which one goes where? ​

Answer:

0.332mL

Explanation:

11.4g/mL is 11.4 for every one mL

11.4g / 1mL needs to be the same ratio as 3.78g to an unknown value, let's call it x.

11.4g/1mL = 3.78g/x

We cross multiply: 1*3.78 = 11.4*x

3.78 = 11.4x

Now isolate x by diving 11.4 on both sides: 0.331578974mL = x

In chemistry, we usually round to significant figures, so our answer would be 0.332mL

Answer:

Electron → Negative Charge → Outside Nucleus → Less than 1 amu

Proton → Positive Charge → Inside Nucleus → 1 amu

Neutron →  No charge → Inside Nucleus → 1 amu

The atomic mass of helium is the bottom number underneath its symbol. The atomic mass is 4.0026. Since helium only have 2 protons, then helium has 2 neutrons because you subtract the atomic number from the atomic mass to find the neutron count. The atomic number is the top number above "He". The atomic number of helium is 2 and it refers to the amount of protons.

There is really no difference thermal energy and heat are pretty the same thing.

Answer:

Thermal energy refers to the energy contained within a system that is responsible for its temperature. Heat is the flow of thermal energy.

Answer:

Chlorine(Cl) is a bit more negative than Sodium(Na)

Explanation:

Cl has an electronegativity of 3.0

Na has an electronegativity of 1.0

Answer:

The bond between Na & CI is ionic. One atom will form a a negative ion and the other will form a positive ion. Sodium (Na) has 1 valence electron, so it will give it away in order to become stable (octet rule). Chlorine has 7 valence electrons. So when Na and Cl bond, chlorine will take sodium's 1 valence electron and become stable. Now both atoms are stable but each form a specific ion. Since sodium lost its electron, It now has an imbalance where there are more protons than neutrons. This makes the sodium atom a positively charged ion (Na+). Since chlorine gained an electron, it now has an inbalance where there are more electrons than protons. This makes the atom a negatively charged ion (Cl-)

Answer:

0.282 moles

Explanation

I assume you meant How many moles is 1.7 × 10^23 atoms of Ne?

1 mole is 6.02X10^23        .Avogados number=

(1.7X10^23)/(6.02X10^23)= 0.282 moles

Answer:

[tex]\boxed {\boxed {\sf 0.28 \ mol \ Ne}}[/tex]

Explanation:

We are asked to find how many moles are in 1.7×10²³ atoms of Ne or neon.

Atoms are converted to moles using Avogadro's Number or 6.022 ×10²³. This is the number of particles (atoms, molecules, formula units, etc.) in 1 mole of a substance. For this problem, the particles are atoms of neon.

We convert using dimensional analysis, so a conversion factor (using Avogadro's Number) must be set up.  

[tex]\frac {6.022 \times 10^{23} \ atoms \ Ne}{ 1 \ mol \ Ne}[/tex]

We are converting 1.7×10²³ atoms of Ne to moles, so we multiply the ratio by this value.

[tex]1.7 \times 10^{23} \ atoms \ Ne *\frac {6.022 \times 10^{23} \ atoms \ Ne}{ 1 \ mol \ Ne}[/tex]

Flip the ratio so the units of atoms of neon cancel out.

[tex]1.7 \times 10^{23} \ atoms \ Ne *\frac { 1 \ mol \ Ne}{6.022 \times 10^{23} \ atoms \ Ne}[/tex]

[tex]1.7 \times 10^{23} *\frac { 1 \ mol \ Ne}{6.022 \times 10^{23} }[/tex]

[tex]\frac { 1.7 \times 10^{23}}{6.022 \times 10^{23} } \ mol \ Ne[/tex]

Divide.

[tex]0.2822982398 \ mol \ Ne[/tex]

The original measurement of atoms (1.7×10²³) has 2 significant figures (1 and 7). Our answer must also have 2 significant figures. For the number we found, that is the hundredth place.

The 2 in the thousandth place tells us to leave the 8 in the hundredth place.

[tex]0.28 \ mol \ Ne[/tex]

1.7×10²³ atoms of Neon are equal to approximately 0.28 moles of neon.

Answer:

This is because some molecules contain only one chemical element, and a compound, by definition, contains 2 or more elements.

Explanation:

Consider molecular Hydrogen (H₂) as an example. It is a molecule, albeit very simple, because it is made up of multiple atoms (2 Hydrogen atoms, to be precise). It is not a compound, however, because it only contains one chemical element: Hydrogen.

The maximum number of electrons in any orbital is two regardless of the nature of the orbital

Answer:

speed inscreases mass decrreases, but when no friciton mass dont matter

Explanation:

Mass does not affect speed directly, but it does affect how fast an object can change its speed by accelerating or decelerating. Objects with larger masses require more time for acceleration or deceleration compared to lighter objects. The law of inertia states that objects that are still remain still and that objects in motion remain in motion regardless of the object's mass.

Another method tested in study to produce sodium polyacrylate as an alternative to current methods began with Butyl acrylate acrylic acid copolymer and poly(butyl acrylate)

Explanation:

They were synthesized via suspension polymerization by using butyl acrylate as the main monomer and acrylic acid as the secondary monomer

I suggest you get more info from wikipedia cause it helped me alot

The monomers used to make sodium polyacrylate polymer chains acrylic acid (H₂C=CHCOOH) and its sodium salt (H₂C=CHCOONa) .

Monomers are small organic molecules that have the capability to bond to form larger molecules known as polymers.

The reaction between acrylic acid (H₂C=CHCOOH) and its sodium salt (H₂C=CHCOONa) produces sodium polyacrylate.

A long-chain copolymer made up of alternate units of acrylic acid and sodium acrylate is the result of this process.

Acrylic acid and sodium acrylate form a copolymer, which is a polymer made up of two distinct monomers.

total mechanical energy is the sum of kinetic energy and potential energy so it will remain same always

Answer:

Explanation:

Because the kinetic and potential energy are constant. A good example of kinetic and potential energy are throwing a ball up. It leaves your hand with kinetic energy. When it reaches the top it doesn’t have any kinetic force but potential energy equal to the kinetic energy the ball had when you threw it up. And, when it comes back to your hand it has the same kinetic energy it had when it left your hand. Thus, the sum of the kinetic energy plus potential energy is a constant.

Answer: good

Answer:

No, it does not demonstrate conservation of matter because there are not the same number of atoms of the products and reactants. For example, the carbon dioxide and water reactants are not represented on the product side of the equation.

Answer:

Liquid water (H2O) is formed when two gases, hydrogen (H2) and oxygen (O2), react. ... The difference in the properties of water can be attributed to physical changes to the hydrogen and oxygen atoms on a subatomic level. The properties of the gases are combined to give water its properties.
