Answer:
I dont know if this is correct.. but maybe in the tool row, put graduated cylinder because you use graduated cylinders to measure water and for units put milliliters or liters?? Sorry if this isnt correct i wouldnt know what else to put !
Explanation:
A fusion reaction can be regarded as the type of reaction that occurs where two lighter elements come together in a type of reaction giving rise to a heavier/more massive element.
A fusion reaction always creates a more massive atomic nucleus (option c).
When the two lighter nuclei comes together in a reaction, a more heavier/massive nucleus is formed but its mass will still be less than the combined mass of the two reactant nuclei.
This also indicates that the left over mass may have been released as energy.

Answer:
The answer is
<h2>
</h2>
Explanation:
To find the number of atoms given the number of moles we use the formula
N = n × L
where
N is the number of entities
n is the number of moles
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question
Substitute the values into the above formula and solve
That's
<h3>
</h3>
We have the final answer as
<h3>
</h3>
Hope this helps you
Since water has a density of about 1g/mL, and we are assuming HCl and NaOH are mostly water, the total mass of the 2 solutions is 100 g.
Due to the conservation of mass, the mass of product must equal the total mass of reactant, therefore the final mass must also be 100 g.
Answer:
0.15 M KCl
Explanation:
(Step 1)
Convert the original volume from mL to L. Calculate the moles of the original solution.
75.0 mL / 1,000 = 0.0750 L
Molarity = moles / volume (L)
0.200 M = moles / 0.0750 L
0.0150 = moles
(Step 2)
Convert the final volume from mL to L. Calculate the final molarity.
100. mL / 1,000 = 0.100 L
Molarity = moles / volume (L)
Molarity = 0.0150 moles / 0.100 L
Molarity = 0.15 M
