A typical atom has six protons and six neurons, and it has an atomic weight of 12 Amu. A carbon also has six electrons, but they are so small that they don’t contribute to carbons weight. An element is defined by the number of protons in its nucleus
<h2>Hello!</h2>
The answer is: False.
Why?
It's known that most common galaxies are spiral - shaped, but according to some studies, the irregular - shaped galaxies can not be even considered "spiral shaped".
Irregular - shaped are galaxies defined by their lack of structures, and they were formed by an external gravitonal force acting, in fact, it's believed that they were spiral or elliptical galaxies before.
An example of irregular - shaped galaxies is Small Magenallic Cloud.
Have a nice day!
Answer:
0.0102 L or 10.2 mL
Explanation:
From the question given above, the following data were obtained:
Molarity = 0.250 M
Mole = 0.00255 mole
Volume =?
Molarity is simply defined as the mole of solute per unit litre of the solution. Mathematically, it is expressed as:
Molarity = mole / Volume
With the above formula, we can obtain the volume as follow:
Molarity = 0.250 M
Mole = 0.00255 mole
Volume =?
Molarity = mole / Volume
0.250 = 0.00255 / volume
Cross multiply
0.250 × volume = 0.00255
Divide both side by 0.250
Volume = 0.00255 / 0.250
Volume = 0.0102 L
Covert 0.0102 L to mL.
1 L = 1000 mL
Therefore,
0.0102 L = 0.0102 L × 1000 / 1 L
0.0102 L = 10.2 mL
Thus, the volume is 0.0102 L or 10.2 mL
Combustion is burning and that usually produces carbon in the reaction adding it to the atmosphere
Hey there!
There are 1000 mL in a liter.
1.4 L + 0.045 L = 1.445 L
In total there is 1.445 L of the solution.
To find the percent of isopropyl alcohol, divide the amount of isopropyl alcohol by the total amount.
0.045 ÷ 1.445 = 0.0311
Convert to a percent.
3.11%
Hope this helps!
