T = final temperature  of the block

T₀ = initial temperature of the block = 23.4 °C

Q = energy lost  from the wooden block = - 759 J

c = specific heat capacity of wood = 1.716 J/(g  °C)

m = mass of the wooden block = 27.2 g

Heat lost from the block is given as

Q = m c (T - T₀)

inserting the values

- 759 = (27.2) (1.716) (T - 23.4)

T = 7.1 °C

The final temperature of a 27.2-gram wooden block is 7.1 °C. The correct option is A.

Temperature is the measurement of the hotness or coldness of the body. It is denoted by Kelvin.

By specific heat equation

[tex]Q = mc (T - T_\circ)[/tex]

where T = final temperature

T₀ is the initial temperature =23.4 °C

Q is lost energy from the block = - 759 J

c is specific heat = 1.716 joules/gram

m is the mass of the block = 27.2 g

Putting the values in the equation

[tex]\rm - 759 = (27.2) (1.716) (T - 23.4) = 7.1_\circ C[/tex]

Protons in an atom of Zn:  30

Electrons in a Zn atom: 30

Neutron in an atom of Zn: 35

Answer: Number of protons and electrons in Zinc are 30 and number of neutrons in zinc are 35.

Explanation:

Zinc is the 30th element of the periodic table having mass number of 65.

Atomic number = Number of protons = Number of electrons

For Zinc:

Z = 30

So, Number of protons = Number of electrons = 30

Mass number = Number of neutrons + Number of protons

A = 65

So, Number of neutrons = 65 - 30 = 35

Hence,  number of protons and electrons in Zinc are 30 and number of neutrons in zinc are 35.

The correct density of helium should be in [tex]\( \text{kg/m}^3 \)[/tex]. The calculated mass of helium in the blimp is approximately 1,121.908 kg.

The question asks us to find the mass of the helium in a blimp. To do this, we need to use the density of helium and the volume of the blimp.

However, the density provided in the question is not correctly stated because density should be mass per volume, usually given in grams per liter [tex](\( \text{g/L} \))[/tex] or kilograms per cubic meter [tex](\( \text{kg/m}^3 \))[/tex].

Assuming that the correct density of helium is 0.1786 [tex]\( \text{kg/m}^3 \)[/tex] (as would be common for a question of this nature), and the volume of the helium is given as [tex]\( 6.28 \times 10^9 \)[/tex] milliliters, we first need to convert the volume from milliliters to cubic meters to match the units of the density [tex](since \( 1 \) mL = \( 1 \times 10^{-6} \) \( \text{m}^3 \))[/tex].

First, convert the volume:

[tex]\( \text{Volume in cubic meters (m}^3\text{)} = 6.28 \times 10^9 \) mL \( \times 1 \times 10^{-6} \) \( \text{m}^3/\text{mL} \)\\ \( = 6.28 \times 10^3 \) \( \text{m}^3 \)[/tex]

Then calculate the mass: [tex]\( \text{Mass} = \text{Density} \times \text{Volume} = 0.1786 \) \( \text{kg/m}^3 \) \( \times 6.28 \times 10^3 \) \( \text{m}^3 \)[/tex]

[tex]\( \text{Mass of helium} = 1,121.908 \) kg[/tex]

The mass of helium in the blimp is approximately 1,121.908 kilograms.

The density of an object, a fundamental principle in physics, is calculated by dividing its mass by its volume. In the case of the iron piece that has a mass of 63.5g and a volume of 11.6 cm3, its density is calculated to be 5.47 g/cm3.

The density of an object is calculated by dividing its mass by its volume. This concept is a fundamental principle in physics. In this case, the piece of iron has a mass of 63.5g and a volume of 11.6 cm3. Thus, the density can be calculated using the formula density = mass/volume.

So, density = 63.5g / 11.6 cm3 = 5.47 g/cm3. Therefore, the density of the given piece of iron is 5.47 g/cm3.

A neutral atom has equal number of protons and electrons. A +ion or cation is an atom that has lost electrons, thus having a net positive charge. A -ion or anion is an atom that has gained electrons, resulting in a net negative charge.

