Answer:

<em>solid, liquid, and gas.</em>

Explanation:

The <u>three states of matter</u> are the three distinct <u>physical forms</u> that matter can take in most environments: solid, liquid, and gas. In extreme environments, other states may be present, such as plasma, Bose-Einstein condensates, and neutron stars.

Tris(hydroxymethyl)aminomethane, known as TRIS or THAM, is a water-soluble base used in synthesizing surfactants and pharmaceuti

valentina_108 [34]

Tris (as a pure compound normally supplied) is a base and its aqueous solutions are alcaline. It is not a buffer sensu stricto. To accumulate a buffering ability it sould be in equilibrium with the corresponding acid which is the protonated structure of Tris.

<h3>Is Tris damaging to humans?</h3>

The following acute (short-term) fitness consequences can also occur straight away or rapidly after publicity to Tris (2,3- Dibromopropyl) Phosphate: * Contact can irritate the pores and skin and eyes. * Tris (2,3-Dibromopropyl) Phosphate is a PROBABLE CARCINOGEN in humans.

<h3>Is Tris base toxic?</h3>

tris(hydroxymethyl)aminomethane

Potential Adverse human fitness effects and signs : Practically non-toxic. Non-toxic if swallowed (LD50 oral, rat > 5000 mg/kg). Non-toxic in contact with skin (LD50 skin> 5000 mg/kg). Not irritant to skin.

According to the oxygen-hemoglobin dissociation curve, PO2 in the lungs of 100 mm Hg results in Hb being 98% saturated. At high

Ad libitum [116K]

Answer:

Hb would be 78.4% saturated.

Explanation:

This problem can be solved by using simple unitary method.

At 100 mm Hg pressure of oxygen, Hb is saturated by 98%

So, at 1 mm Hg pressure of oxygen, Hb is saturated by $\frac{98}{100}$ %

Hence, at 80 mm Hg pressure of oxygen, Hb is saturated by $\frac{98\times 80}{100}$ % or 78.4%

Therefore, at 80 mm Hg pressure of oxygen in the lungs, Hb would be 78.4% saturated.

Calculate the number of moles of Californium represented by 5.92 x 1024 atoms of Californium. Enter your answer in the provided

Fed [463]

Answer:

9.834 moles Cf.

Explanation:

The number of moles of a substance is an easy way to represents its amount. Avogadro has determined that the total amount in 1 mol is equal to 6.02x10²³(Avgadros' number), so 1 mol has 6.02x10²³ atoms, molecules, ions, or what we are measuring. So:

1 mol of Cf -------------------- 6.02x10²³ atoms

x -------------------- 5.92x10²⁴

By a simple direct three rule:

6.02x10²³x = 5.92x10²⁴

x = 5.92x10²⁴/6.02x10²³

x = 9.834 moles Cf
