Other sugars with the same chemical formula as Glucose:

Sugar Formula Description

Glucose C₆H₁₂O₆ It's the most abundant monosaccharide.

Mannose C₆H₁₂O₆ It's found in plants and some animals.

Fructose C₆H₁₂O₆ It's the sugar of fruits.

Galactose C₆H₁₂O₆ It's found in milk.

If the atomic mass is 14 and the atomic number is 7,how many neutrons do you have?

Nitella [24]

Answer: 7 neutrons

Explanation: Atomic number refers to the number of protons in the nucleus of the atom. Also you can treat atomic mass as how many particles (protons and neutrons) are in the nucleus of the atom. So for this problem:

14 particles - 7 protons = 7 neutrons (and we know all that's left over is neutrons because we subtracted all the protons)

Benzoic acid is in the process of being recrystallized. Your lab partner is in a hurry and after the impure benzoic acid is diss

bazaltina [42]

Answer:

Impurities will be trapped in the crystals of the benzoic acid crystallized in this manner.

Explanation:

After benzoic acid is dissolved in hot water, it should have been allowed to cool gradually before it is transferred into an ice bath.

This gradual cooling will aid the separation of impurities so that when the vessel is now submerged in an ice bath, only pure benzoic acid is recrystalized.

If the vessel is immediately submerged into an ice bath, impurities will be trapped in the crystals of the benzoic acid.

_______________ are filled with special absorbing elements that move up and down between the uranium rods to keep the atoms from

d1i1m1o1n [39]

Answer:

The correct answer is - control rods.

Explanation:

Control rods are filled with special absorbing agents such as boron, cadmium, silver, and others to absorb as many neutrons as to control the fission reaction by moving them up and down in between uranium rods.

These control rods are used to prevent the nuclear reaction from getting out of control in the nuclear plant or reactor by absorbing the neutrons and prevent uranium to convert.

How would the pH value of an aqueous solution change, when the hydronium ion concentration is increased by a factor of 10?

Anna71 [15]

Answer:

Increasing H⁺ by 10x => pH decreases by 1 unit

Explanation:

In general, adding H⁺ ions to any aqueous solution ALWAYS causes pH values to fall ( decrease ). Just as adding OH⁻ ions to an aqueous solution causes pH values to rise ( increase ).

Here's a simple calculation demonstrating this...

Given 0.01M HCl(aq) => 0.01M H⁺(aq) + Cl⁻(aq) => pH = -log(0.01) = 2.00

Increase [H⁺] by 10x => 0.10M H⁺(aq) => pH = -log[H⁺] = -log(0.10) = 1.00

Solution with higher H⁺ concentration shows pH decreasing by 1 unit.

______________________________________________________-

Just to support the above statement about adding OH⁻ ions showing an increase in pH values, the following is also provided FYI ..

Given 0.01M NaOH(aq) => 0.01M OH⁻(aq) + Na⁺(aq) => pOH = -log(0.01) = 2.00 => pH = 14 - pOH = 14 - 2 = 12

Increase [OH⁻] by 10x => 0.10M OH⁻(aq) => pOH = -log[OH⁻] = -log(0.10) = 1.00 => pH = 14 - pOH = 14 - 1 = 13

Increasing [OH⁻] by 10x => increasing pH by 1 unit.

Solution with higher H⁺ concentration shows pH decreasing by 1 unit.

______________________________________________________

Remember, for any aqueous solution ...

=> Adding H⁺ => always decreases pH

=> Adding OH⁻ => always increases pH
