Answers

Answer 1

Answer:

Explanation:

I gave this formula as

What you should get - what you got

---------------------------------------------------   * 100

What you should get

Suppose you are talking about the specific heat of copper and you did a lab and did it fairly well and the specific heat came out to be 0.33

That's what you got, 0.33

What you should get is 0.35 according to the table you've given us.

% error = 0.35 - 0.33

                -------------- * 100

                      0.35

% error = 0.02 * 100/ 0.35

% error = 2/0.35

% error = 5.71

Now here is the really hard part. You have to decide what a positive error is and what a negative error.

A positive error using this formula means you are too low.

A Negative error means that you are too high, just the opposite of what you might think.

Answer 2

Can you show us the experimental value?

So basically, the accepted value would be under the Specific heat capacity of metal (e.g. 0.90, 0.35, 0.44, 0.12).

Your experimental value would be the specific heat capacity that you got from the lab.

You would first substract the experimental value from the accepted value

[tex]accepted \: value - experimental \: value [/tex]

and then you would divide the result by the experimental value

[tex]result \div experimental \: value[/tex]

and then, you would multiply the result of that by a hundred to get your percentage

[tex]result \times 100 = \% \: error[/tex]

//

The image shown is an example.

0.90 is our accepted value.

0.88 is our experimental value.

The overall percentage error I got is %2.27

If sodium (Na) bonds with chlorine (Cl), which statement is true?

An electron is transferred from sodium to chlorine and an ionic bond is
formed.
An electron is shared between sodium and chlorine and an ionic bond is
formed.
An electron is transferred from sodium to chlorine and a covalent bond is
formed.
An electron is shared between sodium and chlorine and a covalent bond is

Answers

Answer:

First Statement is correct

Explanation:

An electron is transferred from sodium to chlorine and ionic bond is formed.

Hope it help!!

If sodium ( Na ) bonds with chlorine ( Cl ), then an electron is transferred from sodium to chlorine and an ionic bond is formed. Therefore, option A is correct.

What is ionic bond ?

The main interaction taking place in ionic compounds is ionic bonding, a form of chemical bonding that includes the electrostatic attraction between two atoms or ions with dramatically differing electronegativities.

When the ionic character is larger than the covalent character, i.e., when there is a significant difference in the electronegativity between the two atoms, the bond is more polar than when the electrons are divided more evenly in covalent bonding.

The ionic bond found in the salt sodium chloride is an illustration of this type of connection. The valence electron from sodium is transported to chloride's outer electron shell.

Thus, option A is correct.

Answers

Answer:

D

Explanation:

because the rest don’t make any sense

A light-year unit is very large and distances in space are very large. Therefore, the correct option is option D.

What is distance?

No matter the direction of the journey, distance is the overall path that an item in motion has traveled. Since just the length of the path travelled is calculated as well as the motion's direction is ignored, distance is referred to as a scalar number. The distance can only ever be positive; it can never be 0 or negative.

Displacement generally defined as the overall alteration of an object's location and motion direction. Displacement is recognized as a vector quantity since it takes into consideration both the directions of the motion and the amount of the changing position. Displacement may be zero, positive, or negative. A light-year unit is very large and distances in space are very large.

Therefore, the correct option is option D.

Answers

As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases.

Why Doesn't The Earth Usually Feel Solar Winds?

Answers

Answer:

When the solar winds approach the Earth, the magnetosphere (part of the Earth's natural magnetic defenses) deflects/repels most of the charged particles and shields our planet's surface from the winds. Sometimes, however, the magnetosphere isn't strong enough to block the Earth from these winds, so they do hit Earth and may cause catastrophic consequences, such as ruin power grids, cut off telecommunications (cell service/calls), etc.

Now molecules: Choose... molecules of H 2 + Choose... molecules of O 2 → Choose... molecules of H 2 O

Answers

Consider this balanced chemical equation:
2 H2 + O2 → 2 H2O
We interpret this as “two molecules of hydrogen react with one molecule of oxygen to make two molecules of water.” The chemical equation is balanced as long as the coefficients are in the ratio 2:1:2. For instance, this chemical equation is also balanced:
100 H2 + 50 O2 → 100 H2O
This equation is not conventional—because convention says that we use the lowest ratio of coefficients—but it is balanced. So is this chemical equation:
5,000 H2 + 2,500 O2 → 5,000 H2O
Again, this is not conventional, but it is still balanced. Suppose we use a much larger number:
12.044 × 1023 H2 + 6.022 × 1023 O2 → 12.044 × 1023 H2O
These coefficients are also in the ratio of 2:1:2. But these numbers are related to the number of things in a mole: the first and last numbers are two times Avogadro’s number, while the second number is Avogadro’s number. That means that the first and last numbers represent 2 mol, while the middle number is just 1 mol. Well, why not just use the number of moles in balancing the chemical equation?

Answer:
