Answer:

Magenta.

Explanation:

Color absorption is a process that occurs when a light wave strikes an object. When a light wave strikes an object it either absorbs color or transmits the color, or reflects the color. When a light wave strikes a green object, it absorbs a magenta color.

Magenta is a combination of red and blue light, therefore, the colors that the green object will absorb is red. blue, or magenta light.

Here's the correct question:

The total ages of 5 children born at the intervals of 3 years each is 50 years. Find the age of the youngest and the oldest child.

From the information given, we can then make the following assumption with regards to their ages.

First child = y

Second child = y + 3.

Third child = y + 6

Fourth child = y + 9

Fifth child = y + 12

Therefore, y + y+3 + y+6 + y+9 + y+12 = 50

5y + 30 = 50

5y = 50 - 30

5y = 20

y = 20/5

y = 4

Youngest child = 4 years

Oldest child = y + 12 = 4 + 12 = 16 years

Physical science, in turn, can be divided into chemistry and physics. Chemistry is the study of matter and energy at the scale of atoms and molecules. ... Physics is the study of matter and energy at all scales—from the tiniest particles of matter to the entire universe but i dont really know if there is new information to discover

hope it help and if it doesnt sorry ;)

Answer:

I guess you mean by non element example. Non element examples have more than one elements. Carbon dioxide is a non element example since caebon dioxide has 2 oxygen atoms + 1 carbon atom = carbon dioxide.

I think catalyst is also a non element example because catalyst is inorganic which means that it is not a living thing. Since catalyst is in brass and brass is a non element example, I think catalyst is also a non element example.

Hope that helps, thank you !!

The given question is incomplete. The complete question is:

A reversible reaction is said to have reached equilibrium when which of the following conditions is established?

a. concentration of reactants and products are equal

b. opposing reactions cease

c. speeds of opposite reactions become equal

d. temperature of opposite reactions become equal

Answer: c. speeds of opposite reactions become equal

Explanation:

Equilibrium state is the state when reactants and products are present but the concentrations does not change with time.The state of equilibrium refers to the dynamic state as both forward and backwad reactions continue.

For a chemical equilibrium reaction, equilibrium state is achieved when the rate of forward reaction becomes equals to rate of the backward reaction.

Thus at chemical equilibrium, the amount of product and reactant remains constant because the rates of the forward and reverse reactions are equal.

Answer:

m = 79.1 grams

Explanation:

Given that,

Density, d = 2.26 g/mL

Volume occupies, V = 35 mL

We need to find the mass of the substance. We know that the density of an object is equal to the mass per unit volume. So,

d = m/V

[tex]m=d\times V\\\\m=2.26\ g/mL\times 35\ mL\\\\m=79.1\ g[/tex]

So, the mass of the substance is 79.1 grams.

Answer:

C. It may act as an insulator or a conductor.

Explanation:

Group B are the metalloids, so they have properties of both metals and nonmetals.

The statement which is most likely true for an element present in section B is: C. It may act as an insulator or a conductor.

A periodic table can be defined as an organized tabular array of all the chemical elements, which is typically arranged in order of increasing atomic number or number of protons (in rows).

In this diagram, the chemical element that is present in section B of the periodic table is a metalloid.

A metalloid can be defined as a chemical element that are typically intermediate between those of semiconductors, non-metals and metals.

In this context, the statement which is most likely true for an element present in section B is that it may act as an insulator or a conductor because it is a metalloid.

Answer:

0.2mol/dm³

Explanation:

Given parameters:

Mass of Na₂CO₃   = 10.6g

Volume of solution  = 500mL

Unknown:

Molarity of solution  = ?

Solution:

The molarity of a solution can be determined using the expression below:

 Molarity = [tex]\frac{number of moles }{volume}[/tex]  

     Number of moles  = [tex]\frac{mass}{molar mass}[/tex]  

Molar mass of Na₂CO₃ = 2(23) + 12 + 3(16)  = 106g/mol

   Number of moles  = [tex]\frac{10.6}{106}[/tex]   = 0.1mol

   Convert mL to dm³;

        500mL will give 500 x 10⁻³dm³or 0.5dm³  

So;

Molarity  = [tex]\frac{0.1}{0.5}[/tex]    = 0.2mol/dm³

Answer: B. The rate goes down

Explanation:

Answer: Decrease in size

Explanation:

Electronegativity is defined as the property of an element to attract a shared pair of electron towards itself.

