Delicious77 [7]

Answer:

East

Explanation:

Given Newton's third law of motion; "Action and reaction are equal and opposite", when a student jumps off a sled toward the west after it stops at the bottom of an icy hill, the sled will move in the East direction.

This is because, the force exerted on the sled is a reaction force and is opposite in direction to the force that thrusts the boy westward though equal in magnitude with the former.

The addition of 250.0 J to 30.0 g of copper initially at 22.0°C will change its temperature to what final value? (Specific heat

WINSTONCH [101]

Answer:

Final temperature = $43.53^{\circ} C$

Explanation:

Given that,

Heat added, Q = 250 J

Mass, m = 30 g

Initial temperature, T₁ = 22°C

The Specific heat of Cu= 0.387 J/g °C

We know that, heat added due to the change in temperature is given by :

$Q=mc\Delta T\\\\Q=mc(T_2-T_1)\\\\\dfrac{Q}{mc}=(T_2-T_1)\\\\T_2=\dfrac{Q}{mc}+T_1$

Put all the values,

$T_2=\dfrac{250}{30\times 0.387}+22\\\\=43.53^{\circ} C$

So, the final temperature is equal to $43.53^{\circ} C$ .

A metal X loses 2 electrons and a non-metal Y gains 1 electron. Show the electron dot structure of compound formed between them.

Stells [14]

Answer:

The compound is ionic

The compound has a high melting point

The compound will conduct electricity in aqueous solution

The compound will be soluble in water

Explanation:

Now, let us consider the nature of the compound formed when a metal X looses two electrons and a non metal Y accepts one electron.

The compound formed must be ionic in nature with a formula XY2. Ionic compounds are formed by transfer of electrons from metals to nonmetals.

The ionic substance formed is always soluble in water with a high melting point. Usually, ionic solids do not conduct electricity in the solid state because the charge carriers (ions) are tightly bound in the crystal structure while in the solid state. In aqueous solution, the ions are relatively free hence ionic substances conduct electricity in aqueous solution.
