What happens if you put a cat in the microwave?

1 answer:

8 0

She said that the exposure to the radiation in the microwave would have cooked the animal's internal organs. She said: 'It is a horrific case in the fact that the death of the cat would have been prolonged and it is unimaginable what it would have gone through taking some time to die.

Hydrochloric acid reacts faster with powdered zinc than with an equal mass of zinc strips because the greater the surface area o

inysia [295]

Answer:

increases the frequency of particle collisions

Explanation:

One factor upon which the rate of reaction depends is the surface area of reactants.

According to the collision theory, reactions occur when reactant particles having the required (activation) energy collide with each other, this collision is inelastic. However, collision of particles having energies less than the activation energy results in elastic collisions and no chemical reaction.

The more the exposed surface area of reactants, the greater the number of particles that come into contact with each other and the more the chances of frequent effective collisions that lead to reaction.

Thus, powdered zinc reacts faster with hydrochloric acid than zinc strips

Enter the electron configuration for I+ using noble gas shorthand notation.

Maurinko [17]

Answer:

[Kr] 4d10 5s2 5p4

Explanation:

The Symbol I represents Iodine. It has atomic number of 53. The full electronic configuration is given as;

1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p5

However the question requested for the configuration of I+.

I+ is a cation and it simply refers to an iodine atom that has lost a single electron. The electronic configuration of I+ is given as;

1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p4

Using Noble gas shorthand representation, we have;

[Kr] 4d10 5s2 5p4

A 100 ml graduated cylinder with an inside diameter of 3.2 cm contains 34.0 g of gasoline and 34.0 g of water. what is the combi

Ivahew [28]

The volume of cylinder is 100 mL, inner diameter is 3.2 cm thus, radius will be:

$r=\frac{d}{2}=\frac{3.2 cm}{2}=1.6 cm$

Volume of layer formed= $\pi r^{2}h$ ...... (1)

Volume of layer is also equal to sum of volume of gasoline and water.

Density of gasoline is $0.702 g/cm^{3}$ and mass is 34 g thus, volume of gasoline will be:

$V=\frac{m}{d}=\frac{34 g}{0.702 g/cm^{3}}=48.43 cm^{3}$

Now, density of water is $1 g/cm^{3}$ and mass is 34 g thus, volume of water will be:

$V=\frac{m}{d}=\frac{34 g}{1 g/cm^{3}}=34 cm^{3}$

Adding both the volumes, volume of layer will be:

$Volume of layer=48.43 cm^{3}+34 cm^{3}=82.43cm^{3}$

Putting the values in equation (1) to solve for height of the layer,

$h=\frac{volume of layer}{\pi r^{2}}=\frac{82.43 cm^{3}}{3.14\times 1.6 cm\times 1.6 cm}=10.25 cm$

Thus, height of layer is 10.25 cm

The relationship between a law and a theory is

irinina [24]

I would say it’s ‘laws are based on complex theories’.

A scientific law predicts the outcome, while a theory presents a possible explanation to why this outcome is. A law is based of a theory that supports the most data.
