If a chemical reaction such as photosynthesis begins with 6 atoms of carbon C , how many atoms of carbon C should be in the prod
pochemuha
B. 6 atoms of carbon C
I would think this is the answer, because one can't just delete or add atoms; otherwise, the equation would be unbalanced. This also abides with the Law of Conservation of Mass.

Plus, I also came to that conclusion because if we look at the net equation of photosynthesis:
6C O_{2} + 6H_{2}O ––> C_{6}H_{12}O_{6} + 6O_{2}
The number of Carbon atoms is 6 on both the reagent's side and the product's side.

How many moles of sodium, in 2.0 moles of sodium sulfate? Show all the work.
kiruha [24]
4 moles of sodium because you originally have 2.0 moles of Na2SO4 and you set that up at the beginning of the (what we called) train tracks. Then diagonally from that, on the bottom you put 1 mol of Na2SO4 to cancel the units. Then above that you have 2 moles of sodium because that is how many there are in the equation that they gave (the Na2 part). Then its just like a fraction, you multiply the top by the top and the bottom by the bottom, which would give you 4moles/1 or just 4 moles Na. I hope that helps

Can someone assist me with this chemistry question please?​
telo118 [61]

Answer:

490 J.

Explanation:

The following data were obtained from the question:

Mass (m) = 5 Kg

Height (h) = 10 m

Acceleration due to gravity (g) = 9.8 m/s²

Potential energy (P.E) =..?

Potential energy is the energy stored in a body by virtue of its location. Mathematically, it can be expressed as:

P.E = mgh

Where:

m is the mass of the object measured in kilograms (Kg).

g is the acceleration due to gravity and the value is 9.8 m/s².

h is the height to which the object is located measured in metre (m)

P.E is the potential energy measured in joule (J).

With the above formula, we can obtain the potential energy possed by the object as follow:

P.E = mgh

P.E = 5 x 9.8 x 10

P.E = 490 J

The,the potential energy possed by the object is 490 J

What is the mass, in grams, of a sample of 6.98 × 1024 atoms of magnesium (Mg)? Show your work or explain the steps that you use
CaHeK987 [17]

Hello!

* First Step: to know Avogrado's Law

We know that by the Law of Avogrado, for each mole of substance we have 6.02*10²³ atoms, if:

** Second Step: to know the molar mass of the solute

The molar mass of of magnesium = 24.30 g/mol

*** Third step: make the ratio mass / mol with atoms

1 mol we have 6.02*10²³ atoms

1 mole of Mg we have 24.30 g

Then we have:

24.30 g ------------- 6.02*10²³ atoms

x ----------------------- 6.98*10^24 atoms

\dfrac{24.30}{x} = \dfrac{6.02*10^{23}}{6.98*10^{24}}

multiply cross

6.02*10^{23}*x = 24.30*6.98*10^{24}

6.02*10^{23}\:x = 1.69614*10^{26}

x = \dfrac{1.69614*10^{26}}{6.02*10^{23}}

\boxed{\boxed{x \approx 281.75\:grams}}\end{array}}\qquad\checkmark

I Hope this helps, greetings ... DexteR! =)
