Answer:
1g = 6.022 x 1023 AMU
Explanation:
An atomic mass unit or AMU is a physical constant which is equal to one-twelfth of the mass of an unbound carbon-12 atom.
One unified atomic mass unit is equal to 1.66 yoctograms = 1.66053904020 x 10-24 g.
1 AMU is equivalent to 1.66 x 10-24 grams and 1 gram is equivalent to 6.022 x 1023 AMU.
Thus,1g = 6.022 x 1023 AMU.
a) Mass of gasiline = 18.9 kg; b) distance travelled = 204 mi
a) <em>Mass of gasoline
</em>
<em>Step 1</em>. Convert <em>$CDN to $US</em>
$US = $30.00 CDN × (0.942$US/$1 CDN) = $28.26 US
<em>Step 2</em>. Calculate the <em>volume of gasoline
</em>
V = $28.26 US × (1 gal gasoline/$3.82 US) = 7.399 gal
<em>Step 3</em>. Convert <em>gallons to litres
</em>
V =7.399 gal × (3.785 L/1 gal) = 28.00 L
<em>Step 4</em>. Calculate the <em>mass of the gasoline
</em>
Mass = 28 000 mL × (0.674 g/1 mL) = 18 900 g = 18.9 kg
<em>
b) Distance travelled
</em>
<em>Step 1</em>. Calculate the <em>kilometres</em>
Kilometres = 28.00 L × (100 km/8.53 L) = 328.3 km
<em>Step 2</em>. Convert <em>kilometres to miles</em>
Miles = 328.3 km × (1 mi/1.609 km) = <em>204 mi</em>
Answer:
hello your question is incomplete below is the missing part of the question
Keisha makes a table to compare plasmas and solids.
Plasma
Solid
Kinetic energy
X
Density
Y
Which labels belong in the cells marked X and Y? X: High Y: High X: High Y: Low X: Low Y: High X: Low Y: Low
answer : X: High Y:High
Explanation:
The labels that belong in the cells are ; X: High Y:High this because when comparing Plasma and Solids the variables; X and Y have positive correlation hence when X is High, Y will be High as well
Answer:
A) They get oxidized into carbon monoxide and carbon dioxide by the oxygen molecules generated on the electrode.
Explanation:
In the electrolysis of Aluminium, the oxygen reacts with the carbon anodes forming carbon dioxide. That is, the anodes are oxidized. To ensure that the reaction completes, the anode must gradually be replaced as the reaction proceeds. The correct option is hence;
A) They get oxidized into carbon monoxide and carbon dioxide by the oxygen molecules generated on the electrode.
Answer:
Compound are substances which can be formed by chemically combining two or more elements. Mixtures are substances that are formed by physically mixing two or more substances. Compounds can be of three types, which are: covalent compounds, metallic compounds and ionic compounds.
