The reaction of potassium iodide with silver nitrate results in the formation of silver iodide as a precipitate.

<h3>What is a precipitate?</h3>

A precipitate is given as the solid deposition in the solution. It is formed as the product in the chemical reaction with the insolubility in the solution.

The reaction of KI with silver nitrate results in the formation of soluble potassium nitrate and insoluble silver iodide, which forms as the precipitate.

Thus, the reaction of potassium iodide with silver nitrate results in the formation of silver iodide as a precipitate.

At what temperature (°C) will a 10.00 g sample of neon gas exert a pressure of 96.7 kPa in a
Eva8 [605]

Answer : The temperature of neon gas will be, 221.0 K

Explanation :

To calculate the temperature of neon gas we are using ideal gas equation.

PV=nRT\\\\PV=\frac{w}{M}RT

where,

P = pressure of neon gas = 96.7 kPa = 0.955 atm

Conversion used : (1 atm = 101.3 kPa)

V = volume of neon gas = 9.50 L

T = temperature of neon gas = ?

R = gas constant = 0.0821 L.atm/mole.K

w = mass of neon gas = 10.00 g

M = molar mass of neon gas = 20 g/mole

Now put all the given values in the ideal gas equation, we get:

(0.955atm)\times (9.50L)=\frac{10.00g}{20g/mole}\times (0.0821L.atm/mole.K)\times T

T=221.0K

Therefore, the temperature of neon gas will be, 221.0 K

A company produces and tests a new mineral supplement designed to prevent the common
irga5000 [103]

A change which would remove the source of this error is to: Test a fourth group, in which participants do not receive the mineral supplements.

<h3>What is a scientific method?</h3>

A scientific method can be defined as the various techniques that are adopted to observe, investigate, examine and study a particular thing while giving explanations on the basis of the evidence, theory, proof, hypothesis, or factual information they derived from the research work.

In this scenario, a claim was made by the company its mineral supplements can effectively prevent common cold. However, this claim was disputed by a scientist because there exist an error in the group setup.

<h3>How to remove an error in science</h3>

For this investigation, an effective and efficient way to remove this source of error would be by testing a fourth group, in which the mineral supplements is not administered to any of the participants.

How many kilowatt hours does it take to lift an apple that weighs 100g 1 meter.(use 9.8 kg
kati45 [8]

Answer:

The answer to your question is   Power = 0.98 W  or 9.8 x 10⁻⁴ kW

Explanation:

Data

Power = ?

mass = 100 g = 0.1 kg

distance = 1 m

gravity = 9.8 m/s²

Formula

Power = Work / time

Process

1.- Calculate the Work

      Work = Force x distance

      Force = mass x gravity

      Work = mass x gravity x distance

      Work = (0.1 kg)(9,8)(1)      

      Work = 0.98 J

2.- Calculate the power

       Power = 0.98 J / 1 h

       Power = 0.98 W  or 9.8 x 10⁻⁴ kW
