If you measured the temperature of the ocean at increasing depths, will the temperature of the water increase or decrease with d
Viefleur [7K]
In the ocean, solar energy is rapidly absorbed or reflected in the upper surface, leaving little energy to penetrate deeper, and so deeper water is not heated (this also explains the lack of light deep in the ocean). Additionally, warm water is less dense than cold water, and so cold water will sink while warm water floats above it.

Thus, temperature of the ocean also varies from top to bottom, giving a vertical structure to most of the ocean. This vertical structure has a large impact on how life is distributed in the ocean.

Gestalt psychology focuses on _____.
jok3333 [9.3K]

Answer:

the brain's ability to memorize information

Explanation:

Gestalt psychology provides a holistic perception to how the brain tends to deal with information it picks. The belief is that the whole is greater than the individual parts. Gestalt is a German word which means whole.

Psychologists that subscribes to this school of thought believes that the brain generally relates with events by creating a complete perceived view of such. For example, christmas lights are pictured as moving because its easier for the brain to relate with such rythm in that way. This helps the brain memorize a piece better than looking at individual relationship between the parts.

" what is the total positive charge the protons have together ? " how do I tell?? Please help!!!
zzz [600]
To calculate this, the first step is to determine the number of protons in each atom of the ion. You can use their atomic number to find the number of protons. If the number protons and electrons are equal there is no charge, so the next step is to determine how many electrons to add or remove to the number of protons.

2. 10.00 grams of a sample of hydrated PtCl4 are heated and lose 3.00 g of water. How many moles of water are combined with each
In-s [12.5K]

Answer:

8 mol

Explanation:

Step 1: Calculate the mass of PtCl₄ in the sample

10.00 grams of a sample of hydrated PtCl₄ are heated and lose 3.00 g of water. The mass of PtCl₄ is:

mPtCl₄ = 10.00 g - 3.00 g = 7.00 g

Step 2: Calculate the moles corresponding to 7.00 g of PtCl₄ and 3.00 g of H₂O

The molar mass of PtCl₄ is 336.9 g/mol.

7.00 g × 1 mol/336.9 g = 0.0208 mol

The molar mass of H₂O is 18.02 g/mol.

3.00 g × 1 mol/18.02 g = 0.166 mol

The molar ratio of H₂O to PtCl₄ is:

0.166 mol H₂O/0.0208 mol PtCl₄ ≈ 8 mol H₂O/ 1 mol PtCl₄
