Answer:

The correct answer is gravity,

Explanation:

Once the object leaves the atmosphere, it is placed in a certain position and begins to orbit the earth. At this point, the possibility of the object remaining in orbit due to gravity will be determined.

Gravity is the force of attraction that exerts all mass on another, and the more mass it has, the greater it will be.

That is why satellites are continuously attracted to the earth.

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.
