Answer:

The equation for photosynthesis is 6 CO2 + 6 H2O + light --> C6H12O6 + 6 O2, so carbon dioxide will be found in the reactant part of the equation.

Answer: a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.

A hypothesis is used in an experiment to define the relationship between two variables. The purpose of a hypothesis is to find the answer to a question. A formalized hypothesis will force us to think about what results we should look for in an experiment. The first variable is called the independent variable

Answer:

heat I think.....

During a change in state, energy is transferred in the form of heat.

Hence, Option (A) is correct.

When energy is added or removed to matter in the form of heat, it changes state to form a state of matter.

A state of matter is defined as one of the ways in which matter can interact with itself to form a homogeneous phase.

Therefore , During a change in state, energy is transferred in the form

of heat. Hence, Option (A) is correct.

Answer:

Average atomic mass of moorium is 39.844 amu.

Explanation:

Given data:

Atomic mass of moorium-36 = 35.978 amu

Relative abundance of  moorium-36 = 1.32%

Atomic mass of moorium-38 = 37.963 amu

Relative abundance of  moorium-38 = 3.25%

Atomic mass of moorium-40 = 39.962 amu

Relative abundance of  moorium-38 = 95.43%

Solution:

Average atomic mass moorium = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass)+ (abundance of 3rd isotope × its atomic mass)  / 100

Average atomic mass of moorium = (1.32×35.978)+(3.25×37.963)+(95.43×39.962) /100

Average atomic mass of moorium =  47.491 + 123.380 +3813.574  / 100

Average atomic mass of moorium = 3984.445 / 100

Average atomic mass of moorium = 39.844 amu

Answer:

53.11× 10²³ molecules

Explanation:

Given data:

Number of molecules of CO₂ = ?

Mass of CO₂ = 388.1 g

Solution:

Formula:

Number of moles = mass/ molar mass

Molar mass of CO₂ = 12× 1 + 16×2

Molar mass of CO₂ = 44 g/mol

Now we will put the values in formula.

Number of moles = 388.1 g/ 44 g/mol

Number of moles = 8.82 moles

Now we will calculate the number of molecules by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ molecules

8.82 mol × 6.022 × 10²³ molecules / 1 mol

53.11× 10²³ molecules

Brainliest plz?

Answer:

Now times by Abogadros constant: 1* 6.022*10^23=6.022*10^23 molecules of CO2 are present.

Explanation:

We know the molar mass of CO2(g) is 44.01⋅g⋅mol−1 . And so Avogadro's number of carbon dioxide molecules have this mass... And we take the product of the quotient... Molecules of carbon dioxide=5.00⋅mol×6.022×1023⋅mol−1≅30×1023⋅carbon dioxide molecules.

Answer:

Explanation:

ΔG  =  Δ H - T ΔS

Given , ΔG = -237.2 kJ / mol

Δ H = - 285.8 kJ / mol

T = 298

Putting the values in the equation

-237.2 = - 285.8 - 298 x ΔS

ΔS  = .163 kJ / mole K

moles of water formed = 4.31 / 2 = 2.155

entropy change required = 2.155 x .163 kJ / K

= 351.26 J / K .

Answer: A Meteor

Explanation:

A streak of light in the sky and says she is seeing a shooting star. She's most likely observing is a meteor. Therefore, option C is correct.

A meteor is an object from space or a meteoroid that touches down on Earth. The air on the space rock creates drag that causes it to become incredibly heated as it falls toward Earth.

When the earth travels through cometary debris during its orbit around the Sun, meteor showers will result. Although the Earth's orbit around the Sun is nearly round, the majority of comets have very elliptical orbits.

A meteoroid becomes a meteor, or a streak of light in the sky, if it gets close enough to Earth and enters its atmosphere. These light striations are sometimes referred to as "shooting stars" due to their appearance. However, stars are not what meteors are.

Thus, option C is correct.
