Explain whether indicator paper or a pH meter has the higher resolution

1 answer:

6 0

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

Explanation:

give this answer brainiest.

<h3> <u>ANSWER</u></h3>

2. Neon, only

<h3><u>EXPLANATION</u></h3>

When Na and F combine they form an electron configuration of 2-8. Na electron configuration is 2-8-1 while F is 2-7, so when they form an ionic bond F will gain Na outermost electron to complete its valence shell due to having a higher negativity. Neon has an electron configuration of 2-8 but argon has 2-8-8.

LenaWriter [7]

Answer:

6.49g

Explanation:

Let's consider the balanced reaction for photosynthesis.

6 CO₂ + 6 H₂O = C₆H₁₂O₆ + 6 O₂

We can establish the following relations:

1 mole of CO₂ has a mass of 44.01 g (MW 44.01)
The molar ratio of CO₂ to C₆H₁₂O₆ is 6:1.
1 mole of C₆H₁₂O₆ has a mass of 180.16 g/mol.

The mass of glucose produced by the reaction of 9.51 g of carbon dioxide is:

$9.51gCO_2 \times \frac{1molCO_2}{44.01gCO_2} \times \frac{1molGlucose}{6molCO_2} \times \frac{180.16gGlucose}{1molGlucose} = 6.49g Glucose$
