Answer: Option (A) is the correct answer.

Explanation:

It is known that elements present in the same group tend to show similar chemical properties because they have same number of valence electrons.

Lithium and sodium are both group 1 elements and each of them have 1 valence electron. Hence, they show similar chemical properties.

Beryllium is a group 2 element and boron is a group 13 element. Hence, they do not show any similar chemical properties.

Carbon is a group 14 element and sulfur is a group 16 element. Hence, they do not show any similar chemical properties.

Hydrogen has only one electron and helium is a noble gas as it has only 2 electrons. Hence, they do not show any similar chemical properties.

Hydrogen shows the properties of both metals and non-metals. Whereas lithium being a metal will show the properties of metals only. Hence, they do not show any similar chemical properties.

Thus, we can conclude that out of the given options lithium and sodium is the pair of elements show similarities in the pattern of chemical bonding.

After pyruvate oxidation, the chemical energy of how many carbons of the original glucose molecule is converted to chemical ener

Mars2501 [29]

I believe the answer is 4 carbons. Glycolysis involves break down of glucose to two molecules of pyruvic acid (3 carbons) under aerobic conditions. At the end of glycolysis the two pyruvate molecules undergoes pyruvate oxidation to capture the remaining energy in the form of ATP. A carboxyl group is removed from pyruvate and released in the form carbon dioxide, leaving a two carbon molecule which forms Acetyl-CoA (2 molecules). Acetyl-CoA then serves as a fuel for the citric acid cycle in the next stage of cellular respiration.

A thermometer with a percent error of 6.5% reads the room temperature as 68°F. what is the actual temperature in the room ?

Lynna [10]

Answer:

Actual temperature for the given temperature with thermometer with error of 6.5% is 63.8 degrees.

Explanation:

The percentage error in thermometer is 6.5% this means that if the temperature is 100 degrees the thermometer shell show 106.5 degrees. now calculating the actual temperature of the thermometer when the given temperature is 68°

Applying unitary method for solution 106.5

Then 100 will be $\frac {68}{106.5} \times 100$

= $0.6384 \times 100$

= 63.8 Degrees

On solving the value of this equation will give the actual temperature as 63.8 Degrees .
