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.

Classify each of the following properties of a cake as qualitative or quantitative. Give reasons for your answers
VashaNatasha [74]

Answer:

The answer to your question is below

Explanation:

A qualitative property of matter is a property characteristic of a substance like color and flavor.

A quantitative property of matter is a property when we get a number.

A) it's a circular shape  is a qualitative property because the shape is a qualitative property and shape is not represented by a number.

B) its mass is 1.5 kg  is a quantitative property because we know a number of this mass.

C) it tastes like chocolate  is a qualitative property because the flavor is characteristic of a substance and flavor is not measured in numbers.

D) it is 30 cm in diameter  it is a quantitative property, we know the exact dimension of it.

E) its icing is melting is a qualitative property, melting is a property of ice, it just happens.

The ratio of oxygen to carbon by mass in carbon monoxide is 1.33:1.00. part a find the formula of an oxide of carbon in which th
zheka24 [161]

To calculate the molecular formula, convert the mass ratio into molar ratio as follows:

mass ratio of O:C=2:1

molar mass of carbon is 12 g/mol and that of oxygen is 16 g/mol thus, number of moles can be calculated as follows:

n=\frac{m}{M}

calculating ratio,

O:C=\frac{2 g}{16 g/mol}:\frac{1 g}{12 g/mol}=\frac{1}{8}:\frac{1}{12}=12:8=3:2

thus, molecular formula will be C_{2}O_{3}
