Which element in the second period has the largest atomic radius? a potassium (K) b neon (Ne) c carbon (C) d lithium (Li)

Answers

Answer 1

Answer: The element in the second period that has the largest atomic radius is the Lithium (Li). The answer is letter D. As you go down the periodic table, the atomic radius increases and as you go across the periodic table, the atomic radius decreases.

Answer 2

Answer:

Answer:

d lithium (Li)

The temperature at which a liquid becomes a solid is the:A. Boiling point
B. Density
C. Freezing point
D. Solubility

Answers

The point where a liquid becomes a solid is its freezing point. The freezing point of water, for example, is 0°C, at which point it turns to ice.

The answer is Freezing point Because It would be 0 degrees Celsius is it freezing point.

If two gases are present in a container, the total pressure in the container is equal toa.the sum of the pressures that are exerted by each of the two gases.
b.twice the sum of the pressures that are exerted by the individual gases.
c.the sum of the pressures that each gas would exert if they occupied twice the volume.
d.the sum of the pressures that each gas would exert if they occupied half the volume.

Answers

Answer: The correct option is (a).

Explanation:

If two gases are present in a container, the total pressure in the container is equal to the sum of the all the individual pressures exerted by the individual gases in a container.

Individual pressure exerted by the individual gas in a container is called partial pressure of that individual gas.

So, total pressure of gas in container is:

$p^o=p_a+p_b$

Where $p^o$ = Total pressure exerted by the gases in the container.

$p_a$ = Partial pressure of gas 'a'

$p_b$ = partial pressure of gas 'b'

The answer is a, because the question is referring to partial pressures. Partial pressures are a mere sum, no halving or doubling of anything is necessary.

So, A

Enzymes are proteins that speed up chemical reactions in the body how do they workA. they increase the surface area of reactants
B.they increase the concentration of reactants
C.they decrease the concentration of products
D. They act as reactants

Answers

The answer would be D, Enzymes are soluble protein molecules that can speed up chemical reactions in cells. These reactions include respiration, photosynthesis and making new proteins. For this reason enzymes are sometimes called biological catalysts.

Answer:

D) They act as reactants

Explanation:

Becky is a flower gardener. Her plants need a rich soil, full of nutrients, to grow. Propose a detailed plan of how Becky can determine if her soils are fit for growing flowers

Answers

Answer:

In order to grow a plant one should first look and compare the climate of the local environment in which the plant grows with the climate in which the person is planning to grow the plant. Thus, in the given case, Becky should do more examinations on the kind of environment and the kind of soil in which the flower is grown generally. By finding the kind of soil, one should perform some brisk assessment on the structure and composition of the soils that will permit one to find that whether or not the planting location is suitable for the growth of the flower.

For the answer to the question above, Becky should consider the climate of the native environment in which the plant is found then compare it the to the climate in which she plans on growing the flowers, similar climates will produce some similarities between soils. She should research on what type of environment the plant was suitable. Because like strawberries can't be grown on desert temperature and soil.
