When a sodium (Na) atom forms an ion so that it looks like a noble gas with a full valence shell, what will its charge be?

Chemistry
1 answer:
Setler79 [48]3 years ago
5 0

Answer:

I believe 1+

Explanation:

when Na loses 1 electron in the outer shell it has 8 valence protons on it's new most outer shell. so now it has 11 protons and 10 electrons. that extra proton (positively charged) adds one extra charge. so +1

A container of gas has a volume of 280 mL at a temperature of 22 Celsius if the pressure remains constant what is the volume 44
d1i1m1o1n [39]

Answer:

300.9mL

Explanation:

Given parameters:

V₁  = 280mL

T₁ = 22°C

T₂  = 44°C

Unknown:

V₂ = ?

Solution:

To solve this problem, we apply Charles's law;

  it is mathematically expressed as;

            \frac{V_{1} }{T_{1} }  = \frac{V_{2} }{T_{2} }

We need to convert the temperature to kelvin;

       T₁ = 22°C = 22 + 273 = 295K

       T₂  = 44°C = 44 + 273  = 317K

Input the parameters and solve;

        \frac{280}{295}   = \frac{V_{2} }{317}

  V₂ x 295 = 280 x 317

  V₂ = 300.9mL

Describe what happened when sodium chloride (salt) was placed in water in the video What happens when stuff dissolves?"
Sonja [21]

Answer:

-

Explanation:

Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules, as this diagram shows. Once this happens, the salt is dissolved, resulting in a homogeneous solution.

Determine whether the disruption of the bonds or attractions occurs during protein hydrolysis or protein denaturation.
Aleonysh [2.5K]

Answer:

The disruption of the bonds or attractions occurs during protein hydrolysis which results in the loss for the primacy structure. The peptide bonds is the bond affected in this scenario.

The disruption of the bonds however only exist in the process of denaturation and this results in a change in the confirmation which could be secondary, tertiary, and quaternary structural related. And example of the bonds affected include salt bridges, disulfide bridges, hydrogen bonds etc.

What does iron do for the human body(two paragraphs)
Nitella [24]

Answer:

Hey mate....

Explanation:

This is ur answer.....

<em>Iron is an essential element for blood production. About 70 percent of your body's iron is found in the red blood cells of your blood called hemoglobin and in muscle cells called myoglobin. Hemoglobin is essential for transferring oxygen in your blood from the lungs to the tissues. Myoglobin, in muscle cells, accepts, stores, transports and releases oxygen.</em><em> </em><em>About 6 percent of body iron is a component of certain proteins, essential for respiration and energy metabolism, and as a component of enzymes involved in the synthesis of collagen and some neurotransmitters. Iron also is needed for proper immune function.</em><em> </em><em>About 25 percent of the iron in the body is stored as ferritin, found in cells and circulates in the blood. The average adult male has about 1,000 mg of stored iron (enough for about three years), whereas women on average have only about 300 mg (enough for about six months). When iron intake is chronically low, stores can become depleted, decreasing hemoglobin levels.</em><em> </em><em>When iron stores are exhausted, the condition is called iron depletion. Further decreases may be called iron-deficient erythropoiesis and still further decreases produce iron deficiency anemia.</em>
