Answer:

Although higher resolution does not necessarily mean higher precision, pH meters generally have higher precision than pH strips. ... As with precision, test strips have less potential to be accurate compared with pH meters because of their relatively low resolution

What evidence do you have that tpgs-750m increases the reaction rate? How does tpgs-750m act to increase the reaction rate?
notka56 [123]

TPGS-750 M conducts reaction under lower temperature then the reactions carried out in organic solvents.

<h3>What is tpgs-750m ?</h3>

It is a chemical molecule of the second generation known as an amphiphile, with both hydrophilic and lipophilic qualities.

  • In contrast to any other organic solvent, water is used for transition metal catalysed cross-coupling, making TPGS-750M a second generation surfactant with physical features that encourage this process.

  • The hydrophilic portion of TPGS-750M, which is utilised in medicine, is made of Poly(ethylene glycol), and the hydrophobic portion is made of the vitamin E compound alpha-tocopherol.

Give three examples of energy traveling in waves
mrs_skeptik [129]

Answer:

ELECTROMAGNETIC SPECTRUM. Radios, televisions, mobile phones, and radar use signals made up of electromagnetic waves. These are waves that carry energy as electricity and magnetism at the speed of light. Light we can see is also an electromagnetic wave, but other types of electromagnetic wave are invisible.

`Suppose you have a sample of NaOH (0.0315 L, to be exact). If this amount of NaOH is used to exactly titrate 0.0250 L of HCl th
yuradex [85]

Answer:

0.0835 M

Explanation:

Step 1: Write the balanced equation

NaOH + HCl ⇒ NaCl + H₂O

Step 2: Calculate the reacting moles of HCl

0.0250 L of 0.105 M HCl react.

0.0250 L × 0.105 mol/L = 2.63 × 10⁻³ mol

Step 3: Calculate the reacting moles of NaOH

The molar ratio of NaOH to HCl is 1:1. The reacting moles of NaOH are 1/1 × 2.63 × 10⁻³ mol = 2.63 × 10⁻³ mol.

Step 4: Calculate the molarity of NaOH

2.63 × 10⁻³ moles of NaOH are in 0.0315 L of solution.

M = 2.63 × 10⁻³ mol / 0.0315 L = 0.0835 M
