Answer:
0.171 M
Explanation:
Step 1: Given data
- Mass of H₃PO₄ (solute): 3.35 g
- Volume of solution (V): 200 mL
Step 2: Calculate the moles of solute
The molar mass of H₃PO₄ is 97.99 g/mol.
3.35 g × 1 mol/97.99 g = 0.0342 mol
Step 3: Convert "V" to liters
We will use the conversion factor 1 L = 1000 mL.
200 mL × 1 L/1000 mL = 0.200 L
Step 4: Calculate the molarity of the solution
We will use the definition of molarity.
M = moles of solute / liters of solution
M = 0.0342 mol/0.200 L = 0.171 M
Answer:
the cold one is going to have a faster reaction time
Explanation:
The mass number is the summation of number of proton and neutron present in a nucleus of an atom. For the neutral atom the number of positive charge (number of proton) must be equal to the number of electrons. The number of electrons present in an atom is the atomic number of the atom. The standard way to express the mass number (a) and atomic number (m) of a atom (say X) is 
. Now for silicon number of electron or atomic number is 14. And the mass number (a) given 29. Thus the expression nucleus of silicon will be 
Ummm i actually dont know lol i swear i knew im sorry man or women ( im not trying to assume your gender
The answers are as follows:
1. TRUE, <span>The energy in a nuclear reaction comes from the transformation of mass to energy.
</span>
2. TRUE, <span>Although both fission and fusion generate energy, fusion produces much more energy than nuclear fission and produces less nuclear waste
</span>
3. TRUE, <span>In certain types of atomic bombs, a fuel, like plutonium-239, is bombarded with neutrons to create an uncontrolled nuclear reaction that splits the nuclei of the fuel.
</span>