On moving across a period from left to right,   the size of an atom decreases because the electrons get added to the same shell and the nuclear charge keeps on increasing. Thus the electrons get more tightly held by the nucleus.

As, the size of an element decreases, the valence electrons come near to the nucleus. So, the attraction between the nucleus and the shared pair of electrons increases. Thus electronegativity increases.

Answer:

16.8 L

Explanation:

From the question given above, the following data were obtained:

Number of mole of He = 0.750 mole

Volume of He =?

Recall:

1 mole of any gas occupy 22.4 L at STP. This also implies that 1 mole of He occupies 22.4 L at STP.

Finally, we shall determine the volume occupied by 0.750 mole of He. This can be obtained as follow:

1 mole of He occupied 22.4 L at STP.

Therefore, 0.750 mole of He will occupy = 0.750 × 22.4 = 16.8 L at STP.

Thus, 0.750 mole of He is equivalent to 16.8 L

[tex]8.876\times 10^{18}\ km^2[/tex]

Explanation:

In this problem, we need to convert [tex]8.876 \times 10^{12}\ m^2[/tex] to km².

We know that,

1 km = 1000 m

⇒ 1 km² = 10⁶ m²

So,

[tex]8.876 \times 10^{12}\ m^2=8.876 \times 10^{12}\times 10^6\ km^2\\\\=8.876\times 10^{18}\ km^2[/tex]

So, [tex]8.876 \times 10^{12}\ m^2[/tex] is equal to [tex]8.876\times 10^{18}\ km^2[/tex].

The question is incomplete, the complete question is;

Suppose 1.87g of nickel(II) bromide is dissolved in 200.mL of a 52.0mM aqueous solution of potassium carbonate. Calculate the final molarity of nickel(II) cation in the solution. You can assume the volume of the solution doesn't change when the nickel(II) bromide is dissolved in it. Be sure your answer has the correct number of significant digits. The answer is needed in M.

Answer:

0.0428 M

Explanation:

The equation of the reaction is;

NiBr2 + K2CO3 → NiCO3 + 2KBr

Number of moles of NiBr2 = mass/molar mass = 1.87 g/218.53 g/mol =

8.557 *  10^-3 moles

Now, we know that the Ni^2+ comes from the NiBr2. Also, the concentration of Ni^2+ in NiBr2 = concentration of Ni^2+ in NiCO3

So,

Concentration of Ni^2+ = 8.557 *  10^-3 moles/0.2 L = 0.0428 M

Skeletal structural diagram and bond-line drawing are similar;

Parts of the question appear missing: The number of hydrogen atoms in the attached example bond-line drawing is 6 hydrogen atoms

The reason the above value is arrived at for the attached example bond-line diagram is as follows;

A bond-line drawing is the diagram showing the molecular structure of a compound, such that covalent bonds within the molecule are represented by lines with the number of lines indicating the number of covalent bonds.

A single covalent bond is represented by one line, double bonds by two lines while three parallel lines represents a triple bond.

In bond-line drawing, the lines symbolically infer the carbon to carbon bonds while the bonds to the hydrogen atoms are implied noting that each carbon has four covalent bonds. Hydrogen atoms attached to other heteroatoms are indicated with an H.

The number of hydrogen shown in the example diagram can be found by noting that the number of covalent bonds between the carbon atoms are three, therefore, the atom of the fourth bond not shown with a line is to a hydrogen atom

There are six such carbon atoms, one of which is attached to an oxygen atom, which gives five hydrogen atoms located on the ring

There is one more hydrogen atom attached to the oxygen in the hydroxyl group, the total number of hydrogen is therefore;

5 hydrogen on ring + One hydrogen in the hydroxyl group = 6 hydrogen atoms
