Answer:

1. Using Litmus papers. Litmus paper will turn blue if solution is acidic or it will turn blue if it is basic. ... If pH is below 7 or reddish then the given solution is acidic and if pH is higher than 7 or bluish then the solution is basic.

Answer:

Explanation:

One: You could mix a small sample of it with a reactive metal. Underline small. You should see gas bubbles being given up. Usually the bubbles are hydrogen.

Example : K + HCl ===> KCl + H2

Two: You could use an indicator to watch it turn color as it goes from acidic to neutral. Litmus will go from red to blue under these conditions.

Three: Those are the two safest ways. If you knew the acid was dilute, you could put a small (underline small again) amount on your tongue. If it tastes like orange juice, it is likely an acid. This is a test every textbook mentions. You should never do it under any circumstances.

This stadium can hold 100,000, or 1 x 105, people. The number of atoms in a grain of iron is about 1 x 1018. Would you need 1 x

<h3>Answer:</h3>

1 x 10^13 stadiums

<h3>Explanation:</h3>

We are given that;

1 stadium holds = 1 × 10^5 people

Number of iron atoms is 1 × 10^18 atoms

Assuming the stadium would carry an equivalent number of atoms as people.

Then, 1 stadium will carry 1 × 10^5 atoms

Therefore,

To calculate the number of stadiums that can hold 1 × 10^18 atoms we divide the total number of atoms by the number of atoms per stadium.

Number of stadiums = Total number of atoms ÷ Number of atoms per stadium

= 1 × 10^18 atoms ÷ 1 × 10^5 atoms/stadium

= 1 × 10^13 Stadiums

Thus, 1 × 10^18 atoms would occupy 1 × 10^13 stadiums

Perform the following conversion: 6.1 × 103 K (the surface temperature of the Sun) to °F and °C. Pay attention to the number of

Keith_Richards [23]

Answer:

$\°C=5.8x10^3\°C$

$\°F=1.1x10^4\°F$

Explanation:

Hello,

In this case, for the calculation of the temperature in degree Celsius we subtract 273.15 to the given temperature in kelvins:

$\°C=6100-273.15\\\\\°C=5.8x10^3\°C$

Next, by applying the following equation we compute it in degree Fahrenheit:

$\°F=(5.8x10^{3}*9/5) + 32\\\\\°F=1.1x10^4\°F$

Clearly, since the initial unit has two significant figures the computed units also show two significant figures.

Regards.

An ice cube measuring 5.80 cm by 5.80 cm by 5.80 cm has a density of 0.917 g/mL What is the mass?

OLga [1]

Answer: 178.9 g

Explanation:

Density = $\frac{mass}{volume in mL}$

find volume of the cube: (5.80 cm) (5.80 cm) (5.80cm) = 195.112 cm³

1.0 cm³ = 1.0 mL

so 195.112 cm³ = 195.112 mL

plug value into density equation:

0.917 g/mL = (mass) / (195.112 mL)

and solve for mass!
