Explain why.

Answer:

gamma

Explanation:

The type of radiation that is being emitted from the rock is beta radiation.

Alpha particles are positively charged particles that are made up of two protons and two neutrons. They are the least penetrating type of radiation and can be stopped by a sheet of paper.

Beta particles are negatively charged particles that are made up of electrons. They are more penetrating than alpha particles and can be stopped by aluminum foil.

Gamma rays are high-energy photons that are not charged. They are the most penetrating type of radiation and can only be stopped by thick layers of lead or concrete.

In the case of the rock, the radiation is being stopped by the aluminum foil, which means that it must be beta radiation. Beta particles are more penetrating than alpha particles, but they are still not as penetrating as gamma rays. This means that the rock is probably not emitting gamma rays, and the only other possibility is beta radiation.

Answer:

The amount of water converted from liquid to gas with 6,768 joules is approximately 3.035 g

Explanation:

The amount of heat required to convert a given amount of liquid to gas at its boiling point is known as the latent heat of evaporation of the liquid

The latent heat of evaporation of water, Δ\(H_v\) ≈ 2,230 J/g

The relationship between the heat supplied, 'Q', and the amount of water in grams, 'm', evaporated is given as follows

Q = m × Δ\(H_v\)

Therefore, the amount of water, 'm', converted from liquid to gas at the boiling point temperature (100°C), when Q = 6,768 Joules, is given as follows;

6,768 J = m × 2,230 J/g

∴ m = 6,768 J /(2,230 J/g) ≈ 3.035 g

The amount of water converted from liquid to gas with 6,768 joules = m ≈ 3.035 g.

Answer:

Ionic bond

Explanation:

Covalent bonds can only form between non-metals and copper is a metal so it would be an ionic bond.

CuO (copper(II) oxide) is a compound with a covalent bond. The electronegativity difference is less than 1.7, which would make it a covalent bond.

In a covalent bond, atoms share electrons to form a stable molecule. The electronegativity difference between copper (Cu) and oxygen (O) is less than 1.7, indicating a nonpolar covalent bond. This means that the electrons in the bond are shared relatively equally between the copper and oxygen atoms, resulting in a molecule with a low degree of polarity.

Copper is a transition metal with an electronegativity of around 1.9, and oxygen has an electronegativity of approximately 3.44. The electronegativity difference (3.44 - 1.9 = 1.54) is less than 1.7, confirming that the bond between copper and oxygen is covalent rather than ionic.

In ionic bonds, the electronegativity difference is typically larger than 1.7, leading to a transfer of electrons from one atom to another, resulting in the formation of ions. Since the electronegativity difference in CuO is less than 1.7, it is considered a covalent bond.

Other forms of  electromagnetic radiation that could cause ionization are  X-rays and gamma rays

Ionizing radiation is a form of energy that acts generally by removing electrons from atoms and molecules of materials that include air, water, and living tissue etc. Ionizing radiation can travel unseen and can pass through these materials.

Human activities, such as making medical x- rays, generating electricity from nuclear power plants , testing the nuclear weapons, and producing a wide variety of common products such as smoke detectors which usually contains radioactive materials, can cause additional exposure to ionizing radiation as well.

X-rays and gamma rays have enough energy so that during interaction with atoms, they are capable to remove electrons and cause the atom to become charged or ionized. hence we can call them to be ionizing radiation.

Answer:

0.972

Explanation:

The balanced chemical equation for the reaction is:

3 NaOH + H3PO4 → Na3PO4 + 3 H2O

From the equation, we can see that for every 1 mole of H3PO4 reacted, 3 moles of water are produced. Therefore, we need to first calculate how many moles of H3PO4 are present in 4.30 g of NaOH:

molar mass of NaOH = 23.0 g/mol + 16.0 g/mol + 1.0 g/mol = 40.0 g/mol

moles of NaOH = 4.30 g / 40.0 g/mol = 0.108 mol

According to the balanced equation, 3 moles of water are produced for every 1 mole of H3PO4. Therefore, we can calculate how many moles of water are formed as follows:

moles of H3PO4 = 3/1 * 0.108 mol = 0.324 mol

moles of water = 3/1 * 0.324 mol = 0.972 mol

Therefore, 0.972 moles of water are formed when reacting 4.30 g of sodium hydroxide with phosphoric acid.

AlBr_{3} is an acid according to the Lewis theory of acids and bases since it accepts a pair of electrons .

According to Lewis theory, a substance is considered an acid if it can accept a pair of electrons (an electron pair acceptor) and a substance is considered a base if it can donate a pair of electrons (an electron pair donor). With this in mind, we can determine whether AlBr3 is an acid or a base.Lewis theory explains the chemical bonding in a compound in terms of the transfer of electrons. In Lewis theory, a substance can either donate or accept electrons, and this determines whether it is an acid or a base. If a substance can accept electrons, it is an acid. If a substance can donate electrons, it is a base.AlBr3 is a compound that consists of aluminum and bromine. Aluminum has three valence electrons while bromine has seven valence electrons. The aluminum atom donates its three valence electrons to the bromine atoms, which accept the electrons to form AlBr_{3}. Since aluminum donates electrons, it is considered a base, while bromine accepts electrons and is an acid. Therefore, AlBr_{3} is considered an acid. The chemical equation of the formation of AlBr3 is shown below: Al + 3Br → AlBr_{3} In summary, AlBr3 is an acid according to the Lewis theory of acids and bases since it accepts a pair of electrons (an electron pair acceptor).

"Hypotonic solution," refers to a solution with the highest water concentration due to its lower solute concentration compared to the other options, leading to water influx into cells.

A hypotonic solution would be most likely to have the highest water concentration. In a hypotonic solution, the solute concentration is lower than that inside the cell or compared to another solution. As a result, water tends to move into the cell or the solution to equalize the concentration.

When a cell is placed in a hypotonic solution, water molecules will move into the cell through the process of osmosis. This influx of water increases the water concentration inside the cell, leading to cell swelling or even bursting in extreme cases.

Compared to hypertonic and isotonic solutions, a hypotonic solution has a lower solute concentration, allowing for a higher concentration of water molecules. This results in a higher water concentration in the solution. It's important to note that the concept of tonicity is related to the relative solute concentrations between two solutions and their effect on cell osmosis. In this case, a hypotonic solution is characterized by a higher water concentration compared to the other options.
