Answer:

A temperature inversion occurs when air near the ground is relatively cool, and there is a layer of warmer air above it. That upper layer of warm air keeps the cooler air from rising, and traps all of the pollution in the cooler, lower layer.

Answer: Gases expand to fill their containers, have a fluid nature, low density, can be compressed, diffuse and effuse - move in small hole spray perfume .

Explanation:

Gases have such an unpredictable nature like fluid, very low density, can be condensed, disperse and effuse move in tiny hole spray fragrance, and they dominate far more room than the fine solids out of which they establish. 

Because gases are harder to identify directly, gases are defined using four physical qualities or observable characteristics such as temperature, density, particles number, and volatility.

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\ [/tex]

From the question we have

[tex]density = \frac{85}{110} \\ = 0.772727272...[/tex]

We have the final answer as

The substance will float on water since it's density is less than that of water which is

1 g/cm³.

Answer:

The absolute uncertainty is approximately 1.69 × 10⁻³

Explanation:

The volume needed for NaOH needed to make the solution = 16.66 ml

The wt% of the added NaOH = 53.4 wt%

The volume of the NaOH to be prepared = 2.00 L

The concentration of the NaOH to be prepared = 0.169 M

The molar mass of NaOH = 39.997 g/mol

Therefore, 100 g of sample contains 53.4 g of NaOH

The mass of the sample = 16.66 × 1.52 = 25.3232 g

The mass of NaOH in the sample = 0.534 × 25.3232 = 13.5225888 g ≈ 13.52 g

Therefore;

The number of moles of NaOH = 13.52/39.9971 = 0.3381 moles

Therefore, we have 0.3381 moles in 2.00L solution, which gives;

The number of moles per liter = 0.3881/2 = 0.169045 moles/liter

The molarity ≈ 0.169 M

The absolute uncertainty, u(c) is given as follows;

[tex]u(c) = \sqrt{ \left (\dfrac{0.01}{16.66} \right )^2 + \left ( \dfrac{0.4}{53.4} \right )^2 + \left ( \dfrac{0.01}{1.52} \right )^2 } \times 0.169 \approx 1.69 \times 10^{-3}[/tex]

The absolute uncertainty, u(c) ≈ 1.69 × 10⁻³.

Answer:

The correct option is D) Humidity levels will rise

Explanation:

A rise in humidity means that it is most likely there is going to be a rain.

When blue semi-circle lines with triangles approach red semi-circle lines it is a situation where cold front is approaching a warm front.

The resultant effect is that the warm and cold air both come to a standstill. This will most likely trigger cloud and fog and may even lead to rain.

PLZ Brainliest

Because the rock is irregularly shaped, you used the displacement method to measure its volume. You used calculations to indirectly find the density of the objects. Thus, option 1. b and 2. a is correct.

"Density has been defined as the ratio of the mass of the object to the volume of the substance." The mass of the object must be in grams and the volume is in the liter, milliliter, or cubic centimeter.

The density of the irregular-shaped rock can be calculated by the displacement method so that the volume of the rock can be estimated. The displacement method is used to calculate the volume of irregularly shaped objects. The formula is given as,

m = ρV

Here, m is mass, ρ is density and V is volume.

Therefore, the indirect calculation can be used to estimate the density.

Answer:

AgF (aq) + KNO₃ (aq) → AgNO₃(aq) + KF(aq)

Explanation:

AgF (aq) + KNO₃ (aq) →

The products from the equation above can be obtained as follow:

1. AgF and KNO₃ will dissociate in solution as shown below:

AgF (aq) —> Ag⁺(aq) + F¯(aq)

KNO₃ (aq) → K⁺(aq) + NO₃¯(aq)

2. A double displacement reaction will occur between AgF and KNO₃ as illustrated below:

AgF (aq) + KNO₃ (aq) →

Ag⁺(aq) + F¯(aq) + K⁺(aq) + NO₃¯(aq) → Ag⁺NO₃¯(aq) + K⁺F¯(aq)

AgF (aq) + KNO₃ (aq) → AgNO₃(aq) + KF(aq)

A careful observation of the above equation shows that the equation is balanced.
