is mathematically expressed as:

Potential energy = m g h

m is the mass of the body

g is the acceleration due to gravity

h is the height of the body

Acceleration due to gravity on the earth surface is a constant.

As mass and height of a body increases, the acceleration due to gravity will also increase.

Classify the following as acid-Base reactions or oxidation-reduction reactions:

postnew [5]

Explanation:

(a) $Na_2S+HCl\rightarrow H_2S+2NaCl$

This is acid base reaction because there is no change of oxidation state on either side of the reaction.

(b) $2Na+2HCl\rightarrow H_2+2NaCl$

This is a oxidation reduction reaction because sodium in elemental state ( 0 oxidation state) oxidizes to Na⁺ in NaCl. Also H⁺ in HCl reduces to H° in H₂.

This is a oxidation reduction reaction because magnesium in elemental state ( 0 oxidation state) oxidizes to Mg²⁺ in MgCl₂. Also Cl° in Cl₂ reduces to Cl⁻ in MgCl₂.

(d) $MgO+2HCl\rightarrow H_2O+MgCl_2$

This is acid base reaction because there is no change of oxidation state on either side of the reaction.

(e) $K_3P+2O_2\rightarrow K_3PO_4$

This is a oxidation reduction reaction because phosphorous in P³⁻ in K₃P oxidizes to P⁵⁺ in K₃PO₄ and oxygen reduces.

(f) $3KOH+H_3PO_4\rightarrow K_3PO_4 + 3H_2O$

This is acid base reaction because there is no change of oxidation state on either side of the reaction.
