AgF (aq) + KNO3 (aq) →

Answers

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.

Explanation:

you need 16.66ml (+-0.01) of 53.4 (+-0.4)wt% of NaOH with a density of 1.52 (+-0.01)g/mL to prepare 2.00L of 0.169M of NaOH. What is the uncertainty in the molarity of NaOH. FM of NaOH=39.9971 g/mol. Neglect the uncertainty in the final volume and FM.

Answers

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.

Based on the map, which weather prediction is most valid? (1 point) A a significant drop in temperature will occur across the area. B There is no chance of precipitation in the forecast. C Warm temperatures will replace cold temperatures. D Humidity levels will rise.

Answers

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.

A student found the mass of a brick: 50 grams. The volume was 10 cubic centimeters. If the student had 5 bricks, what would be the total density?

Answers

Answer:

The answer is 5 g/cm³

Explanation:

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

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

From the question

The mass of one brick is 50 g

the volume of one brick is 10 cm³

Since the student had 5 bricks

Total mass = 5 × 50 = 250 g

total volume = 5 × 10 = 50 cm³

So the total density is

[tex]density = \frac{250}{50} = \frac{25}{5} \\ [/tex]

We have the final answer as

5 g/cm³

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.

What is density?

"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.
