Answer 1

Answer:

Yes, that is correct!

Explanation:

Answer 2

Answer:

Yes

Explanation:

A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.

productivity of cellular
respiration?

Answers

Answer: it’s the chemicals between the biological

Explanation:

The productivity of photosynthesis affect the productivity of cellular respiration by providing energy.

What is photosynthesis?

Photosynthesis is a process where plants prepare their food in the presence of sunlight.

Photosynthesis process chemically illustrated as :

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

From the above it is clear that carbohydrate is produced in the photosynthesis process and this carbohydrate provide energy to the plant for the completion of another chemical process. So, for the cellular respiration plants use this energy.

Hence, the productivity of photosynthesis directly affect the productivity of cellular respiration.

The sample of gas is in a container with a fixed volume. A student notices that as the temperature increases so does the
pressure. This is a(n) ___
relationship.
There aren’t any answer choices.

Answers

Answer:

Direct

Explanation:

Edge

When the temperature increases with an increase in pressure, it is a direct relationship.

What is Gay Lussac's law?

Gay-Lussac's law can be described as when the volume of the gas remains constant then the pressure of a gas is directly proportional to the absolute temperature of the gas.

The mathematical equation of Gay Lussca's law is written as follows:

P/T = k

It can be represented as the pressure is directly proportional to the absolute temperature.

P ∝ T               (where 'V' volume of gas is constant)

or

[tex]\frac{P_1}{T_1} =\frac{P_2}{T_2}[/tex]

Where P₁ and T₁ are the initial temperature and pressure while P₂ and T₂ are the final pressure and temperature of the gas.

The sample of gas has a fixed volume of gas and on increasing the temperature the gas molecules acquire more and more kinetic energy. So the pressure of the gas will also increase.

Therefore, there will be a direct relationship between temperature and pressure of gas.

Which statement describes the water gas particles in the air above the cup compared with the water liquid
particles in the cup?
The partides move faster and are closer together
The particles move faster and are far apart
The particles move slower and are closer together
The particles move slower and are far apart

Answers

Answer:

The particles move faster and are far apart

Explanation:

A substance may exist in three states of matter; solid, liquid and gas.

In the solid state, there is very strong intermolecular forces between the particles of the substance. They can only vibrate or rotate about their mean positions but can not translate.

In the liquid state, the particles of the substance have a greater degree of freedom than in the solid. The magnitude of intermolecular forces is lower than in solids, the molecules can move at low speeds.

In a gas, the molecules are separated from each other with negligible intermolecular interaction hence they move at very high speed.

Therefore, for the water gas particles in the air above the cup; the particles move faster and are far apart.

Answers

Answer:

water, H20

Explanation:

From the given choices, only water has two unshared or lone pairs of electrons in its central atom.

The formula of water is:

              H₂O

H is hydrogen with 1 electron

O is oxygen with 8 electrons and 6 valence electrons

To form the covalent bond, the 6 valence electrons are involved. Two out of the 6 bonds with the two oxygen.

The remaining 4 gives the two lone pairs.

Diagram is not a mixture of compounds. It is a single compound in gaseous state .

A compound is a combination of elements in a definite grouping. The properties of the compound is distinct from that of the element that combines to form it. Therefore, since we just a black and yellow circle, the diagram is a compound and nothing more. The other descriptions are perfect.

Many plants in rainforests have leaf tips that come to a point, so precipitation drains off the leaf. This helps to keep the plant safe from harmful germs. Based on this info, what resource is prevalent in a rainforest?

Answers

Answer:

rainfall/water

Explanation:

The possession of drip tips by the leaves of plants in the rainforest is a form of adaptation against high rainfall. Without the drip tips on leaves, water will persist on the surface of leaves, and in conjunction with the warm climate, promotes the growth of pathogens such as fungi and bacteria.

Hence, the possession of drip tips on leaves is an indication of the prevalence of water in the rainforest region.

What is the balanced equation for KOH+CO2—>K2CO3+H2O

Answers

The balanced equation :

2KOH+CO₂⇒K₂CO₃+H₂O

Further explanation

Equalization of chemical reaction equations can be done using variables. Steps in equalizing the reaction equation:

1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c etc.

2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index between reactant and product

3. Select the coefficient of the substance with the most complex chemical formula equal to 1

Reaction

KOH+CO₂⇒K₂CO₃+H₂O

give coeffiecient

aKOH+bCO₂⇒K₂CO₃+cH₂O

make equation

K, left=a, right=2⇒a=2

H, left=a, right=2c⇒a=2c⇒2=2c⇒c=1

O, left=a+2b, right=3+c⇒a+2b=3+c⇒2+2b=3+1⇒2b=2⇒b=1

Once you have drawn your model on a poster board, you will write one to two paragraphs explaining how water is transferred within and between organisms and the environment. Background Information Water is a very important compound. Organisms need water to carry out life-maintaining processes such as growth and development. Without water, living things will not survive. Water continually flows among the atmosphere, land, water, and living organisms. This process, called the water cycle, allows water to be recycled as it moves through Earths spheres. Materials Assignment Instructions Step 1: For this project, you are expected to submit the following: 1. Your model of the water cycle 2. One to two typewritten paragraphs describing the water cycle Step 2: Prepare for the project. a) Read through the guide before you begin so you know the expectations of this project. Pay particular attention to the instructions you need to follow to create a model on your poster board. b) If anything is not clear to you, be sure to ask your teacher. Step 3: Gather materials for the model. a) Start with a blank poster board. Be sure to put your name on it. b) You may either draw the parts of the water cycle or print images to construct a model on your poster board. Gather any drawing tools that you will need, or print any images you want to use. Step 4: Create a model of the water cycle. a) Your model should include bodies of water such as lakes and oceans, organisms, air, and land. b) Draw arrows indicating how water moves within an ecosystem and between organisms and their environment. Be sure to include the Sun and gravity in your model. c) Include short phrases on your poster that summarize what occurs at each stage of the water cycle.
