Answer:

I, II, III,IV

Explanation:

Metals are known to possess metallic bonds. In a metallic bond, electro-positive metals loose electrons which form a cloud of electrons which exerts an attractive force on the positive metallic ions. This attractive force holds the metal atoms together in the crystal lattice.

The physical properties of metals include;

I. thermal conductivity

II. electrical conductivity

III. malleability

IV. ductility

Hence, substances that exhibit properties I-IV are metals and have metallic bonds.

The following properties which a substance that has metallic bonding

normally have include

Metals are elements which have metallic bonding which is always strong as

it helps to form a lattice.

Metals are good conductors of heat and electric current , they can also be

bent in to different shapes . This means it has all the properties listed above.

Explanation:

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

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.

Sodium hydroxide, with the formula NaOH, is usually used in products as a pH adjuster. It's also used in soap-making to turn fats and oils into soap. You can find sodium hydroxide (also called caustic soda or lye) in its pure form in the cleaning aisle, since it's also really handy for clearing up clogged drains.

Answer:

Boiling water- When water boils, the heat passes from the burner into the pot, heating the water at the bottom. This hot water rises and cooler water moves down to replace it, causing a circular motion. ... ice melting - Ice melts because heat moves to the ice from the air.

Craters on the Moon are caused by asteroids and meteorites colliding with the lunar surface. The Moon's surface is covered with thousands of craters. ... It also has very little geologic activity (like volcanoes) or weathering (from wind or rain) so craters remain intact from billions of years.

Mass of H₂SO₄ : 69,972 g

A mole is a number of particles(atoms, molecules, ions)  in a substance

This refers to the atomic total of the 12 gr C-12  which is equal to 6.02.10²³, so 1 mole = 6.02.10²³ particles  

Can be formulated :

N = n x No

N = number of particles

n = mol

No = 6.02.10²³ = Avogadro's number

moles of H₂SO₄ :

[tex]\tt mol=\dfrac{N}{No}\\\\mol=\dfrac{4.3\times 10^{26}}{6.02\times 10^{23}}\\\\mol=7.14\times 10^2[/tex]

mass H₂SO₄ (MW=98 g/mol) :

[tex]\tt mass=mol\times MW\\\\mass=7.14.10^2\times 98\\\\mass=69,972~g[/tex]

Answer:

The substances present after the reaction are called products.

Explanation.

They are called reactants at the start of the reaction.

Answer:

In the first law, an object will not change its motion unless a force acts on it

In the second law, the force on an object is equal to its mass times its acceleration

In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

Answer:

[tex]V=0.001\ m^3[/tex]

Explanation:

Mass, m = 1 kg

The density of water, d = 1000 kg/m³

We need to find the volume of water. The formula for the density of an object is equal to mass divided by volume. Its formula is :

d = m/V

V is the volume of water

[tex]V=\dfrac{m}{d}\\\\V=\dfrac{1\ kg}{1000\ kg/m^3}\\\\=0.001\ m^3[/tex]

So, the volume of water is [tex]0.001\ m^3[/tex].

Answer:

Volume of water has a mass of 1 kg  is explained below in details.

Explanation:

One liter of h2O has a volume of approximately specifically one kilogram when estimated at its maximum frequency, which happens at about 4 °C. It observes, therefore, that thousand of a liter, recognized as one milliliter (1 mL), of h2O has a volume of about 1 g; 1000 liters of h2O has a volume of about 1000 kg (1 tonne).

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.

Answer:

Moles of oxygen molecules produced = 3 mol

Explanation:

Given data:

Moles of oxygen molecules produced = ?

Number of moles of lead oxide decomposed = 6 mol

Solution:

Chemical equation:

2PbO₂          →        2PbO + O₂

Now we will compare the moles of oxygen and lead oxide.

                   PbO₂        :          O₂

                      2           :            1

                      6           :           1/2×6 =3 mol

three moles of oxygen molecules are produced.

Answer:

No

I dont at least but you may be lucky

We will use dimensional analysis to solve this.

We will need to know Avogadro's number, which is 6.02 × 10²³.

4.5 mol × [tex]\frac{6.02 * 10^{23} molecules}{1 mol}[/tex] = 2.71 × 10²⁴ molecules.

There are 2.71 × 10²⁴ molecules in 4.5 moles of Ca(OH).
