Answer:

Electrons

Explanation:

Atoms can combine together and share electrons between them. Atoms that share electrons are linked to each other in a form, called a molecule that is in a lower energy state than either of the separate atoms alone.

Answer:

the gas evolved is carbon dioxide

Explanation:

for example we can have a look at sodium carbonate reaction with hydrochloric acid

when sodium carbonate reacts with hydrochloric acid, it results in sodium chloride, carbon dioxide and water.

Answer: Carbon dioxide

KE = 0

Energy is the ability to do work  

Energy because its motion is expressed as Kinetic energy (KE) which can be formulated as:  

[tex]\large{\boxed{\bold{KE=\frac{1}{2}mv^2}}}[/tex]

So for two objects that have the same speed, the greater the mass of the object, the greater the kinetic energy  

The stone in hand is in a motionless state (at rest) so that its velocity (v) = 0, so it has no kinetic energy

But this stone can have potential energy that is gained due to its height

Answer:

Gay-Lussac's law.

Explanation:

According to Gay-Lussac's pressure law, it states that the pressure of a given mass of gas is directly proportional to the absolute temperature of the gas, the assumption that the volume is kept constant.

Hence, the trucker's tires were blown up because they were under high pressure as he drove from New Jersey to California, as a result of this intense pressure the temperature of the air in the tires began to rise and it directly affected the pressure of the gas in the tires' tubes which also increased to a point that they ended up blowing out, obeying Gay-Lussac's law.

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\[/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question

N = 7.14 × 10^35 molecules of O2

We have

Answer:

It has shells of protons and neutrons.

Explanation:

The nuclear structure of an atom is similar to the non-nuclear structure because has shells of protons and neutrons.

An atom consists of a central nucleus that is usually surrounded by one or more electrons.

The total number of neutrons plus protons in the same both before and after the nuclear process, although the total number of protons and the total number of neutrons may be different before and after.

Hence, the nuclear structure of an atom is similar to the non-nuclear structure because has shells of protons and neutrons.

Answer:

I've already answered this one for you. Anyway, please let me know if you have any more questions or need help!

The speed of the yacht : 100 km/h

Linear motion consists of 2: constant velocity motion with constant velocity and uniformly accelerated motion with constant acceleration  

the speed of vo = v = constant

acceleration = a = 0  

Δx = vt or x = xo + vt  

An equation of constant velocity motion  

[tex]\large {\boxed {\bold {x = v \times \: t}}}[/tex]

x = distance = m  

v = speed = m / s  

t = time = seconds  

A yacht sailed at a steady speed for 0.5 hours, and traveled 50 kilometers

Explanation:

Answer:If you change the number of neutrons in an atom, you get an isotope of the same element. The addition of a neutron can make an atom radioactive. When you change the number of protons in an atom, you will change the atom from one element to a different element.

Answer:

The correct option is;

Determine the density of the object and compare the known density of pure Silver

Explanation:

The density of the object is found by finding the weight of the object, and then finding the volume (of water) the object displaces when it is immersed (in water)

The  density is then fond by dividing the weighed mass by the volume the object displaces when immersed

Compare the result of the measured density with that of pure silver. If the two have density, as well as other similar physical characteristics, then the object is likely to be pure silver.

If the normal melting point of a substance is below room temperature, the substance is a liquid at room temperature.

If both the normal melting point and the normal boiling point are above room temperature, the substance is a solid.

Answer:

A description of the experiment the chemicals were used for.

Explanation:

A chemical waste label is required to provide information about any hazardous waste present in the container. Some details are mandatory to mention of the chemical waste label to prevent any accident while doing the experiment, that includes:

A chemical waste label does not mention or describe the experiment for which the chemicals were used for, scientists, teacher or students should have knowledge of the chemical composition by reading their names and evaluate themselves on which chemical should be used for which experiment.

Hence, the correct answer is  "A description of the experiment the chemicals were used for."

Answer:

Insoluble substances remain the same when in water.

Explanation:

When a substance is regarded as insoluble, it means that the substance remains the same in water.

Soluble substances usually form one continuous phase with water when they are added to water (eg when salt is added to water).

However, when camphor is added to water, it does not form a single phase with water. It remains the same in the water and maintains a separate phase from the water. Hence camphor is an insoluble substance.

Answer:

The solution will fit into the container.

Explanation:

The following data were obtained from the question'

Volume of solution = 170 L

Length of container (L) = 2.5 ft

Height of container (H) = 60 cm

Width of container (W) = 0.8 m

Volume of container (V) =?

Next, we shall express the length, height and breadth I the same unit of measurement. In this case, we shall all in centimetres (cm).

For the length:

1 ft = 30.48 cm

Therefore,

2.5 ft = 2.5 ft × 30.48 cm / 1 ft

2.5 ft = 76.2 cm

Thus the length is 76.2 cm

For the width:

1 m = 100 cm

Therefore,

0.8 m = 0.8 m × 100 cm / 1 m

0.8 m = 80 cm

Thus, the width of the container is 80 cm.

Next, we shall determine the volume of the container as follow:

ength of container (L) = 76. 2 cm

Height of container (H) = 60 cm

Width of container (W) = 80 cm

Volume of container (V) =?

Volume = length × width × height

Volume = 76.2 × 80 × 60

Volume = 365760 cm³

Finally, we shall convert 365760 cm³ to litre (L). This can be obtained as follow:

1000 cm³ = 1 L

Therefore,

365760 cm³ = 365760 cm³ × 1 L/ 1000 cm³

365760 cm³ = 365.76 L

Therefore, the volume of the container is 365.76 L

Since the volume of the container (i.e 365.76 L) is bigger than the volume of the solution (i.e 170 L), therefore, the solution will fit into the container.
