Match each SI unit to the quantity it measures mass temperature time electric current
kherson [118]

<u>The S.I unit for the given term:</u>

Mass is expressed in kilogram (kg)

temperature is expressed in kelvin (K)

Time is expressed in seconds (s)

Current is expressed in ampere (A)

<u>Explanation:</u>

<u>Current: </u>

The current can be defined as the electric charge flow in the surface (means ratio of charge per unit time). It is measured in ampere (A)

             Current\ I=\frac{\text { charge }}{\text { time }}

<u>Temperature: </u>

Kelvin (K), the general temperature unit in the international standard units system. The Kelvin scale is an absolute thermodynamic temperature scale that uses absolute zero, a temperature at which all thermal movements end with a classic description of thermodynamics.

<u>Mass: </u>

Mass is both a feature of the objects weight and its resistance measurement to accelerate under the influence of pure force. The mass of the object also determines the gravitational force. The basic unit of mass is kilogram (kg)

<u>Time: </u>

Time is the measurement of how much distance the objects takes to travel from one to another (speed). It is expressed in seconds (s).

Ammonia (NH3) clouds are present around some planets. Calculate the number of grams of ammonia produced by the reaction of 5.4 g
Komok [63]

Answer:

30.4 g. NH3

Explanation:

This problem tells us that the hydrogen (H2) is the limiting reactant, as there is "an excess of nitrogen." Using stoichiometry (the relationship between the various species of the equation), we can see that for every 3 moles of H2 consumed, 2 moles of NH3 are produced.

But before we can use that relationship to find the number of grams of ammonia produced, we need to convert the given grams of hydrogen into moles:

5.4 g x [1 mol H2/(1.008x2 g.)] = 2.67857 mol H2 (not using significant figures yet; want to be as accurate as possible)

Now, we can use the relationship between H2 and NH3.

2.67857 mol H2 x (2 mol NH3/3 mol H2) = 1.7857 mol NH3

Now, we have the number of moles of ammonia produced, but the answer asks us for grams. Use the molar mass of ammonia to convert.

1.7857 mol NH3 x 17.034 g. NH3/mol NH3 = 30.4 g. NH3 (used a default # of 3 sig figs)
