Answer:

false it removes carbon dioxide                         ......The heart pumps blood to all parts of the body. Blood provides oxygen and nutrients to the body and removes carbon dioxide and wastes. As blood travels through the body, oxygen is used up,

Explanation:

Oxygenated blood travels from the lungs through the pulmonary veins and into the left side of the heart, which pumps the blood to the rest of the body (see Function of the Heart). ... Then the blood is pumped through the pulmonary artery to the lungs, where it picks up oxygen and releases carbon dioxide.

Answer:

true because your heart contains blood that flows through you body system

In an ecosystem, deep, cold water is the  densest while warm, shallow water is the  least dense.

An ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the ecosystem through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Answer:

yes

Explanation:

the energy released in the synthesis of water is equal to the energy absorbed in the decomposition of water. This outcome happens because the difference in energy between the reactants and the products in both cases is equal. . It follows the law of conservation of energy.

Answer:

Potassium

Explanation:

The atom with the largest atomic radius is potassium from the given list.

The atomic radius is taken as half of the inter-nuclear distance between two covalently bonded atoms of non-metallic elements or half of the distance between nuclei in the solid metal state.

Across a period in the periodic table, atomic radii decreases progressively from left to right.

This is due to the progressive increase in the nuclear charge without an attendant increase in the number of electronic shells.

Answer:

Potassium

Explanation:

An atom's size is defined by the distance from the nucleus to the valence (outer) shell of electrons. Although difficult to to actually measure, due to electrons existing in a probability field with no defined boundaries, it is common knowledge that the more valence shells of an atom, the larger the atom.

Knowing this, lets look at the electron configuration of the elements mentioned:Oxygen = 2,6Sodium = 2,8,1Magnesium = 2,8,2Potassium = 2,8,8,2As we can see, only Potassium has four electron shells, therefore Potassium has the largest atomic size.Alternatively, one can look at a Van der Waal radii table to find that the radii of the four elements are (in picometres):Oxygen = 152 pmSodium = 227 pmMagnesium = 173 pm

Showing once again how Potassium has the largest atomic radius, and therefore the largest atomic size. Interestingly enough, Sodium has a larger atomic radius then magnesium, despite having less electrons and protons.

Answer:

68.95moles

Explanation:

Given parameters:

Number of particles of lithium  = 4.151 x 10²⁵ particles

Unknown:

Number of moles  = ?

Solution:

From the mole concepts, we know that;

         6.02 x 10²³ particles are contained in 1 mole of a substance

          4.151 x 10²⁵ particles contains [tex]\frac{4.151 x 10^{25} }{6.02 x 10^{23} }[/tex]    = 68.95moles

Answer:

c

Explanation:

The number of atoms : N = 2.709 x 10⁴⁶

Given

4.5 x 10²² moles of CO₂

Required

The number of atoms

Solution

The mole is the number of particles(molecules, atoms, ions) contained in a substance  

1 mol = 6.02.10²³ particles

Can be formulated

N=n x No

N = number of particles

n = mol

No = Avogadro's = 6.02.10²³

Input the value :

N = 4.5 x 10²² x 6.02 x 10²³

N = 2.709 x 10⁴⁶

Answer:

[tex]\boxed {\boxed {\sf A. \ 54 \ grams }}[/tex]

Explanation:

To convert from moles to grams, we must use the molar mass.

Recall that water's molecular formula is H₂O. It contains hydrogen and oxygen. Look up the two elements masses on the Periodic Table.

Now, use these masses to find water's mass. The subscript of 2 tells us there are 2 atoms of hydrogen, so we multiply hydrogen's mass by 2 and add oxygen's.

Use the molar mass as a ratio.

[tex]\frac{18.015 \ g \ H_2 O}{ 1 \ mol \ H_2 O}[/tex]

Multiply by the given number of moles.

[tex]3 \ mol \ H_2O*\frac{18.015 \ g \ H_2 O}{ 1 \ mol \ H_2 O}[/tex]

The moles of water will cancel.

[tex]3 *\frac{18.015 \ g \ H_2 O}{ 1 }[/tex]

[tex]3 *{18.015 \ g \ H_2 O}[/tex]

[tex]54.045 \ g \ H_2O[/tex]

Round to the nearest whole number. The 0 in the tenth place tells us to leave the number as is.

[tex]54 \ g \ H_2O[/tex]

There are about 54 grams of water in 3 moles.

Answer:

54 grams

Explanation:

First step is to find what one mole of water is in grams.

Water is H2O so that means we have two moles of Hydrogen.

H - 2 grams (on periodic table)

We have one mole of Oxygen.

O - 16 grams (on periodic table)

Add 2 and 16 to get 18 total grams in one molecule of H2O

Now multiply 3 times 18 to know how many grams in 3 moles of H2O

You end with

3x18=54 grams

There is honestly no right answer for this but here is what I would put:

Atomic mass increases as you go from left to right. If you look at the periodic table, it would be between Sn and Sb. It would bet here because Sn is 118 and Sb is 121. Basing it off of Antimony and putting it in group 15, the properties are that it is metallic and is a poor conductor of heat. I would call it Stin, which would be shortened to St.

Explanation:

Answer:

An orbit is a fixed path around the nucleus where an electron must be found; an orbital is a probability region where an electron is likely (but

not necessarily) going to be found

Explanation:

Orbits are fixed elliptical paths where an electron must be found. The idea of orbits was introduced in the Bohr model of the atom. Electrons were shown to occupy fixed orbitals of quantized energy.

Orbital is an idea introduced by quantum mechanics. It refers to a region in space where an electron may be found. The wave mechanical approach does not view the electron as being found in a fixed orbital but rather defines a region in space around the nucleus where there is a high probability of finding the electron.

Answer:

3 moles of carbon atoms is equivalent to 36 gm carbon.

In 12gm carbon there are 6.023*10^23 atoms.

So in 36 gm there are 3*6.023*10^23 atoms.

so the answer is 18.069*10^23 atoms.
