Answer:

[tex]\Large \boxed{\mathrm{\bold{A.} \ Group \ 1}}[/tex]

Explanation:

In covalent bonding, atoms share electrons from their last shell to other atoms to gain stability.

Chlorine has 7 electrons in its last shell, it needs to gain 1 electron to become stable.

Group 1 elements have 1 electron in their last shell, they need to lose 1 electron to become stable.

Group 1 elements can bond with chlorine.

Answer:

m = 42.24 grams

Explanation:

Given that,

The density of the mass of a rock is 3.52 g/cm³.

Initial volume of the graduated cylinder is 50 mL and when rock is put in it the water level makes the level rise to 62 mL.

We need to find the mass of the rock.

Volume of rock = final volume - initial volume

Volume of rock = 62 mL - 50 mL

Volume of rock = 12 mL

1 ml = 1 cm³

So, 12 mL = 12 cm³

Density=mass/volume

[tex]m=d\times V\\\\m=3.52\ g/cm^3\times 12\ cm^3\\\\m=42.24\ g[/tex]

So, the mass of the rock is 42.24 grams.

The mass of the rock is 42.24 g

We'll begin by calculating the the volume of the rock.

Volume of rock = (Volume of water + rock) – (Volume of water)

Volume of rock = 62 – 50

Volume of rock = 12 mL

Finally, we shall determine the mass of the rock.

Mass of rock =?

Mass = Density × Volume

Mass of rock = 3.52 × 12

Mass of rock = 42.24 g

Answer:

22.5

Explanation:

M=D*V

V=5*5*5=125

M=0.180*125= 22.5

The mass of the liquid is 22.5 g.

A cubic container has a side length (l) of 5.00 cm. We can find the volume of the cube occupied by the liquid using the following expression.

[tex]V = l^{3} =(5.00cm)^{3} =125 cm^{3}[/tex]

We have 125 cm³ of a liquid with a density of 0.180 g/cm³. The mass of the liquid is:

[tex]125 cm^{3} \times \frac{0.180g}{cm^{3} } = 22.5 g[/tex]

The mass of the liquid is 22.5 g.

Answer:

The answer is 60300000

Explanation:

The standard notation is the counterpart of the scientific notation, while the scientific notation tries to make the number smaller by using exponential numbers with base 10, the standard notation leaves them as whole numbers or decimal numbers.

Example: 5x10∧3 is written in standard notation as 5000; Where 3 tells us the amount of 0 that follows the whole number.

2.05x10∧2 is = 205 in standard notation; Where the 2 tells us the number of times the comma is moved to the right.

Explanation:

Matter are anything that is made up of atoms. The quantity of matter can be observed only on the basis of mass and volume calculation. Therefore, rock, air and water all are matter.

Matter is a substance that has some mass and can occupy some volume. The matter is mainly used in science. Matter can be solid, liquid or gas.

Matter is anything that is made up of atoms. Anything around us that can be physically seen and touched are matter. Ice, water and water vapors are example of matter.

So as we saw that matter has some mass so mass can be measured in gram only. Mass can also be represented as number of molecules. We also saw that matter occupy some volume and that volume is measured only in liter. Rock, air and water all are matter.

Therefore, rock, air and water all are matter.

Answer:

2.32 liters

Explanation:

you would just divide 24 by 3 which is 8 and multiply 290 by it which is 2320 and divide by 1000 which is 2.32

The quantity of milk that will the lamb give in 24 hours is 2.32 Liter.

Lamb may be defined as the youngest form of sheep. In other words, it may be characterized as the little offspring produced by a sheep.

According to the question,

The amount of milk given by lamb in three hours = 290 milliliters.

∴ The amount of milk given by lamb in one hour = 96.66 milliliters.

Now, the amount of milk given by a lamb in 24 hours = 24 × 96.66 = 2320 milliliters.

Now, as per the requirement of the question, convert milliliter into liter.

One liter = 1000 milliliters.

∴2320 milliliters = 2320/1000 = 2.32 liters.

Therefore, the quantity of milk that will the lamb give in 24 hours is 2.32 Liter.

New experimental methods

Technological inventions

Explanation:

A scientific theory is usually not based on speculation. Scientific theories must have a solid empirical basis.

However, experimental methods are limited to the caliber of equipments available at the time in which a theory is formulated. With advancing years, more technological sophistication leads to the invention of new instruments and ultimately, the development of new experimental methods.

These innovations are likely to alter existing scientific theories as new evidences emerge, hence the answer.

Answer:

The volume of water vapor produced at STP is 11.60 L.

Explanation:

The decomposition reaction of H₂O₂ is:

2H₂O₂ → O₂ + 2H₂O     (1)

We have:

m(H₂O₂): mass = 17.0 g

M(H₂O₂): molar mass = 34 g/mol    

To find the volume of water vapor produced we need to find first the number of moles of H₂O₂ and H₂O:

[tex] n_{H_{2}O_{2}} = \frac{m}{M} = \frac{17.0 g}{34 g/mol} = 0.5 moles [/tex]

From the reaction (1) we have that 2 moles of H₂O₂ produce 2 moles of H₂O, so the number of moles of H₂O is:

[tex] 2n_{H_{2}O_{2}} = 2n_{H_{2}O} \rightarrow n_{H_{2}O} = 0.5 moles [/tex]

Now, we can find the volume of water vapor produced at STP, using Ideal gas law:

[tex] V = \frac{nRT}{P} = \frac{0.5 moles*0.085 L*atm/K*mol*273 K}{1 atm} = 11.60 L [/tex]  

Therefore, the volume of water vapor produced at STP is 11.60 L.

Answer:

(a) from the anode to the cathode through the external circuit

Explanation:

In an electrochemical cell, there are two half cells; the oxidation half cell and reduction half cell. Oxidation typically refers to loss of electrons and reduction refers to gain of electrons.

Electrons always flow from the anode to the cathode or from the oxidation half cell to the reduction half cell.

The electrical circuit in an electrochemical cell confirms the flow of electron. Usually a light bulb is attached. The correct option is;

(a) from the anode to the cathode through the external circuit

In an electrochemical cell, the direction which electrons travel is: (a) from the anode to the cathode through the external circuit.

Electrons can be defined as the subatomic particles of a chemical element that are negatively charged and have a magnitude of -1.

An electrochemical cell refers to a device that is capable of either generating electric current from the electrical energy released by a spontaneous redox reaction or using an electrical energy to cause chemical reactions.

Generally, an electrochemical cell is also referred to as a secondary cell and a good example is a rechargeable battery.

In Science, the direction of flow of current is usually from the anode (positive side) to the cathode (negative side) in an electrical circuit.

On a related, current is made up of electrons and as such the direction which electrons travel is usually from the anode to the cathode through the external electrical circuit.
