The approach most commonly used to measure metabolic rate is to measure the rate of O2 consumption. Although there are small err

In-s [12.5K]

Explanation:

Metabollic rate is the amount of energy expended from an organism at a given point in time.

Equation of how glucose (food) is broken down via respiration:

C6H12O6(s) + 6O2(g) --> 6H2O(l) + 6CO2(g)

The amount of energy produced for the types of food is roughly proportional to the amount of oxygen use, so that the metabolic rate can be measured by measuring the rate of oxygen consumption.

Convert 34.59cm3 to cubic inches (in3) given that 1 inch = 2.54cm

JulsSmile [24]

Answer:

$2.111in^3$

Explanation:

Hello,

In this case, we are able to perform this unit conversion by cubing the relationship between inches and centimetres as shown below:

$=34.59cm^3*(\frac{1in}{2.54cm})^3 \\\\=34.59cm^3*(\frac{1in^3}{16.39cm^3} )\\\\=2.111in^3$

Best regards.

A lab analysis of 0.502 g of Scandium (Sc) reaction with Oxygen (O2) from Air resulted

VARVARA [1.3K]

The empirical formula of the metal oxide would be $Sc_2O_3$

<h3>What is empirical formula?</h3>

Mass of scandium = 0.502g

Mass of scandium + oxygen = 0.768g

Mass of oxygen = 0.768 - 0.502 = 0.266g

Mole of scandium = 0.502/44.95 = 0.011

Mole of oxygen = 0.266/16 = 0.017

Divide by the lowest:

Scandium = 0.011/0.011 = 1

Oxygen = 0.017.0.011 = 1.5

Thus, the empirical formula of the compound would be $ScO_1.5$ or $Sc_2O_3$
