Answer:

The order is: electron, carbon, water, glucose, glycogen.

Explanation:

The electron is a negatively charged subatomic particle and is therefore the smallest.

Carbon is a chemical element, which belongs to the group-14 of periodic table and has atomic number 6.

Water is a odorless, almost colorless and tasteless chemical compound which is necessary for all the known living form. The chemical formula is H2O and it is composed of 2 hydrogen atoms and one oxygen atom.

Glucose is a monosaccharide sugar and a type of simple carbohydrate. The chemical formula is C6H12O6 and is composed of 6 carbon atoms, 6 oxygen atoms and 12 hydrogen atoms.

Glycogen is a branched polysaccharide molecule, which is composed of multiple monomeric glucose units. Therefore, it is the largest.

Therefore, the increasing order is: electron, carbon, water, glucose, glycogen.

Suppose an adult is encased in a thermally insulating barrier so that all the heat evolved by metabolism of foodstuffs is retain

mihalych1998 [28]

Given:
Q = 9.4 kJ/(kg-h), the heat production rate
c = 4.18 J/(g-K), the heat capacity
t = 2.5 h, amount of time

Note that
c = 4.18 J/(g-K) = 4180 J/(kg-K) = 4.18 kJ/kg-K)

Consider 1 kg of mass.
Then
Qt = cΔT
where ΔT is the increase in temperature (°K)
(1 kg)*(9.4 kJ/(kg-h))*(2.5 h) = (1 kg)*(4.18 kJ/(kg-K))*(ΔT K)
23.5 = 4.18 ΔT
ΔT = 23.5/4.18 = 5.622 K = 5.622 °C

Answer: 5.62 K (or 5.62 °C)

Which of the following is not an example of a polymer? (2 points)

ahrayia [7]

Answer is "sucrose".

Polymer is a large molecule which is made from repeating units. The smallest repeating unit is called as monomer. Polystyrene, nylon and PVC are examples for polymers. But sucrose is a disaccharide which is made from glucose and fructose. Hence, sucrose is not an example of polymer.

He then takes a powerful magnet and positions it below the table and the keys. He finds that he is able to drag the keys along t

Mamont248 [21]

C. magnetic forces act at a distance

Explanation:

Since he was able to drag the keys along the table by moving the magnet, it shows that magnetic forces acts a distance.

Magnetism is a property exhibited by a wide range of materials.

Around a bar magnet, there are field forces in which the forces of the magnets are felt.

Magnetic forces are non- contact forces. They don't need to be together to exert their force.
This is why magnetic forces act at a distance.

What is the chemical equation from table salt made from baking soda

bagirrra123 [75]

NaHCO₃ + HCl → NaCl + H₂O + CO₂

Explanation:

NaHCO₃ + HCl → NaCl + H₂O + CO₂

When Sodium bi carbonate (NaHCO₃) reacts with hydrochloric acid (HCl), it forms table salt (NaCl), water ( H₂O ) and Carbon di oxide (CO₂) gas is evolved.

Here base reacts with acid to form salt and it is the neutralization reaction.
