Answer:

Nitrogen (ii) oxide

Explanation:

To know the IUPAC name for NO, we shall determine the oxidation number of N in NO.

NOTE: The oxidation number of oxygen (O) is always – 2.

Thus the oxidation number of N in NO can be obtained as follow:

N + O = 0 (ground state)

N + (– 2) = 0

N – 2 = 0

Collect like terms

N = 0 + 2

N = +2

Thus, the oxidation number of Nitrogen (N) in NO is +2.

Therefore, the IUPAC name for NO is Nitrogen (ii) oxide

Answer:

d = 9.5× 10⁻⁴ Kg/cm³

Explanation:

Given data:

Length of cube = 1.02 cm

Mass of cube = 0.001012 Kg

Density of cube = ?

Solution:

The length , height and width of cube is always same. Thus the volume of cube is,

Volume = length × height× width

Volume = 1.02 cm × 1.02 cm × 1.02 cm

Volume = 1.06 cm³

Density of cube:

d = 0.001012 Kg /1.06 cm³

d = 9.5× 10⁻⁴ Kg/cm³

Explanation:

a. Rub the magnet along the nail or knitting needle. Now try picking up the paper clip or

tack. Could your nail pick it up? How many can it pick up at once?

after rubbing the magnet with the nail, it could pick up 7 small paper clips.

b. Now try to make your magnet stronger by rubbing the magnet along the nail or knitting

needle for a longer time. Rub only in one direction, not back and forth. This will increase

the number of atoms that line up with the magnet. Try to pick up paper clips or

thumbtacks. How many can it pick up now?

after rubbing it a second time but for a longer period, it could pick up around 10, almost lifting the 11th.

Answer:

A. After rubbing the magnet with the nail, it could pick up 7 small paper clips.

B. After rubbing it a second time but for a longer period, it could pick up around 10 small paper clips, almost lifting the 11th one.

Answer:

H₂ + Cl₂ → 2HCl

Explanation:

The equation that is balanced and follows the law of conservation of mass is:

 H₂ + Cl₂ → 2HCl

Based on the law of conservation of mass "in a chemical reaction, matter is neither created nor destroyed but they combine with one another".

It suggests that the number of species on both sides of the expression must be the same.

 For the given reaction:

        H₂ + Cl₂ → 2HCl

             Reactant side              Product side

H                  2                                   2

Cl                  2                                   2

Answer:

6C(s) + 6H2(g) + 3O2(g) --------------------> C6H12O6(s).

Explanation:

One of the examples under the type of sugar; monosaccharide(simple sugar) is the glucose. Glucose(with IUPAC name as D-glucose) as a monosaccharide (simple sugar) has the molar mass of 180.156 g/mol and a Melting point of 146 °C.

Thus, the unbalanced chemical reaction for the formation of glucose is given below;

C(s) + H2(g) + O2(g) --------------------------> C6H12O6(s) ΔH°f = -1273.1KJ/mol.

The balanced chemical reaction for the formation of one mole of glucose is given as;

6C(s) + 6H2(g) + 3O2(g) --------------------> C6H12O6(s).

The balanced chemical equation for the standard formation reaction of solid glucose is: [tex]\mathbf{6C_{(s)} + 6H_{2(g)} +3O_2_{(g)} \to C_6H_{12}O_{6} _{(s)} \ \ \ }[/tex]

Glucose is a simple sugar of a class of carbohydrates known as monosaccharides. It is the principal metabolite for energy production in the human body.

The formation of solid glucose [tex]\mathbf{C_6 H_{12} O_6_{(s)}}[/tex] occurs by the reaction of carbon, hydrogen, and oxygen.

The reaction formation of the solid glucose is:

[tex]\mathbf{C_{(s)} + H_{2(g)} +O_2_{(g)} \to C_6H_{12}O_{6} _{(s)} \ \ \ \Delta H_f^0= -1273.1 \ kJ/mol}[/tex]

Now, the balanced chemical equation can be expressed as follows;

[tex]\mathbf{6C_{(s)} + 6H_{2(g)} +3O_2_{(g)} \to C_6H_{12}O_{6} _{(s)} \ \ \ }[/tex]

Answer:

This question appears incomplete

Explanation:

This question appears incomplete because of the absence of options. However, hydrogen is placed in group 1 because it has just one electron in it's outermost shell (which happens to be the only shell it has) just like every other group 1A/group 1 element. While helium is placed in group 8A/group 18 because it has a completely filled outermost shell (which is also the only shell it has) just like every other element in group 8A/group 18.

In the periodic table hydrogen is placed in Group 1A (group 1) and helium is placed in Group 8A (group 18). The most likely reason for this is configuration, energy level and properties.

Hydrogen is located in group 1 of the periodic table, although its electronic configuration is 1s¹ and its properties do not correspond to those of the alkali metals of that group. But in its electronic configuration you can see that it has only one electron in its outermost shell (which turns out to be the only shell it has), just like any other element of group 1A /group 1, so it is located in that group.

On the other hand, although the electronic configuration of helium is 1s², this element does not appear in group 2 of the periodic table of elements, but is placed in group 18. This is because it has the energy level complete, so it has the properties of a noble gas, that is, it is inert (it does not react), and it is a colorless and odorless monatomic gas.

In summary, in the periodic table hydrogen is placed in Group 1A (group 1) and helium is placed in Group 8A (group 18). The most likely reason for this is configuration, energy level and properties.

Answer:

Sunlight provide light energy.

Chlorophyll absorb light.

Explanation:

Sunlight provide light energy or give light energy from sun and it is use to produce glucose from carbondioxide and water which is also a source of energy.

Chlorophyll absorbs light energy and use it to convert carbondioxide and water into glucose and oxygen or it captures sun rays and produce glucose and water.

Answer:

This approximation of mass can be used to easily calculate how many neutrons an element has by simply subtracting the number of protons from the mass number. Protons and neutrons both weigh about one atomic mass unit or amu. Isotopes of the same element will have the same atomic number but different mass numbers.

Answer:

photosynthesis occurs so the plants can create energy from carbon dioxide and sunlight.  

Explanation:

so basiclly it occurs so the plants can create energy to stay alive.

Answer:

Explanation:

photosynthesis occurs basically to help plants get light in order to produce its necessary daily production of nutrients needed for animals to get carbohydrates froms which is eaten by animals since it gives energy. so basically photosynthesis--> energy --> carbs for mammals to eat!

the green colour reflects off the plant so it is not absorbed by the chloroplasts  rather all colours are absorbed just not green.

and every organic material on earth is produced by these cells which convert energy from the sun into nutrient filled plants.. its essential for the CO2 cycle ,  and since they conduct photo synthesis they are lowest level in the food chain so basically its important since they create nutrients for our plants.

Answer:

it would round down to 14.2

Explanation:

the 35 is below 50 so it goes down, and it rounds down to 14.2 instead of, if if was, say, 14.62 then that would round up bc the decimal is higher than 50.

but since it is 235, then it rounds down to 14.2
