Answer:

Explanation:

Sodium atoms has 1 valence electron, the 3s electron. If it can lose the single 3s electron, it's outer shell will have 8 valence electrons from the lower energy shell: 2s^22p^6, the same electron configuration as neon. This is a more stable arrangement.

Sodium want to give up an electron and "will always want to give up an electron* because less energy is needed to remove the one valence electron of sodium in order to have an octet configuration. This is the reason why sodium and other alkali metals form positive ions so easily.

<h2>Case study</h2>

For instance: In forming an ionic bond, the sodium atom, which is electropositive, loses its valence electron to chlorine. The resulting sodium ion has the same electron configuration as neon (1s2 2s22p6). It has a +1 charge, because there are 11 protons in the nucleus, but only 10 electrons around the nucleus of the ion

One sphere has a radions of 181 cm, another has a radius of 5.01 cm. What is the difference in volume (in cubic centimeters) bet

PSYCHO15rus [73]

Answer:

$2.4*10^{7}cm^{3}$

Explanation:

First you should calculate the volume of a big sphere,so:

$V_{big}=\frac{4}{3}\pi r^{3}$

$V_{big}=\frac{4}{3}\pi (181cm)^{3}$

$V_{big}=2.4*10^{7}cm^{3}$

Then you calculate the volume of a small spehre, so:

$V_{small}=\frac{4}{3}\pi r^{3}$

$V_{small}=\frac{4}{3}\pi (5.01cm)^{3}$

$V_{small}=5.3*10^{2}cm^{3}$

Finally you subtract the two quantities:

$V_{big}-V_{small}=2.4*10^{7}cm^{3}-5.3*10^{2}cm^{3}$

$V_{big}-V_{small}=2.4*10^{7}cm^{3}$

Fatty acid with only single covalent bonds is said to be

ohaa [14]

These are known to be saturated.
The definition of a saturated fatty acid is that the carbon chain coming off of the acid group contains only single bonds. An unsaturated fatty acid contains at least one double bond in the carbon chain coming off of the acid group. Saturated fats are usually fats (solid at room temperature) while unsaturated fats can be oils (liquid at room temperature) this is because the single bonds in the saturated fats give the molecule a shape that can stack on another saturated fat molecule more easily which makes the melting points higher. The double bonds (usually referring to cis double bonds since trans double bonds are in trans fats) in unsaturated fats give the molecule a shape that cannot stack on another unsaturated fat molecule easily which makes the melting point lower.

I hope this helps. Please let me know if anything is unclear or if you want further explanation.

7. When solid carbon reacts with oxygen gas to produce carbon dioxide gas, woul the triangle H value be on the reactant or produ

garik1379 [7]

When solid carbon reacts with oxygen gas to produce carbon dioxide gas. the deltaH (enthalpy change ) value is negative .DeltaH would be on the product side of the equation.

<h3>What is enthalpy change? </h3>

In a thermodynamic system, energy is measured by enthalpy. Enthalpy is a measure of a system's overall heat content and is equal to the system's internal energy plus the sum of its volume and pressure.

Knowing whether q is endothermic or exothermic allows one to characterise the relationship between q and H. An endothermic reaction is one that absorbs heat and demonstrates that heat from the environment is used in the reaction, hence q>0 (positive). For the aforementioned equation, under constant pressure and temperature, if q is positive, then H will also be positive. In a similar manner, heat is transferred to the environment when it is released during an exothermic reaction. Thus, q=0 (negative). Therefore, if q is negative, H will also be negative.
