Answer:

its answer A....that's the answer is

7 \times 10 ^ - 7

Explanation:

The visible light spectrum is the section of the electromagnetic radiation spectrum that is visible to the human eye. Essentially, that equates to the colors the human eye can see. It ranges in wavelength from approximately 400 nanometers (4 x 10 -7 m, which is violet) to 700 nm (7 x 10-7 m, which is red).

A sample of barium nitrate is placed into a jar containing water. The mass of the barium nitrate sample is 27g. Assume the water
34kurt
So we have Barium nitrate with a solubility of 8.7g in 100g water at 20°C.

using that relation
i.e.
8.7g (barium nitrate) =100g (water)
1g barium nitrate = 100/8.7 g water

27g barium nitrate = (100/ 8.7 ) × 27
= 310.34 g

therefore,
you need 310.34g of water is in the jar.

The correct description for an atom of helium would be option C. An atom of helium has its valence electrons in its first energy level, it wouldn't and can't satisfy the Octet rule as it only has 2 electrons, but with 2, it has a full shell, as the first energy level can hold only 2 electrons.

Use Appendix C to choose the solution with the lower pH:0.1MBeCl₂ or 0.1MCaCl₂
musickatia [10]

A lower pH means that there are extra hydrogen ions in the liquid, whereas a higher pH indicates fewer hydrogen ions in the liquid. In simple terms, pH is a scale from 1 to 14 that measures the acidity or alkalinity of a liquid.

The hydrated ion undergoes hydrolysis in solution producing `H3O+ . This occurs because the Be-O bond is very strong and so in the hydrated ion and it  weakens the 0-H bond. Hence, there is a strong tendency to lose protons. For this particular reason, the aqueous solution of `BeCl_2` is acidic in nature.

<h3>Will baking soda decrease pH?</h3>

Baking soda, also regarded as sodium bicarbonate is naturally alkaline, with a pH of 8 When you add baking soda to your pool water, you will increase both the pH and the alkalinity, improving balance and clarity. Many industrial pool merchandise for elevating alkalinity utilize baking soda as their most important active ingredient.
