Please Help giving high points. Perform the following mathematical operation, and eport the answer to the correct number of significant figures. 4568/1.3 = [?]​

Answers

Answer:

1.3 is the value with the lowest sig figs in your question. So we have 2 sig figs.

4568/1.3 = 3513.84615

Now let's change the answer in sig figs.

We know that trailing zeros don't actually count as part of sig figs.

So we can round the answer to 3500, having the 2 sig figs (3 and 5) while the trailing zeros don't count.

Final answer = 3500

A group of students were asked to design a device that converts light energy into heat. They built a small solar oven using a tin can and aluminum foil. The device reflects light into the can, warming up its contents.
Which action would most improve the design of the solar oven?
O A. Add a mirror to reflect light away from the can.
O B. Use hand lenses to focus the light into the can.
O c. Add a fan to make sure the food is evenly warmed.
O D. Change the tin can to a box with a lid to Increase cooking space.

Answer:

answer is b

Explanation:

I think it is b. I don't know what land lenses are but focusing light on the can would heat it up more.

If two atoms have very different electronegativities, will this for me ionic bond or a covalent bond

Answers

Answer:

It will be a covalent bond.

Explanation:

When two atoms combine, the difference between their electronegativities is an indication of the type of bond that will form. If the difference between the electronegativities of the two atoms is small, neither atom can take the shared electrons completely away from the other atom and the bond will be covalent.

why does hydrogen fluoride have a high boiling point

Answers

The intermolecular bonding for HF is van der Waals, whereas for HCL, the intermolecular bonding is hydrogen. Since the van der Waals bond is stronger than hydrogen, HF will have a higher boiling temperature. Since the covalent bond is stronger than van der Waals, HF will have a higher boiling temperature.

what type of elements are involved in covalent bonding

Answers

Answer:

non-metals

Explanation covalent bonds occur between elements that are far apart on the periodic table.

The types of elements that are significantly involved in covalent bonding are known as non-metals.

What is Covalent bonding?

Covalent bonding may be defined as a type of chemical bonding that may involve the mutual sharing of electrons in order to construct electron pairs between atoms of non-metals. These electron pairs which are formed between atoms are known as bonding pairs or shared pairs.

According to the context of this question, covalent bonds are generally formed between nonmetals. While metallic bonds are the type of chemical bonds which are typically formed between the metallic element.

Another type of bonding may also be formed between elements. This type of bonding is known as Ionic bonding. This chemical bonding mat generally arises between metals and non-metals.

Therefore, the types of elements that are significantly involved in covalent bonding are known as non-metals.

The relationship between acceleration due to gravity (g), mass of earth (M) and the radius of earth (R) is [tex]g = \frac{GM}{R^2} [/tex].

What is weight of an object?

The weight of an object is determined as the product of the object's mass and acceleration due to gravity.

F = mg

The gravitational force on objects in the universe

The gravitational force between two objects in the universe is directly proportional to the product of mass of the objects and inversely proportional to the square of the distance between the objects.

[tex]F = \frac{GmM}{R^2} [/tex]

[tex]mg = \frac{GmM}{R^2} \\\\ g = \frac{GM}{R^2} [/tex]

where;

M is the mass of the earth

R is the radius of the earth

What is an energy level?

Electrons present in an atom revolve in different orbits which are stationary states and are also called as energy levels. The energy levels are numbered as integers which are also called as principal quantum numbers.

Energy of the stationary state is given as E= -R

1/n² where R

is the Rydberg's constant. When an electron is excited, and it moves from lower to higher energy levels there is absorption of energy, while when it moves from higher energy level to lower energy level it radiates or gives out energy in the form of radiation.

They can also be defined as the distances between electron and nucleus of an atom . Electrons present in K energy level have least energy .Energy level diagrams are studied to understand nature of bonding , placement of electrons in orbits and and elemental behavior under certain conditions.
