Answer:

a difference in attitude

Explanation:

It's just not science. ... The big difference Popper identifies between science and pseudo-science is a difference in attitude. While a pseudo-science is set up to look for evidence that supports its claims, Popper says, a science is set up to challenge its claims and look for evidence that might prove it false.

Feather or bone when fall into food causing Physical  contamination.

Food waste, like a feather or a bone etc fall into food causing Physical  contamination because the contaminants such as feather and bone are mixed in the food physically not chemically. These contaminants can be removed through physical means such as with the help of hand.

Some contaminants mix with the food chemically means they react with the food and produce something new. Such type of contaminants are present in liquid form so we can conclude that feather or a bone etc when fall into food causing Physical  contamination.

Answer: Cell wall

Explanation: Cell wall is a unique structure found only in some specific organisms like plants, bacteria, fungi etc. The cell wall in plants is predominantly made up of a polysaccharide called CELLULOSE. This carbohydrate confers upon the cell "rigidity".

The cell wall is an additive material including the cell membrane that coats the external part of the cell of plants, hence, it gives plant cells their characteristic shape. The cell wall contributes to the overall flexible but rigid shape of the plant cell, protecting the cell against physical or chemical stresses.

Answer:

3 significant figures.

Explanation:

So, a mole is essentially a group of things. In this case, a mole of carbon dioxide will contain

6.022 ⋅ 10 [ by the 23rd power]

molecules of carbon dioxide. In other words, in order to have

1 molecule  of carbon dioxide, you need to have 6.022 ⋅ 10 [by the 23rd power] molecules of carbon dioxide.

You know that 5.00 ⋅ 10 [ by the 2nd power]  molecules of carbon dioxide are exhaled from the lungs when we breathe out. You can use Avogadro's constant as a conversion factor to help you figure out how many molecules are present.

Answer:

The third one: [tex]CuSO_4[/tex]

Explanation:

Again you are going to want to look at a periodic table so you can determine the symbol of each atom.

The symbol for copper is Cu, the symbol for sulfur is S and the symbol for Oxygen.

There is 1 atom of copper in the compound

So we have Cu

There is 1 atom of sulfur in the compound

So we would have CuS

There are 4 atoms of oxygen in the compound

So we would have [tex]CuSO_4[/tex]

Note that the little number at the bottom left after each symbol indicates how many atoms of that element are in that compound.

Answer: There are 20 protons neutrons in the atom

In case of a shortage in petroleum and natural gas, a company should find a way to make nylon without using natural resources.

Nylon is a very important material used in numerous applications. As a result of this, the demand for nylon as a raw material has genuinely been on the high side ever since.

However, nylon production depends on petroleum and natural gas. It is possible that there could be a shortage of these resources since they are obtained from the environment. In such cases, a company should  find a way to make nylon without using natural resources.

During electrolysis, a current is passed through the molten MgCl2, and when this happens, the Mg2+ ions move to the negative electrode where they PICK UP OR GAIN ELECTRONS. This is reduction. The Cl- ions move to the positive electrode where they LOSE ELECTRONS. This is oxidation.

Answer:Wood for barbucue.

Explanation:

Answer:

b) (i): 0.91 Amgstroms

(ii): 9.1 × 10^-11 Angstroms

(c): Volume = 20 Angstroms

Explanation:

• Let's first convert the units:

[tex]{ \rm{1 \:nanometre = 1 \times {10}^{ - 9} \: metres} } \\ { \rm{10 \: angstroms = 1 \times {10}^{ - 9} \: metres}} \\ { \rm{1 \: micrometer = 1 \times {10}^{ - 6} \: metres = 1000 \: nm}} \\ \\ { \rm{1 \: {nm}^{3} = 1000 \: {angstroms}^{3} }}[/tex]

Question (b)

[tex]{ \rm{radius = \frac{diameter}{2} }} \\ \\ { \rm{radius = \frac{0.182}{2} }} \\ \\ { \rm{radius = 0.091 \: nm}} \\ \\ { \mathfrak{ answer{ : { \rm{radius = (0.091 \times 10) \: angstroms}}}}} \\ \\ { \rm{radius = 0.91 \: angstroms}}[/tex]

[tex]{ \rm{radius = 0.091 \: nm}} \\ \\ { \rm{radius = 0.091 \times( 1 \times {10}^{ - 9} ) \: metres}} \\ \\ { \rm{radius = 9.1 \times {10}^{ - 11} \: m }}[/tex]

[tex]{ \rm{volume = (0.5 \times 0.2) \: nm \times 0.0002 \: micrometer}} \\ \\ { \rm{volume = 0.5nm \times 0.2nm \times (0.0002 \times 1000)nm}} \\ \\ { \rm{volume = 0.5 \times 0.2 \times 0.2 \: nm {}^{3} }} \\ \\ { \rm{volume = 0.02 \: nm {}^{3} }} \\ \\ { \rm{volume = (1000 \times 0.02) \: angstroms {}^{3} }} \\ \\ { \rm{volume = 20 \: angstroms}}[/tex]

Answer:

In a chemical reaction, substances (elements and/or compounds) called reactants are changed into other substances (compounds and/or elements) called products. You can't change one element into another in a chemical reaction — that happens in nuclear reactions.

Explanation:

Explanation:

Thus, reactions in which products can be converted to reactant is called Reversible reaction.

Answer: as the wavelength gets shorter, the energy increases; as the wavelength gets longer, the energy decreases. The greater the energy, the larger the frequency and the shorter (smaller) the wavelength.

Answer:

Just as wavelength and frequency are related to light, they are also related to energy. The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy. The energy equation is E = hν.