An atom is considered neutral when it has an equal number of protons and electrons. The protons carry a positive charge and the electrons carry an equal magnitude of negative charge, so when the numbers are equal, their charges cancel each other out, leading to a balanced, or 'neutral', overall charge.

A +ion, or cation, is an atom (or a molecule) that has lost one or more electrons. Since electrons have negative charge, the loss of electrons leads to an excess of positive charge, making the atom or molecule a positive ion.

Conversely, a -ion, or anion, is an atom (or a molecule) that has gained one or more electrons. Since electrons carry negative charge, the gaining of electrons leads to an excess of negative charge, making the atom or molecule a negative ion.

You can boil or evaporate the water and the salt will be left behind as a solid. If you want to collect the water, you can use distillation. This works because salt has a much higher boiling point than water. One way to separate salt and water at home is to boil the salt water in a pot with a lid. So, I would say maybe oil.

For the first one, you have to find one that has both a metal and a nonmetal in it, plus potassium. Bonds between nonmetals are called covalent because they share electrons and a bond between a metal and a nonmetal is an ionic bond because they exchange electrons.

Potassium chloride is KCl. Only an ionic bond.

Potassium hydride is KH. Only an ionic bond.

Potassium nitrate is KNO3. There we go, that has a covalent bond between the nitrogen and oxygen, and an ionic bond between potassium and the nitrogen and oxygen.

For the second one, potassium chloride is the answer because the other three also have covalent bonds. Chloride is the only one that isn't a compound.

An atom is the smallest unit of matter that retains all of the chemical properties of an element. Atoms are made up of smaller particles called subatomic particles, including protons, neutrons, and electrons. Different types of atoms correspond to the different elements on the periodic table.

Among the options you provided, option 'a' most accurately describes an atom: An atom is the smallest particle of an element. Indeed, an atom is the smallest unit of matter that retains all of the chemical properties of its corresponding element. For example, one gold atom retains all of the properties of the element gold.

Atoms themselves are composed of even smaller particles called subatomic particles, including protons, neutrons, and electrons. These subatomic particles contribute to the atom's mass and unique properties. The number of protons and neutrons gives mass to the atom while the number and arrangement of electrons determine the element's properties.

It's also important to note that while all matter is made up of atoms, not all substances are made of the same atoms as suggested by option 'd'. Each type of atom corresponds to a specific element on the periodic table, and these different types of atoms can combine in various ways to form all the diverse substances we see in our universe.

Do you relizes how many activities lead to global warming? When gas is burned in a car, it produces carbon dioxide (a green house gas). The carbon dioxide then floats up towards the atmosphere and becomes part of the atmosphere. This then causes the heat from the sun to get trapped, bouncing from the atmosphere to the earth. The sun will never stop producing heat which will only lead to the world getting hotter as each decade goes by.  

Hope this helps you!

Many every day activities lead to global warming because they produce pollution. When gas is burned in a car, it produces carbon dioxide, a Greenhouse gas. It floats up towards the atmosphere, and makes holes in the atmosphere which lets in those harmful UV radiation and sometimes also adds more atmosphere which could turn earth into the next venous. This causes the heat from the sun to get trapped, bouncing from the earth to the atmosphere. The sun doesn't stop producing heat, so the world gets hotter, causing many changes in temperature each decade that goes by.

The correct answer is option (C). Typically protons cannot be removed from the atom.

Protons, along with neutrons, are the subatomic particles that make up the nucleus of an atom. They are held together by the strong nuclear force, which is one of the four fundamental forces of nature. This force is so strong that it overcomes the electromagnetic repulsion between the positively charged protons. As a result, protons cannot be easily removed from the atom through typical chemical reactions or processes.

Electrons, on the other hand, are much less massive and are bound to the atom by the electromagnetic force, which is weaker than the strong nuclear force. Electrons can be removed or added to an atom during chemical reactions, a process that results in the formation of ions.

Neutrons are neutral particles found in the nucleus along with protons. While they are not electrically charged like protons, they still contribute to the mass of an atom and play a role in nuclear reactions. Similar to protons, neutrons are also held in the nucleus by the strong nuclear force and cannot be removed through chemical means.

Tachyons are hypothetical particles that are said to move faster than the speed of light. They are not part of the known structure of atoms and are not considered in the context of typical atomic or chemical processes.
