Most reactive are on the far left.
Murrr4er [49]3 years ago
3 0

Answer: Option (d) is the correct answer.

Explanation:

Metals are the substances that have more number of electrons. In order to attain stability, metals lose electrons and thus becomes positively charged.

A metal with less number of valence electrons will be more reactive because it will readily lose its valence electrons to become stable.

For example, atomic number of potassium is 19 with electronic distribution is 2, 8, 8, 1. Potassium is a group I element. So, to become stable it will lose its 1 extra electron readily.

Therefore, we can conclude that the most reactive metals on the periodic table are placed on to the far left.

What would be the vital capacity be for a man that has a tidal volume of 500mL, a residual volume of 1100 mL, an expiratory rese
dezoksy [38]

The vital capacity will be 4600ml.

<h3>What is vital capacity?</h3>

The highest amount of air a person can inhale following their maximal exhalation is known as their vital capacity. It is equivalent to the total of the inspiratory, tidal, and expiratory reserve volumes. It roughly corresponds to Forced Vital Capacity. A wet or conventional spirometer can assess a person's vital capacity.

Normal people have a 3 to 5-liter vital capacity.

It enables simultaneous inhalation of the greatest possible volume of clean air and exhalation of the greatest possible volume of stale air. So, by increasing gaseous exchange between the body's various tissues, it improves the amount of energy available for bodily function.

VC = TV₊IRV₊ERV

where,

VC = Vital capacity

TV = Tidal volume

IRV = inspiratory reserve volume

ERV = expiratory reserve volume

VC = 500 ₊ 3000 ₊ 1100

VC = 4600ml

Therefore, the vital capacity will be 4600ml.

Is the autoionization of water endothermic or exothermic?
dexar [7]

Why would it be difficult to sift the iron fillings from the sand
slamgirl [31]

Explanation:

Sand and iron fillings have the same size of particles.

It would be difficult to use a mesh to separate them. Also, sometimes , the iron filing clings well to the surface of the sand particles.

The best way to separate them is to use a bar magnet. The magnetic properties of the iron fillings will get it attracted to the bar magnet leaving the sand particles behind.

freezing a sealed full bottl of water leads to a broken bottle and freezing a sealed full flexible wall container of n butyl alc
Nataly [62]

Answer:

See explanation

Explanation:

We know that water begins to expand at 4°C. This is generally referred to as the anomalous behavior of water.

The implication of this is that ice has a greater volume than water. Thus ice is less dense than liquid water.

n-butyl alcohol has much less density than water. This accounts for the fact that water upon freezing breaks the bottle while n butyl alcholol leads to a container with concave walls.

Hence the density of ice is much higher than the density of n butyl alcohol.
