Answer: Major scale and minor scale both relate the precision of measurements with more true value of measurement.

Explanation:

Major scale in a measuring device is maximum unit value on the scale that can be measured.

Minor scale in a measuring device is a least unit value on the scale that can be measured.

In a metric ruler major scale is 1 cm and minor scale is 0.1 mm which means one can measure accurate value up-to one decimal point and in 10 ml of graduated cylinder major scale division is 1 ml minor scale division is 0.01.

If a bus traveled 20 miles north on a straight path, and then traveled 20 miles back to the starting point, what would the veloc

AleksAgata [21]

Answer:

The velocity of the bus be is 0 miles/second

Explanation:

Given, a bus travelled a distance of 20 miles north and 20 miles back to the starting point

Hence, total distance = 20 + 20 = 40 miles

Velocity is calculated by the formula:

Velocity = $\frac{\text { Displacement }}{\text { Time }}$

Displacement = $20+(-20)=0 \text { miles }$

Velocity = $\frac{0}{T i m e}=0 \text { miles/second }$

Therefore, the velocity of the bus is 0 miles/second

Why is it easier to pull a valence electron from a larger metal atom?

s2008m [1.1K]

The larger it is, the farther away the valence electrons is from the nucleus. This means that the pull is weaker, making it easier to pull the valence electrons away.

An aqueous solution of sodium sulfide is allowed to react with an aqueous solution of magnesium chloride.The complete ionic equa

dimulka [17.4K]

Answer: The complete ionic equation contains $2Na^{+}(aq.)$ ions

Explanation:

Complete ionic equation is defined as the equation in which all the substance that are strong electrolyte are present in an aqueous are represented in the form of ions.

The chemical equation for the reaction of sodium sulfide and magnesium chloride is given as:

$Na_2S(aq.)+MgCl_2(aq.)\rightarrow 2NaCl(aq.)+MgS(s)$

Ionic form of the above equation follows:

$2Na^{+}(aq.)+S^{2-}(aq.)+Mg^{2+}(aq.)+2Cl^{-}(aq.)\rightarrow MgS(s)+2Na^+(aq.)+2Cl^-(aq.)$

The complete ionic equation for the above reaction follows:

$2Na^{+}(aq.)+S^{2-}(aq.)+Mg^{2+}(aq.)+2Cl^{-}(aq.)\rightarrow MgS(s)+2Na^+(aq.)+2Cl^-(aq.)$

Hence, the complete ionic equation contains $2Na^{+}(aq.)$ ions
