Adding solvent or removing solute from a soltuion is called , and a solution is said to be _____ if it has more solute.

Answers

Answer 1

Answer: Adding solvent or removing solute from a solution is called diluting. And a solution is said to be concentrated if it has more solute. The opposite of diluting is called concentrating. The measure of the amount of solute in a solution is expressed in concentration.

Light can penetrate to only a depth of between 50 and 100 m in most ocean water. what effect does tsh have on the water's oxygen concentration?explain

Answers

This means that waters at these depths will have a higher concentration of oxygen than deeper waters where the light rays cannot reach. This is because phytoplantons will be found in photic zones in the oceans. Therefore, these photosythetic organisms produce oxygen as a byproduct of photosythesis and use up carbon dioxide.

Light penetration plays a crucial role in the oxygen concentration in the ocean. Light can penetrate up to 50 to 100 meters of the ocean water, leaving high concentration of oxygen at ocean's depth.

The deep oceans are high in the concentration of oxygen. The rates of consumption of oxygen at such depth are low. The phytoplanktons are found in the photic zones of oceans, where these organisms perform photosynthesis. Phytoplanktons are not observed in the deep layers of ocean, therefore, the oxygen consumption will be low. The photosynthetic organisms yield oxygen as a by product, and use up carbon dioxide.

Therefore, the oxygen concentration at deep ocean levels will be higher.

Suppose a laboratory has a 31 g sample of polonium-210. The half-life of polonium-210 is about 138 days. How many half-lives of polonium-210 occur in 966 days? How much polonium is in the sample 966 days later?

Answers

The answer is a) 7 half-lives and b) 0.78% (or as fraction 1/128) of the starting amount.

a) If half-life of Polonium-210 is 138 days, to calculate how many half-lives occur in 966 days, we will simply divide them: 966/138 = 7
So, 7 half-lives occur in 966 days.

b) To calculate the remaining amount, we will use the formula:
$(1/2)^(n) =x$
where n is the number of half-lives, and x is the remaining amount in decimals, and (1/2) is half-life.

We've already found that n = 7, so replace it in the formula:
$(1/2)^(7) =0.0078 =$ 0.78% = 1/128

Answer : The amount of polonium in the sample 966 days later is, 0.24 g

Solution :

Polonium-210 is a radioactive element.

Formula used :

$N(t)=N_o* ((1)/(2))^{(t)/(t_(1/2))$

where,

$N(t)$ = the amount of polonium-210 remaining after 't' days

$N_o$ = the initial amount of polonium-210 = 31 g

t = time = 966 days

$t_(1/2)$ = half-life of the polonium-210 = 138 days

Now put all the given values in the above formula, we get

$N(t)=(31g)* ((1)/(2))^{(966)/(138)}$

$N(t)=0.24g$

Therefore, the amount of polonium in the sample 966 days later is, 0.24 g

Photosynthesis transfers carbonfrom the nonliving environment to the living environment.
from the cell to the air.
from the water to the cell.
from the nucleus to the mitochondria.

Answers

Photosynthesis is the process in plants to make their food. This involves the use carbon dioxide to react with water and make sugar or glucose as the main product and oxygen as a by-product. I think the best answer would be the first statement.

Answer: Option A

Explanation:

Photosynthesis is a process that helps the plants to make food by the help of carbon dioxide from the atmosphere and water, nutrients from soil and converts it into glucose in the presence of sunlight.

Atmosphere is a non living component of environment where carbon dioxide is present and it is transferred to plants which is a living component of ecosystem.

At atom that has only one electron in its valence electron shell is ________ chemically reactive.a. not
b. mildly
c. highly
d. The name of the element is needed to figure this out.

Answers

The correct answer is C. An atom having only one valence electron is highly chemically reactive. The valence electron says a lot to the reactivity of an atom. For example, sodium has only one valence electron which makes it so reactive and unstable. The alkali metals have only 1 valence electron.

Answer:The correct answer is C. Highly

Explanation:

its correct because I got it correct on my test sooo..yuup.!
