In Africa, the oxpecker is a bird that eats bugs and other parasites from the skin of a rhino. This helps protect the rhino’s skin and keeps the bird fed. Which of the following describes the type of relationship that exists between the oxpecker and the rhino?

Based on the law of conservation of mass, there is no loss in mass in the reaction, however carbon dioxide gas is evolved.

The law of conservation of mass states that for a chemical change occurring, the sum of masses before and after the reaction is constant.

Based on the law of conservation of mass, the reaction between 10.04g of calcium carbonate and 20cm3 of 1m hydrochloric acid will have the same mass before and after the reaction. Any change in mass will be due to evolution of carbon dioxide gas.

Therefore, there is no loss in mass in the reaction, however carbon dioxide gas is evolved.

We know the formula

C is concentration and V is volume

The new volume will be by using the relation between molarity and volume formula.

Molarity, also termed as molar concentration in a solution, is a method of determining how much material is present in a chemical solution.

Calculation of volume with the aid of molarity formula is shown below:

Volume is calculated by using the molarity formula.

[tex]M_{1} V_{1} = M_{2} V_{2}[/tex]

Where, M is molarity and V is volume.

It is given that, [tex]M_{1}[/tex] = 0.750 M , [tex]M_{2}[/tex] = 0.500 M, [tex]V_{1}[/tex] = 275 ml .

Now, put the value of given data in molarity formula.

[tex]M_{1} V_{1} = M_{2} V_{2}\\V_{2} = M_{1} V_{1} / M_{2}\\V_{2} = (0.750 M) (275 ml) / 0.500 M\\V_{2} = 183.34 ml[/tex]

Therefore, the volume will be 183.34 ml.

Answer:

Stage 3 or long-term immersion hypothermia happens after 30 minutes or more. Cold water pulls heat from the body, and the body’s core temperature drops. This eventually leads to loss of consciousness and death.

Answer:

Reverse Osmosis

Explanation:

Reverse osmosis systems are able to remove more contaminants than carbon, making them a popular choice for many consumers.

At constant temperature, if the volume of the gas is doubled, the pressure also doubles. The new pressure of the gas is 50°C.

Charles's law states that "the volume occupied by a definite quantity of gas is directly proportional to its absolute temperature.

It is expressed as;

V₁/T₁ = V₂/T₂

Given that;

If final volume is double of initial volume.

V₁/T₁ = V₂/T₂

V₁T₂ = V₂T₁

T₂ = V₂T₁ / V₁

T₂ = ( 1000cm³ × 25°C ) / 500cm³

T₂ = 25000m³°C / 500cm³

T₂ = 50°C

At constant temperature, if the volume of the gas is doubled, the pressure also doubles. The new pressure of the gas is 50°C.

The presence of lead in Flint's water is what caused the death of 12 people.

Option A.

The Flint water crisis started in 2014 when the city of Flint, Michigan, switched its water source from Lake Huron to the Flint River as a cost-cutting measure.

The water from the Flint River was more corrosive and caused lead to leach from the pipes, contaminating the drinking water. This led to high levels of lead in the drinking water, which is a potent neurotoxin that can cause a variety of health problems, particularly in children.

The contamination also led to an outbreak of Legionnaires' disease, a severe form of pneumonia, which was linked to at least 12 deaths in the area.

It totally depends on the laser power (mW). The divergence of the light is depending on it.

A device that uses stimulated emission of photons from excited atoms or molecules to produce a strong beam of coherent monochromatic light is a laser.

When electrons in optical materials like glass, crystal, or gas absorb energy from an electrical current or light, a laser is formed.

When a 5mW 650 nm laser glows on a white surface in complete darkness, we can see it from 500 to 1 km distant.

Because of the divergence, the projected dot 1 km distant will be a huge dot with a diameter of 20–30 m30 m and will be extremely dim.

A combustion reaction is a reaction that reacts with oxygen to produce the product. 3.5 moles of methane release - 3115 kJ/mol of heat.  

A combustion reaction is a chemical reaction that involves the burning of the reactant in the presence of the oxygen molecule to release heat.

The balanced reaction of methane combustion is given as:

CH₄(g) + 2O₂ (g) → CO₂(g) + 2H₂O (l), ΔH = -890 kJ/mol

From the reaction, it can be said that 1 mole of methane combusts to produce -890kJ/mol enthalpy.

So, 3.5 moles will produce, 3.5 × -890kJ/mol = - 3115 kJ/mol.

Therefore, 3.5 moles of methane produce - 3115 kJ/mol heat.

The phase of water at 0.5 atm and 100°C is gaseous phase.

Water exists in three different phases such as liquid, gas, and solid.

The phase of the given water can be determined using phase diagram at standard temperature and pressure as shown in the image uploaded.

At 0.5 atm and 100 °C, the water is still in vapour or gaseous phase.

Thus, the phase of water at 0.5 atm and 100°C is gaseous phase.

Answer:

The law of constant proportion states that the percentage of each compound will stay constant regardless of the source size.

In other words, since 11.19% + 88.81% = 100%, in a 100 gram sample, these percentages will stay the same. In this case, 100% is "equal" to 100 grams.

Here down below is the equation

Explanation:

Iron (III) chloride can be produced by the reaction shown in this equation:

2Fe +3C2 (arrow) 2FeCl3

Calculate the maximum mass of Iron (III) chloride that can be produced from 11.20 grams of iron?

Relative atomic masses: Cl= 35.5 , Fe =56

The maximum mass of iron(|||) chloride(FeCl₃) that can be produced from 11.20g of iron is 0.069 grams.

Mass can be defined as inertia is a quantitative measure of a fundamental feature of all stuff.

It can also be defined as weight is defined as the force exerted by an item while mass is defined as the amount of matter in an object.

The SI unit of mass is kilogram or gram.

Mass can be expressed as

Mass =  Given mass of substance / Formula mass

Mass of substance = 11.20 g

Formula mass of FeCl₃ = 162.2

So, mass = 11.20 g / 162.2 g

               = 0.069 grams

Thus, the maximum mass of iron(|||) chloride(FeCl₃) that can be produced from 11.20g of iron is 0.069 grams.
