Four molecules have carbon as the central atom and hydrogen atoms around it. The shape that would give rise to a polar molecule is a bent shape. <span>The bent shape will not be symmetrical which will result to being polar. Hope this answers the question.</span>

Katena32 [7]

Answer : The distance between the two atoms is $1.2\times 10^{-10}m$

Explanation :

The The formula used for moment of inertia for one atom is:

$I=(\frac{m}{2})r^2$

The formula used for moment of inertia for two atom is:

$I=2(\frac{m}{2})r^2$

where,

I = moment inertia = $1.9\times 10^{-46}kg.m^2$

r = distance of atom from axis of rotation

m = mass of atom = $5.3\times 10^{-26}kg$

Now put all the given values in the above formula, we get:

$I=2(\frac{m}{2})r^2$

$1.9\times 10^{-46}kg.m^2=2(\frac{5.3\times 10^{-26}kg}{2})r^2$

$r=6.0\times 10^{-11}m$

Now we have to calculate the distance between the two atoms.

Formula used :

$d=2r$

where,

d = distance between the two atoms

$d=2\times 6.0\times 10^{-11}m=1.2\times 10^{-10}m$

Therefore, the distance between the two atoms is $1.2\times 10^{-10}m$

Answer:

Granite

Explanation:

The specific heat capacity of a substance, which is denoted by "c", is the amount of heat required to raise the temperature of a particular mass of that substance by 1°C. It is calculated as follows:

c = Q ÷ m∆T

Where;

c = specific heat capacity

Q = amount of heat (J)

m = mass of substance

∆T = change in temperature.

According to this equation and explanation above, a low specific heat capacity means that the rate at which the temperature is raised is slow and vice versa. Hence, from this question, GRANITE with specific capacity of 0.790 J/gK will raise temperature the slowest.

Mandarinka [93]

Answer:

Adhesive forces and cohesive forces

Explanation:

Cohesive forces is how much the water molecules stick to each other and adhesive forces are to which extinct they stick to other surfaces.

When we pull the paperclip upward the water molecules adhere to it due to adhesive forces. While the water on the clip is remain connected to water in the glass because of cohesive forces.

So if the adhesive forces dominates the water will be pulled out and if the cohesive forces dominate it will remain with other water in the cup.
