Tisa makes a diagram to organize her notes about charging objects.
Amanda [17]
The answer is Electrons move between objects. The reason this is known is that the acts of friction and conduction (from the little picture he could not put in) involves contact to be known as friction and conduction. Without contact the electrons could not move between objects. I also got this question right on the test. That's how I know this is right. I hope this helps. ( ͡° ͜ʖ ͡°)

11mg of cyanide per kilogram of body weight is lethal for 50% of domestic chickens. How many grams per kilogram of body weight i
Nookie1986 [14]

Answer:

0.033g

Explanation:

Hello,

In this case, since 11 mg per kilogram of body weight has the given lethality, the mg that turn out lethal for a chicken weighting 3 kg is computed by using a rule of three:

11mg\longrightarrow 1kg\\\\x\ \ \ \ \ \ \longrightarrow 3kg

Thus, we obtain:

x=\frac{3kg*11mg}{1kg}\\ \\x=33mg

That in grams is:

=33mg*\frac{1g}{1000mg} \\\\=0.033g

Regards.

If an element has 10 protons and 11 neutrons and 10 electrons, which expression correctly identifies the element?
Sunny_sXe [5.5K]
When the number of protons and electrons are equal, that means the element is neutral. So, to know the element, find the element with an atomic number of 10. That would be Neon. Next, solve the mass number.

Mass number = protons +neutrons = 10+11 = 21

Thus, the expression should be written as shown in the attached picture.

Which direction does heat flow from
Bas_tet [7]
And unless people interfere, thermal energy — or heat — naturally flows in one direction only: from hot toward cold. Heat moves naturally by any of three means. The processes are known as conduction, convection and radiation. Sometimes more than one may occur at the same time
