mass = 5.05 g

density = 3.25 g/mL

We have

[tex]volume = \frac{5.05}{3.25} \\ = 1.5538461...[/tex]

Answer:

a) 0.000765kg

b) 1340mg

c) 0.0342g

Explanation:

a) 1000g = 1kg

0.765g= 0.765/ 1000

= 0.000765g

b) 1g = 1000mg

1.34g = 1.34 × 1000

= 1340mg

c) 1000mg = 1g

34.2mg = 34.2/1000

= 0.0342g

Answer:

peer reviewing

Explanation:

Its peer reviewing because there peers and there reviewing eachothers work

The process whereby scientists check each other’s work is peer reviewing.

Peer group are the groups of people of same age, same background with same interest.

In the peer reviewing process group of members will check, evaluate and correct each others work, which in turn help the members of the group to update their work.

Hence, option (c) is correct i.e. peer reviewing is the process whereby scientists check each other’s work.

Answer:

B. How many of each atom are present in the compound

D. the simplified ratio of atoms in relation to each other

Explanation:

In a chemical formula, chemical elements or atoms are represented by a chemical symbol for example Fe for iron and Na for sodium, and the number of each atom is represented by a subscript such as CO2, where 2 is a subscript representing 2 atoms of oxygen.

A subscript represents the number of each atom in the compound and the simplified ratio of atoms in relation to each other. The simplified ratio of atoms in relation to each other means subscript shows the contribution of both the atoms in the compound, for example: N2 + 3H2 => 2NH3, it means the subscript showing the ratio or proportionate of atoms that is 2:2 for both nitrogen and hydrogen.

The subscript is always written below and to the right of the chemical symbol.

Hence, the correct answer is "B. How many of each atom are present in the compound and D. the simplified ratio of atoms in relation to each other"

The statement describes a molecule that has a trigonal pyramidal molecular shape is "The molecule has a trigonal planar electron domain geometry with two lone pairs".

Because is you put water and sand in a container you can separated by boiling the water and all the water would evaporate and the sand would stay.

Answer:

Adding soap would cause the paper clip to fall through the water and onto the base of the dish because soap is a surfactant.

Explanation:

The concept surface tension is used here to determine what happens to the paperclip when a drop of dish soap is added to the water. Here the paperclip sink into the water.

The property exhibited by the surface of a liquid in order to resist the action of an external force because of the cohesive nature of the molecules is known as the surface tension. Due to this property the surface of a liquid behaves as an extended elastic membrane.

The paperclip float on water because of the high surface tension as the water molecules at the surface are strongly attracted among themselves. But on adding one or two drops of dish soap to water causes the paperclip to sink.

The addition of the drops of dish soap to the water weakens the attraction among the water molecules and thereby lowers the surface tension. As a result of this the surface film disappears and the paperclip sink into the water.

Thus the paperclip fall into the water when a drop of dish soap is added to the water.

Explanation:

An intrinsic property is a property that is internal, that is, it characterizes the substance under study. The possession of an intrinsic property depends on the nature of the substance. An intrinsic property does not depend on amount of substance but on the nature of the substance.

Examples of intrinsic properties include; Density. Solubility, Melting Point, Freezing Point, Boiling Point, Conductivity etc.

Intrinsic properties really represent the matter that is being studied. For instance, the boiling point of water will always be 100°c. No other liquid can boil exactly at that temperature. Hence, this intrinsic property can always be used to identify an unknown liquid as water.

The students were right, studying intrinsic properties accurately represent the matter that is being studied.

Answer:bet

Explanation:

Answer:

1   Ca(OH)2 + 1  (NH4)2SO4   ---> 1 CaSO4 + 2 NH3 + 2 H2O

Explanation:

The photo I attached should make more sense as an explanation.

When balancing equations, the first and most important step is to count the # of each type of element on each side.

In this problem there are 5: Ca, O, H, N, and S.

Once you do that you can begin balancing.

Here is the initial tally for the elements in this problem:

On the left.....

Ca - 1

N - 2

S - 1

O - 6

H - 10

On the right.....

Ca - 1

N - 1

S - 1

O - 5

H - 5

Looking at these values, we can see N, O, and H all need adjusting the right side. You should never start balancing with O or H unless they are the only elements that need adjusting. They usually balance out with the rest of your work or with water in the end.

So given all of that, you should start balancing with N on the right. Giving NH3 a coefficient of 2 will change the number of Nitrogen atoms on the right to 2. Be careful though! It will also change the number of Hydrogen atoms from 5 to 8 (because (2*3) =6 and 6+2 =8).

Let's tally our numbers again.

On the left..... (these should be unchanged)

Ca - 1

N - 2

S - 1

O - 6

H - 10

On the right.....

Ca - 1

N - 2

S - 1

O - 5

H - 8

Okay, now we see only O and H need adjusting on the right. Luckily there is H2O so we can do that without impacting the number of other atoms.

Give H2O a coefficient of 2 and count the number of atoms on the right again.

On the right.....

Ca - 1

N - 2

S - 1

O - 6 (because 4 from CaSO4 plus 2 from 2H2O = 6)

H - 10 (6 from NH3 plus 4 from 2H2O = 10)

Do these numbers match what you have on the the left side of the equation? Yes! It is balanced so you do not need to adjust anymore. Your coefficients in the answer will be 1-1-1-2-2.

Answer: Christy won Molly by 12cm

Explanation:

Ist step

Molly's ;ong jump was 118.3cm

Christy long jump was 51.18inches

2nd Step

we change christy score to cm so we can compare

1 inch = 2.54cm.

therefore 51.18 inches = 51.18 x 2.54= 129.9972cm

Christy won molly by 129.9971cm-118.3cm=11.69 rounded to 12cm

Christy won Molly by 12cm
